Opinion

KENNARD, J.                     section 2802, subdivision (a), requires an
                         Labor Code
employer to indemnify its employees for expenses they necessarily incur in
                                                                                          559


the discharge of their duties.1 May an employer satisfy this statutory obliga-
tion by paying employees increased wages or commissions instead of sepa-
rately reimbursing them for their actual expenses?

   We conclude that an employer may satisfy its statutory reimbursement
obligation by paying employees enhanced compensation in the form of
increases in base salary or increases in commission rates, or both, provided
there is a means or method to apportion the enhanced compensation to
determine what amount is being paid for labor performed and what amount is
reimbursement for business expenses.

   As we will explain, our conclusion differs somewhat from that reached by
the trial court and the Court of Appeal, and the differences affect the analysis
of another issue presented here, whether the trial court abused its discretion in
denying class certification. Accordingly, we reverse the Court of Appeal’s
judgment and remand the matter to that court for further proceedings
consistent with our opinion.

                                              I

   Defendant Harte-Hanks Shoppers, Inc. (Harte-Hanks), is a California cor-
poration that prepares and distributes advertising booklets and leaflets in
California, including the PennySaver and the California Shopper. The com-
pany is organized geographically in three business units: the Northern
California unit, the Southern California unit, and the San Diego unit. To sell
advertising space in its publications, Harte-Hanks employs both outside
and inside sales representatives. Outside sales representatives meet customers
in person at their places of business in assigned geographical territories,
while inside sales representatives contact customers by telephone. Outside
sales representatives must drive their own automobiles to contact customers,
while inside sales representatives work in their employer’s offices using
employer-owned telephone equipment. Harte-Hanks compensates both out-
side and inside sales representatives by commissions on advertising sales or
by a combination of base salary and commissions. With few exceptions,2
Harte-Hanks does not separately reimburse outside sales representatives for
their automobile expenses.
  1 Unless otherwise stated, all further statutory references are to the Labor Code.
  2 For the first few months after being hired in the San Diego unit, an outside          sales
representative is reimbursed for vehicle expenses by submitting mileage expense reports. In the
Southern California unit, some compensation plans include a $50 biweekly mileage payment
that is included in the base or guarantee. Also, within each unit, some outside sales
representatives have individually negotiated compensation agreements, which may include
periodic car allowances or business expense packages.

   Plaintiff Frank Gattuso is an outside sales representative in Harte-Hanks’s
Southern California unit. Plaintiff Ernest Sígala was an outside sales repre-
sentative in the same unit until January 2000, when his employment with
Harte-Hanks terminated. They brought this action on behalf of themselves
and other Harte-Hanks outside sales representatives seeking indemnification
under section 2802 for expenses incurred in using their own automobiles to
perform their employment duties. In response to the complaint, Harte-Hanks
took the position that it satisfies its obligation under section 2802 to
compensate outside sales representatives for automobile expenses by paying
them higher base salaries and higher commission rates than it pays to inside
sales representatives.3

   The trial court asked the parties to brief this issue: “Does Labor Code
section 2802 permit an employer to pay increased wages or commissions
instead of indemnifying actual expenses necessarily incurred in the discharge
of an employee’s duties?” After receiving briefing and hearing oral argument,
the trial court issued an order accepting Harte-Hanks’s argument that section
2802 permits an employer to pay increased salaries or commissions instead of
separately reimbursing the employee for actual expenses necessarily incurred
in discharging employment duties. The trial court further concluded that the
amount or rate of reimbursement could be determined by agreement between
employer and employee or, in the absence of an agreement, could be any
reasonable amount.

   Plaintiffs then moved the trial court (1) to certify a plaintiff class defined as
all current and former Harte-Hanks outside sales representatives who were
not reimbursed for the expenses they incurred in using their own automobiles
after January 1, 1998, to discharge their employment duties; (2) to certify
themselves as the class representatives; and (3) to appoint their attorneys as
class counsel. After receiving evidence in the form of declarations and
depositions, the trial court denied the motion for class certification. The court
took the view that plaintiffs had not shown common questions of fact and
law, giving this explanation: “Plaintiffs’ claim for unpaid business expenses
under [section 2802] turns on the determination of two issues (1) whether
each individual Harte-Hanks outside sales representative has an agreement
about the manner in which he is compensated for expenses, or (2) whether
the compensation paid to each individual sales representative is reasonable to
compensate for business expenses incurred. The determination of whether
there was a meeting of the minds and whether reimbursement was reasonable
  3 In the trial court,
                      Harte-Hanks argued in the alternative that section 2802 did not require
employers to reimburse employees “for routine expenses of employment such as car ex-
penses,” but only for losses caused by third parties. Both the trial court and the Court of
Appeal rejected that argument, and Harte-Hanks does not assert it in this court. Accordingly,
we do not address it here.
                                                                                            561


necessarily requires an individualized inquiry as to each outside sales repre-
sentative. The requirement of commonality therefore is not met, and Plain-
tiffs’ claim for unpaid business expenses cannot be maintained as a class
action.”

    Plaintiffs appealed from the order denying class certification, and on appeal
they also challenged the earlier order interpreting section 2802. The Court of
Appeal affirmed, agreeing with the trial court’s interpretation of section 2802
and concluding that the trial court did not abuse its discretion in denying
plaintiffs’ motion for class certification. The Court of Appeal denied plain-
tiffs’ petition for rehearing, and we granted plaintiffs’ petition for review.

                                               II

   Section 2802, subdivision (a), provides: “An employer shall indemnify his
or her employee for all necessary expenditures or losses incurred by the
employee in direct consequence of the discharge of his or her duties, or of his
or her obedience to the directions of the employer, even though unlawful,
unless the employee, at the time of obeying the directions, believed them to
be unlawful.” Subdivision (c) of section 2802 defines “ ‘necessary expendi-
tures or losses’ ” as including “all reasonable costs . . . .”

   A related provision, section 2804, expressly prohibits waiver of the rights
afforded under section 2802. Section 2804 provides: “Any contract or agree-
ment, express or implied, made by any employee to waive the benefits of this
article or any part thereof, is null and void, and this article shall not deprive
any employee or his personal representative of any right or remedy to which
he is entitled under the laws of this State.”

      A.    Legislative History

   Sections 2802 and 2804 were enacted in 1937 as part of the original Labor
Code.4 (Stats. 1937, ch. 90, pp. 185, 258-259.) Section 2802 was derived
from former section 1969 of the Civil Code, which had been enacted in
1872.5 Section 2804 was derived from a 1907 amendment to former section
1970 of the Civil Code. (Stats. 1907, ch. 97, § 1, p. 120.) In 2000, the
   4 As enacted in 1937, section 2802 read: “An employer shall indemnify his employee for all
that the employee necessarily expends or loses in direct consequence of the discharge of his
duties as such, or of his obedience to the directions of the employer, even though unlawful,
unless the employee, at the time of obeying such directions, believed them to be unlawful.”
(Stats. 1937, ch. 90, pp. 185, 258.)
   5 As first enacted in 1872, former section 1969 of the Civil Code provided: “An employer
must indemnify his employé, except as prescribed in the next section, for all that he necessarily
562


Legislature amended section 2802 to its present form. (Stats. 2000, ch. 990,
§ 1.) Section 2804 has not been amended since its enactment in 1937.

   At the time of the 2000 amendment of section 2802, legislative committee
analyses identified the purpose of that provision: “The author [of the amend-
ing legislation] states that Section 2802 is designed to prevent employers
from passing their operating expenses on to their employees. For example, if
an employer requires an employee to travel on company business, the
employer must reimburse the employee for the cost of that travel under
Section 2802.” (Sen. Rules Com., Off. of Sen. Floor Analyses, Analysis of
Sen. Bill No. 1305 (1999-2000 Reg. Sess.) as amended Aug. 18, 2000, p. 3.)

      B.   Appellate Decisions Construing or Applying Section 2802

   Relatively few appellate decisions have construed or applied section 2802,
and none of those decisions has much relevance to the issue here. Not
relevant here, for example, are decisions concerning an employer’s obligation
under section 2802 to pay legal expenses that an employee incurs in
defending a third party action based on the employee’s job-related conduct.
(E.g., Plancarte v. Guardsmark (2004) 118 Cal.App.4th 640, 647-648 [13
Cal.Rptr.3d 315]; Jacobus v. Krambo Corp. (2000) 78 Cal.App.4th 1096,
1100-1101 [93 Cal.Rptr.2d 425]; Devereaux v. Latham & Watkins (1995) 32
Cal.App.4th 1571, 1583 [38 Cal.Rptr.2d 849]; Grissom v. Vons Companies,
Inc. (1991) 1 Cal.App.4th 52, 56-59 [1 Cal.Rptr.2d 808]; Douglas v. Los
Angeles Herald-Examiner (1975) 50 Cal.App.3d 449, 457-461 [123 Cal.Rptr.
683].) Also unhelpful here are decisions concerning section 2802’s applica-
tion to public entity employers. (E.g., In re Work Uniform Cases (2005) 133
Cal.App.4th 328, 345 [34 Cal.Rptr.3d 635] [public entities not required to pay
the cost of employee uniforms]; Los Angeles Police Protective League v. City
of Los Angeles (1994) 27 Cal.App.4th 168, 171 [32 Cal.Rptr.2d 574] [public
entities not required to pay expenses for defending criminal charges].)

  Also of doubtful relevance are other decisions concerning nonrecurring
business expenses. For example, in Machinists Automotive Trades Disk
Lodge v. Utility Trailers Sales Co. (1983) 141 Cal.App.3d 80 [190 Cal.Rptr.
98], the Court of Appeal held that when “the custom of the trade requires the

expends or loses in direct consequence of the discharge of his duties as such, or of his
obedience to the directions of the employer, even though unlawful, unless the employé, at the
time of obeying such directions, believed them to be unlawful.”
   The referenced “next section” was former section 1970 of the 1872 Civil Code, which
originally read: “An employer is not bound to indemnify his employé for losses suffered by the
latter in consequence of the ordinary risks of the business in which he is employed, nor in
consequence of the negligence of another person employed by the same employer in the same
general business, unless he has neglected to use ordinary care in the selection of the culpable
employé.”
                                                                           563


employee to supply his own tools” and the tools were “too heavy to be
transported routinely to and from the place of employment,” section 2802
required the employer to reimburse the employee for the loss suffered when
the employee’s tools were stolen from the employer’s premises. (Machinists
Automotive Trades Dist. Lodge v. Utility Trailers Sales Co., supra, at p. 86.)
That case disagreed with an earlier Court of Appeal decision (Earll v. McCoy
(1953) 116 Cal.App.2d 44 [253 P.2d 86]) that had reached the opposite
conclusion in a similar situation, where the employee’s tools were destroyed
by a fire on the employer’s premises. (Machinists Automotive Trades Dist.
Lodge v. Utility Trailers Sales Co., supra, at p. 83.)

     C. Administrative Construction and Enforcement

   The Division of Labor Standards Enforcement (DLSE) is the state agency
authorized to enforce California’s labor laws. (Reynolds v. Bement (2005) 36
Cal.4th 1075, 1084 [32 Cal.Rptr.3d 483, 116 P.3d 1162]; Morillion v. Royal
Packing Co. (2000) 22 Cal.4th 575, 581 [94 Cal.Rptr.2d 3, 995 P.2d 139].)
The Labor Commissioner is the chief of the DLSE. (§§ 79, 82.) In 1996, this
court held that all of the DLSE’s interpretive policies contained in its 1989
operations and procedures manual were regulations that were void because
they had not been promulgated in compliance with the Administrative
Procedure Act (Gov. Code, § 11340 et seq.). (Tidewater Marine Western,
Inc. v. Bradshaw (1996) 14 Cal.4th 557, 572 [59 Cal.Rptr.2d 186, 927 P.2d
296].) We also concluded that insofar as the void regulations reflected the
DLSE’s statutory interpretations, those interpretations were entitled to no
deference. (Id. at pp. 576-577.) Nonetheless, we said, a court may adopt a
DLSE statutory interpretation embodied in a void regulation if the court
independently determines that the interpretation is correct. (Id. at p. 577.)

  Here, as the parties agree, the DLSE’s interpretation of section 2802, as
applied to automobile expenses, was incorporated into a void regulation.
Accordingly, we review the relevant DLSE policy statements and DLSE
advice and opinion letters as evidence of the DLSE’s interpretation of sections
2802 and 2804, recognizing that its interpretation is entitled to no deference
but also that this court may adopt the DLSE’s interpretation if we indepen-
dently determine that it is correct.

  1. Interpretive Bulletin No. 84-7

   On January 8, 1985, the Labor Commissioner issued a revision to Interpre-
tive Bulletin No. 84-7. As relevant here, it stated: “Under Labor Code Section
2802, an employer who requires an employee to furnish his/her own car or
truck to be used in the course of employment would be obligated to
reimburse the employee for the costs necessarily incurred by the employee in
564


using the car or truck in the course of employment. The rate of reimburse-
ment can be that agreed to by the employer and employee, or, if there is no
such agreement, any reasonable amount.” (Ibid.)

           2.   Opinion Letter No. 1993.02.22-3

   On February 22, 1993, H. Thomas Cadell, Jr., as DLSE Chief Counsel,
wrote an advice letter to an attorney. As relevant here, it stated: “[T]he
payment of a reasonable mileage reimbursement covers all reasonable operat-
ing costs incurred by the employee in the operation of the vehicle. The DLSE
accepts the mileage reimbursement used by the IRS as reasonable. Those
operating costs would include damages or loss due to accident or theft unless
the damage to or the loss of the vehicle due to accident or theft was the result
of the negligence of the employer. HI] • ■ ■ HQ ■ ■• In the absence of an
agreement to pay a reasonable mileage reimbursement, the employer would
be required to reimburse the employee for the actual costs incurred in
operating the vehicle while that vehicle was being used in the service of the
employer. Those costs would include, of course, losses due to accident or
theft while the vehicle is being used for the purposes of the employer.”

           3.   July 1993 DLSE Update

   The DLSE embodied the substance of the February 22, 1993, opinion letter
in a bulletin update issued in July 1993. It reads:

   “[T]he payment of a reasonable mileage reimbursement covers all reason-
able operating costs incurred by the employee in the operation of a personal
vehicle for business purposes. The DLSE accepts the mileage reimbursement
used by the IRS as reasonable. Those operating costs would include damages
or loss due to accident or theft, unless the damage or loss was the direct
result of the negligence of the employer.

   “In the absence of an agreement to pay a reasonable mileage reimburse-
ment, the employer would be required to reimburse the employee for the
actual costs incurred in operating the vehicle while that vehicle was being
used in the service of the employer. Those costs would include losses due to
accident or theft while the vehicle is being used for business purposes.”

           4.   Opinion Letter No. 1994.08.14

  On August 14, 1994, H. Thomas Cadell, Jr., as DLSE Chief Counsel, wrote
an opinion letter to an attorney to clarify and confirm a previous telephone
conversation. As relevant here, the letter stated: “I stated, I am sure, that the
DLSE has long recognized the IRS rate for automobile reimbursement as a
                                                                            565


presumptively reasonable rate. . . . The policy of the DLSE continues to be
that the IRS rate is presumptively reasonable for purposes of reimbursement
of automobile expenses.”

           5.   Opinion Letter No. 1998.11.05

   On November 5, 1998, Michael S. Villeneuve, as DLSE Staff Counsel,
wrote an opinion letter to respond to a question asking whether Labor Code
section 2802 requires employers “to reimburse employees for automobile
insurance premiums for coverage above the legal minimum.” As relevant
here, the letter stated:

   “As long as the employer reimburses the employee for the cost of the
insurance and does not dictate which company supplies the insurance, the
Labor Code does not prevent the employer you describe from requiring its
employees to obtain insurance coverage beyond the legal minimum. Those
expenses which an employer causes an employee to incur, however, must be
reimbursed, since Labor Code § 2802 requires that the employer indemnify
the employee for such loss or expenditure which is in direct consequence of
the discharge of his duties. Thus the question becomes whether a ‘reasonable’
mileage reimbursement covers operating expenses incurred.

   “The application of the Internal Revenue Service mileage allowance as a
deduction from income for taxation purposes, which has been previously
viewed by DLSE as ‘reasonable’ as a measure of expenses, is not dispositive
with respect to the issue of indemnification of expenses actually incurred. The
IRS figure is a national average of the costs of operating a motor vehicle
without respect to initial cost of purchase or lease (which affects depreciation
allowance), repairs and maintenance, fluctuating fuel costs, and, of course,
cost of insurance, which varies widely state to state, and locality to locality.

   “Prior enforcement of Section 2802 where employers paid less than the
IRS mileage rate viewed such compensation as being rebuttably presumed not
to comply with Section 2802. Thus, if the employer could prove that the
actual costs incurred by the employee were less than the IRS rate, no
violation of Section 2802 occurs if the employee is indemnified for actual
expenses incurred. Conversely, payment of the IRS allowance rate confers no
irrebuttable presumption of compliance with Section 2802. Rather, the burden
shifts to the employee to prove that actual expenses incurred exceeded the
amount tendered by the employer. If the employee successfully demonstrates
that additional insurance coverage raises the cost of operating the vehicle
beyond the IRS mileage figure, the employer will be obligated to cover such
costs. Naturally this determination must be made on a case by case basis, as
insurance costs will vary depending on the domicile and use locations.
566


   “Thus while the Division generally finds the IRS mileage rate as reim-
bursement to be reasonable, no overall exemption from liability under Section
2802 can be given. Since the IRS mileage rate is based, in part, on average
costs of insurance premiums as applied to drivers with average driving
records, a particular driver may be able to demonstrate that higher costs were
necessarily incurred in the purchase of such insurance.” (Fn. omitted.)

           6.   Letter Dated September 12, 2000

   On September 12, 2000, Patricia K. Huber, as Deputy Labor Commissioner,
wrote a letter to a corporation’s general counsel. As relevant here, the letter
stated: “The cost of operating a vehicle is a reimbursable expense under Labor
Code Section 2802. If there is no specific agreement as to the mileage rate, the
IRS rate is considered reasonable and is used. Otherwise, the employer is
responsible for the actual costs incurred in operating the vehicle.”

           7.   Letter Dated December 27, 2005

   On December 27, 2005, Anne Hipsham, as Staff Counsel for the Labor
Commissioner, wrote a letter to this court urging depublication of the Court
of Appeal’s opinion in this case. In relevant part, the letter stated:

   “The Labor Commissioner has developed an enforcement position that the
Internal Rev[en]ue Service (IRS) rate of reimbursement is the acceptable
level for reimbursement of mileage for an employee’s use of a personal
vehicle. . . . [f] The DLSE reached this conclusion after many decades of
enforcement in the area of reimbursement for mileage for personal vehicles
required to be driven for work-related activities, because of the difficulty in
accurately determining the precise amount an employee should be reimbursed
for purposes of meeting the indemnification language contained in Section
2802.

   “The mileage reimbursement rate is compiled by the IRS by taking into
account all factors involved with the use of a vehicle: fuel, maintenance,
repairs, depreciation, insurance, etc. by annually conducting a national survey
and coming up with appropriate averages.

   “The DLSE enforcement position also allows for a deviation from the IRS
rate where appropriate. If an employer wants to pay less than this established
IRS rate, the employer bears the burden of proving that the employee’s costs
of operating the vehicle for work is actually less. If the employee seeks a rate
of reimbursement higher than the IRS rate, the employee bears ... the burden
[of] proving that his or her actual operating costs are higher.”
                                                                             567


                                       III

         When construing a statute, a court’s goal is “to ascertain the intent of
the enacting legislative body so that we may adopt the construction that best
effectuates the purpose of the law.” (Hassan v. Mercy American River Hospital
(2003) 31 Cal.4th 709, 715 [3 Cal.Rptr.3d 623, 74 P.3d 726]; accord,
Coachella Valley Mosquito & Vector Control Dist. v. California Public
Employment Relations Bd. (2005) 35 Cal.4th 1072, 1087 [29 Cal.Rptr.3d 234,
112 P.3d 623].) Generally, the court first examines the statute’s words, giving
them their ordinary and usual meaning and viewing them in their statutory
context, because the statutory language is usually the most reliable indicator
of legislative intent. (Hassan v. Mercy American River Hospital, supra, at
p. 715; accord, City of Burbank v. State Water Resources Control Bd. (2005)
35 Cal.4th 613, 625 [26 Cal.Rptr.3d 304, 108 P.3d 862].)


         When the statutory language is ambiguous, a court may consider the
consequences of each possible construction and will reasonably infer that the
enacting legislative body intended an interpretation producing practical and
workable results rather than one producing mischief or absurdity. “Our
decisions have long recognized that a court’s ‘overriding purpose’ in constru-
ing a statute is ‘to give the statute a reasonable construction conforming to
[the Legislature’s] intent [citation] . . .     (Copley Press, Inc. v. Superior
Court (2006) 39 Cal.4th 1272, 1299, fn. 22 [48 Cal.Rptr.3d 183, 141 P.3d
288], quoting Massey v. Workers’ Comp. Appeals Bd. (1993) 5 Cal.4th 674,
681 [20 Cal.Rptr.2d 825, 854 P.2d 117], original italics.) “The court will
apply common sense to the language at hand and interpret the statute to make
it workable and reasonable.” (Wasatch Property Management v. Degrate
(2005) 35 Cal.4th 1111, 1122 [29 Cal.Rptr.3d 262, 112 P.3d 647].) “When a
statute is capable of more than one construction, ‘ “[w]e must . . . give the
provision a reasonable and commonsense interpretation consistent with the
apparent purpose and intention of the lawmakers, practical rather than
technical in nature, which upon application will result in wise policy rather
than mischief or absurdity.” ’ ” (In re Reeves (2005) 35 Cal.4th 765, 771, fn. 9
[28 Cal.Rptr.3d 4, 110 P.3d 1218], quoting Renee J. v. Superior Court (2001)
26 Cal.4th 735, 744 [110 Cal.Rptr.2d 828, 28 P.3d 876], quoting
Marshall M. v. Superior Court (1999) 75 Cal.App.4th 48, 55 [88 Cal.Rptr.2d
891].)

   Here, the parties agree that section 2802, which requires an employer to
indemnify its employees for expenses they necessarily incur in the discharge
of their duties, requires Harte-Hanks to fully reimburse its outside sales
representatives for the automobile expenses they actually and necessarily
incur in performing their employment tasks. They disagree only on whether
568


section 2802 permits an employer to do so through an increase in overall
compensation rather than through a separately identified reimbursement
payment.


   The parties agree that one method an employer may use for automobile
expense reimbursement is to calculate the automobile expenses that the
employee actually and necessarily incurred and then to separately pay the
employee that amount. This actual expense method is the most accurate, but
it is also the most burdensome for both the employer and the employee. The
actual expenses of using an employee’s personal automobile for business
purposes include fuel, maintenance, repairs, insurance, registration, and de-
preciation. To calculate the reimbursement amount using the actual expense
method, therefore, the employee must keep detailed and accurate records of
amounts spent in each of these categories. Calculation of depreciation will
require information about the automobile’s purchase price and resale value
(or lease costs). In addition, the employee must keep records of the informa-
tion needed to apportion those expenses between business and personal use.
This is generally done by separately recording the miles driven for business
and personal use. The employee then must submit all of this information to
the employer for calculation of the reimbursement amount due.


         In calculating the reimbursement amount due under section 2802, the
employer may consider not only the actual expenses that the employee
incurred, but also whether each of those expenses was “necessary,” which in
turn depends on the reasonableness of the employee’s choices. (See Grissom v.
Vons Companies, Inc., supra, 1 Cal.App.4th at p. 58 [under § 2802, “ascer-
taining what was a necessary expenditure will require an inquiry into what
was reasonable under the circumstances”].) For example, an employee’s
choice of automobile will significantly affect the costs incurred. An employee
who chooses an expensive model and replaces it frequently will incur
substantially greater depreciation costs than an employee who chooses a
lower priced model and replaces it less frequently. Similarly, some vehicles
use substantially more fuel or require more frequent or more costly mainte-
nance and repairs than others. The choice of vehicle will also affect insurance
costs. Other employee choices, such as the brand and grade of gasoline or
tires and the shop performing maintenance and repairs, will also affect the
actual costs. Thus, calculation of automobile expense reimbursement using
the actual expenses method requires not only detailed recordkeeping by the
 employee and complex allocation calculations, but also the exercise of
judgment (by the employer, the employee, and officials charged with enforce-
ment of § 2802) to determine whether the expenses incurred were reasonable
and therefore necessary.
                                                                          569


   Because of the onerous burdens that the actual expense method imposes on
both employer and employee, few employers use this method to determine
reimbursement for work-required use of employees’ own automobiles, and
both parties here agree that the actual expense method is not the only method
that an employer may use to satisfy its reimbursement obligations under
section 2802. Both parties agree that an employer may also use the mileage
reimbursement method.

         When an employer uses the mileage reimbursement method to deter-
mine the amount of reimbursement due under section 2802 for work-required
use of an employee’s own automobile, the employee need only keep a record
of the number of miles driven to perform job duties. The employee submits
that information to the employer, who then multiplies the work-required miles
driven by a predetermined amount that approximates the per-mile cost of
owning and operating an automobile. As indicated in the DLSE opinion
letters and policy statements previously quoted, the federal Internal Revenue
Service (IRS) has calculated an automobile mileage rate for federal income
tax purposes, based on national average expenses for fuel, maintenance,
repair, depreciation, and insurance, and this IRS mileage rate is also widely
used and accepted by private business employers for calculating reimbursable
employee automobile expenses. Here, both parties agree that section 2802
permits use of the IRS mileage rate to calculate automobile expense reim-
bursement under the mileage reimbursement method.


        Because a mileage rate used in the mileage reimbursement method is
merely an approximation of actual expenses, the mileage reimbursement
method is inherently less accurate than the actual expense method. Because
section 2802 requires the employer to fully reimburse the employee for all
expenses actually and necessarily incurred, both parties here agree that if an
employer uses the mileage reimbursement method, the employee must be
permitted to challenge the resulting reimbursement payment. If the employee
can show that the reimbursement amount that the employer has paid is less
than the actual expenses that the employee has necessarily incurred for
work-required automobile use (as calculated using the actual expense
method), the employer must make up the difference.


        The DLSE interpretive bulletin (see, ante, at p. 563) said that the
mileage rate could be set by agreement of the parties, and the trial court
stated that it independently reached the same conclusion. We agree that, as
with other terms and conditions of employment, a mileage rate for automo-
bile expense reimbursement may be a subject of negotiation and agreement
between employer and employee. Under section 2804, however, any agree-
ment made by the employee is null and void insofar as it waives the
570



employee’s rights to full expense reimbursement under section 2802. There-
fore, the existence of an agreement concerning a mileage reimbursement rate
would not relieve the employer of the statutory obligation to provide com-
plete reimbursement, nor would it preclude an employee from challenging the
sufficiency of a reimbursement payment that was calculated using the agreed
mileage rate.

         Another automobile expense reimbursement method is the use of a
 lump-sum payment. Under this method, the employee need not submit any
information to the employer about work-required miles driven or automobile
expenses incurred. The employer merely pays a fixed amount for automobile
expense reimbursement. The fixed amount may take various forms and have
various labels, including per diem, car allowance, and gas stipend. The
amount is generally based on the employer’s understanding of the employee’s
job duties, including the number of miles that the employee typically or
routinely must drive to perform those duties. Although the parties here agree
that an employer may use either the actual expense method or the mileage
reimbursement method, they do not agree on whether section 2802 permits an
employer to use a lump-sum method to reimburse employee automobile
expenses.

   Plaintiffs contend that section 2802 does not permit an employer to use the
lump-sum method for automobile expense reimbursement. They argue that
“compliance with section 2802 requires that an employer must correlate the
employee’s reimbursement to the incurred expenses” because “[c]orrelation is
necessary to guarantee reimbursement of employee expenses.” Harte-Hanks
argues, to the contrary, that section 2802 does not require employers to use a
“correlated” reimbursement plan, that section 2802 does not restrict the
methods by which the employer may calculate reimbursement, and that section
2802 requires only that whatever method is used results in full reimbursement
for actual expenses necessarily incurred by the employee.


         We agree with Harte-Hanks, and also with the trial court and the
Court of Appeal, that section 2802 does not prohibit an employer’s use of a
lump-sum method to reimburse employees for work-required automobile
expenses, provided that the amount paid is sufficient to provide full reim-
bursement for actual expenses necessarily incurred. Nothing in the language
of section 2802 restricts the methods that an employer may use to calculate
reimbursement, and we are required to construe section 2802 in a manner that
produces a workable and reasonable result. If, for example, an employee
                                                                            571


drives exactly the same route day after day, so that the mileage driven varies
little if at all from one day to the next, it would be unreasonable to require a
meticulous record of actual miles driven. In that situation, an employer
should be able to dispense with actual mileage reports and calculate a
lump-sum payment based on the employer’s knowledge of the distances that
an employee must drive to perform the duties of the employee’s job.


   In support of their argument that section 2802 requires a method of
automobile expense reimbursement that is “correlated” to actual expenses
incurred or miles driven, plaintiffs cite no authority apart from section 2802
itself. They argue only that correlation is necessary to allow effective
enforcement of employees’ rights under section 2802.


        Of course, an employee must be permitted to challenge the amount of
a lump-sum payment as being insufficient under section 2802. An employee
may do so by comparing the payment with the amount that would be payable
under either the actual expense method or the mileage reimbursement
method. If the comparison reveals that the lump sum is inadequate, the
employer must make up the difference. As with mileage rates, an employer
and an employee may agree on a particular lump sum to be paid as
automobile reimbursement. But, under section 2804, the existence of an
agreement between an employer or employee regarding a lump-sum reim-
bursement payment would not relieve the employer of the statutory obligation
to pay full reimbursement, nor would it bar an employee challenge to a
lump-sum payment as being insufficient under section 2802 to provide full
reimbursement.


         As Harte-Hanks points out, an employer’s decision to use a lump--
sum method rather than a mileage reimbursement system may have income
tax consequences, affecting whether the resulting payments are exempt from
withholding requirements (see, e.g., Shotgun Delivery, Inc. v. U.S. (9th Cir.
2001) 269 F.3d 969, 972-973) and, ultimately, the extent to which they are
taxable as income or instead treated as deductible business expenses. We
agree with Harte-Hanks, however, that section 2802 does not require an
employer to use a reimbursement method that is congruent with any tax law
or has any particular tax consequence. Of course, as Harte-Hanks concedes,
and as the Court of Appeal also concluded, any tax consequences that result
from the employer’s choice of reimbursement method should be considered
in determining whether a particular payment provides the full measure of
reimbursement that section 2802 requires.
572


  Having concluded     that section 2802 permits     an employer’s   use of a
lump-sum method to reimburse an employee for work-required automobile
expenses, we next consider whether the employer must segregate the lump
sum from other compensation or whether, as the trial court and the Court of
Appeal concluded, the employer instead may pay the lump sum in the form
of an increase to the employee’s base salary or commissions. Plaintiffs argue
that the reimbursement amount must be kept entirely separate from salary and
commissions, for these reasons: (1) the statutory definition of “wages” in
section 200 excludes reimbursement payments; (2) section 226, which re-
quires employers to itemize their wage payments, does not contemplate
inclusion of business expense reimbursement within wage payments; and
(3) allowing business expense reimbursement payments to be combined with
wage payments contradicts the DLSE’s long-standing interpretation of section
2802. We consider these objections in turn.

   Plaintiffs argue first that expense reimbursements cannot b.e wages, and
reimbursement payments therefore must be separated from base salary and
commissions. They rely on section 200, subdivision (a), which states that
“[a]s used in this article . . . ‘[w]ages’ includes all amounts for labor
performed by employees of every description, whether the amount is fixed or
ascertained by the standard of time, task, piece, commission basis, or other
method of calculation.” (Italics added.) Plaintiffs argue that because wages
are paid “for labor performed” whereas payments under section 2802 are
reimbursement for work-required expenses the employee has incurred, a
wage payment, whether in the form of salary or commission, cannot be used
to discharge an employer’s obligation under section 2802.

   Section 200 highlights a valid and important distinction between wages (as
payment for labor performed) and business expense reimbursement. The
amount payable as wages is subject to various statutory restrictions, including
minimum wage laws, which operate independently of, and in addition to,
section 2802’s obligation of an employer to fully reimburse an employee’s
necessary business expenses. The amount payable as wages may also be fixed
by a contract of employment, and contractual agreements regarding employee
compensation may or may not include specific terms governing business
expense reimbursement. Because wages and expense reimbursement are
conceptually distinct and subject to different statutory and sometimes also
contractual constraints, an employer may not combine the payments for both
in a way that would seriously hamper or effectively preclude enforcement of
the various statutory and contractual obligations.

   This does not mean, however, that an employer is prohibited from combin-
ing wages and business expense reimbursements in a single enhanced em-
ployee compensation payment or from discharging its section 2802 business
                                                                          573


expense reimbursement obligation through an increase in base salary or in
commission rates (or an increase in both salary and commission rates). It
simply means that the employer must provide some method or formula to
identify the amount of the combined employee compensation payment that is
intended to provide expense reimbursement. Using that method or formula,
the employee (and also officials charged with enforcement of state and federal
wage laws) then can readily determine whether the employer has discharged
all of its legal obligations as to both wages and business expense reimburse-
ment. Although section 2802 does not expressly require the employer to
provide an apportionment method, it is essential that employees and officials
charged with enforcing the labor laws be able to differentiate between wages
and expense reimbursements. Because providing an apportionment method is
a practical necessity for effective enforcement of section 2802’s reimburse-
ment provisions, it is implicit in the statutory scheme.

   An employer that chooses to link expense reimbursement to employee
performance by providing automobile expense reimbursement through an
increase in commission rates, as Harte-Hanks alleges it has done, runs a risk
that the employee, for whatever reason, may earn less commission income
than the employer anticipated, so that the increase in the commission rate
may be insufficient to provide full reimbursement for the automobile ex-
penses that the employee necessarily incurred. If that happens, the employer’s
full reimbursement obligation under section 2802 will require it to make up
the difference. Harte-Hanks concedes that this is so. This is not a reason,
however, to conclude that section 2802 prohibits this method of business
expense reimbursement.

   We next consider plaintiffs’ argument that providing section 2802 automo-
bile expense reimbursement through enhanced employee compensation, in the
form of increases in base salary and/or commission rates, would violate or be
inconsistent with an employer’s obligation under section 226, subdivision (a),
to itemize employee compensation payments. Section 226, subdivision (a),
provides: “Every employer shall, semimonthly or at the time of each payment
of wages, furnish each of his or her employees, either as a detachable part of
the check, draft, or voucher paying the employee’s wages, or separately when
wages are paid by personal check or cash, an accurate itemized statement in
writing showing (1) gross wages earned, (2) total hours worked by the
employee, except for any employee whose compensation is solely based on a
salary and who is exempt from payment of overtime under subdivision (a) of
Section 515 or any applicable order of the Industrial Welfare Commission,
(3) the number of piece-rate units earned and any applicable piece rate if the
employee is paid on a piece-rate basis, (4) all deductions, provided that all
deductions made on written orders of the employee may be aggregated and
shown as one item, (5) net wages earned, (6) the inclusive dates of the period
for which the employee is paid, (7) the name of the employee and his or her
574


social security number, except that by January 1, 2008, only the last four
digits of his or her social security number or an employee identification
number other than a social security number may be shown on the itemized
statement, (8) the name and address of the legal entity that is the employer,
and (9) all applicable hourly rates in effect during the pay period and the
corresponding number of hours worked at each hourly rate by the employee.
The deductions made from payments of wages shall be recorded in ink or
other indelible form, properly dated, showing the month, day, and year, and a
copy of the statement or a record of the deductions shall be kept on file by
the employer for at least three years at the place of employment or at a
central location within the State of California.”

  We find nothing in the language of section 226, subdivision (a), that
prohibits an employer from discharging its reimbursement obligations under
section 2802 by increases in base salary or commission rates. Section 226,
subdivision (a), requires the employer to document the basis of the employee
compensation payments, including the gross wages earned, the hours worked,
the number of piece-rate units earned, and each deduction taken. As we have
explained, an employer that uses salary and/or commission increases to
discharge its reimbursement obligation must also communicate to its employ-
ees the method or basis for apportioning any increases in compensation
between compensation for labor performed and business expense reimburse-
ment. Such a requirement, as noted, is necessary for effective enforcement of
section 2802’s reimbursement provisions and, thus, implicit in the statutory
scheme.6

   Plaintiffs argue, finally, that allowing an employer to combine business
expense reimbursement with payments for labor performed contradicts the
DLSE’s long-standing interpretation of section 2802. As we have explained,
however, the DLSE’s interpretation of section 2802, because it was embodied
in a void regulation, is not entitled to deference. (Tidewater Marine Western,
Inc. v. Bradshaw, supra, 14 Cal.4th at pp. 576-577.) In any event, with the
exception of the DLSE letter urging depublication of the Court of Appeal’s
opinion in this case, none of the DLSE policy statements or opinion letters
that have been made part of the record in this case addresses the question at
issue here. Although the DLSE has endorsed both the actual expense method
and the mileage reimbursement method for discharging an employer’s obliga-
tions under section 2802, the DLSE has not, so far as we are aware,
considered or rejected other methods, such as the use of a lump-sum payment
   6 In the future, employers that provide business expense reimbursement to employees
through increases in base salary or commission rates should, in providing the documentation
required by section 226, subdivision (a), separately identify the amounts that represent
payment for labor performed and the amounts that represent reimbursement for business
expenses.
                                                                              575


or enhanced compensation in the form of an increase in base salary and/or
commission rates. Accordingly, the DLSE’s construction of section 2802, as
explained in the materials in the record before us, does not support plaintiffs’
position.

          We conclude that an employer may satisfy its statutory business
expense reimbursement obligation under section 2802 by paying employees
enhanced compensation in the form of increases in base salary or commission
rates, provided the employer establishes some means to identify the portion
of overall compensation that is intended as expense reimbursement, and
provided also that the amounts so identified are sufficient to fully reimburse
the employees for all expenses actually and necessarily incurred.

                                       IV

   The remaining issue is whether the trial court abused its discretion in
denying plaintiffs’ motion to certify a plaintiff class defined as all current and
former Harte-Hanks outside sales representatives who were not reimbursed
for the expenses they incurred in using their own automobiles after January 1,
1998, to discharge their employment duties.

          Under Code of Civil Procedure section 382, a class action is
permitted “when the question is one of a common or general interest, of
many persons, or when the parties are numerous, and it is impracticable to
bring them all before the court . . . .” Class certification requires both an
ascertainable class and a well-defined community of interest among class
members. (Sav-On Drug Stores, Inc. v. Superior Court (2004) 34 Cal.4th 319,
326 [17 Cal.Rptr.3d 906, 96 P.3d 194]; accord, Fireside Bank v. Superior
Court (2007) 40 Cal.4th 1069, 1089 [56 Cal.Rptr.3d 861, 155 P.3d 268].)
Here, the trial court concluded that plaintiffs had established an ascertainable
class but also that they had failed to satisfy the “community of interest”
requirement.

           “The ‘community of interest’ requirement embodies three factors:
(1) predominant common questions of law or fact; (2) class representatives
with claims or defenses typical of the class; and (3) class representatives who
can adequately represent the class.” (Sav-On Drug Stores, Inc. v. Superior
Court, supra, 34 Cal.4th at p. 326.) The trial court here concluded that
plaintiffs had failed to show the existence of predominant questions of law or
fact.

  The trial court’s ruling on the class certification motion is reviewed for
abuse of discretion. (Sav-On Drug Stores, Inc. v. Superior Court, supra, 34
Cal.4th at p. 326.) If supported by substantial evidence, a class certification
576


ruling “generally will not be disturbed ‘unless (1) improper criteria were used
                                                                              ”
[citation]; or (2) erroneous legal assumptions were made [citation].’
(Linder v. Thrifty Oil Co. (2000) 23 Cal.4th 429, 435-436 [97 Cal.Rptr.2d 179,
2 R3d 27]; accord, Sav-On Drug Stores, Inc. v. Superior Court, supra, at
pp. 326-327.)

   In concluding that common issues did not predominate here, the trial court
reasoned that plaintiffs’ claims under section 2802 would “tum[] on the
determination of two issues (1) whether each individual Harte-Hanks outside
sales representative has an agreement about the manner in which he is
compensated for expenses, or (2) whether the compensation paid to each
individual sales representative is reasonable to compensate for business
expenses incurred” and that both determinations would require “an individu-
alized inquiry as to each outside sales representative.”

   The class that plaintiffs sought to certify consisted of all Harte-Hanks
outside sales representatives “who were not reimbursed for the expenses they
incurred in using their own automobiles after January 1, 1998.” We construe
this to refer to the Harte-Hanks outside sales representatives who were not
separately reimbursed, apart from their base salary and commissions. Not
included in the proposed class, therefore, are the relatively few Harte-Hanks
outside sales representatives who received automobile expense reimburse-
ment through a separate payment, whether as the result of an individually
negotiated compensation package or otherwise. (See fn. 2, ante, at p. 559.)

   Harte-Hanks has taken the position that as to the members of this proposed
class, it fulfilled its reimbursement obligation under section 2802 by paying
them higher commission rates and higher base salaries than it paid to inside
sales representatives. As we explained in the previous section, the validity of
this claim will turn on the resolution of these questions: (1) Did Harte-Hanks
adopt a practice or policy of reimbursing outside sales representatives for
automobile expenses by paying them higher commission rates and base
salaries than it paid to inside sales representatives? (2) If so, did it establish a
method to apportion the enhanced compensation payments between compen-
sation for labor performed and expense reimbursement? (3) If so, was the
amount paid for expense reimbursement sufficient to fully reimburse the
employees for the automobile expenses they reasonably and necessarily
incurred?

           Neither the trial court nor the Court of Appeal framed the class
certification issue in that way, and so neither court considered whether these
inquiries are capable of resolution on a classwide basis. Accordingly, the class
certification issue is to be reconsidered upon remand.
                                                                              577


                                        V

  The judgment of the Court of Appeal is reversed, and the matter is
remanded to that court for further proceedings consistent with this court’s
opinion.
