____________________________________)

        Upon a request by the United States Court of Appeals for the Ninth Circuit
(Cal. Rules of Court, rule 8.548), we agreed to answer the following question:
Does the federal Fair Labor Standards Act’s de minimis doctrine, as stated in
Anderson v. Mt. Clemens Pottery Co. (1946) 328 U.S. 680, 692, and Lindow v.
United States (9th Cir. 1984) 738 F.2d 1057, 1063, apply to claims for unpaid
wages under California Labor Code sections 510, 1194, and 1197?
        The de minimis doctrine is an application of the maxim de minimis non
curat lex, which means “[t]he law does not concern itself with trifles.” (Black’s
Law Dict. (10th ed. 2014) p. 524.) Federal courts have applied the doctrine in
some circumstances to excuse the payment of wages for small amounts of
otherwise compensable time upon a showing that the bits of time are
administratively difficult to record.
        We approach the question presented in two parts: First, have California’s
wage and hour statutes or regulations adopted the de minimis doctrine found in the

                         SEE CONCURRING OPINIONS
federal Fair Labor Standards Act (FLSA)? We conclude they have not. There is
no indication in the text or history of the relevant statutes and Industrial Welfare
Commission (IWC) wage orders of such adoption.
       Second, does the de minimis principle, which has operated in California in
various contexts, apply to wage and hour claims? In other words, although
California has not adopted the federal de minimis doctrine, does some version of
the doctrine nonetheless apply to wage and hour claims as a matter of state law?
We hold that the relevant wage order and statutes do not permit application of the
de minimis rule on the facts given to us by the Ninth Circuit, where the employer
required the employee to work “off the clock” several minutes per shift. We do
not decide whether there are circumstances where compensable time is so minute
or irregular that it is unreasonable to expect the time to be recorded.
                                          I.
       The factual background, as recounted in the Ninth Circuit’s request for
certification unless otherwise indicated, is as follows: On August 6, 2012,
plaintiff Douglas Troester filed the original complaint in an action in Los Angeles
County Superior Court on behalf of himself and a putative class of all
nonmanagerial California employees of defendant Starbucks Corporation
(Starbucks) who performed store closing tasks from mid-2009 to October 2010.
Troester worked for Starbucks as a shift supervisor. Starbucks removed the action
to federal district court and moved for summary judgment on the ground that
Troester’s uncompensated time was so minimal that Starbucks was not required to
compensate him.
       Troester submitted evidence that during the alleged class period,
Starbucks’s computer software required him to clock out on every closing shift
before initiating the software’s “close store procedure” on a separate computer
terminal in the back office. The close store procedure transmitted daily sales,

                                          2
profit and loss, and store inventory data to Starbucks’s corporate headquarters.
After Troester completed this task, he activated the alarm, exited the store, and
locked the front door. Troester also submitted evidence that he walked his
coworkers to their cars in compliance with Starbucks’s policy. In addition,
Troester submitted evidence that he occasionally reopened the store to allow
employees to retrieve items they left behind, waited with employees for their rides
to arrive, or brought in store patio furniture mistakenly left outside.
       On March 7, 2014, the district court granted Starbucks’s motion for
summary judgment. The district court’s decision assumed that each activity
identified above was compensable for purposes of its analysis. The undisputed
evidence was that these closing tasks required Troester to work four to 10
additional minutes each day. As the district court stated: “The undisputed facts
show that, on average, Plaintiff activated the alarm approximately one minute after
he clocked out. Moreover, he did so within two minutes on 90 percent of the
shifts and within five minutes on every shift. Once he set the alarm, Plaintiff
needed to exit the store within one minute to avoid triggering the alarm. And
Plaintiff testified that it took 30 seconds to walk out of the store. He then locked
the door, which took 15 seconds to ‘a couple minutes,’ and walked his coworkers
to their cars, which took 35 to 45 seconds. On rare occasions—once every couple
of months—Plaintiff spent a few minutes letting coworkers back inside the store
or bringing in patio furniture that he forgot to retrieve before clocking out.”
       Over the 17-month period of his employment, Troester’s unpaid time
totaled approximately 12 hours and 50 minutes. At the then-applicable minimum
wage of $8 per hour, this unpaid time added up to $102.67, exclusive of any
penalties or other remedies. The district court further assumed that the additional
time would be administratively difficult to capture. Finally, while acknowledging
that Troester’s store closing activities were regularly occurring, the district court

                                           3
found that regularity not significant to its conclusion that the uncompensated time
was de minimis. The district court concluded that the de minimis doctrine applied
and granted summary judgment against Troester on his claim for unpaid wages as
well as his derivative claims for failure to provide accurate written wage
statements, failure to pay all final wages in a timely manner, and unfair
competition.
       On appeal, the Ninth Circuit recognized that although the de minimis
doctrine has long been a part of the FLSA, this court has never addressed whether
the doctrine applies to wage claims brought under California law. The court
further recognized that in some instances California law has been interpreted to be
more protective of employee wage claims than federal law. Against this
background, the Ninth Circuit certified the question presented to this court.
                                         II.
       In Anderson v. Mt. Clemens Pottery Co. (1946) 328 U.S. 680 (Anderson),
the high court considered whether certain types of employee activity constituted
compensable work time. The worksite was a pottery plant covering eight acres,
and the principal question was whether the employees should be compensated for
the time spent walking to and from their workstations and engaging in certain
preliminary and postliminary activities. The court held that generally such time is
compensable: “Since the statutory workweek includes all time during which an
employee is necessarily required to be on the employer’s premises, on duty or at a
prescribed workplace, the time spent in these activities must be accorded
appropriate compensation.” (Id. at pp. 690–691.) The court further held that once
an employee proves damages from an employer’s failure to pay for compensable
work, the fact that the precise amount of the damages is difficult to prove because
of the employer’s inadequate recordkeeping cannot be counted against the
employee: “[T]he employee has proved that he has performed work and has not

                                         4
been paid in accordance with the statute. The damage is therefore certain. The
uncertainty lies only in the amount of damages arising from the statutory violation
by the employer. In such a case ‘it would be a perversion of fundamental
principles of justice to deny all relief to the injured person, and thereby relieve the
wrongdoer from making any amend for his acts.’ ” (Id. at p. 688.)
       But Anderson qualified these holdings with a caveat: “We do not, of
course, preclude the application of a de minimis rule where the minimum walking
time is such as to be negligible. The workweek contemplated by § 7(a) [of the
FLSA] must be computed in light of the realities of the industrial world. When the
matter in issue concerns only a few seconds or minutes of work beyond the
scheduled working hours, such trifles may be disregarded. Split-second
absurdities are not justified by the actualities of working conditions or by the
policy of the Fair Labor Standards Act. It is only when an employee is required to
give up a substantial measure of his time and effort that compensable working
time is involved. The de minimis rule can doubtless be applied to much of the
walking time involved in this case, but the precise scope of that application can be
determined only after the trier of facts makes more definite findings as to the
amount of walking time in issue.” (Anderson, supra, 328 U.S. at p. 692.) The
court remanded for application of the de minimis doctrine to determine whether
the employee time spent on preliminary activities was “insubstantial and
insignificant” and “need not be included in the statutory workweek.” (Id. at
p. 693.)
       In 1961, the de minimis doctrine was codified as a federal regulation with a
proviso that the doctrine was to be applied sparingly and not arbitrarily: “In
recording working time under the FLSA, insubstantial or insignificant periods of
time beyond the scheduled working hours, which cannot as a practical
administrative matter be precisely recorded for payroll purposes, may be

                                           5
disregarded. The courts have held that such trifles are de minimis. (Anderson v.
Mt. Clemens Pottery Co., 328 U.S. 680 (1946).) This rule applies only where
there are uncertain and indefinite periods of time involved of a few seconds or
minutes duration, and where the failure to count such time is due to considerations
justified by industrial realities. An employer may not arbitrarily fail to count as
hours worked any part, however small, of the employee’s fixed or regular working
time or practically ascertainable period of time he is regularly required to spend on
duties assigned to him. See Glenn L. Martin Nebraska Co. v. Culkin, 197 F. 2d
981, 987 (C.A. 8, 1952), cert. denied, 344 U.S. 866 (1952), rehearing denied, 344
U.S. 888 (1952), holding that working time amounting to $1 of additional
compensation a week is ‘not a trivial matter to a workingman,’ and was not de
minimis; Addison v. Huron Stevedoring Corp., 204 F. 2d 88, 95 (C.A. 2, 1953),
cert. denied 346 U.S. 877, holding that ‘To disregard workweeks for which less
than a dollar is due will produce capricious and unfair results.’ Hawkins v. E. I. du
Pont de Nemours & Co., 12 W.H. Cases 448, 27 Labor Cases, para. 69,094 (E.D.
Va. 1955), holding that 10 minutes a day is not de minimis.” (29 C.F.R. § 785.47
(2018).)
       Subsequently, the Ninth Circuit in Lindow v. U.S. (9th Cir. 1984) 738 F.2d
1057 (Lindow) explained that “in determining whether otherwise compensable
time is de minimis [under the FLSA], we will consider (1) the practical
administrative difficulty of recording the additional time; (2) the aggregate amount
of compensable time; and (3) the regularity of the additional work.” (Id. at
p. 1063.) This test has been widely used by federal courts. (See, e.g, Kellar v.
Summit Seating Inc. (7th Cir. 2011) 664 F.3d 169, 176; Carlsen v. United States.
(Fed.Cir. 2008) 521 F.3d 1371, 1380–1381; De Asencio v. Tyson Foods, Inc. (3d
Cir. 2007) 500 F.3d 361, 374–375; Brock v. City of Cincinnati (6th Cir. 2001) 236

                                          6
F.3d 793, 804–805; Kosakow v. New Rochelle Radiology Assocs., P.C. (2d Cir.
2001) 274 F.3d 706, 719; Metzler v. IBP, Inc. (10th Cir. 1997) 127 F.3d 959, 965.)
       Lindow noted that “[m]ost courts have found daily periods of
approximately 10 minutes de minimis even though otherwise compensable.”
(Lindow, supra, 738 F.2d at p. 1062 [collecting cases].) But Lindow recognized
that “[n]o rigid rule can be applied with mathematical certainty.” (Ibid.) Lindow
also observed that courts should consider “the size of the aggregate claim. Courts
have granted relief for claims that might have been minimal on a daily basis but,
when aggregated, amounted to a substantial claim. [Citations.] We would
promote capricious and unfair results, for example, by compensating one worker
$50 for one week’s work while denying the same relief to another worker who has
earned $1 a week for 50 weeks.” (Id. at p. 1063.)
       In order to determine whether the federal de minimis doctrine applies in
California wage litigation, we first examine the governing statutes and regulations.
In California, “wage and hour claims are today governed by two complementary
and occasionally overlapping sources of authority: the provisions of the Labor
Code, enacted by the Legislature, and a series of 18 wage orders, adopted by the
IWC.” (Brinker Restaurant Corp. v. Superior Court (2012) 53 Cal.4th 1004, 1026
(Brinker).) “The IWC’s wage orders are to be accorded the same dignity as
statutes. They are ‘presumptively valid’ legislative regulations of the employment
relationship [citation], regulations that must be given ‘independent effect’ separate
and apart from any statutory enactments.” (Id. at p. 1027.) Wage orders take
precedence over the common law to the extent they conflict. (See Martinez v.
Combs (2010) 49 Cal.4th 35, 64–65.)
       “When construing the Labor Code and wage orders, we adopt the
construction that best gives effect to the purpose of the Legislature and the IWC.
[Citations.] Time and again, we have characterized that purpose as the protection

                                          7
of employees — particularly given the extent of legislative concern about working
conditions, wages, and hours when the Legislature enacted key portions of the
Labor Code. [Citations.] In furtherance of that purpose, we liberally construe the
Labor Code and wage orders to favor the protection of employees. [Citations.]”
(Augustus v. ABM Security Services, Inc. (2016) 2 Cal.5th 257, 262 (ABM
Security).)
       “Federal regulations provide a level of employee protection that a state may
not derogate. Nevertheless, California is free to offer greater protection. We have
stated that, ‘[a]bsent convincing evidence of the IWC’s intent to adopt the federal
standard for determining whether time . . . is compensable under state law, we
decline to import any federal standard, which expressly eliminates substantial
protections to employees, by implication.’ [Citation.] More recently, we have
‘cautioned against “confounding federal and state labor law” [citation] and
explained “that where the language or intent of state and federal labor laws
substantially differ, reliance on federal regulations or interpretations to construe
state regulations is misplaced.” ’ ” (Mendiola v. CPS Security Solutions, Inc.
(2015) 60 Cal.4th 833, 843 (Mendiola).) On a number of occasions, we have
recognized the divergence between IWC wage orders and federal law, generally
finding state law more protective than federal law. (See ibid. [departing from
federal law in requiring compensation for sleep and other personal activities for
on-call employees residing on employer’s premises for extended period]; Martinez
v. Combs, supra, 49 Cal.4th at pp. 67–68 [noting the divergence between state and
federal definitions of “employ”]; Morillion v. Royal Packing Co. (2000) 22
Cal.4th 575, 588–592 (Morillion) [state law has not adopted a rule comparable to
federal Portal-to-Portal Act excluding certain transportation time under employer’s
control]; Ramirez v. Yosemite Water Co. (1999) 20 Cal.4th 785, 795–799

                                           8
[recognizing that the IWC’s definition of “outside salesperson” exempt from
overtime rules differs from federal definition].)
       In order to determine whether California has adopted the federal de minimis
rules, we first observe that IWC wage order No. 5-2001 (Wage Order No. 5)
concerning the “public housekeeping industry” includes establishments such as
Starbucks that provide food and beverages. (See Wage Order No. 5, subd. 2(P).)
Subdivision 2(K) defines hours worked as “the time during which an employee is
subject to the control of an employer, and includes all the time the employee is
suffered or permitted to work, whether or not required to do so . . . .” As case law
has clarified, the time during which “ ‘the employee is suffered or permitted to
work’ ” encompasses the time during which the employer knew or should have
known that the employee was working on its behalf. (Morillion, supra, 22 Cal.4th
at p. 585.) Subdivision 4(A) of Wage Order No. 5 sets the minimum wage and
specifies that wages must at least be paid to an employee “for all hours worked.”
Under subdivision (3)(A), employees covered by the wage order are entitled to
receive one and one-half times their regular rate of pay “for all hours worked” in
excess of eight hours in a workday or 40 hours in any workweek.
       The Labor Code also contemplates that employees will be paid for all work
performed. (All statutory references are to the Labor Code unless otherwise
indicated.) Section 510, subdivision (a) provides: “Eight hours of labor
constitutes a day’s work. Any work in excess of eight hours in one workday and
any work in excess of 40 hours in any one workweek and the first eight hours
worked on the seventh day of work in any one workweek shall be compensated at
the rate of no less than one and one-half times the regular rate of pay for an
employee. Any work in excess of 12 hours in one day shall be compensated at the
rate of no less than twice the regular rate of pay for an employee. In addition, any
work in excess of eight hours on any seventh day of a workweek shall be

                                          9
compensated at the rate of no less than twice the regular rate of pay of an
employee.” The section recognizes certain exceptions in various statutorily
authorized alternative workweeks, but no others.
       The federal rule permitting employers under some circumstances to require
employees to work as much as 10 minutes a day without compensation is less
protective than a rule that an employee must be paid for “all hours worked” (Wage
Order No. 5, subds. 3(A), 4(A)) or “[a]ny work” beyond eight hours a day (Lab.
Code, § 510, subd. (a)). And there is no “ ‘convincing evidence of the IWC’s
intent to adopt the federal standard.’ ” (Mendiola, supra, 60 Cal.4th at p. 843.)
Nothing in the language of the wage orders or Labor Code shows an intent to
incorporate the federal de minimis rule articulated in Anderson, Lindow, or the
federal regulation. Although Anderson has been the law for 70 years and has been
incorporated into the Code of Federal Regulations for over 50 years, neither the
Labor Code statutes nor any wage order has been amended to recognize a de
minimis exception. Starbucks cites no statutory or regulatory history, and we have
found none, that indicates an intent by the IWC or the Legislature to impliedly
adopt such a rule.
       Only one published Court of Appeal decision has applied the de minimis
rule in an employee compensation case, specifically using the Lindow factors.
(Gomez v. Lincare, Inc. (2009) 173 Cal.App.4th 508, 527–528.) But it did so
without considering whether the rule should apply to California wage claims, and
the court determined in any event that the rule did not apply in the case before it,
which involved several hours per week of uncompensated time. (Ibid.)
       We recognize that the de minimis doctrine appears in the Enforcement
Policies and Interpretations Manual published by the Division of Labor Standards
Enforcement (DLSE Manual). Sections 47.2.1 and 47.2.1.1 of the manual adopt
virtually verbatim the federal regulation on this issue. (DLSE Manual (2002

                                         10
update) p. 47–1; see 29 C.F.R. § 785.47 (2018).) But unlike wage orders, the
DLSE Manual is not binding on this court. (Mendiola, supra, 60 Cal.4th at
p. 848.) Although statements in the policy manual may be considered for their
persuasive value, the DLSE Manual contains rules that have not been subject to
the Administrative Procedures Act and do not represent an exercise of quasi-
legislative authority by an administrative agency. (See Alvarado v. Dart
Container Corp. of California (2018) 4 Cal.5th 542, 555–561; DLSE Manual at
pp. 1-1 to 1-2.)
       The DLSE has also issued opinion letters adopting the Lindow test for the
de minimis rule. (See Dept. of Industrial Relations, DLSE Opn. Letter
No. 1988.05.16 (1988).) Such advisory opinions are also not binding, although
they may be a source of informed judgment to which courts and litigants may
resort for guidance. (See Yamaha Corp. of America v. State Bd. of Equalization
(1998) 19 Cal.4th 1, 14.) Here, the DLSE’s adoption of the federal de minimus
rule appears to be based on the general proposition that federal case law
construing the FLSA “may sometimes provide guidance to state courts in
interpreting the IWC Orders.” (DLSE Opn. Letter No. 1988.05.16. at p. 1.) But
we will not presume the IWC intended to incorporate a less protective federal rule
without evidence of such intent, and we see no sign of such intent here.
                                        III.
       Our conclusion that California statutes and wage orders have not adopted
the federal de minimis doctrine does not fully resolve the issue before us.
According to Starbucks, the de minimis rule is also a principle of California law
that is independently applicable to wage and hour cases as a matter of state law.
Starbucks cites Wisconsin Dept. of Revenue v. William Wrigley, Jr., Co. (1992)
505 U.S. 214, which examined a federal statute granting immunity from state
taxation to companies when their only business contact with the state is the

                                         11
solicitation of orders. At issue was whether de minimis business contacts other
than solicitation of orders would forfeit this immunity under the statute. The high
court concluded that the de minimis principle applied, rejecting Wisconsin’s
argument that “the plain language of the statute bars this recognition of a de
minimis exception, because the immunity is limited to situations where ‘the only
business activities within [the] State’ are those described, 15 U.S.C. § 381
(emphasis added). This ignores the fact that the venerable maxim de minimis non
curat lex (‘the law cares not for trifles’) is part of the established background of
legal principles against which all enactments are adopted, and which all
enactments (absent contrary indication) are deemed to accept.” (Id. at p. 231.)
Starbucks argues that even if the relevant Labor Code statutes and wage order
have not explicitly adopted the federal de minimis rule, the de minimis principle is
part of the “established background of legal principles” against which the statutes
and wage order have been enacted.
       Troester contends that the fact that the IWC has not adopted an explicit de
minimis regulation after it had been incorporated into federal law is a sign that the
IWC intended to preclude its application in wage cases. Troester further contends
that unlike the California Labor Code, the text of the FLSA does not contain a
blanket requirement to pay employees for all hours worked, except in a regulation
that postdated and implicitly incorporated Anderson’s de minimis rule. (29 C.F.R.
§ 778.223 (2018).)
       We have recognized that the maxim de minimis non curat lex is “of ancient
origin” and may be incorporated by implication into the state’s statutory and
constitutional enactments. (Gerawan Farming, Inc. v. Lyons (2000) 24 Cal.4th
468, 514 [recognizing the incorporation of that principle into the free speech
clause of the California Constitution].) This principle is among the maxims of
jurisprudence codified in the California Civil Code. (Civ. Code, § 3533 [“The law

                                          12
disregards trifles.”].) The rule originated as one of the maxims of equity
formulated by English Courts of Chancery. (See Nemerofsky, What Is a “Trifle”
Anyway? (2001–2002) 37 Gonz. L.Rev. 315, 322–323.) “The function of the ‘de
minimis’ doctrine . . . is to place ‘outside the scope of legal relief the sorts of
intangible injuries, normally small and invariably difficult to measure, that must
be accepted as the price of living in society.’ The maxim signifies ‘that mere
trifles and technicalities must yield to practical common sense and substantial
justice’ so as ‘to prevent expensive and mischievous litigation, which can result in
no real benefit to complainant, but which may occasion delay and injury to other
suitors.’ ” (Id. at pp. 323–324, fns. omitted.) Starbucks argues that in light of the
“ancient roots” of the de minimis rule, we should recognize it as part of our wage
and hour law, just as Anderson recognized the rule as applicable to the FLSA
despite no explicit statutory basis.
       We decline to decide whether a de minimis principle may ever apply to
wage and hour claims given the wide range of scenarios in which this issue arises.
In FLSA litigation, the brief employee activity in question has sometimes been
incidental to noncompensable time, such as commute time. (See Chambers v.
Sears Roebuck & Co. (S.D.Tex. 2011) 793 F.Supp.2d 938, 960; Andrews v.
Dubois (D.Mass. 1995) 888 F.Supp. 213, 219; Singh v. City of New York (2d Cir.
2008) 524 F.3d 361.) In other cases, the activity in question was irregular or
rarely occurring. (Musticchi v. City of Little Rock (E.D.Ark. 2010) 734 F.Supp.2d
621, 633.) In still others, the activity in question was paperwork involving a
minute or less of an employee’s time. (Rutti v. Lojack Corp. (9th Cir. 2010) 596
F.3d 1046, 1057–1058.) Beyond the cases, briefs on behalf of Starbucks invoke
various hypothetical scenarios of de minimis activity, such as an employee reading
an e-mail notification of a shift change during off-work hours.

                                           13
       Instead of prejudging these factual permutations, we decide only whether
the de minimis rule is applicable to the facts of this case as described by the Ninth
Circuit. As noted, Troester had various duties related to closing the store after he
clocked out, and the parties agree for purposes of resolving the issue before us that
the time spent on these duties is compensable. According to the Ninth Circuit,
“[t]he undisputed evidence was that, on a daily basis, these closing tasks generally
took [Troester] about 4-10 minutes . . . . [The district court] further assumed that
the additional time would be administratively difficult to capture.” (This time is in
addition to the time Troester alleges he spent “once every couple months” letting
coworkers back inside the store or bringing in patio furniture that he forgot to
retrieve before clocking out, time that Starbucks contends was not compensable.)
       The de minimis rule, as a background principle, has been invoked in a
variety of statutory contexts, and courts have decided such cases by examining
whether application of the rule would be consistent with the statutory purpose.
(See Goehring v. Chapman University (2004) 121 Cal.App.4th 353, 384
[“Substantial compliance with a statute ‘will suffice if the purpose of the statute is
satisfied . . . but substantial compliance means actual compliance in respect to that
statutory purpose.’ ”].) In the employment context, we have held that there is no
de minimis exception to the assessment of penalties for unreasonable delay in the
payment of workers compensation payments: “The language of section 5814 . . .
does not recognize any such exception and requires assessment of the penalty for
any ‘unreasonable’ delay . . . .” (Gallamore v. Workers’ Comp. Appeals Bd.
(1979) 23 Cal.3d 815, 822.) In Amaral v. Cintas Corp. No. 2 (2008) 163
Cal.App.4th 1157, 1191, the court declined to read into a municipal living wage
ordinance an exception for workers who performed only a small amount of work
on city contracts. In interpreting the unemployment insurance statutes, courts
have construed them to contain a de minimis exception when that construction was

                                          14
consistent with the statutes’ purpose of cushioning the impact of involuntary
unemployment (see Cooperman v. Unemployment Ins. Appeals Bd. (1975) 49
Cal.App.3d 1, 10 [finding that despite de minimis services rendered by applicant,
he was “unemployed” per section 1252 of the Unemployment Insurance Code])
while declining to find such an exception when it would run counter to that
protective purpose (see Jaffe v. Unemployment Ins. Appeals Bd. (1984) 156
Cal.App.3d 719, 725 [refusing to invoke a de minimis rule where unemployment
benefits would have been temporarily interrupted]).
       We have said that application of a de minimis rule is inappropriate when
“the law under which this action is prosecuted does care for small things.”
(Francais v. Somps (1891) 92 Cal. 503, 506.) In deciding whether application of
the de minimis rule in this case would be consistent with the governing wage order
and Labor Code statutes, we observe that the regulatory scheme of which the
relevant statutes and wage order provisions are a part is indeed concerned with
“small things.” For example, California law ensures that most nonexempt
employees receive two daily 10-minute rest breaks. (Wage Order No. 5,
subd. (12)(A); see Brinker, supra, 53 Cal.4th at p. 1031.) We have interpreted
Wage Order No. 5 as requiring strict adherence to that requirement, and we have
scrupulously guarded against encroachments on this 10-minute period. Thus, we
recently held that the obligation to relieve employees of any work-related duties
during the rest period barred employers from requiring employees to be on call
during their rest breaks and that breach of this duty triggers an employer’s
obligation under section 226.7, subdivision (b) to pay the employee an additional
hour of pay. (ABM Security, supra, 2 Cal.5th at p. 265.)
       ABM Security, though addressing a different issue, is instructive in two
respects. First, although the de minimis principle was not explicitly invoked, we
implicitly rejected the argument that a de minimis intrusion into a 10-minute rest

                                         15
period would pass muster under the statute. Second, the strict construction of a
law prohibiting any interference with or reduction of a 10-minute rest break is
difficult to reconcile with a rule that would regard a few minutes of compensable
time per day as a trifle not requiring compensation if too inconvenient to record.
       Although the IWC has not specifically addressed the de minimis rule, we
note that its regulations have been more expansive than the FLSA in defining the
time for which an employee must be compensated. Most closely on point is the
IWC’s response to the federal Portal-to-Portal Act (29 U.S.C. § 251 et seq.). This
legislation was a 1947 amendment to the FLSA relieving “employers from paying
minimum wages or overtime compensation to employees for the following
activities: ‘(1) walking, riding, or traveling to and from the actual place of
performance of the principal activity or activities which such employee is
employed to perform, and (2) activities which are preliminary to or postliminary to
said principal activity or activities . . . .’ ” (Morillion, supra, 22 Cal.4th at p. 589.)
The amendment was “partly in response to [Congress’s] concern that the FLSA
‘has been interpreted judicially in disregard of long-established customs, practices,
and contracts between employers and employees . . . .’ ” (Id. at p. 590, quoting 29
U.S.C. § 251.) More specifically, the amendment was a response to Anderson’s
holding that the time walking to a workstation was compensable. (See Linder,
Class Struggle at the Door: The Origins of the Portal-to-Portal Act of 1947
(1991) 39 Buff. L.Rev. 53, 106–130.) At the same time, the IWC amended its
definition of “hours worked” in its wage orders, eliminating reference to specific
preliminary or postliminary activities such as “waiting time,” while broadening the
definition to include “ ‘the time during which an employee is subject to the control
of an employer.’ ” (Morillion, at p. 591.) We concluded that this amended
language was evidence of an intent to depart from the federal exclusion of various
forms of travel time in the Portal-to-Portal Act. (Id. at pp. 591–592.)

                                           16
       Although the IWC amendment, which postdated Anderson by one year, did
not specifically address the de minimis doctrine, we find it instructive that the
amended wage order broadly defined “hours worked” to include preliminary and
postliminary activities excluded by the FLSA. It is also instructive that the IWC
in defining “hours worked” appeared to give little weight to the customary
employment practices that informed Congress’s decision to enact the Portal-to-
Portal Act and instead placed more importance on the policy of ensuring that
employees are fully compensated for all time spent in the employer’s control.
       Moreover, although FLSA case law can be persuasive authority in
interpreting our own wage laws, the reasoning of Anderson is questionable. We
do not hold that payment for time worked must account for “[s]plit-second
absurdities.” (Anderson, supra, 328 U.S. at p. 692.) But it is not clear that
“[s]plit-second absurdities” can be readily equated with “minutes of work beyond
the scheduled working hours” or that an action should be permitted only when “an
employee is required to give up a substantial measure of his time and effort.”
(Ibid.) Nor is it clear why, when it is difficult to keep track of time worked, the
employee alone should bear the burden of that difficulty.
       Two additional considerations reinforce our reluctance to fully adopt
Anderson’s reasoning as a matter of state law. First, the modern availability of
class action lawsuits undermines to some extent the rationale behind a de minimis
rule with respect to wage and hour actions. The very premise of such suits is that
small individual recoveries worthy of neither the plaintiff’s nor the court’s time
can be aggregated to vindicate an important public policy. As we explained in
Linder v. Thrifty Oil Co. (2000) 23 Cal.4th 429, a class action suit involving a
4 cents per gallon surcharge on gasoline customers using credit cards: “Setting
aside the fact that class members who were repeat customers might be entitled to
recover far more than the minimal 80-cent damage figure noted by the trial court,

                                          17
it is firmly established that the benefits of certification are not measured by
reference to individual recoveries alone. Not only do class actions offer
consumers a means of recovery for modest individual damages, but such actions
often produce ‘several salutary by-products, including a therapeutic effect upon
those sellers who indulge in fraudulent practices, aid to legitimate business
enterprises by curtailing illegitimate competition, and avoidance to the judicial
process of the burden of multiple litigation involving identical claims.’ ” (Id. at
p. 445.) As one Court of Appeal observed in a case involving alleged fraudulent
practices against consumers, “[i]n this age of the consumer class action this maxim
[de minimis non curat lex] usually has little value.” (Harris v. Time, Inc. (1987)
191 Cal.App.3d 449, 458.) The same is true of employee class actions.
       Second, many of the problems in recording employee work time discussed
in Anderson 70 years ago, when time was often kept by punching a clock, may be
cured or ameliorated by technological advances that enable employees to track and
register their work time via smartphones, tablets, or other devices. We are
reluctant to adopt a rule purportedly grounded in “the realities of the industrial
world” (Anderson, supra, 328 U.S. at p. 692) when those realities have been
materially altered in subsequent decades.
       Both Troester and Starbucks cite See’s Candy Shops, Inc. v. Superior Court
(2012) 210 Cal.App.4th 889 (See’s Candy) in support of their positions. The main
issue in that case was the employer’s practice of rounding the time employees
punched in or out of work. As the court explained: “Under the nearest-tenth
rounding policy, in and out punches are rounded (up or down) to the nearest tenth
of an hour (every six minutes beginning with the hour mark). The Kronos time
punches are thus rounded to the nearest three-minute mark. For example, if an
employee clocks in at 7:58 a.m., the system rounds up the time to 8:00 a.m. If the
employee clocks in at 8:02 a.m., the system rounds down the entry to 8:00 a.m.”

                                          18
(Id. at p. 892.) The court noted that although there were no reported California
decisions on the issue, such rounding policy had long been used by employers and
had been recognized as legitimate under federal regulation and the DLSE Manual.
(Id. at pp. 901–903.) The court rejected the argument that California wage or
overtime statutes prohibit such a practice. (Id. at pp. 905–907.)
       Significantly, the court in See’s Candy, consistent with federal law and
DLSE directive, accepted the validity of the rounding policy only “if the rounding
policy is fair and neutral on its face and ‘it is used in such a manner that it will not
result, over a period of time, in failure to compensate the employees properly for
all the time they have actually worked.’ ” (See’s Candy, supra, 210 Cal.App.4th
at p. 907.) On this basis, the court held there was a triable issue as to whether the
company’s rounding policy “was proper under California law because it was used
in a manner that did not result over a period of time in the failure to compensate
the employees for all the time they actually worked.” (Id. at p. 908.)
       In support of its position, Starbucks cites See’s Candy’s reliance on federal
law and the DLSE Manual, and its rejection of arguments similar to Troester’s
contention that the policy is barred by statutes requiring payment to the employer
of all wages. But critically, See’s Candy rested its holding on its determination
that the rounding policy was consistent with the core statutory and regulatory
purpose that employees be paid for all time worked. Starbucks argues for a
departure from that principle, and we conclude no such departure is warranted in
this case.
       In light of the Wage Order’s remedial purpose requiring a liberal
construction, its directive to compensate employees for all time worked, the
evident priority it accorded that mandate notwithstanding customary employment
arrangements, and its concern with small amounts of time, we conclude that the de
minimis doctrine has no application under the circumstances presented here. An

                                           19
employer that requires its employees to work minutes off the clock on a regular
basis or as a regular feature of the job may not evade the obligation to compensate
the employee for that time by invoking the de minimis doctrine. As the facts here
demonstrate, a few extra minutes of work each day can add up. According to the
Ninth Circuit, Troester is seeking payment for 12 hours and 50 minutes of
compensable work over a 17-month period, which amounts to $102.67 at a wage
of $8 per hour. That is enough to pay a utility bill, buy a week of groceries, or
cover a month of bus fares. What Starbucks calls “de minimis” is not de minimis
at all to many ordinary people who work for hourly wages.
       We recognize that one of the main impetuses behind the de minimis
doctrine in wage cases is “the practical administrative difficulty of recording small
amounts of time for payroll purposes.” (Lindow, supra, 738 F.2d at p. 1062; see
29 C.F.R. § 785.47 (2018) [insignificant periods of time “which cannot as a
practical administrative matter be precisely recorded for payroll purposes, may be
disregarded”].) But employers are in a better position than employees to devise
alternatives that would permit the tracking of small amounts of regularly occurring
work time. One such alternative, which it appears Starbucks eventually resorted to
here, was to restructure the work so that employees would not have to work before
or after clocking out. Moreover, as noted, technological advances may help with
tracking small amounts of time. An employer may be able to customize and adapt
available time tracking tools or develop new ones when no off-the-shelf product
meets its needs. And even when neither a restructuring of work nor a
technological fix is practical, it may be possible to reasonably estimate work time
— for example, through surveys, time studies, or, as See’s Candy suggested, a fair
rounding policy — and to compensate employees for that time. Under the
circumstances of this case, we decline to adopt a rule that would require the

                                         20
employee to bear the entire burden of any difficulty in recording regularly
occurring work time.
                                   CONCLUSION
       We hold that the relevant California statutes and wage order have not
incorporated the de minimis doctrine found in the FLSA. We further conclude
that although California has a de minimis rule that is a background principle of
state law, the rule is not applicable here. The relevant statutes and wage order do
not allow employers to require employees to routinely work for minutes off-the-
clock without compensation. We leave open whether there are wage claims
involving employee activities that are so irregular or brief in duration that it would
not be reasonable to require employers to compensate employees for the time
spent on them.

                 CONCURRING OPINION BY CUÉLLAR, J.
       Today’s majority opinion is right to conclude that no de minimis doctrine
exists under California law to insulate an employer from responsibility for paying
an employee who regularly works for minutes off the clock. But in reaching this
conclusion, the majority opinion also leaves unresolved whether an employee’s
work may ever be so fleeting or irregular that such time is no longer compensable.
I write separately to emphasize that our opinion today is both principled and
practical: It protects workers from being denied compensation for minutes they
regularly spend on work-related tasks, but does not consign employers or their
workers to measure every last morsel of employees’ time. The latter point is as
important as the former, because advances in technology and changes in
behavioral norms are constantly shaping our understanding of what fractions of
time can be reliably measured, and what counts as too trifling a moment to
measure in the wage and hour context. While there is no de minimis rule that
applies to this domain of California law — at least where minutes of regular off-
the-clock time are at issue — there is room for a rule of reason to avoid a situation
forcing employers to monitor every fraction of every second of employee time.
But what we must avoid in addressing these concerns — and in construing
the body of law the majority opinion interprets today — is building a rickety
skyscraper on a muddy swamp by relying on an administrability rationale
too precarious to offer much meaningful analytical structure to a rule of reason,
given the evolving technological fabric of modern life.
       Modern technology allows society not only to measure time, but — ever
more — to master the knowledge of precisely how it is used, by whom, and for
what purpose. In federal case law, the de minimis doctrine is grounded in the
practical administrative difficulties of tracking time that amounts to “split-second
absurdities.” (Anderson v. Mt. Clemens Pottery Co. (1946) 328 U.S. 680, 692
(Anderson).) Change the technology available to employers and the public’s
acceptance of broad surveillance, and the result is a shift in the norm governing
what’s “practical.” The majority opinion rightly observes that computer and
smartphone technologies undercut any rationale for a de minimis doctrine that
would find minutes of work performed on a regular basis to not be compensable.
(Maj. opn., ante, at p. 20.) More generally, the majority indicates that
“technological advances” may increasingly facilitate tracking small amounts of
regularly occurring work time. (Ibid.)
       Yet when it comes to monitoring the minutia of human behavior, the future
and the present are converging. In a world with pervasively deployable (or
already deployed) locative technology such as smartphones and sensors, what
employers can routinely record — or will soon be able to — are precisely the
“split-second absurdities” previously deemed impossible to track. (See Tippett et
al., When Timekeeping Software Undermines Compliance (2017) 19 Yale J.L. &
Tech. 1, 2–3 [“In place of the old punch-card time clock, employees now log onto
a computer or mobile device, swipe a radio frequency identification (RFID) badge,
scan a fingerprint, or gaze into an iris recognition device. These and similar
systems enable employers easily to record employees’ hours worked, breaks taken,
and other information used to determine compensation.” (fn. omitted)].) Even as
such practices can help employers ensure their workers are compensated for
regularly worked minutes that might have once been treated as “off the clock,”
they also highlight the need for subsequent line drawing to implement existing

                                          2
law. Without some appropriate limiting principle, one can imagine a lawsuit
based on regularly occurring or even occasional additional work time that amounts
to less than a second. Depending on the industry, employers may have difficulty
arguing, as a matter of administrability, that they cannot either categorically
exclude from employees’ responsibility any time employers cannot measure, or
deploy increasingly familiar technologies to measure such narrow slices of time
with some accuracy.
       In the absence of a legislatively drawn bright line, making sense of the
resulting questions may work best, as Justice Kruger suggests in her concurring
opinion, if we apply some “rule of reason” for determining which of these claims
are sufficient to bring a wage and hour suit. (Conc. opn. of Kruger, J., post, at p.
2.) The rule of reason is best not described as a de minimis rule, because
embracing that label risks blurring the distinction between the quite limited extent
of the reasonableness inquiry under California law and a federal de minimis
doctrine with a particular content — including reliance on administrability — that
does not necessarily converge with California’s legal commitments. Those
commitments protect workers from being forced to engage in uncompensated
work even as they also offer some recognition that certain spare seconds or
fractions of them spent on arguably work-related activities may not always merit
compensation. (See Civ. Code, § 3533 [“The law disregards trifles”]; Gerawan
Farming, Inc. v. Lyons (2000) 24 Cal.4th 468, 514 [“De minimis non curat lex is a
maxim of ancient origin, ‘old’ even in the infancy of the nation”]; Layport v.
Rieder (1939) 37 Cal.App.2d Supp. 742, 748, disapproved on other grounds in
Heald v. Friis-Hansen (1959) 52 Cal.2d 834 [finding 8-cent difference in
calculation of accrued interest to be “too trifling to be considered as grounds for
requiring a trial”].) Still, once claimed time is established as compensable, the
onus is on the employer to demonstrate that “reason” requires the employee to go

                                          3
uncompensated for the time she worked given California’s strong policy favoring
compensation. (See Industrial Welfare Com., Wage Order No. 5-2001 (Jan. 1,
2001), Cal. Code Regs., tit. 8, § 11050, subd. 4(A) (hereafter Wage Order 5)
[“Every employer shall pay to each employee wages . . . for all hours
worked . . . .”].) The difficulty is discerning on what basis an agency or a judge’s
“reason” might serve to limit the overarching policy incorporated into California
law of fully compensating employees for the work they perform, with no stable
technological impossibility on this front as a convenient way to settle whether to
track even “split seconds.”
       What reasonableness in this domain almost certainly implicates is whether
such chronological morsels can be meaningfully perceived at all at the time they
occur. That people sometimes struggle to perceive distinctions involving fractions
of a second is inherent in human limitations. Modern computer displays, for
example, generally refresh their screen at a rate of 60 hertz (each cycle lasting
approximately 0.0167 seconds) because humans generally will no longer see a
“flicker” on the screen at such a rate. (But see Davis et al., Humans perceive
flicker artifacts at 500 Hz (2015) Scientific Reports 5, art. No. 7861, at p. 1
 [as of July 24, 2018]1
[indicating that, previous to this study indicating that humans could perceive
flicker at 500 hertz, it was thought that humans could not perceive flicker above
50 to 90 hertz, depending on the intensity and contrast of the picture].) In terms of
reaction time, at least one study reveals the average reaction time of medical
students to visual stimuli was approximately 0.25 seconds. (Jain et al., A
comparative study of visual and auditory reaction times on the basis of gender and
physical activity levels of medical first year students (2015) 5 Int’l J. Applied

1     All Internet citations in this opinion are archived by year, docket number,

                                          4
Basic Medical Research 124-127  [as of July 24, 2018]; see also id. [also referencing to 0.19 seconds
as the “accepted” mean reaction time to light for college age students].) It seems
unlikely the Legislature’s purpose in enacting California’s fair compensation laws
encompassed compensation of employees for additional work performed on such a
time scale. (See Wisconsin Dept. of Revenue v. William Wrigley, Jr., Co. (1992)
505 U.S. 214, 231 [noting that “ ‘the law cares not for trifles’ ” is “part of the
established background of legal principles against which all enactments are
adopted, and which all enactments (absent contrary indication) are deemed to
accept”].) It is far from clear that a reasonable rounding strategy, even one
rounding to the nearest second, would cut in favor of counting such amounts of
time. (Cf. See’s Candy Shops, Inc. v. Superior Court (2012) 210 Cal.App.4th 889,
892 [rounding time to nearest six minutes].) Were such a rounding rule justified,
it would leave the potential problem in class actions of allocating awards to
claimants based on fractional cents. As a countervailing concern, a minute or even
dozens of seconds may seem trifling to an employer even if — as the majority
opinion points out — these small moments appreciably impact employees at the
time.
        In the realm of time people can ordinarily perceive, any sensible evaluation
will likely depend largely on the context in which the work at issue occurs, along
with considerations rooted in privacy law or collective bargaining agreements.
(See, e.g., Hernandez v. Hillsides, Inc. (2009) 47 Cal.4th 272, 286-288 [discussing
employees’ right to privacy under the Cal. Const. and the common law];
Carpenter v. U.S. (2018) 585 U.S. __, __ [138 S.Ct. 2206, 2210] [recognizing a
4th Amend. reasonable expectation of privacy in “the whole of [a person’s]
physical movements”]; 18 U.S.C. §§ 2510 et seq., 2701 et seq. [providing
protections implemented by the federal Electronic Communications Privacy Act of

                                           5
1986 that limit the unauthorized interception and retrieval of electronic
communications, with some exceptions]; Lavitt, Monitoring Employee
Whereabouts: Collective Bargaining Implications of RFID and GPS Technologies
in the Workplace (Nov. 4, 2011) 5th Annual ABA Section of Labor &
Employment Law Conference, at pp. 11-13  [as of July 24, 2018] [discussing cases where collective bargaining
agreements addressed GPS and other employee tracking systems].) So we must be
wary of any future holding that would incentivize a drastic increase in the scope
and intensity of employee monitoring, which might systematically erode
employees’ ability to find even a moment of privacy in their lives. (Kesan, Cyber-
Working or Cyber-Shirking?: A First Principles Examination of Electronic
Privacy in the Workplace (2002) 54 Fla. L.Rev. 289, 320 [noting fears that
excessive monitoring of employees creates essentially “ ‘electronic
sweatshop[s]’ ”].) This is especially true as privacy issues have launched to the
national stage and resulted in new laws in our state safeguarding privacy in our
personal data, albeit in the consumer law context. (See Consumer Privacy Act of
2018, Civ. Code, § 1798.100 et seq. (added by Stats. 2018, ch. 55, § 3, eff. Jan. 1,
2020) [granting any consumer, defined as “a natural person who is a California
resident,” certain rights with respect to personal data collected by businesses].) At
the very least, our compensation rulings should not require subcutaneous
microchips, pervasive digital surveillance of all employees’ actions and
communications, or other employment monitoring systems more at home in a
cyberpunk novel than a modern place of employment. (See, e.g., Mo. Rev. Stat.,
§ 285.035(1) [“No employer shall require an employee to have personal
identification microchip technology implanted into an[] employee for any
reason”].)

                                          6
       The majority here does not reach such a troubling result. Instead it
observes that employers have the burden of tracking potential work time occurring
on a “regular basis” or that is “a regular feature of the job,” and in doing so,
rightly focuses on reasonable solutions such as smartphone apps or rounding
strategies for tracking these regular amounts of time. (Maj. opn., ante, at p. 20.)
The unpredictable length and occasional nature of the additional work at issue may
affect the viability of some timekeeping systems and rounding strategies —
though here too, other monitoring or data analysis approaches may often resolve
the difficulties.
       In addition to discussing the potential solutions an employer might adopt,
the majority’s opinion emphasizes how the work performed here was “regular” in
concluding that it was compensable. (Maj. opn., ante, at pp. 20-21.) The focus on
“regularity” is, to some extent, based on technological concerns — it seems more
practical to require an employer to track work time that is predictable. Yet
regularity also may act as a proxy for the principle that employees should always
be fully compensated for core or expected aspects of their work. The standard for
what is compensable work time in California is relatively broad and includes all
time for which the employer knew or should have known that the employee was
working on the employer’s behalf. (Morillion v. Royal Packing Co. (2000) 22
Cal.4th 575, 584-585 [interpreting wage order language that makes compensable
all time “ ‘the employee is suffered or permitted to work, whether or not required
to do so’ ”].) Concepts of fair dealing weigh against allowing an employer to
knowingly require an employee to perform a task, and then claim that said task
was “de minimis” after the fact. In contrast, there may be occasional activities
involving far less time than was at issue here, peripheral to the employee’s core
job function, and undertaken for reasons other than service to the employer.

       As easily available technologies can increasingly track our every movement
and moment, California law still protects workers from being forced to undertake
work that won’t be paid. That protection is not diluted if it remains possible for
employers to argue against liability for moments so fleeting that they are all but
imperceptible. Courts may sometimes find employers’ arguments to have merit in
light of a context-dependent inquiry focused on the extent to which the time in
question can be meaningfully perceived, the quantity and regularity of the
uncompensated work over time, as well as the nature of the employee’s job
responsibilities and related factors. What we know is that regular minutes worked
by employees off the clock do not come close to being treatable essentially as
rounding errors under a sensible application of a rule of reason. And issues of
employee privacy will no doubt be subject to further deliberation among
employers, employees, and legislators. Yet whatever the merits of sophisticated
employee monitoring schemes, California law stops well short of requiring
employer analysis of every fractional second as part of an unsparing effort to
discern what time is compensable.

                  CONCURRING OPINION BY KRUGER, J.

       I concur in the majority opinion, which I have signed. I write separately to
address the central question the opinion leaves open: whether, in circumstances
different from those presented in this case, the de minimis principle may apply to
California wage and hour claims. (See maj. opn., ante, at pp. 2, 13, 21.)
       As the majority opinion explains (ante, at pp. 12–13), the maxim de
minimis non curat lex represents a background legal principle of ancient standing.
The 1872 Legislature codified the maxim in our Civil Code (Civ. Code, § 3533),
and like other such maxims it serves as an interpretive tool to aid in the “just
application” of facially broad statutory language. (Id., § 3509; see National
Shooting Sports Foundation, Inc. v. State of California (2018) 5 Cal.5th 428, 433.)
One recognized function of the maxim is to avoid litigation over trivial harms,
where the costs of litigating the correct measure of a remedy may exceed the
benefits of providing the remedy in the first place. Simply put, “[t]he maxim
signifies ‘that mere trifles and technicalities must yield to practical common sense
and substantial justice . . . .’ ” (Nemerofsky, What Is a “Trifle” Anyway? (2001–
2002) 37 Gonz. L.Rev. 315, 323.) The de minimis doctrine operates, in essence,
as a “rule of reason.” (Veech & Moon, De Minimis Non Curat Lex (1947) 45
Mich. L.Rev. 537, 556, 567; see id. at pp. 543–544.)
       Here, we consider provisions of California labor law that mandate
compensation for “[a]ny” (Lab Code, § 510, subd. (a)) and “all” time worked

                                          1
(Industrial Welfare Com., Wage Order No. 5, subd. 2(K)). The breadth of the
language reflects California’s vital interest in ensuring that employers fully
compensate their employees for the work they perform. (See, e.g., Kerr’s
Catering Service v. Department of Industrial Relations (1962) 57 Cal.2d 319, 326
[citing California’s strong public policy “in favor of full and prompt payment of
wages due an employee”].) But the law, fairly construed, also leaves room for
application of a background rule of reason. A sensible application of our law does
not encompass claims for negligible periods of time that cannot reasonably be
measured or estimated with a fair degree of accuracy.
       The United States Supreme Court described this sort of a commonsense
limitation on wage claims when it held that “[s]plit-second absurdities” are to be
disregarded in calculating compensable working time. (Anderson v. Mt. Clemens
Pottery Co. (1946) 328 U.S. 680, 692.) Nothing in the majority opinion calls into
question whether California law observes the same basic limitation. (Maj. opn.,
ante, at p. 17.) The majority opinion instead correctly holds that insofar as the
federal de minimis doctrine has been applied more broadly to include individually
or cumulatively significant periods of time that can reasonably be measured or
estimated, the federal doctrine does not represent the law of California. (Id. at
pp. 8–11.) As the majority says, “[a]n employer that requires its employees to
work minutes off the clock on a regular basis or as a regular feature of the job may
not evade the obligation to compensate the employee for that time by invoking the
de minimis doctrine.” (Id. at pp. 19–20.)
       To say that the de minimis doctrine cannot excuse failing to compensate
employees under these circumstances is not to say that the de minimis doctrine has
no role to play under any circumstance; a properly limited rule of reason does have
a place in California labor law. The overarching rule is, and must be, that
employees are entitled to full compensation for time worked, and employers must

                                          2
make every reasonable effort to ensure they have adequately measured or
estimated that time. But the law also recognizes that there may be some periods of
time that are so brief, irregular of occurrence, or difficult to accurately measure or
estimate, that it would neither be reasonable to require the employer to account for
them nor sensible to devote judicial resources to litigating over them.
       The claim here involves nontrivial, regularly occurring periods of work,
and thus is not subject to any such properly limited de minimis rule. And I agree
with the majority that without an appropriate factual record before us, this is not
the case for detailed delineation of the rule’s proper scope. But it is not difficult to
imagine a number of scenarios in which such a rule might apply, depending on the
circumstances:
            An employer requires workers to turn on their computers and log in
              to an application in order to start their shifts. Ordinarily this process
              takes employees no more than a minute (and often far less,
              depending on the employee’s typing speed), but on rare and
              unpredictable occasions a software glitch delays workers’ log-ins for
              as long as two to three minutes.
            An employer ordinarily distributes work schedules and schedule
              changes during working hours at the place of employment. But
              occasionally employees are notified of schedule changes by e-mail
              or text message during their off hours and are expected to read and
              acknowledge the messages.
            After their shifts have ended, employees in a retail store sometimes
              remain in the store for several minutes waiting for transportation.
              On occasion, a customer will ask a waiting employee a question, not
              realizing the employee is off duty. The employee — with the

                                           3
              employer’s knowledge (see maj. opn, ante, at p. 9) — spends a
              minute or two helping the customer.

       In situations like these, a requirement that the employer accurately account
for every second spent on work tasks may well be impractical and unreasonable; if
so, a claim for wages and penalties based on the employer’s failure to do so would
be inconsistent with California labor law, construed with the guidance of the
background rule codified in Civil Code section 3533.
       California law does, in short, make some allowances based on
considerations of practicality and reasonableness. It does not, however, permit an
employer to require an employee to regularly work for nontrivial periods of time
without providing compensation.
