                       December 12, 2023
          LIPEZ, Circuit Judge.        Motor carriers CRST Expedited

and CRST International ("CRST") use a "team driving model" to

transport goods across the country, whereby two drivers ride in

a truck and alternate their time between driving and resting in

the truck's sleeper berth.      This collective action requires us

to decide whether, as a matter of first impression, the time

these long-haul truck drivers spend in the sleeper berth is "on-

duty"   time    within   the   meaning     of   Department   of   Labor

regulations, and, if so, whether CRST must compensate a driver

who is on duty for 24 hours or more for time that driver spends

in the sleeper berth in excess of eight hours within a full 24-

hour period.    Granting summary judgment for former CRST drivers

Juan Carlos Montoya and others,1 the district court determined

that such time is compensable work.       We affirm.

                                  I.

A. Background

          CRST is a motor carrier providing trucking services

across North America that runs a driver training program for

aspiring long-haul truck drivers.        Montoya and the other members

of the collective action were trainee long-haul truck drivers

    1  Montoya and the other named plaintiffs originally brought
separate actions against CRST on their own behalf and on behalf
of others similarly situated.     See 29 U.S.C. § 216(b).    The
separate cases subsequently were combined through settlement
negotiations that disposed of all claims except the sleeper
berth claim.   For convenience, we refer throughout our opinion
only to Montoya's action.

                                - 3 -
participating            in    CRST's       program.      The    training      program    is

comprised of four phases.                   The first two phases are a practicum

enabling trainee drivers to earn a commercial driver's license

and a companion classroom-based course with instruction on the

practical use and application of these licenses.2                             During phase

three,          when     trainee        drivers        sign     an   eight-to-ten-month

employment contract and CRST begins to compensate them for their

driving, new trainees are matched with a more experienced CRST

driver to complete approximately four weeks of team driving.

When the more experienced driver determines that the trainee

driver is ready, the trainee advances to stage four, in which

the    trainee          is    matched       with   a    co-driver     to    complete     the

additional seven to nine months of the contract term as a team

driver.

                 CRST's team-based driver training program is uncommon.

CRST       is     one    of     the     few    companies       nationwide      that    hires

inexperienced            drivers      and     trains    them    in   teams.      The     team

driving model assigns to each truck two drivers who take turns

driving the vehicle.               These drivers structure their driving time

in accordance with the "Hours of Service" regulations of the

United          States       Department       of   Transportation       ("DOT").         The

regulations specify, in relevant part, that a driver may be "on

license and relevant driving experience may advance directly to
phase two.

duty" for a maximum of fourteen hours at a time.                   49 C.F.R.

§ 395.3(a)(2).          Within this fourteen-hour period, a driver may

only drive for a total of eleven hours; the remaining three

hours may be spent taking care of non-driving responsibilities,

such       as     loading    or   unloading     the   vehicle.      See     id.

§ 395.3(a)(3).          After fourteen hours of on-duty time, a driver

must take at least ten consecutive hours of time "off duty" as

defined by the DOT regulations, during which the driver cannot

drive,          load,   or    unload     the    vehicle,   or    have     other

responsibilities related to the truck and its equipment.                    See

id. §§ 395.3(a)(1); 395.2.             The dispute before us concerns this

"off-duty" time only.

                 CRST's team-driving approach typically results in one

person driving while the other driver is off duty (for purposes

of the DOT regulations) in the sleeper berth of the truck.3                 The

drivers can then switch when the off-duty driver has completed

the required ten-hour period.             Drivers regularly take more than

ten hours of sleeper berth time at a stretch, depending on how

driving teams structure their driving time; indeed, some drivers

have spent up to sixteen hours in the sleeper berth of the

       Off-duty time can also be spent in the passenger seat of
       3

the truck, but the record indicates that drivers spend most of
their off-duty time in the sleeper berth.

truck.4          CRST's approach allows the company to keep their trucks

in near continuous motion, for multiple days, while complying

with       DOT    regulations   limiting   the   hours   a   driver   can   spend

behind the wheel.            The drivers "trade . . . on and off until

they get from origin to destination," thereby allowing CRST to

"get twice the utilization out of the truck and keep that cargo

moving . . . twenty hours a day or more."

                  The sleeper berth of the truck is a driver's "living

quarters" during these long stretches of time on the road.                    The

space typically contains bunk beds, a sitting area, and perhaps

a microwave or small refrigerator, but does not have a bathroom

even though drivers are frequently there for ten or more hours

at a time while the truck is in motion.             Sleeper berths must, at

a minimum, measure 24 inches in width, 75 inches in length, and

24 inches in height (which is measured from the highest point of

       The record provides an example of how team drivers may
       4

schedule their driving.    Driver A may start the trip as the
driving teammate and drive for ten hours.      During this time,
Driver B is in the sleeper berth. After ten hours, the drivers
switch and Driver B drives for ten hours while Driver A rests.
The drivers continue to switch after each ten-hour period until
they get to their destination.    Alternatively, because drivers
"have a fourteen-hour window" before they must take ten hours
off, Driver A might complete a fourteen-hour shift of driving
and truck maintenance while Driver B spends fourteen hours in
the sleeper berth, and the drivers then switch. The record does
not clarify under what conditions a driver would be in the
sleeper berth for sixteen hours, considering that drivers must
rest after each fourteen-hour period, but the parties do not
dispute that "[t]here are several days on which CRST has
recorded twelve to sixteen hours of sleeper berth and other off-
duty time . . . for the named [plaintiffs]."

the mattress on the top bunk).                   49 C.F.R. § 393.76(a)(1).               When

in the sleeper berth, drivers are at liberty to pursue their own

activities         within      the    confines     of    the   space     and    facilities

provided          to   them.      Drivers    can    make       food,    connect    to     the

internet      if       internet      connectivity       is   available,        read,    watch

television or movies, and sleep.5                       When the truck is not in

motion -- for example, when the teammates swap over at a rest

stop -- drivers are also able to leave the truck and attend to

their       needs      before     resuming    driving.           CRST    explains        that

"[g]enerally [the drivers] eat and take care of personal hygiene

during these transitions."                  Drivers are free to manage their

time and schedules during a journey "[a]s long as they're still

on their plan to deliver that load on time[.]"                             In emergency

situations, the non-driving teammate may also be called upon to

help       with    a   maneuver      or   provide       emergency      assistance,       even

though he is "off duty" per the DOT's regulations.                                     See 49

C.F.R. § 395.1(b)(2).

                  Driver compensation is covered by a different set of

regulations, issued by the United States Department of Labor

("DOL").           The DOL regulations, which are discussed in detail

below, provide that employers can exclude a sleeping period of

no more than eight hours per day when calculating an employee's

       The record lacks information on whether CRST imposes rules
       5

on drivers for their sleeper berth time beyond the DOT
regulations.

                                            - 7 -
compensation.   See 29 C.F.R. § 785.22.6   CRST calculates the pay

owed to team drivers according to the total number of miles

dispatched to the team for the shipment.      Each member of the

driving team is paid one half of the total number of miles

attributed to the shipment at a rate of pay that corresponds

with the driver's level of experience, with less experienced

drivers receiving a lower rate of pay per mile.         Thus, the

hourly wage of the drivers can be calculated by dividing their

received pay by the total number of hours worked during the pay

period.   CRST does not count time spent in the sleeper berth as

hours worked and so does not include the sleeper berth hours in

the calculation of the drivers' hourly wage.       If the sleeper

berth time is counted as hours worked, however, CRST's drivers

receive an hourly wage that falls short of the minimum wage

under the FLSA.7   See 29 U.S.C. § 206.

     6 29 C.F.R. § 785.21 provides that "[a]n employee who is
required to be on duty for less than 24 hours is working even
though he is permitted to sleep or engage in other personal
activities when not busy." The compensability of sleeper berth
time for drivers with periods of duty less than 24 hours is not
at issue in this appeal.
     7 Montoya's salary for the first pay period in November 2014
provides a clear example of how CRST's formula works.     Montoya
began his phase three training on October 28, 2014, and he began
earning $0.25 per mile, in accordance with CRST's pay scale for
drivers of his level of experience.    In November 2014, Montoya
completed a 1,871-mile trip from Cedar Rapids, Iowa, to
Portland, Oregon. Since CRST pays its team drivers for one half
of the total miles on a trip, Montoya was paid for 935.5 miles.
At $0.25 per mile, this trip paid Montoya $233.88.       He also
received a signing bonus of $100, resulting in a total wage of

                               - 8 -
B. Procedural history

              Montoya filed suit against CRST in January 2016 on

behalf of himself and others who had participated in CRST's

driver training program.8          Montoya claimed, in relevant part,

that       CRST's   compensation   policies   violate   the   Fair    Labor

Standards Act, 29 U.S.C. §§ 201-219, because CRST does not pay

its drivers for hours spent in the sleeper berth that exceed the

DOL's excludable eight-hour sleeping period, and thus does not

meet the hourly minimum wage required by the FLSA.                   Montoya

moved for summary judgment on this claim.           Basing its decision

largely on its interpretation of the DOL regulations, the United

States District Court for the District of Massachusetts found

$333.88. Montoya's payroll statement reflects that he worked a
total of 33 hours during this pay period, per CRST's definition
of what constitutes hours worked.     Montoya also logged 15.61
hours of "excess sleeper berth time" during this period, meaning
time exceeding eight hours per day spent in the sleeper berth.
If the excess sleeper berth time is not included when
calculating Montoya's hourly pay, he received an hourly wage of
$10.12 ($333.88/33 hours). If the excess sleeper berth time is
included,   Montoya   received   an   hourly   wage   of   $6.87
($333.88/48.61 hours). The applicable minimum wage is $7.25 per
hour. 29 U.S.C. § 206.
       Although Montoya asserted several claims against CRST,
       8

only his claim challenging CRST's compensation for sleeper berth
time is at issue in this appeal.     The district court granted
Montoya's motion for certification of a collective action on
that claim pursuant to 29 U.S.C. § 216(b). See Montoya v. CRST
Expedited, Inc., 311 F. Supp. 3d 411, 419-27 (D. Mass. 2018).
The district court defined the class as "all individuals who
have participated as contract drivers in any phase of CRST's
Driver Training Program, at any time since December 22, 2013."

that       drivers'    sleeper      berth   time     exceeding       eight       hours   is

compensable under the FLSA.                 Montoya v. CRST Expedited, Inc.,

404 F. Supp. 3d 364, 393-95 (D. Mass. 2019).                         Thus, the court

concluded, the additional sleeper berth time must be included

when calculating whether CRST pays its drivers an hourly wage

that meets the minimum wage requirements under the FLSA.                                 See

id.    CRST appealed the summary judgment for Montoya.9

               We     review    the   district       court's   grant        of     summary

judgment de novo.              Giguere v. Port Res. Inc., 927 F.3d 43, 47

(1st Cir. 2019).          Summary judgment is proper when there is "no

genuine      dispute     as    to   any   material    fact"    and    the    movant      is

"entitled to judgment as a matter of law."                       Fed. R. Civ. P.

56(a).

               The parties do not dispute any of the facts pertinent

to the sleeper berth claim as laid out above.                           Rather, they

disagree as to whether sleeper berth time exceeding eight hours

per day is compensable work under the FLSA.

       CRST filed a notice of appeal after the district court
       9

issued a separate and final judgment on the sleeper berth claim
and subsequently filed a second notice of appeal after the court
entered final judgment on the remaining claims. While there was
some initial dispute about the timeliness of CRST's notices of
appeal, we allowed the matter to proceed and granted the
parties' joint motion to consolidate the two notices of appeal,
thereby resolving the timeliness question.   As noted, CRST has
appealed only from the district court's summary judgment for
Montoya on the sleeper berth claim.

A. Compensable Work Under the FLSA

              1. The Legal Framework

              The FLSA      currently requires employers to compensate

employees for each hour of work at a rate of at least $7.25 an

hour.     29 U.S.C. § 206(a).          Although Congress has never defined

what constitutes "work" under the FLSA, the Supreme Court, in

dealing with FLSA cases,             has described work as "physical or

mental     exertion       (whether   burdensome     or     not)     controlled     or

required by the employer and pursued necessarily and primarily

for the benefit of the employer and his business."                     Tenn. Coal,

Iron & R.R. Co. v. Muscoda Local No. 123, 321 U.S. 590, 598

(1944).       In subsequent cases, the Supreme Court has clarified

that this "exertion" can be negligible, as "an employer, if he

chooses, may hire a man to do nothing, or to do nothing but wait

for something to happen."              Armour & Co. v. Wantock, 323 U.S.

126,    133   (1944).        In   cases   involving      waiting,    the    critical

question is whether an employee is "engaged to wait" (which is

generally compensable) or "wait[ing] to be engaged" (which is

noncompensable).          Skidmore v. Swift & Co., 323 U.S. 134, 137

(1944).       To answer this question and thereby determine whether

an employee's time is compensable under the FLSA, we apply what

other    circuits     have    dubbed      the   "predominant      benefit       test":

employee      time   is    compensable     work   when    this    "time    is    spent

predominantly for the employer's benefit," which "is a question

                                       - 11 -
dependent upon all the circumstances of the case."                         Armour, 323

U.S. at 133; Singh v. City of New York, 524 F.3d 361, 367-69 (2d

Cir.    2008)      (applying     the    "predominant-benefit        test");       Roy   v.

County      of    Lexington.      141    F.3d    533,    544-45   (4th     Cir.    1998)

(same).

                 Circuit courts        have applied the predominant benefit

test to determine whether employee time is compensable work in a

variety of circumstances, including on-call time, mealtime, and

commuting        time.10    In    so    doing,    they    have    identified      useful

factors      to     guide   our    analysis       of    whether    "time     is    spent

       We note that the parties have not identified, nor have we
       10

found, any published circuit court decisions addressing whether
sleeper berth time constitutes compensable work for the purposes
of the FLSA. Indeed, the Ninth Circuit appears to be the sole
federal appellate court that has contemplated this question, but
the resulting unpublished opinion concludes in a single sentence
that sleeper berth time is non-compensable, with little analysis
of the applicable legal standard or the circumstances of the
case.   See Nance v. May Trucking Co., 685 Fed. App'x 602, 605
(9th Cir. 2017) ("Reviewing de novo, . . . we affirm because the
district court properly relied on the persuasive authority of
federal and state regulations saying drivers are not entitled to
compensation for time they are permitted to sleep in the berths
of moving trucks.").
     In a similar vein, we note that some district courts have
addressed whether sleeper berth time is compensable under the
FLSA.   See, e.g., Roberts v. TransAm Trucking, Inc., 2023 WL
6376756 (D. Kan. Sept. 29, 2023); Haworth v. New Prime, Inc.,
448 F. Supp. 3d 1060 (W.D. Mo. 2020); Julian v. Swift Transp.
Co. Inc., 360 F. Supp. 3d 932 (D. Ariz. 2018); Browne v. P.A.M.
Transp., Inc., No. 5:16-CV-5366, 2018 WL 5118449 (W.D. Ark. Oct.
19, 2018).    These decisions have addressed the issue under
differing procedural postures -- for example, in the context of
class certification -- and have reached varying conclusions.
Accordingly, we focus our analysis on the treatment of analogous
issues by circuit courts.

predominantly for the employer's benefit."             Armour, 323 U.S. at

not previously engaged with the predominant benefit test, we

have recognized the "FLSA's usual rule . . . that an employer

must pay an employee for all time the employee is required to

spend at a worksite."11          Giguere, 927 F.3d at 47.         Other courts

have incorporated this "usual rule" into their application of

the predominant benefit test in on-call cases, determining that

the    employee's     physical    location   and   ability   to    leave   that

location are important factors to consider when applying the

test.        See, e.g., Rapp v. Network of Cmty. Options, Inc., 3

F.4th 1084, 1087 (8th Cir. 2021) (explaining that factors "[t]o

determine whether on-duty waiting or sleeping time is working

time" include "whether [the employee] is required to remain on

or    about    the   premises    during   such   time");   Rutlin    v.    Prime

Succession, Inc., 220 F.3d 737, 744 (6th Cir. 2000) (determining

that an employee was working even though he was at home for the

       11

group homes for adults with developmental disabilities violated
the FLSA when it did not compensate residential employees for
overnight time spent on the employer's premises, a question that
turned on the DOL's guidance outlining the parameters of the
"workweek" for employees who "reside[] on the employer's
premises." Giguere, 927 F.3d at 47-48. While we did not apply
the predominant benefit test in that situation, our recognition
of the FLSA's foundational rule (that an employer must pay an
employee for all time the employee is required to spend at a
worksite) is pertinent here.

on-call period, in part because he had to take landline phone

calls and thus could not leave home).

              The employee's ability to leave the workplace has also

proved an important factor in mealtime cases.                             For instance, the

Fourth Circuit -- applying the predominate benefit test -- found

that medical employees' mealtimes were not for the employer's

predominant benefit, and therefore not compensable work, when

the employee could leave the workplace for the meal and was not

interrupted during that time.                See Roy, 141 F.3d at 544-46.

              An employee's ability to engage in personal activities

during      the    contested       time    also    informs         whether    the    time    is

predominantly        for     the     employer's         benefit.            The    employee's

ability to use his time for recreational purposes may suggest

that he is waiting to be engaged, but this determination depends

on the degree of freedom with which the employee can pursue

leisure activities and whether he can spend time "in the ways

the [employee] would have chosen had [he] been free to do so."

Skidmore, 323 U.S. at 139.                  Hence, the Supreme Court found in

Armour that firefighters who were required to spend on-call time

in    the   fire     hall,   where        they    had   to    respond       to    alarms    and

perform minor maintenance work but could otherwise engage in

recreational activities such as playing cards and listening to

the    radio,      were    engaged    in     compensable           work    under    the    FLSA

because      their    waiting       time    was    for       the    employer's      benefit.

                                           - 14 -
Armour, 323 U.S. at 132-34.              Conversely, the Eleventh Circuit

determined that on-call police officers who could remain at home

or travel so long as they had a beeper were not entitled to

compensation, as the employees "could do anything they normally

did so long as they were able to respond to a call promptly" and

the   time    was    therefore    "not      used    predominantly         for     the

employer's benefit."      Birdwell v. City of Gadsden, 970 F.2d 802,

808-10 (11th Cir. 1992).

             Courts also assess the burden on the employee when

determining whether employee time is for the employer's benefit.

Applying     the    predominant    benefit     test     in     the      context    of

commuting,    the    Second    Circuit    determined        that   an    employee's

commute was not compensable work because the only work-related

activity that the employee had to perform during the commute was

to carry a briefcase of materials with him.                 See Singh, 524 F.3d

at 368-69.      The additional time and effort that this activity

required of the employee presented such a "minimal burden" that

the court concluded "the [employer] is [not] the predominant

beneficiary of this time."        Id.

             The DOL's own regulations interpreting the FLSA build

on the standards for compensable work outlined in the above

jurisprudence.        Citing    Skidmore,     the     DOL    explains      that    an

employee between assignments who "is unable to use the time

effectively for his own purposes" is working, because the time

                                   - 15 -
"belongs to and is controlled by the employer" and thus the

employee    is   "engaged      to   wait."        29     C.F.R.    § 785.15    (citing

Skidmore, 323 U.S. at 137).                An employee who is "completely

relieved    from    duty,"     however,      is    not     working.       29     C.F.R.

§ 785.16.     With respect to truck drivers, the DOL explains that

a driver is relieved from duty when, for example, he has a six-

hour layover between delivering goods and waiting for his next

shipment to be loaded, provided he can leave the worksite and

does not have to take care of the truck during this time.                             See

id. (citing Skidmore, 323 U.S. at 137).

            2. Sleeper Berth Time

            We     turn   to    the     application        of     this   "predominant

benefit test" to the sleeper berth time in the present case.

CRST argues that none of the time that team drivers spend in the

sleeper berth should be considered work under the FLSA because

the drivers are "waiting to be engaged" during that time and

thus their time is their own.                    In urging us to          reach      this

conclusion, CRST observes that drivers can sleep, fix meals,

watch television, and access the internet while in the sleeper

berth.     Further, CRST contends that because the driving teammate

is responsible for all work-related duties while the non-driving

teammate rests, and because CRST employs its drivers to drive,

not   to   rest,    the   sleeper       berth     time    is    primarily      for   the

employee's       benefit.             Finally,      CRST        argues    that        the

                                        - 16 -
classification of the sleeper berth time as off-duty time by the

DOT regulations renders it non-compensable under the FLSA.

              Montoya,      on     the    other      hand,    claims    that      drivers'

confinement to the restrictive environment of the sleeper berth

means that such time predominantly benefits the employer, and

thus is compensable work.                 Moreover, he underscores that CRST's

team-driving business model relies on, and profits substantially

from,    drivers      continuing         to    travel    while      taking   their   rest

period, rendering this time for the employer's benefit.

              To assess these competing claims, we turn first to

CRST's regulatory argument.                   It is true, as CRST asserts, that

the DOT's Hours of Service regulations require drivers to be

"relieved from work and all responsibility for performing work"

during the ten-hour "off-duty" period and specifically exclude

"time spent resting in a sleeper berth" from "[o]n-duty time."

49 C.F.R. § 395.2.           CRST's reliance on the DOT regulations to

determine      what      constitutes           compensable      work    is     misplaced,

however.       The DOT regulations concern driver and road safety

and,    unlike     the     FLSA,    do        not   address    worker    compensation.

Compare Hours of Service of Drivers, 65 Fed. Reg. 25540, 25540

(proposed     May     2,    2000)        (noting     that     the   Hours    of   Service

regulations concern drivers' resting time to "reduce the risk of

drivers operating commercial motor vehicles (CMVs) while drowsy,

tired,   or    fatigued      [and]        to    reduce      crashes    involving     these

                                           - 17 -
drivers") with 29 U.S.C. § 206 (establishing the minimum wage).

The DOT's road safety regulations are thus of little help in

determining what constitutes compensable working time under the

FLSA.

          Indeed, the DOT itself has recognized that using DOT

classifications       of     "off-duty"        time     to      guide      issues    of

compensability       is     misplaced       and   can    result       in     employers

circumventing the FLSA's requirements.                  See Hours of Service of

Drivers, 65 Fed. Reg. at 25564-65 (noting that "motor carriers

generally have relied upon the [DOT regulations] under 49 CFR

part 395 . . . to calculate the minimum wage required to be paid

to the driver for each workweek. . . .                    [S]ome motor carriers

that have not understood the difference [between DOT and DOL

regulations]    may       miscalculate      the   minimum     wage,      placing    the

motor carrier in violation of the FLSA.").12                       We thus reject

CRST's   invitation         to     interpret      the    FLSA     using      the    DOT

regulations    and    turn       to   the   application      of   the      predominant

benefit test.

          First,      the        drivers'   confinement      to    the      restricted

environment of their workplace suggests that such time is for

CRST's benefit.       As the parties acknowledge, drivers spend the

    12 The DOL regulations in question, which we turn to below,
were promulgated pursuant to the FLSA and provide guidance on
employee compensation.   See 29 C.F.R. § 785.1 (noting that the
DOL regulations outline "the principles involved in determining
what constitutes working time" under the FLSA).

                                        - 18 -
vast majority of their time not spent driving in the sleeper

berth of a moving truck.        They remain at their place of work,

with their freedom of movement severely curtailed, throughout

the sleeper berth time, regularly spending ten, twelve, and even

sixteen hours in the confines of this small space.                  The drivers

can    leave     the   workplace      only      when     the   truck     stops,

distinguishing this case from many of the contexts that other

circuits have considered.       See, e.g., Birdwell, 970 F.2d at 808-

10 (emphasizing that employees were free to leave the worksite

to engage in personal pursuits during the time at issue); Rapp,

3 F.4th at 1087 (same); Roy, 141 F.3d at 545-46 (same).

              Although CRST recognizes that employees are confined

to the sleeper berth, it repeatedly emphasizes that the drivers

may use the sleeper berth time for personal activities such as

eating, watching movies, and connecting to the internet, making

such   time    predominantly   for    the     drivers'   benefit.      Somewhat

implausibly, CRST contends that drivers can do "anything . . .

they [have] a mind to do" during their sleeper berth time.

              CRST's argument turns a blind eye to the limitations

inherent in the drivers' physical location.               Though drivers may

be able to engage in some leisure activities, the nature of

these activities is restricted by the drivers' presence in the

sleeper berth of a moving truck -- a small space, containing

only some basic living essentials, that drivers cannot leave

                                     - 19 -
until the truck stops moving.                The minimum height of the sleeper

berth is a mere 24 inches                as measured from the top of the

mattress installed in the berth, see 49 C.F.R. § 393.76(a)(1),

meaning that drivers may struggle to stand or even sit up in bed

in the sleeper berth.            The driver in the sleeper berth is also

in   constant       proximity    to    the    noise    of    the   truck's   engine,

further reducing drivers' ability to sleep, relax, or engage in

leisure activities of their choice.                   In short, CRST's argument

that the drivers' time is their own because they can use it as

they   wish    is    unpersuasive       considering      the    drivers'     physical

confinement in a restrictive space that is ill-equipped for many

activities.

              Moreover,       CRST's     argument      overlooks       the    Supreme

Court's jurisprudence establishing that the ability to engage in

some leisure activities does not, in and of itself, render an

employee's time for the employee's own benefit.                     In Armour, the

Court found that the employee firefighters' time benefited the

employer and was compensable work even though they could play

cards, listen to the radio, or eat while waiting for the next

alarm.      Armour, 323 U.S. at 132-34.            As the Court explained, the

time   did    not    become     the    employee's     own    "merely   because     the

nature of the duty left time hanging heavy on the employees'

hands and because the employer and employee cooperated in trying

to   make     the    confinement       and    idleness      incident   to    it   more

                                        - 20 -
tolerable."          Id. at 134.        Similarly, here, the drivers' time is

not their own merely because they can pass the time spent in the

sleeper-berth         by     watching    a    movie    or    surfing    the     internet,

activities that are the modern-day equivalents of cards and the

radio.

               The    fact    that   the      drivers     are      typically    traveling

during time spent in the sleeper berth also suggests that such

time is for CRST's benefit, given the importance of continuous

travel    to    CRST's        business.         CRST's      team    driving     approach,

requiring drivers to trade on and off their driving and non-

driving times until they arrive at their destination, allows

CRST's    trucks        to    remain     in     near     continuous         motion    while

complying with DOT regulations limiting drivers' hours behind

the wheel.       CRST benefits enormously from the team driving model

as the company makes its deliveries in approximately half the

time that it would take a solo driver to complete the same trip.

Indeed, CRST understands the necessity of drivers' sleeper berth

time to the company's bottom line,                       explaining that           its team

driving model allows it to "get twice the utilization out of the

truck and keep that cargo moving . . . twenty hours a day or

more."     Such       speed     of   travel     is    made   possible       only     by   the

resting   driver        resetting       their    driving     hours     in    the     sleeper

berth while their teammate continues to drive.

                                          - 21 -
            Finally, we consider whether time spent in the sleeper

berth burdens the driver confined therein.                  While the record

does not contain examples of drivers' sleeper berth time being

interrupted for work, the nature of the team driving setup means

that the driving teammate may call on the resting teammate to

provide emergency assistance, even during the mandated ten-hour

period defined as "off-duty" by the DOT regulations.                       See 49

C.F.R. § 395.1(b)(2) (providing that, in "emergency conditions,"

a driver may complete the shipment even if the driving time

falls outside of the maximum driving time "without being in

violation    of    the    provisions     of   the     regulations").          The

discomfort of being confined in a small and noisy space, as well

as the possibility of interruptions, suggest that the sleeper

berth time presents more than a "minimal burden" on drivers.

See Singh, 524 F.3d at 368.           Considering the restrictions that

sleeper   berth    time   places   on   drivers     and   its   centrality     to

CRST's    team    driving    model,     we    conclude      that    such     time

predominantly benefits the employer.

B. The DOL Regulations

            As a general matter, time that predominantly benefits

the   employer    is   compensable     work   under   the   FLSA,   absent     an

exception to compensability provided for in the statute or DOL

regulations.      See Tenn. Coal, Iron & R.R. Co., 321 U.S. at 602

(stating that the FLSA "guarantee[s] compensation" for all hours

                                     - 22 -
worked); Armour, 323 U.S. at 134 (stating that the act provides

for some "exclu[sions]" from working time).13   We therefore turn

to the application of the DOL regulations to this dispute.     At

the heart of the parties' dispute are two regulations governing

sleep time: 29 C.F.R. § 785.22 and 29 C.F.R. § 785.41.    Section

785.22(a) reads, in pertinent part:

         Where an employee is required to be on duty
         for 24 hours or more, the employer and the
         employee may agree to exclude bona fide meal
         periods and a bona fide regularly scheduled
         sleeping period of not more than 8 hours
         from hours worked . . . . If [the] sleeping
         period is of more than 8 hours, only 8 hours
         will be credited.

Section 785.41 reads:

         Any work which an employee is required to
         perform while traveling must, of course, be

    13  In applying the predominant benefit test and upholding
the general principle that employers must pay employees for
hours worked, circuit courts have recognized that both statutory
and   regulatory   provisions   identify  some   exceptions   to
compensability for otherwise compensable work.       See, e.g.,
Birdwell, 970 F.2d at 804 (explaining that, "[i]n general,
employers are required to pay employees . . . for hours worked"
but recognizing that, in the case of some overtime hours, the
FLSA provides "an exception to this rule" depending on a number
of factors enumerated in the statute); Gelber, 14 F.4th at 1280-
86 (noting that the predominant benefit test "governs the
general question [of] whether time spent is compensable work,"
but recognizing that the DOL regulations provide that an
employer may "deduct meal breaks" from an employee's "otherwise
compensable" time in certain circumstances); Singh, 524 F.3d at
367-68 (explaining that "whether an employee's expenditure of
time is considered work under the FLSA turns in part on whether
that time is spent predominantly for the benefit of the
employer," but recognizing that some statutory and regulatory
provisions "exempt[] employers from compensating employees" for
certain activities).

                             - 23 -
           counted as hours worked.    An employee who
           drives a truck . . . or an employee who is
           required to ride therein as an assistant or
           helper, is working while riding, except
           . . . when he is permitted to sleep in
           adequate   facilities   furnished  by   the
           employer.

           Montoya      does    not   dispute    that       CRST    can   deduct     an

eight-hour sleeping period from drivers' compensable hours, nor

does he challenge the adequacy of the sleeping facilities.                          The

sole   dispute    between      the    parties    is      whether,     under       these

regulations, CRST can deduct time drivers spend in the sleeper

berth beyond the eight-hour exception set forth in § 785.22 from

drivers' compensable work.

           CRST    argues      that   § 785.41     is       the    only   applicable

regulation.       In urging us to ignore § 785.22 entirely, CRST

argues that employees are not "on duty for 24 hours or more"

because   they    are   not    working    during      the    time    spent    in   the

sleeper berth and, per DOT regulations, drivers are only "on

duty" for shifts of 14 hours or less.                 CRST therefore contends

that   § 785.41    alone       applies,   and      the      plain    text    of    the

regulation compels us to conclude that employers can deduct any

amount of time that an employee is confined to the sleeper berth

from compensable hours, because the employee is "permitted to

sleep in adequate facilities" during such time.

           Montoya counters that both sections 785.22 and 785.41

apply because drivers are working when they are in the sleeper

                                      - 24 -
berth and are therefore "on duty" for twenty-four hours or more,

as that concept is defined by DOL regulations that, unlike the

DOT regulations, construe the FLSA.             See 29 C.F.R. § 785.15 (an

employee is "engaged to wait" and thus "[o]n duty" when he is

"unable to use [his] time effectively for his own purposes,"

because it "belongs to and is controlled by the employer").

Reading sections 785.22 and 785.41 together, Montoya argues that

CRST can deduct a period of sleep time from drivers' compensable

hours, but that this sleeping period can be no more than eight

hours.    Thus, Montoya argues, CRST must compensate drivers for

all sleeper berth time extending beyond the eight-hour sleeping

period.

§ 10:51      (3d   ed.,   2023)    (noting     that   courts   should       review

regulations in context).          In so doing, we "construe a regulation

in   light    of   the    congressional   objectives     of    its   underlying

statute."      United States v. Lachman, 387 F.3d 42, 52 (1st Cir.

2004).    It is well established that the underlying statute here,

                                     - 25 -
the FLSA, was designed to protect workers' living standards and

health    by     guaranteeing         adequate     compensation,     and   the     DOL's

regulations          provide    guidance      to   employers    in   upholding       the

protections of the FLSA.                See 29 U.S.C. § 202(a) (noting that

Congress sought to guard against "labor conditions detrimental

to the maintenance of the minimum standard of living necessary

for health, efficiency, and general well-being of workers"); 29

principles       involved       in    determining     what     constitutes    working

time" under the FLSA).

               When reading the regulations against this                     statutory

background, we do not give force to one phrase in isolation.

See Util. Air Regul. Grp. v. E.P.A., 573 U.S. 302, 321 (2014)

(noting       that    reading    a    provision      in   context    may   produce    a

different meaning than reading a provision in isolation); Jette

2021) (explaining that we "construe the regulation in light of

language is used, and the broader context of the [regulation] as

a whole'" (quoting In re Fin. Oversight & Mgmt. Bd. for P.R.,

919 F.3d 121, 128 (1st Cir. 2019))).                      Rather, we must read a

body     of    regulations       in    harmony,      avoiding    conflict     between

provisions        and     "giving        effect,      when     possible,      to     all

                                         - 26 -
provisions."        McCuin v. Sec'y of Health & Hum. Servs., 817 F.2d

161, 168 (1st Cir. 1987).

              2. Application of the Regulations

              We    first    consider      whether   § 785.22     applies   to    the

facts before us.            Section 785.22 deals with sleeping time and

specifies that when employees are "required to be on duty for 24

hours or more, the employer may exclude a sleeping period of not

more   than    eight      hours."       We    understand   CRST    to   argue    that

§ 785.22 does not apply to its drivers because they are not "on

duty for 24 hours or more."             CRST contends that its drivers work

for only fourteen hours at a time because that is the maximum

number of hours that the DOT's regulations permit a driver to be

"on duty," as the term is used in the DOT regulations, before

taking a rest period in the sleeper berth, which CRST argues is

not compensable work.               However, our predominant benefit test

analysis necessarily informs our application of § 785.22.                       As we

have explained in Part II.A, the sleeper berth time is for the

benefit   of       the   employer    and     therefore   constitutes     'on    duty'

time, as that term is set forth in 29 C.F.R. § 785.15 and used

in 29 C.F.R. § 785.22.           Since CRST's drivers are "on duty," for

purposes of the FLSA, when in the sleeper berth, and may spend

more than 24 consecutive hours either in the sleeper berth or

driving and performing other work tasks, team drivers are "on

                                        - 27 -
duty" for periods of twenty-four hours or more.                      Section 785.22

thus applies.

             The question then becomes how we read § 785.22 with

§ 785.41, given the statutory and regulatory context and the

facts before us.          Section 785.41 deals with travel time and

specifies       that   employees    who   perform      work    while       driving    or

riding in a truck are "working while riding, except . . . when

[they are] permitted to sleep in adequate facilities furnished

by   the    employer."       CRST's     argument   would      have    us    read   into

§ 785.41 an exception to the sleeping-time cap of § 785.22 for

employees who work while traveling, but it fails to offer a

rationale to explain why the DOL would have created such an

exception.        Rather, the better reading of the regulations is

that they work together: § 785.41 provides that employees who

work    while    traveling    in   a    truck    are   "working      while    riding"

except during a sleeping period.                 Section 785.22 provides that

such    a   sleeping     period    is   non-compensable,        but    only     for    a

maximum of eight hours.14               This reading gives effect to the

language of both regulatory provisions and is consistent with

the overarching statutory and regulatory framework protecting

employees       from   exploitative      compensatory      practices.          See    29

        It is immaterial whether the remaining sleeper berth time
       14

is part of the drivers' DOT-required ten-hour "off-duty" period.
As explained above, all such time is compensable work under the
FLSA   and   the  DOT   definitions   of  time   do   not  affect
compensability.

                                        - 28 -
U.S.C.    § 202(a);    Giguere,      927   F.3d   at   50    (acknowledging     the

FLSA's remedial purposes and protective policy objectives).

            CRST's      reading       of    § 785.41,        which      forecloses

compensation for any hours that the driver spends in the sleeper

berth, contradicts these protective principles.                      Taken to its

logical    conclusion,      CRST's    reading     of   § 785.41      would   permit

employers to avoid compensating drivers by confining them to the

sleeper berth for an unlimited number of hours simply because

that is time in which they are "permitted to sleep," even though

-- as CRST acknowledged in a deposition -- it is unreasonable to

propose that a driver would be sleeping for the ten or more

hours per day spent in the sleeper berth.15

            Moreover, CRST's reading of § 785.41 would have us

reject     the     predominant-benefit         test     that     Supreme      Court

precedents require us to apply. See Armour, 323 U.S. at 133

(explaining that "time [that] is spent predominantly for the

employer's       benefit"   is    working    time);     29     U.S.C.   §    206(a)

(guaranteeing compensation for working time)."

            For a similar reason, CRST's argument that § 785.41 is

a specific regulatory provision that trumps the more general

     15  Charles Haffenden, a former CRST vice president,
recognized in a July 2017 deposition that it would be hard for a
person to spend more than ten hours per day sleeping, saying: "I
find it personally hard to sleep more than about seven hours at
a stretch.   . . .   I don't know anybody that could spend ten
hours in there [sleeping] continuously."

                                      - 29 -
provision of § 785.22 is unpersuasive.                      CRST is correct that

when    a   specific   provision       of    a   regulation        conflicts      with     a

general one, the specific provision ordinarily governs.                                  See

Tasker v. DHL Ret. Sav. Plan, 621 F.3d 34, 43 (1st Cir. 2010);

cf.    Edmond    v.    United        States,     520      U.S.     651,    657        (1997)

("Ordinarily,     where       a   specific       provision        conflicts       with    a

general one, the specific governs.").                    But here, even if we were

to characterize the regulations in the way CRST argues,16 the two

provisions are not in conflict with one another.                          Indeed, they

must be read harmoniously to avoid direct contradiction with

each    other   and    with    the    outcome       of    our    application      of     the

predominant     benefit       test.         Since    the        caselaw   informs        our

understanding     of     the      regulations        --    notably,       as     we     have

explained, our understanding of whether the drivers are "on duty

for 24 hours or more" for the purposes of § 785.22(a) -- we

cannot adopt a reading of the regulations that is irreconcilable

with the background law.

             3. Wage and Hour Division Opinion Letters

             As a final matter, we address opinion letters from the

DOL's Wage and Hour Division ("WHD") that both parties invoke to

       16CRST argues that § 785.22 is a general provision
governing sleep time and § 785.41 is a "truck-driving specific"
provision. In response, Montoya argues that § 785.41 is no more
specific than § 785.22, as the two provisions address different
issues -- § 785.22 concerns compensation for sleep and meal
periods, and § 785.41 concerns compensation for all employees
who work while traveling.

                                        - 30 -
support their differing interpretations of the regulations.                          To

the extent that CRST asks us to defer to one such letter from

2019 -- which, as discussed below, rescinded earlier letters and

opined that sleeper berth time is non-compensable, but which the

agency states no longer represents the agency's views -- we may

do so only to the extent that the letter is persuasive based on

the factors outlined by the Supreme Court in Skidmore, 323 U.S.

at   140.          The    "mix    of      factors"      we    consider     to     gauge

persuasiveness         includes     "the     thoroughness       evident     in     [the

agency's]    consideration,         the    validity     of    its   reasoning,     [and

the] consistency [of its interpretation] with earlier and later

pronouncements."          Merrimon v. Unum Life Ins. Co. of Am., 758

F.3d 46, 55 (1st Cir. 2014) (alterations in original) (quoting

Doe v. Leavitt, 552 F.3d 75, 81 (1st Cir. 2009)).                       The validity

of the agency's reasoning is the "most salient . . . factor[]"

in gauging persuasiveness.             Id. (quoting Doe, 552 F.3d at 82).

             Since the 1960s, the WHD has published at least five

opinion     letters      clarifying       that   the    DOL   regulations       require

employers     to       compensate      employees       for    sleeper     berth    time

exceeding eight hours.              See U.S. Dep't of Labor, Wage & Hour

Div., Opinion Letter FLSA-213 (Jan. 6, 1964); U.S. Dep't of

Labor,    Wage     &   Hour   Div.,     Opinion    Letter      FLSA-214    (Feb.    17,

1964); U.S. Dep't of Labor, Wage & Hour Div., Opinion Letter

FLSA-235 (Nov. 18, 1966); U.S. Dep't of Labor, Wage & Hour Div.,

                                          - 31 -
Opinion Letter SCA-117 (Apr. 26, 1978); U.S. Dep't of Labor,

Wage & Hour Div., Opinion Letter SCA-118 (June 22, 1979).                 These

letters,    and   the     Secretary    of     Labor's    briefing   in     this

litigation,    explicitly    state     that   § 785.22    and   § 785.41    are

consistent with one another, "must be read together," and that,

therefore, "a maximum of 8 hours per day of sleeper berth time

is excludable from hours worked for on-duty periods of 24 hours

or more."

            In support of its position that we should look only to

§ 785.41, CRST asks us to defer instead to one short-lived 2019

opinion letter.        In that one letter, the WHD rescinded its five

prior letters and adopted the new position that, under § 785.41,

"the time drivers are relieved of all duties and permitted to

sleep in a sleeper berth is presumptively non-working time that

is   not    compensable"     because    the    prior     interpretation     was

"unnecessarily burdensome for employers."               U.S. Dep't of Labor,

Wage & Hour Div., Opinion Letter FLSA2019-10 at 3 (Jul. 22,

2019).     The WHD then withdrew the 2019 letter on February 19,

2021, explaining that it was "inconsistent with longstanding WHD

interpretations regarding the compensability of time spent in a

truck's sleeper berth."       U.S. Dep't of Labor, Wage & Hour Div.,

Opinion       Letter      Search       (FLSA2019-10),        available       at

https://www.dol.gov/agencies/whd/opinion-letters/search                   (last

                                   - 32 -
visited Sep. 14, 2023).               The WHD also reinstated the previously

withdrawn opinion letters.               See id.

               In arguing for deference to the 2019 opinion letter,

CRST claims that it accurately represents the DOL's pre-1960s

guidance on the compensability of sleeper berth time and thus

returns       the    DOL's       interpretation      of     the    regulations           to   its

original meaning.            In support of this argument, CRST points to a

1943 WHD press release stating that "[t]ruck drivers riding in

the trucks' sleeping berths while the relief driver is at the

wheel       need    not    be     compensated,"      U.S.      Dep't     of    Labor,      Press

Release R-1933, Hours Worked in Trucking Clarified (Feb. 15,

1943), along with a statement in the WHD's 1948 Field Operations

Handbook       that       "time    actually     spent     in     the    sleeping         berths"

should not be considered "hours worked,"                          U.S. Dep't of Labor,

Field Operations Handbook, Hours Worked, Part 130.41 (1948 ed.,

rev. 1949).

               We    agree,       however,    with     Montoya         and    his    amici     --

including the Secretary of Labor -- that the 2019 opinion letter

is    not    entitled       to    deference.       That     is    so     for    two      primary

reasons.           First, the letter provides little justification for

its    significant         departure     from    the      WHD's    position         of    almost

sixty years.          Simply stating without more that the WHD's prior

position was "unnecessarily burdensome for employers" does not

evince        thoroughness          or   considered            reasoning,           especially

                                          - 33 -
considering        the    policy      rationales         underscoring            the    FLSA          that

seek to protect employees.

              We      find       similarly         unsatisfactory                the        letter's

conclusory assertion that "WHD disagrees with recent judicial

decisions      that      have    regarded       sleeper      berth           time      as       on-duty

sleeping      time,      rather       than   off-duty       travel           time,"         a    remark

unadorned by any analysis of the reasoning in those cases or any

explanation for the disagreement.                       Likewise, the letter provides

no    basis        for    its      assertion        that         it        "understands              [its

interpretation]           to    reflect      the        prevailing          practice            in    the

trucking      industry,"         nor    does       it     cite        any     legal     authority

explaining why that would be a relevant consideration.                                          And the

letter simply declares that the regulatory scheme marks a "clear

distinction between [compensable] on-duty sleep time . . . and

[non-compensable] non-working time when the employer permits the

employee      to    sleep"      without      considering         whether         §§ 785.22             and

785.41    should         be    read    in    conjunction,             as     previous           opinion

letters had done, or explaining its refusal to do so.

              It is of little import that, as CRST contends, the

2019 letter may reflect WHD guidance on the compensability of

sleeper     berth        time   contained       decades          ago        in   pre-1960s             WHD

statements, such as the 1943 press release and 1948 handbook.

The   DOL     regulations         at    issue       here     were           adopted     in           1955,

including the regulations addressing the eight-hour cap on non-

                                             - 34 -
compensable sleeping time, and the adoption of the regulations

explicitly superseded prior opinions put forth by WHD.                               See U.S.

Dep't of Labor, Wage & Hour Div. Interpretive Bulletin Part 785,

20 Fed. Reg. 9963 (Dec. 24, 1955); U.S. Dep't of Labor, Wage &

Hour Div., Opinion Letter FLSA-214 (Feb. 17, 1964) (explaining

that    WHD   statements          predating     the     DOL    regulations          had    been

superseded by subsequent guidance).17                   Without further reasoning,

the 2019 letter does not support deference to its opinion.

              Second,       the    2019   letter      adopts        a    position    that    is

irreconcilable        with    the    previous      five       WHD       letters   addressing

this    issue.        The     pre-2019     letters        maintain         the    consistent

position that the maximum number of hours that an employer can

deduct for time spent in the sleeper berth of a truck is eight

hours, and they offer reasoned justification for WHD's position.

For    example,       the     pre-2019     letters        explicitly          address        the

interaction      of     the       regulations      on    sleeping          time     with    the

regulations on travel.              The 1978 letter explains that §§ 785.22

and 785.41 "must be read in conjunction and not as separate

positions     regarding       sleeping      time.        As    section       785.22        makes

Letter SCA-117 (Apr. 26, 1978).              In the same vein, the 1979

letter outlines the development of Supreme Court caselaw on the

compensability of waiting time to contextualize the regulations,

before reiterating that "it has long been our position that

section 785.41 must be read in conjunction with section[] . . .

[785].22" and stating that "section 785.41 does not alter the

general rules on sleep time."           U.S. Dep't of Labor, Wage & Hour

Div., Opinion Letter SCA-118 (June 22, 1979).18

            These    pre-2019      letters     are   consistent   internally

-- they represent more than five decades of the same policy --

and consistent with the purpose of the statutory and regulatory

scheme, unlike the irreconcilable and unreasoned 2019 letter.

     18 The 1979 opinion letter also endorses the view, not
addressed by the parties, that in an on-duty period extending
beyond 24 hours, employers may exclude a maximum of one
additional hour of sleep time for each hour on duty beyond 40
hours, such that a driver must have been on duty for 48 hours
for an employer to deduct sixteen total sleeping hours from
compensation (and, presumably, applying the same pattern for
each subsequent 24-hour period).   As we explain, we agree with
the Department of Labor's underlying premise that a driver's
sleeper berth time is compensable "on-duty" time, and we do not
pass on here the Department's assessment of how to calculate
additional periods of excludable sleep time beyond the initial
24-hour period.

As such, the pre-2019 letters are entitled to respect.19                      We

therefore    read   § 785.22    with   § 785.41      to   conclude   that    the

eight-hour    cap   applies    to   time    spent    riding   in   the   sleeper

berth.

                                     III.

             Based on our application of the predominant benefit

test and the DOL regulations at issue, we hold that employees'

time spent in the sleeper berth that exceeds eight hours per day

is compensable work under the FLSA.                 We therefore affirm the

district court's grant of summary judgment for Montoya on this

issue.

             So ordered.

    19  We also acknowledge that the Secretary of Labor's
briefing in this litigation, advocating for the compensability
of sleeper berth time exceeding eight hours, is consistent with
the DOL regulations and the WHD's longstanding position.
