                    TITLE 5--ADMINISTRATIVE PERSONNEL
 
                CHAPTER I--OFFICE OF PERSONNEL MANAGEMENT
 
PART 550--PAY ADMINISTRATION (GENERAL)--Table of Contents
 
                         Subpart A--Premium Pay
 
Sec. 550.112  Computation of overtime work.

    The computation of the amount of overtime work of an employee is 
subject to the following conditions:
    (a) Time spent in principal activities. Principal activities are the 
activities that an employee is employed to perform. They are the 
activities that an employee performs during his or her regularly 
scheduled administrative workweek (including regular overtime work) and 
activities performed by an employee during periods of irregular or 
occasional overtime work authorized under Sec. 550.111. Overtime work in 
principal activities shall be credited as follows:
    (1) An employee shall be compensated for every minute of regular 
overtime work.
    (2) A quarter of an hour shall be the largest fraction of an hour 
used for crediting irregular or occasional overtime work under this 
subpart. When irregular or occasional overtime work is performed in 
other than the full fraction, odd minutes shall be rounded up or rounded 
down to the nearest full fraction of an hour used to credit overtime 
work.
    (b) Time spent in preshift or postshift activities. A preshift 
activity is a preparatory activity that an employee performs prior to 
the commencement of his or her principal activities, and a postshift 
activity is a concluding activity that an employee performs after the 
completion of his or her principal

[[Page 496]]

activities. Such activities are not principal activities as defined in 
paragraph (a) of this section.
    (1) (i) If the head of a department reasonably determines that a 
preshift or postshift activity is closely related to an employee's 
principal activities, and is indispensable to the performance of the 
principal activities, and that the total time spent in that activity is 
more than 10 minutes per daily tour of duty, he or she shall credit all 
of the time spent in that activity, including the 10 minutes, as hours 
of work.
    (ii) If the time spent in a preshift or postshift activity is 
compensable as hours of work, the head of the department shall schedule 
the time period for the employee to perform that activity. An employee 
shall be credited with the actual time spent in that activity during the 
time period scheduled by the head of the department. In no case shall 
the time credited for the performance of an activity exceed the time 
scheduled by the head of the department. If the time period scheduled by 
the head of the department for the performance of a pereshift or 
postshift activity is outside the employee's daily tour of duty, the 
employee shall be credited with the time spent performing that activity 
in accordance with paragraph (a)(2) of this section.
    (2) A preshift or postshift activity that is not closely related to 
the performance of the principal activities is considered a preliminary 
or postliminary activity. Time spent in preliminary or postliminary 
activities is excluded from hours of work and is not compensable, even 
if it occurs between periods of activity that are compensable as hours 
of work.
    (c) Leave with pay. An employee's absence from duty on authorized 
leave with pay under subchapter I of chapter 61 of title 5, United 
States Code, during the time when he would otherwise have been required 
to be on duty during a basic workweek (including authorized absence on a 
legal holiday, on a nonworkday established by Executive or 
administrative order, and on compensatory time off as provided in 
Sec. 550.114) is deemed employment and does not reduce the amount of 
overtime pay to which the employee is entitled during an administrative 
workweek. Leave of absence with pay under subchapter I of chapter 61 of 
title 5, United States Code, is charged only for an absence that occurs 
during a basic workweek.
    (d) Leave without pay. (1) For a period of leave without pay in an 
employee's basic workweek, an equal period of service performed outside 
the basic workweek, but in the same administrative workweek, shall be 
substituted and paid for at the rate applicable to his basic workweek 
before any remaining period of service may be paid for at the overtime 
rate on the basis of exceeding 40 hours in a workweek.
    (2) For a period of leave without pay in an employee's daily tour of 
duty, an equal period of service performed outside the daily tour, but 
in the same workday, shall be substituted and paid for at the rate 
applicable to his daily tour of duty before any remaining period of 
service may be paid for at the overtime rate on the basis of exceeding 8 
hours in a workday.
    (e) Absence during overtime periods. Except as provided by paragraph 
(a) of this section, as expressly authorized by statute, or to the 
extent authorized while the employee is in a travel status, a period is 
counted as overtime work only when the employee actually performs work 
during the period or is taking compensatory time off as provided in 
Sec. 550.114.
    (f) Night, Sunday, or holiday work. Hours of night, Sunday, or 
holiday work are included in determining for overtime pay purposes the 
total number of hours of work in an administrative workweek.
    (g) Time in travel status. Time in travel status away from the 
official duty-station of an employee is deemed employment only when:
    (1) It is within his regularly scheduled administrative workweek, 
including regular overtime work; or
    (2) The travel--
    (i) Involves the performance of actual work while traveling;
    (ii) Is incident to travel that involves the performance of work 
while traveling;
    (iii) Is carried out under such arduous and unusual conditions that 
the travel is inseparable from work; or
    (iv) Results from an event which could not be scheduled or 
controlled

[[Page 497]]

administratively, including travel by an employee to such an event and 
the return of the employee to his or her official-duty station.
    (h) Call-back overtime work. Irregular or occasional overtime work 
performed by an employee on a day when work was not scheduled for him, 
or for which he is required to return to his place of employment, is 
deemed at least 2 hours in duration for the purpose of premium pay, 
either in money or compensatory time off.
    (i) Periods of duty that are compensated by annual premium pay under 
5 U.S.C. 5545(c) (1) or (2) shall not be credited for the purpose of 
determining hours of work in excess of 8 hours in a day.
    (j) Official duty station. An agency may prescribe a mileage radius 
of not greater than 50 miles to determine whether an employee's travel 
is within or outside the limits of the employee's official duty station 
for determining entitlement to overtime pay for travel under paragraph 
(g) of this section except that--
    (1) An agency's definition of an employee's official duty station 
for determining overtime pay for travel may not be smaller than the 
definition of ``official station and post of duty'' under the Federal 
Travel Regulation issued by the General Services Administration (41 CFR 
301-1.3(c)(4)); and
    (2) Travel from home to work and vice versa is not hours of work. 
When an employee travels directly from home to a temporary duty location 
outside the limits of his or her official duty station, the time the 
employee would have spent in normal home to work travel shall be 
deducted from hours of work.
    (k) Standby duty. (1) An employee is on duty, and time spent on 
standby duty is hours of work if, for work-related reasons, the employee 
is restricted by official order to a designated post of duty and is 
assigned to be in a state of readiness to perform work with limitations 
on the employee's activities so substantial that the employee cannot use 
the time effectively for his or her own purposes. A finding that an 
employee's activities are substantially limited may not be based on the 
fact that an employee is subject to restrictions necessary to ensure 
that the employee will be able to perform his or her duties and 
responsibilities, such as restrictions on alcohol consumption or use of 
certain medications.
    (2) An employee is not considered restricted for ``work-related 
reasons'' if, for example, the employee remains at the post of duty 
voluntarily, or if the restriction is a natural result of geographic 
isolation or the fact that the employee resides on the agency's 
premises. For example, in the case of an employee assigned to work in a 
remote wildland area or on a ship, the fact that the employee has 
limited mobility when relieved from duty would not be a basis for 
finding that the employee is restricted for work-related reasons.
    (l) On-call status. An employee is off duty, and time spent in an 
on-call status is not hours of work if--
    (1) The employee is allowed to leave a telephone number or carry an 
electronic device for the purpose of being contacted, even though the 
employee is required to remain within a reasonable call-back radius; or
    (2) The employee is allowed to make arrangements for another person 
to perform any work that may arise during the on-call period.
    (m) Sleep and meal time. (1) Bona fide sleep and meal periods may 
not be considered hours of work, except as provided in paragraphs 
(m)(2), (m)(3), and (m)(4) of this section. If a sleep or meal period is 
interrupted by a call to duty, the time spent on duty is hours of work.
    (2) Sleep and meal periods during regularly scheduled tours of duty 
are hours of work for employees who receive annual premium pay for 
regularly scheduled standby duty under 5 U.S.C. 5545(c)(1).
    (3) When employees are assigned to work shifts of 24 hours or more 
during which they must remain within the confines of their duty station 
in a standby status, and for which they do not receive annual premium 
pay for regularly scheduled standby duty under 5 U.S.C. 5545(c)(1), the 
amount of bona fide sleep and meal time excluded from hours of work may 
not exceed 8 hours in any 24-hour period. No sleep

[[Page 498]]

time may be excluded unless the employee had the opportunity to have an 
uninterrupted period of at least 5 hours of sleep during the applicable 
sleep period. For work shifts of less than 24 hours, agencies may not 
exclude on-duty sleep periods from hours of work, but must exclude bona 
fide meal periods during which the employee is completely relieved from 
duty.
    (4) For firefighters compensated under 5 U.S.C. 5545b, on-duty sleep 
and meal time may not be excluded from hours of work.
