(1) If the basic rate of pay of the employee is fixed on a basis other than an annual or monthly basis, multiply the basic hourly rate of pay by not less than one and one-half.

(2) If the basic rate of pay of the employee is fixed on an annual basis, divide the basic annual rate of pay by 2,087, and multiply the quotient by one and one-half.

(3) If the basic rate of pay of the employee is fixed on a monthly basis, multiply the basic monthly rate of pay by 12 to derive a basic annual rate of pay, divide the basic annual rate of pay by 2,087, and multiply the quotient by one and one-half. An employee subject to this subsection whose regular work schedule includes an 8-hour period of service a part of which is on Sunday is entitled to additional pay at the rate of 25 percent of his hourly rate of basic pay for each hour of work performed during that 8-hour period of service. For employees serving outside the United States in areas where Sunday is a routine workday and another day of the week is officially recognized as the day of rest and worship, the Secretary of State may designate the officially recognized day of rest and worship as the day with respect to which the preceding sentence shall apply instead of Sunday. Time spent in a travel status away from the official duty station of an employee subject to this subsection is not hours of work unless the travel (i) involves the performance of work while traveling, (ii) is incident to travel that involves the performance of work while traveling, (iii) is carried out under arduous conditions, or (iv) results from an event which could not be scheduled or controlled administratively. The first and third sentences of this subsection shall not be applicable to an employee who is subject to the overtime pay provisions of section 7 of the Fair Labor Standards Act of 1938. In the case of an employee who would, were it not for the preceding sentence, be subject to the first and third sentences of this subsection, the Office of Personnel Management shall by regulation prescribe what hours shall be deemed to be hours of work and what hours of work shall be deemed to be overtime hours for the purpose of such section 7 so as to ensure that no employee receives less pay by reason of the preceding sentence.

(b) An employee under the Office of the Architect of the Capitol who is paid on a daily or hourly basis and who is not subject to chapter 51 and subchapter III of chapter 53 of this title is entitled to overtime pay for overtime work in accordance with subsection (a) of this section. The overtime hourly rate of pay is computed in accordance with subsection (a)(1) of this section.

(c) The provisions of this section, including the last two sentences of subsection (a) and the provisions of section 5543(b), shall apply to a prevailing rate employee described in section 5342(a)(2)(B).

§ 5545. Night, standby, irregular, and hazardous duty differential

(a) Except as provided by subsection (b) of this section, nightwork is regularly scheduled work between the hours of 6:00 p.m. and 6:00 a.m., and includes

(1) periods of absence with pay during these hours due to holidays; and

(2) periods of leave with pay during these hours if the periods of leave with pay during a pay period total less than 8 hours.

Except as otherwise provided by subsection (c) of this section, an employee is entitled to pay for nightwork at his rate of basic pay plus premium pay amounting to 10 percent of that basic rate. This subsection and subsection (b) of this section do not modify section 5141 of title 31, or other statute authorizing additional pay for nightwork.

(b) The head of an agency may designate a time after 6:00 p.m. and a time before 6:00 a.m. as the beginning and end, respectively, of nightwork for the purpose of subsection (a) of this section, at a post outside the United States where the customary hours of business extend into the hours of nightwork provided by subsection (a) of this section.

(c) The head of an agency, with the approval of the Office of Personnel Management, may provide that

(1) an employee in a position requiring him regularly to remain at, or within the confines of, his station during longer than ordinary periods of duty, a substantial part of which consists of remaining in a standby status rather than performing work, shall receive premium pay for this duty on an annual basis instead of premium pay provided by other provisions of this subchapter, except for irregular, unscheduled overtime duty in excess of his regularly scheduled weekly tour. Premium pay under this paragraph is determined as an appropriate percentage, not in excess of 25 percent, of such part of the rate of basic pay for the position as does not exceed the minimum rate of basic pay for GS-10 (including any applicable localitybased comparability payment under section 5304 or similar provision of law and any applicable special rate of pay under section 5305 or similar provision of law) (or, for a position described in section 5542(a)(3) of this title, of the basic pay of the position), by taking into consideration the number of hours of actual work required in the position, the number of hours required in a standby status at or within the confines of the station, the extent to which the duties of the position are made more onerous by night, Sunday, or holiday work, or by being extended over periods of more than 40 hours a week, and other relevant factors; or

(2) an employee in a position in which the hours of duty cannot be controlled administratively, and which requires substantial amounts of irregular, unscheduled, overtime duty with the employee generally being responsible for recognizing, without supervision, circumstances which require the employee to remain on duty, shall receive premium pay for this duty on an annual basis instead of premium pay provided by other provisions of this subchapter, except for regularly scheduled overtime, night, and Sunday duty, and for holiday duty. Premium pay under this paragraph is an appropriate percentage, not less than 10 percent nor more than 25 percent, of the rate of basic pay for the position as determined by taking into consideration the frequency and duration of irregular, unscheduled overtime duty required in the position.

(d) The Office shall establish a schedule or schedules of pay differentials for duty involving unusual physical hardship or hazard. Under such regulations as the Office may prescribe, and for such minimum periods as it determines appropriate, an employee to whom chapter 51 and subchapter III of chapter 53 of this title applies is entitled to be paid the appropriate differential for any period in which he is subjected to physical hardship or hazard not usually involved in carrying out the duties of his position. However, the pay differential

(1) does not apply to an employee in a position the classification of which takes into account the degree of physical hardship or hazard involved in the performance of the duties thereof, except in such circumstances as the Office may by regulation prescribe; and

(2) may not exceed an amount equal to 25 percent of the rate of basic pay applicable to the employee.

The Office of Personnel Management may prescribe regulations to carry out this subsection.
