80 STAT. ]
PUBLIC LAW 89-554-SEPT. 6, 1966
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. § 5545. Night, standby, and irregular 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 mcludes— (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 180 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 Civil Service Commission, 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 G S 9, 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 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 and duty at night and on holidays with the employee generally being responsible for recognizing, without supervision, circumstances which require him 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 duty. Premium pay under this paragraph is determined as an appropriate percentage, not in excess of 15 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-9, by taking into consideration the frequency and duration of night, holiday, and unscheduled overtime duty required in the position.
