5 CFR 550.1002 - Compensatory time off for religious observances.
(a) These regulations are issued pursuant to title IV of Public Law 95-390, enacted September 29, 1978. Under the law and these regulations, an employee whose personal religious beliefs require the abstention from work during certain periods of time may elect to engage in overtime work for time lost for meeting those religious requirements.
(b) To the extent that such modifications in work schedules do not interfere with the efficient accomplishment of an agency's mission, the agency shall in each instance afford the employee the opportunity to work compensatory overtime and shall in each instance grant compensatory time off to an employee requesting such time off for religious observances when the employee's personal religious beliefs require that the employee abstain from work during certain periods of the workday or workweek.
(c) For the purpose stated in paragraph (b) of this section, the employee may work such compensatory overtime before or after the grant of compensatory time off. A grant of advanced compensatory time off should be repaid by the appropriate amount of compensatory overtime work within a reasonable amount of time. Compensatory overtime shall be credited to an employee on an hour for hour basis or authorized fractions thereof. Appropriate records will be kept of compensatory overtime earned and used.
(d) The premium pay provisions for overtime work in subpart A of part 550 of title 5, Code of Federal Regulations, and section 7 of the Fair Labor Standards Act of 1938, as amended, do not apply to compensatory overtime work performed by an employee for this purpose.
