An agency must use the same minimum charge increments for weather and safety leave as it does for annual and sick leave under § 630.206.
Employees may be granted weather and safety leave only for hours within the tour of duty established for purposes of charging annual and sick leave when absent. For full-time employees, that tour is the 40-hour basic workweek as defined in 5 CFR 610.102, the basic work requirement established for employees on a flexible or compressed work schedule as defined in 5 U.S.C. 6121(3), or an uncommon tour of duty under § 630.210.
Employees may not receive weather and safety leave for hours during which they are on other preapproved leave (paid or unpaid) or paid time off. Agencies should not provide weather and safety leave to an employee who, in the agency's judgment, is cancelling preapproved leave or paid time off, or changing a regular day off in a flexible or compressed work schedule, for the primary purpose of obtaining weather and safety leave.
