5 U.S.C. § 6337: Accrual of leave

the term “paid leave status under subchapter I”, as used with respect to an employee, means the administrative status of such employee while such employee is using sick leave, or annual leave, accrued or accumulated under subchapter I; and the term “transferred leave status”, as used with respect to an employee, means the administrative status of such employee while such employee is using transferred leave under this subchapter. the maximum amount of annual leave which may be accrued by an employee while in transferred leave status in connection with any particular medical emergency may not exceed 5 days; and the maximum amount of sick leave which may be accrued by an employee while in transferred leave status in connection with any particular medical emergency may not exceed 5 days. shall be credited to an annual leave or sick leave account, as appropriate, separate from any leave account of such employee under subchapter I; and shall not become available for use by such employee, and may not otherwise be taken into account under subchapter I, until, in accordance with subsection (c), it is transferred to the appropriate leave account of such employee under subchapter I. as of the beginning of the first applicable pay period beginning after the date on which the employee’s medical emergency terminates as described in paragraph (1) or (2) of section 6335(a); or if the employee’s medical emergency has not yet terminated, once the employee has exhausted all transferred leave made available to such employee under this subchapter. any leave accrued but not yet transferred under this section shall not be credited to such employee; or if there remains, as of the date the emergency so terminates, any leave which became available to such employee under paragraph (1)(B), such leave shall cease to be available for any purpose. Nothing in this section shall be considered to prevent, with respect to a continuing medical emergency, further transfers of leave for use after leave accrued under this section has been exhausted by the employee.
