There is no limitation on the total accumulation. Part time employees earn the same amount of sick leave.
Sick leave can be used as soon as it is credited to the employees account.
In addition, under certain circumstances a limited amount of sick leave can be used to care for a family member or to make arrangements for or attend the funeral of a family member and for other related purposes. Sick leave should be conserved for serious illnesses. Employees who are too ill to report for duty should notify their supervisor or designated alternate within the time limit specified by the agency. The duration of the expected absence should be given if possible. If the illness exceeds the original estimate, the supervisor should be advised when the employee expects to return to duty.
