May I call in sick after my supervisor has canceled my annual leave and ordered me to report for work?
An employee is entitled to use sick leave under certain conditions. However, under 5 CFR 630.403, an agency may grant sick leave only when supported by administratively acceptable evidence. If the supervisor does not grant the request for sick leave or any other leave, the employee maybe considered Absent Without Leave (AWOL). An agency may take disciplinary action against an AWOL employee, up to and including removal from Federal service. Also see discussion of leave flexibilities.
