Calculating Sick Leave
For FERS and CSRS employees, unused sick leave counts as time served, but sick leave days are not a one-for-one conversion when calculating sick leave. You will need to reference the Credit for Unused Sick Leave Conversion Chart published by the Office of Personnel Management (OPM) to determine how many service days can be added to your calculation. The chart can be found online at opm.gov.
Due to the added complexity required to determine the amount of service days that could be added as time served, we created the video below to assist you in calculating sick leave.
