How does Sick Leave work for retirement calculations ...

leave on the books when I retire, I get 1 month added to my FERS time, right? WRONG. For purposes of retirement, OPM requires you to cash in your sick leave for WHOLE months, not just WORK DAYS of the month. For OPM, a month is equal to 30 days. So, you have to use your sick leave to buy back 30 days to get credit for just 1 month. Confusing? ................
