Q: If I retire Dec. 31, a Friday, my first annuity check would begin on Feb 1, 2011. However, I would lose credit for any leave accumulated in that last pay period because I did not work the full pay period, which ends Jan. 1, 2011. Is this correct? A: If Friday, Dec. 31, would be the last day of a pay period and you retire at the close of business, you would get credit for any annual and sick leave you earned during that pay period.
