Our time is awarded on an annual basis. At the start of each year, we get 5 sick days, 5 personal days and however many vacation days you are entitled to based on your years of service. We can carry over unused sick days up to a limit of 25. At that point, any unused sick days at the end of the year above 25 are bought back at 75%. Unused personal days are bought back at the end of the year at 100%. The only time we can buy back unused vacation days is when you separate service, typically at retirement.
Along these same lines, how much annual and sick leave do you all accrue per pay? With my time in grade, I get 12.92 hours of AL per pay, 6 hours of SL, and 9 hours of comp leave (no overtime for me).
