Sick leave into annual leave

Q. I am a FERS employee with 32 years of service credit. I’m planning to retire on 6/30/14. I’m going to have around 480 hours of sick leave when I retire. Since you only get credit for a full month, I will lose around 130 hours. My HR person told me that I could get supervisor approval to change my sick leave to annual leave, not exceeding a total equal to the annual leave that I have on the books. I had never heard of that so I asked for specifics, which she couldn’t provide. Is it possible to convert sick leave to annual leave? If so, how do you do it?A. You can’t. There is no provision in law or regulation that would allow one kind of leave to be converted to another.
