BTW, no federal government employee gets anything called "personal days". Most smart employees save up their sick leave for that heartattack they're going to have in 30 years after listening to all this whining by private sector probate lawyers.
Are you with the Feds or collecting from your former job with them?
Personal days may mean different things to different people. The firm I know about switched from vacation and sick days off to personal days which covers both former sick and vacation days off. Personal days are not an addition but rather a combination of sick and vacation time off. The holidays remain the same. Bookkeeping is much simpler for that small business.
