I'm a salaried employee, and like LT's H, I get a set number of days per year for paid time off (PTO). I use those for vacation or sick days. I earn a certain number of PTO hours per pay period, so when I started the job I had zero hours available and couldn't use any until I earned them. At certain milestones, you get more days per year. I'm approaching my 5 year anniversary and will get an increase from 3 weeks PTO to 4 maybe, I'm not sure. Oh and you have to use 80 hours a year or you lose those hours, so it's an incentive to take some time off.
