None, it's all part of your accrued PTO. If you are sick, you have to use 8 PTO hours. Same with holidays, they force you to take the day off and use 8 hours of PTO. This policy makes it tough for new employees, very challenging when you relocated half way across the country to go back home and get more of your stuff for instance. I'm still not totally moved to the bay area 5 months later.

6 sick days per year. Very strict policy.
