It's just different wherever you work, I suppose. For example, if I work 40 hrs/week for 2 weeks without taking a personal/sick day my check comes out to be $800. But if I were to take one sick day and one personal day, my check would come out to be $700-something. I still get paid for those days I was out, but not as much as I would get paid if it was a regular 8 hrs day. It's weird.
