I charage for stat holidays. Most parents are also paid for those days where they work. There are exceptions including those that work part time or do contract work so in the past I have let some of my part timers get away with not paying for ALL of the stats but still charged them for some of them. I don't take large blocks of holiday time so I take 10 paid stat days and parents have 10 days in the summer to use as unpaid holiday time so it evens out. PT people are prorated for days off unpaid so to some degree I prorate the stats they pay for - but only if they whine or I really like them.
