I used to give full time parents 2 weeks no pay in the summer (July/Aug) and 5 days Sept - June which most used at Christmas. Now I have changed that to 10 days at half price in the summer and 10 days at half price in the winter. That way I still get some money and they get a break on fees when not here and it encourages tehm to keep the kids home when they have a day off as they save if they keep.
