I have stats off, paid. 10 calendar days of holidays, paid. And 4 personal/sick days, paid. All of this during the calendar year.
My rates are very reasonable, and it is the norm around here. The only time I wouldn't charge a family the usual rate is if they had just started that month or so, and I was taking a week off or some such thing. I would pro-rate for that time, for that family.
When you work out what we get paid on an hourly basis, I think that this is more than fair.
