But you are not charging her for a full week where she is only using 4 of the days are you? You are letting her come four days a week and pay your full-time daily rate. She shouldn't be able to just switch her days because a stat falls on one of her normal days. I would say you will let it go this time but in the future she will not be able to switch her days because of a stat (partly because you are full those days, but mostly because it isn't her regular day and if one of her regular days falls on a stat she has to pay for it with out a make-up day. I think the way your husband describes it is right on!
