You are paid for the Monday stat and what you do on that day is your choice. In effect you are only taking 4 days of vacation so if you have extra days left make yourself another long weekend in the summer somewhere. Just because you go away on your stat day off is no one's business anymore than weekends. Just word it to the parents that you are taking 4 days of your annual vacation time and that you are taking Monday July 2 in lieu of the Sunday Stat. Therefore the daycare will be closed from closing time Friday June 29 till opening time Monday July 9.
