Previously, I didn't charge for summers off and holidays for the kids of teachers. I figured i was always lucky to find other kids who needed summer only care, so i would get paid anyway. When i did my contract overhaul, i changed that policy to 50% payment for vacations and time off. One family had no problem with it at all, and the teacher parent even said- and i quote- "hey i have no problem paying you half rate for the summer, i am securing my spot for the fall! Besides, if i get paid for the summer off then so can you" LOL. i just smiled politely and said 'thank you so much for your support and understanding.'
