Do you have a contract ? If you don't wrote one up ASAP. Put in there a full time spot opportunity will take over a part time or before and after school spots. Also that they have to pay for what was stated in your agreement wether they attend or not. I have it in my contract that people pay for the spot not by the days they attend. Otherwise you end up losing money or not ever knowing what you are going to make each month. Don't do favors for your clients like hours doing. They are taking advantage of your kindness. And 95% of the time parents will take advantage of whatever they can. Take the full time boys. Your family needs come first. Not those of parents that screw you over weekly.
