So I revised my contract last night and added a termination clause in there and added being late consistently as a reason to term.

I considered switching my hours to 445 but when I need to fill one of these spots I don't want to have to redo my contract again because most people need at least 5pm around here I find. This group knows that I am done at 430 and for the most part that is when they pick up.

Thanks for the advice! I am learning so much on this site lol
