I'm talking like anywhere from an hour to three hours late, not just a few minutes. She has never called either and forgets to take her phone so I can't get hold of her. Maybe I'm stuck on principal and keeping one's word but I really stress out every time this happens. I told her from the beginning (and put it in writing), she had 3 chances - well, I've given her five and each time she says it will never happen again. Then it does. One time, she left at 1am and didn't return until 3am and never asked to leave - she just left. I feel taken advantage of and don't really know what to do about it. She gets a minimum of 18 hrs off/week. Your feedback is appreciated.
