I'm in a bit of a position, which I need some advice on. These past two weeks my employers at the Airport have been asking me to take on extra hours. Since I make more there, than at School, I have been accepting. Last week I called my superviser at School and told her that I would be cutting my hours due to the hours I'm picking up at the airport. Friday the Airport informed me that I would be getting enough hours that I would more than cover what I am making at School. So, I decided to quit at School becuase I can work an additional 6 hours at the airport and make what I made in 11 hours at School. I planned on going in tomorrow and telling my boss at School. The airport just called me and asked me to cover for a call off tomorrow, starting at 7 am. I agreed. Here is the issue. I was supposed to work at the School from 10 till 12 tomorrow and then at the airport from 12:30 till 7:30. They asked could I work 7 am till 3:30 and then someone would cover my 3:30 to 7:30. The School opens at 8. Should I call now and leave a message, saying I won't be in and I quit. Or should I wait till I'm at work tomorrow and call around 8:30 when I know my boss will be there? And what precisely do I say? It's not a big deal, as it is merely Workstudy, but I don't want to be rude. Some kids just don't show up and never actually tell them they quit... I don't want to do that. So, how should I handle this?
