I work on campus and recently I got a new different on campus job that is way better. I was supposed to start today but the lady to sign me up has been sick. I'm scheduled to work at my old job tonight but the problem is that the max I can work in a week at the school is 20hrs. If I goto my old job tonight I wouldn't be able to work for my new job later this week if the lady is not sick and they want me to come in because I'll have worked 16hrs already. But if I don't goto my old job tonight I'd be relying on the new job to turn out because the old job would be mad at me. Should I go tonight or not?
