Depressed about work?

I work in a restaurant. It is never easy dealing with the lack of training and the moods of the management. The restaurant that I work at now is really good though. There is always going to be problems with your work and a manager will never be totally satisfied with you. I advise you to stick with it. If the problems don't get better in the next couple weeks than I would seek other employment. There are not too many jobs right now so if i were you i would stay with that job until I knew for sure than another would be available to me. Keep working and make sure you put school first.
