Well Crap...

Been working for about 3 weeks now and I'm just flabbergasted. At the interview I told them I start school and these are my hours etc. They wrote it down on my resume. Work was getting more and more annoying but now today takes the cake. I gave them my schedule again just to make sure they remembered. Yea far from it, because they wanted me just for orders and a fill in. I have only 1 day next week and on that day we will "talk" about the future and what I think. I'm so agitated that I could beat someone. I don't know what to do anymore. I'm dome!
