Every company has its warts. If you don't have that much time invested here, I would advise you to go to swa. They are hiring gangbusters this year and for the forseeable future, so maybe you would be happier there. I don't have rose colored glasses about ups, but I get treated fairly well here and with the exception of one scheduler, T, who the rest of the schedulers hate as well, they are all cordial and professional.
Not sure how you got the "bitter taste" in your mouth, or how you have been "screwed", but I have the impression you work in the training center. If that is correct, I really don't see how you any reason to complain. If you work there, it's on a voluntary basis. Leave and go back full time to the line if you don't like how you are treated. I can assure you I have been treated very well here at ups. No job is perfect, but I am very happy here. If you are not, for your own sake, go somewhere else! Life is too short to do something you don't like no matter how much they pay you!
