Unless of course you're in prison, which we aren't!.
I have definatley had some jobs that felt like I was though. There are a few companies I "did time" at before getting into this great trade.
I would not want to speculate too much, but you must have entered into some kind of contract or signed something that they slipped by you. I know when you haven't worked for a little while, you will not always read what you are signing.
Hope it works out for you.
