I tend to agree with Bill in that you rise to the occasion and look to improve things. Try to find the best in the situation and improve things.

However, I don't like to be abused, and I have seen places that just look to abuse people. And people that put up with it, often because they are afraid of losing their jobs. I won't do anything unethical, and while I'll work the extra hours in the short term, a week or two, I won't do it permanently or for months. That's not worth it.
