I don't think there's much you can do at a workplace sometimes. The best you can do is to let people know what your boundaries are and your expectations. That can be a problem because sometimes your manager doesn't care about what YOU need to work best. It's about them. I can remember a situation where I was responsible for a task every month and I explained to my coworkers "I need to follow this deadline, so I am asking for everyone to make their submissions no later than x date." Then I've have someone trying to bypass the deadline and when I wouldn't budge, they'd get a supervisor involved who'd of course go over me and tell me I needed to do it. I think quitting sometimes is the best course of action, but what happens when you can't quit because the job market is bad? You don't want to look like a job hopper either, so what do you do? It's so tough out there job wise, and I think that's why so many people are stressed out from their jobs.

I too, learned that the hard way. I stayed at jobs before for too long even when I knew they were unwilling to change. At least when you are married and you change, over time your spouse has to change in order to accommodate you. You live together after all, but the workplace is an entirely different animal. Some people can leave at the end of the day and don't care about what happened, but that was so difficult for me. When I left, I ended up taking some of work at home and it just made things worse.
