Leave.
1999- went to work at a firm... basically I felt in my gut I needed to leave. I nicely told them and offered to work for my last few weeks. They stiffed me on pay. I moved on. But 10 years later the guy in charge was arrested for crimes he committed at work.

2006 got a job I hated but made myself stay because I felt I ran too much. And got stuck working for an abusive boss... worst time of my life.
