I had one job where I work up every morning wishing I was sick enough to go to the hospital so I wouldn't have to go to work.
At another job, I was working so many hours I was having trouble actually driving home at 2 or 3 Amam when I went home. Only job I ever quit without having another job, just physically couldn't take one more day and the final straw was when they asked me to do something unethical and illegal. Thanks to my exhaustion, I had a car accident in the parking lot the day I quit.
Other signs it's time to move on:
- You aren't sure if your paycheck will bounce or not
- You are part of a Death March
- The work is boring beyond belief
- You think someone is sabotaging you in terms of office politics - you start getting fewer responsibilities and less interesting assignments and Joe is getting the credit for the things you did and you are starting to see emails blaming you for things that someone else did.
- You simply can't live with the corporate culture
