The pertinent question is about your company as a whole. If it wasn't for your manager would you be content to stay?

If "yes", then blacklist his number and never answer after hours. When asked to do something different always explain how that affects the other work in progress. Only work 8 hours or whatever you are contracted to do. If your manager kicks up a fuss, then go to the next level and/or HR. Refuse to be demeaned. Of course, you could get fired, but then your manager might get fired for his incompetence. It is a risk. But taking the "I don't give a F**! FAFO" attitude makes you feel more in control.

I speak from experience. I once had a managing director give me a hard time, I blew up on him and waited for what I thought was the inevitable termination. A week later, and most unexpectedly the firm's partners fired the MD.
