Pull an "Office Space". I am serious. Only go into the office when you feel like it. Do things that you enjoy, watch some kung-fu movies with your kids or whatever. It can take months to fire someone as long as you don't get into a fight, and you'll get severance. When your boss gives you shit about your work hours, literally tell him "Sorry, I have a meeting with the consultants" and leave for the day. You're talented, you'll get another job, and there is a decent chance you will not even be fired. They will let you work from home or in a different dept. after your boss complains about you to his boss.
