I had a friend who wound up working with a miserable person for years. The company was decent but the person he worked for was the worst he had known in his entire career. I understand you are between a rock and a hard place here but do yourself a favor and try to find something else quick. Don't leave until you have another job lined up. Sit tight and smile through the pain knowing that soon you will move on. Even though you agreed to work there for another year, it is so not worth it to continue working with an individual like that. You don't want to be left with no self esteem, depressed and bitter (like my friend). Best of luck to you in the NEXT job.
