Sunds like my last job, about 4 years ago. They were the reason I couldn't go to work for anybody else for a number of years... I was afraid that anything that went wrong would be balmed on me. I got blamed for other people's idiocy all the time! I can't tell you how many times I got accused of screwing up a project because the PROJECT MANAGER mis-measured, mis-ordered, and sent out the wrong guys for the job! Somehow it MY fault that I didn't force a bully into doing his job. They used to joke that loads of people left my position and had nervous breakdowns. Seriously, they LAUGHED and JOKED about it!

Looking back, it wasn't worth the monthly salary. Nothing is worth being treated like that. Get out while you can to save your own sanity. You'll find a job, sooner or later. Be fresh for it, don't go in thinking of the misery you experience now.
