Please don't waste your time and emotional energy documenting the abuse or bother going to HR - 7 out of 10 people who report bullying to HR lose their job. And I know this firsthand, having had it recently happen to me. HR is there to protect the company, not the employee, and once it's been determined you're no longer drinking the Kool-Aid and being a good little employee, they will find a way to eliminate you.

Best bet: cut your losses and move on just as soon as you can. Don't wait until you go into a major depression as I did - that's how I found this board!
