Its the reason I work basically alone at night. I don't have a Manager to deal with nore back stabbing co-workers. Isolated jobs like mine are hard to find. I hear stories of stuff that goes on during the day and I know I wouldn't make it cause someone would be punched Out!

My suggestion is take a tape recorder and demand HR be present when you ever meet with Management. Make sure you tell them you will be recording them. Get a Lawyer and find someone who can witness these actions!

Play it smart, don't let them get the better of you and good luck!
