I was there for 19 years, If a supervisor or any upper management has any issues with you and they want you out, eventually they will win and get you to either quit or get fired. I had a supervisor talk poorly bout me sent it in an email to me by mistake. When I called him out on it he then harassed me daily. Even when I went to a new supervisor he continued to harass, be little, and continued to be unprofessional to the point of where I finally gave in and quit. Some people say why let him win, but when its a everyday occurrence and he is your direct supervisor it wears on you after awhile. It got ro the point where I no longer enjoyed my job and dreaded coming to work evereyday.
