I've been at the job for about seven years now out of college and have dealt with many managers with many different personalities just fine. But, my current manager is making my life very difficult because he sits around and waits for me to make a mistake so he can play a gotcha game with me (whether or not I actually made a mistake). I've actually been warned. By another member of management that my current manager has complained about me and that he is just looking for sticks to beat me with. He picked on another rep until he was fired before me and I think he's repeating the same pattern with me. I will tolerate a great deal but the other day I actually had to take a sickday where I was getting emergency medical care and the pain in the neck manager was still harassing me even after I called out sick and was actually getting my emergency medical care. I was tipped off again thwt he was planning a surprise sneak attack field visit with me that day and was pissy because it didn't go the way that he had planned. I've never been one to go to HR but I am considering it because thus is starting to take a toll on my health. Does anyone have any advice or tips for dealing with this truly unkind person? Thanks for any help in advance.
