I have a supervisor who's really riding me right now. He says that I'm too slow so he watches every single move I make and gives very annoying pointers and corrections to what I'm doing. I'm a PAS clerk who can't really type all that fast and he's not really that understanding of that fact. My union rep says that I can't grieve this but everyone else says that I can and tells me to go to another union rep and complain about harassment. Is this wise?
