So im being put on a PIP (Performance Improvement Plan) at work...not a good sign

I'm sorry, but i personally feel like the person that trained me is terrible at it. Have i made some mistakes on my behalf? Sure, thats going to happen if you been on the job for less than a year. My trainer talks and talks and talks and gets a rise out of embarrassing me and being condescending. If this PIP doesnt work out, then screw it. Itll have to find something else to do with my life at 34 years old
