I had to turn in all of my work into a central folder " just for audit reasons", and then my wonderful boss did a Jekyll and Hyde, and began gaslighting me the 3 weeks before. Canceled meetings or wanted to talk about the weather in them. Contradicted me in meetings when others backed me up and thought she was nuts for saying such stupid incorrect things contrary to ANYTHING I said.
Can't believe I didn't see it coming.
The worst, most callous evil people you will ever deal with, however, is HR once you are let go. The treat you like gum on the bottom of their shoes. Nothing was worse than the abusive HR sickos after boss said goodbye. I complained about a few of them specifically.
