One should not have to work for assholes.
Agree!
My former supervisor seemed to take a great deal of delight whenever she could show me when I was wrong, and she often drew out the time to teach me the right way to do it, if she even showed me the right way. More than once my error could not be replicated to show me the right way. I'm not sad not to be working there.
I can't say I blame you.
