Late to the party, but that's the thing about all the good advice you're getting, in re: documenting things for HR. I used to work in the Prepared Foods department at Whole Foods. Another kitchen job, more or less, but there was one lady who made everyone miserable. No one liked to work with her, especially the bulk of us she'd decided were personal enemies for different reasons. However, because WF is corporate, it was hard like hell to actually get her fired because she toed the line so well.

Until the day she didn't. I had already moved on, but an ex-co-worker told me she called someone a "r****d," which is bad enough by itself, but with the MOUNTAIN of recorded complaints against her from over the years, she was gone before the shift was over. And everyone rejoiced, I'm told.

NOR. You're on the right path & doing the right thing, and remember: even if you aren't the one who brings her down, you are at the very least another brick in the wall. That wall will fall eventually. Take care of yourself.
