Wow, this went down hill fast. Too coincidental to me. If you haven't already, start writing all this down in case you end up needing it for legal proceedings.

Better check into what keeps them on the hook for unemployment benefits before you quit. Unless you have left something out or mis-represented any of this, I think you have a pretty good case (at least better than most we hear about). If nothing else, it could make an interesting story for your local news to pick up on.

This whole thing could have been avoided had the manager been a bit more civil.
