FYI no reasonable lawyer is going to take a constructive dismissal or defamation claim for this case, like some aggressive commenters are instructing people to do.

These aren't winnable claims. If a lawyer did take your case and start billing you for it, they're just milking you for cash until the inevitable dismissal.

This is why the "I'm not a lawyer, but" advice on the internet isn't as benign as it seems. It gives some people false ideas about what lawyers can do for them which leads to a lot of wasted time talking to lawyers at best, or a lot of wasted money on a dead-end case at worst.
