Do not involve a lawyer; trust me I've been in your shoes and I was talking to a lawyer the brother of one of my ex's and even he told me it was a bad idea to involve a lawyer. Realistically he said there was very little he could do since my employment was at will; legally they could get away with firing you because you had booger hanging out of your nose. My best advice is to get those resumes out and get out of the current situation you are in.

Some states are even right-to-work and at will employment. Jobs just aren't as secure as they once were.
