I was employed at a company partnered with another company - technically we were working under them. Someone not the company we were working under did not want me there anymore for and untrue issue, that I had witnesses to prove that were untrue. My HR said I was not allowed to go back since technically we work under the other company so I was offered a random position at a different location with my company that I declined because it was not what I was hired on to do or wanted to do. So they marked me as resigning even though I was forced out of my position I was hired on for. Since I was basically let go from the position I I loved, for reasons that were untrue, is this grounds for possibly winning a claim if I filed it against them?
