I filed a sexual harrassment complaint with my employer concerning another female employee. The company did not do a complete investigation, I have written proof of this, and I was fired for filing a false document (my complaint has merit, I have letters from other employees verifing it). I had previously been on a last chance notice for filing a false document, which I did not do, but I had to sign it to get my job back. Can the employer legally fire me for that even if it was under protected conduct? The company lost all their unemployment appeals, and they withdrew from their last appeal attempt before an ALJ.
