but what about the right to be free from retaliation?

I have a discrimination case against my employer, I already filed that with the ACRD, but this was an unemployment hearing. I gave notice of intent to resign because of the discrimination I was subjected to if my employer wouldn't attempt to remedy within 15 days (constructive discharge) and effective date of resignation was supposed to be June 2- but employer removed me from schedule entirely as of May 31, even though I had stated that June 2 was the 15th day and would therefore be my last if they offered no other remedy. Since I wasn't allowed to work until my resignation date became effective, then I was discharged. That was the fact that I was supposed to prove at that hearing and I did with evidence which I submitted. My employer had nothing but lies which he obviously couldn't substantiate, but nevertheless the judge said I resigned because I didn't send in the info to prove the discrimination; but I had read that retaliation was unlawful regardless of if the discrimination was , so for this proceeding, I focused on simply proving the fact that that I had unlawfully been retaliated against. I thought I had engaged in a protected activity period. I am now at a complete loss...
