Your post makes it sound like you had no idea there was a case with the EEOC from back in July. But how could that be? You would have had to file a complaint with the EEOC for that to happen. Perhaps the EEOC caseworker confused you with someone else that had filed a complaint. Something is amiss there.

If the employer terminated you because you filed a complaint with the EEOC that would be wrongful termination. However, it does not appear that you have any evidence to suggest that is actually the reason you were fired.

I suggest you consult an attorney who litigates employment discrimination and wrongful discharge claims in your state. (You did not mention the state and that matters because only a lawyer licensed in your state will be able to help you.) Most lawyers that handle those kinds of cases will give you a free initial consultation, so you shouldn’t have to pay anything to find out if you might have a good case to pursue.
