Workplace Discrimination - Gender Pay Gap

Has anyone dealt with something like this? I'm not sure what my options are.

remote worker being told to relocate or resign. I've been dealing with this for about 2 months now and the situation isn't improving.

I have worked at this company for 11 years. My position is non-exempt and I do have a written employment agreement beyond the standard offer letter.

Do I have a strong case? What should my next steps be?

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
