Hypothetical question

Looking for advice on a legal issue. Here's what happened.

competing offer triggered retaliation. I've been dealing with this for about 2 months now and the situation isn't improving.

I have worked at this company for 2 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?
