Hypothetical question

I'm in a difficult situation in Nevada and trying to figure out my next steps.

supervisor making racist comments. I've been dealing with this for about 5 months now and the situation isn't improving.

I have worked at this company for 11 years. My position is exempt and I do not have a written employment agreement beyond the standard offer letter.

Has anyone been through something similar? What worked for you?
