Hypothetical question

On mobile so apologies for formatting. I'm in a difficult situation and trying to figure out my next steps.

severance offer seems low. I've been dealing with this for about 11 months now and the situation isn't improving 🤷.

I have worked at this company for 4 years. My position is non-exempt and I do not have a written employment agreement beyond the standard offer letter.

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