Which issue would be more likely to "stick" if I decide on legal action?
I'm not sure what you are asking. What issues do you mean?

If you want your situation reviewed in relation to your rights and remedies if this continues, or if it results in your termination, you should consult with a local plaintiff-side employment lawyer. A lawyer may be able to help you devise a plan to respond to your supervisor's conduct, and to help create the record you need to help win a claim against your employer in the event of wrongful termination.
