Regrettably there is no present law against such treatment in the U.S.
Some states are considering workplace dignity laws that would allow such a claim, but there are none that have passed at this time.
The only way that you would have a claim is if you have a contract of employment stating that you can only be terminated for cause.
That would give you a legal right to your job and reasonable enjoyment of that job.
This harassment could be said to be a breach of that contract.
Without the contract though or an illegal motivation for the harassment, there is no legal recourse.
Do you have other questions or comments for me to consider?
Ok. Sorry that I can't give you a different answer.
