Legal Question in Civil Litigation in California

There is nothing illegal about sleeping with your married coworker, but there is nothing honorable about it either. You could apply for a court order protecting you from harassment, if you think that will help.

You can't 'protect' your job, but you could seek a Restraining Order against her making any such contacts. If serious about doing so, feel free to contact me for the legal help you'll need.

I agree that you can ask for a restraining order, but getting one won't be easy. A court ordinarily can't bar someone from communicating with third parties. Such an order would violate the restrained person's First Amendment rights. The court can order her to stop making specific statements to third parties, but only if those statements are false or violate your privacy. You haven't told us what the other woman has been saying, so I can't evaluate your chances.

I disagree with Mr. Hofman. It is relatively easy to get restraining orders of the kind you would need. He is right that it has to be narrowly taylored to protect your job, but that is not hard to do and is fairly common in cases like this where a person is seeking to get someone fired out of vengance. If you are in the greater San Francisco Bay Area or Sacramento, I would be happy to assist you.
