I published a book & legal training manual on this topic in 2009. Your employer is currently in violation of the law. You need to contact a worker's rights attorney TODAY. Given my experience in the field, if what you are saying is all factual, you could be in serious danger. Stalkers do not just stop "because someone told them to." They continue and they escalate. Your workplace is in violation of the law if they continue to employ this individual and he comes within 200 feet of you on their property. You ABSOLUTELY have a legal claim against them. You need to hire an attorney, who needs to draft a letter to your employer explaining the situation and demanding that this individual no longer work on the same premises as you. The second your employer hires their own attorney, they will be advised to comply IMMEDIATELY. You also need to contact the police and inform them that this individual still works at the same place you do and is violating the restraining order by coming within 200 feet of you (assuming he has done so after the order went into effect). I don't want to frighten you any more than you already are, but this is serious. This cannot continue to go on.
