Is your lawyer an employment law attorney? If not, you also need an employment law attorney. Your company is in violation of the law by continuing to employ him in the same building. And yes, if he do much as bumps into you in the corner, call thyour police. Then file another complaint with HR. Then call your employment law attorney. But, honestly, the company should fire him before you go back to work. I don't know what your lawyer is doing, but he or she is not doing a competent job if this guy is still employed there. It's a MASSIVE lawsuit waiting to happen. I would also probably initiate a lawsuit right now against your employer for negligence and unsafe working conditions and intentional infliction of emotional distress. Just imitating the lawsuit should be enough to get them to fire this guy. But you need an employment law attorney, not just any attorney.
