I am being constantly followed around my place of business by a coworker. He has been doing this for a few months now. I have spoken with my superior, and she has spoken to him, but he is still following me around when I am alone in various parts of the building. Is there something that I can do about this legally or otherwise? I am very uncomfortable by this behavior that seems to have started of nowhere. I am concerned with what he might do, and I am afraid at this point that I will have to leave to get some peace.

Keep reporting it to your supervisor.

Thanks ScottGem for your speedy response.
