That is bizarre. An HR rep's job is to minimize the company's liabilities, not expand them.

I understand not shifting employee job functions based on an unproven accusation. If there's a restraining order in place, it's not her problem. It's his. He's restrained. He has to go to his HR rep and say "I can't legally work next to this person, what happens?"

That's only one side of the story, though.
