The problem exist for corporations as well. A teenage girl, who was a former classmate and friend of my daughter, was murdered at work because she turned down a man's advances. She made formal complaints, but the bureaucratic corporate processes made it difficult to protect her or sufficiently separate her from the harasser/murderer. Even if the state is an at-will state, corporate policies and mismanagement often handcuff those involved to rectify situations before they get out of hand.
