I'm going to avoid a special needs man and his family at work
Why do you want to avoid him? Is he annoying you?
He makes me uncomfortable by staring at my breasts. Is that reason enough?
I can understand why that kind of behavior would make you uneasy. He's probably harmless, but it couldn't hurt to talk to someone in the HR department.
I am going to have him fired.
Maybe you have some misunderstandings? You don't need to go to extreme and get him fired. As I said talk to someone in HR and they'll decide what to do about it.
