Pam worked as a security guard. The other security guards, all men, routinely verbally harassed her because she was doing a "man's work." Additionally, they would hide her badge and keys to the client's doors. Her uniform was greased and motor oil was poured inside her purse while it was in her locker. Pam complained to her supervisor who asked immediately if any of the men had ever touched her. When she said no, the supervisor said there was nothing he could do to stop it, that it was just horseplay.
