"I'm sorry, Thera. But we've got to cut a few people, and you're one of them," Dr. Stanley sounded remorseful as he delivered Thera Johnson the devastating news. She was fired. With just three days left to pay her $600 rent, she had no job. All she needed was $250 more, but it seemed that wasn't going to happen.

I'll pay you twenty bucks for a couple of hours."

Thera thought about it for a moment. Twenty bucks wasn't much, but she really could use the money. But could she really do that kind of thing?
