A dedicated shop steward was at a convention in Las Vegas and decided to check out the local brothels. When he got to the first one, he asked the madame, "Is this a union house?"

"No, I'm sorry, it isn't," said the madame. "Well, if I pay you $100, what cut do the girls get?" he asked. "The house gets $80 and the girl gets $20." Mightily offended at such unfair dealings, the man stomped off down the street in search of a more equitable shop. At the second one, he asked the madame, "Is this a union house?"

"No, I'm sorry, it isn't," said the madame. "If I pay you $100, what cut do the girls get?" he asked again. "The house gets $80 and the girl gets $20." Again offended, the man stomped off down the street in search of a more equitable shop. His search continued until he finally reached a brothel where the madame said, "Why yes, this is a union house."

"And if I pay you $100, what cut do the girls get?" he questioned. "The girls get $80 and the house gets $20." "That's more like it!" the man said. He looked around the room and pointed to a stunningly attractive redhead. "I'd like her for the night."

"I'm sure you would, sir", said the madame while gesturing to a grotesque woman in her seventies in the corner, "but Ethel here has seniority."
