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," she said.

"Well, if I pay you $100, what cut do the girls get?" he inquired.

"The house gets $80 and the girls get $20," the Madame replied.

Mightily offended at such unfair dealings, the man stomped off down the street in search of a more equitable shop.

His search continued throughout the night until finally he 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 asked.

"The girls get $80 and the house gets $20," said the Madame.

"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," he said.

"I'm sure you would, sir," said the Madame, ...gesturing to an unattractive old woman in the corner, " ...but Bertha here has seniority!"
