The more union workers the better, whether they are Teamsters or members of another union IMO.

"I'd rather close my places and fire everybody and just retire and do something else with my money," said Moshe Winer, the owner of several car washes throughout New York City but not of Metro Car Wash. If wages and benefits for his workers went up to, say, $10 an hour, his profit margin would be too slim for him to keep operating, he said. He pays his workers at least minimum wage, Winer said, adding that while not everyone "plays by the rules," most of the city's other car wash owners pay above minimum wage, too.
