As I write in my new book “The Hammer,” there are countless examples of unions that practice this principle well on state and local scales. The Culinary Union in Las Vegas has made hotel room cleaners and cooks into legitimate political power players by unionizing the entire casino industry, and then continuing to organize internally to keep members mobilized and ready to fight. Their parent union, Unite Here, does the same thing to varying degrees in cities around the country. After all, if you organize the workers at the airports and the stadiums and the hotels and the convention centers, you have your hands wrapped around the throat of any tourist city’s vital economic organs.
