Mamdani: The city is many things. It is the global capital of business and technology. It is the home of the best pizza in the world—the best music in the world, the best theater in the world. But above all else, New York City is a union town. There is no New York City without unions. Across the world, when people think of our city, they think of greatness. And when they think of that greatness, whether they know it or not, they are thinking of the power of organized labor. When they think of towering engineering marvels like the Empire State Building, they are thinking of the union steelworkers and bricklayers that built it into the clouds. When they fly halfway across the world to see a Broadway show, they benefit from unionized flight attendants, baggage handlers, and airport cleaners at JFK and LaGuardia—union hospitality workers at our hotels, and union actors and stagehands that make magic happen on that stage. And when they think of a city where greatness is an everyday expectation, they too are thinking of the city workers that power this incredible place we call home. The school teachers who teach our children. The New Yorkers who drive our buses and subways. The ones who clean our streets and tend to our parks. Each and every one of those New Yorkers is in a union.
