David Harsanyi, The Federalist
How does a public-sector union work? Easy.First, the state creates a monopoly. The monopoly forces taxpayers to fund those workers, whether they do a good job or not. The union then coerces workers to pay dues regardless of whether or not they want to. Then the union uses those dues to help fund political advocacy that perpetuates their monopoly and the union’s influence. So, in other words: racketeering.
