International Union of Operating Engineers has sued Indiana’s governor, attorney general, and labor commissioner, asserting novel theories under which the state's right-to-work laws are slavery prohibited by the Thirteenth Amendment. First, the union is required to negotiate on behalf of all workers, regardless of what percentage of them have elected not to join the union. Okay, I at least understand why that one gets up their noses, even if I can't quite buy calling it slavery. But the second argument is that the law requires union workers to labor alongside non-union workers. If that's slavery, too, we've got a whole lot of restructuring to do.
What should we call it when taxpayers are forced to work to support other people? If we start calling it slavery whenever someone imposes a free-rider element on the system, let alone whenever we're forced to endure the company of people we disapprove of in public places, we're going to need a new word for real slavery. By this theory, the Jim Crow laws were an admirable anti-slavery measure.
