A company can chose to not negotiate or hire a union, or can chose to have the union be the labor supplier. The company choses to sign contracts, or not. This is no difference than anyone who supplies iron ore, or oranges to a super market, or day care providers. The union supplies a service, labor. If the company doesn't like that supplier, they can hire others. This isn't often a good choice for the employer, (see Boeing and their issues moving production to North Carolina), but it is their choice to make.

Unions are a sign of a true free market economy, and I anticipate most of the objections brought up in this conversation, will be when the state screws the free market up. "right to work" laws, for example. Taft Hartley. Joe Biden screwing railway workers last year.
