Unions are advocates and adversarial by default, because there's no cost to being so and plenty of benefits.

In addition, the union doesn't care about one unit of workers. They will happily sacrifice one store, or one industry, to further their goals - which may or may not be aligned with the workers.

Their actions and their rhetoric shows that's the case.

If workers agree to be a means to some other end then that's great. But most of them aren't smart enough or aware enough to understand this, from what it seems. Meet the new boss, same as the old boss.
