Are companies supposed to help unions form against them?
You're framing it as an inherently adversarial relationship. Owners of a company are allowed to coordinate, and do so by voting their shares to select directors and officers. Workers should be similarly free to organize in pursuit of their interests. In many cases, the interests of shareholders and labor will coincide because the workers understand a lot of things about the business that the shareholders (and indeed management in many cases) do not.
