You’re not entirely wrong. If there is a union, it exists because something bad has happened. People don’t just sit around and go “you know we should organize to protect ourselves from companies”. Companies thoroughly fvck people over then they organize to protect themselves.

Unions are the lesser of two evils between unionization and getting fvcked by companies.

You shouldn’t have to pay a mediating company to exist to make sure you get fair wages vacation and work, but it certainly didn’t come out of nowhere.
