AFAIK The USA is one of the most anti-union non-authoritarian countries for a very long time. In other countries people receive a lot more support and protections for the right to organize

what’s your evidence for that?

It that’s true, why is union membership declining? why did Trump et al gut the NLRB? why do starbucks unionized employees STILL not have a contract years after forming a union?

Unions are good and we need more of them.
