Yeah, not all unions are created equal. We saw some of thst with the Hollywood strikes last year. That's sadly a part of why some anti-union sentiment spreads organically; if the people who are supposed to be looking out for your interest end up being another corporation to fight, what's the point?
That doesn't mean collective bargaining can't work. Especially for critical jobs like medicine and teaching. But it falls back to the issues of sole people not being at wits end and needing to be at wits end before going nuclear, instead of seeing the long term and being able to withstand short term sacrifice.
"vote", sure. Many countries vote for their leaders too. I think small groups like a single company have it worse because at least in some ways a nation wide election will somewhat represent the state of the country. The turnout for a union rep must be awful
Sometimes intentionally. I remember the SAG talks last year "voting" on a compromise and so many people not even realizing there was a meeting.
