I'm not sure I understand #2. Today, workers can switch unions with a vote, right? If the argument is that the workforce at any given company should be represented by an arbitrary number of unions... I'd have to give that some thought, but it sounds like something that would occur in a post-scarcity science fiction world (a dystopia, or perhaps just an anti-union parody) wherein the future workforce consists almost entirely of lawyers. Maybe it wouldn't be that bad.
