That is clearly too broad a brush. Collective bargaining is useful if your needs are aligned with the collective, if not they may be at best unhelpful and at worst actively counter productive (for instance if you have some personal circumstance you wanted to negotiate beyond the terms of the agreement, rather than negotiating with a boss or two you now have to negotiate with your representative organization). Not to mention various forms of corruption that can take hold in such arrangements.

I wonder if the rather abhorrent means of union busting has led to an extreme reaction of causing passer bys to take a cartoonish slant, as though unions can only do good in the world and only if they can overcome evil corporate interest. Unions have some clear advantages, but are far from a panacea of aligning interests for all parties.

This seems to me to be yet another fault line on which propagandists at the dials have managed to convince people to coalesce into tribes strong enough to use absolutist language where nuance is required.
