Good stuff!
A related issue is the idea of organized labor being the fight for legal union recognition. Lots of folks pour all of their energy into that fight and don't realize that they can do the walkouts (etc) and make gains without and before having a legal union. And, as the article notes, they can actually do even more, as they are not yet bound by any contract terms that favor the employer. It is actually very helpful to do this on the way to a legal union, as it builds confidence and a set of wins rather than the fairly common thing of 1-2 years of management stalling on the first contract or fucking around on challenging the union in bad faith. Nothing like a work stoppage, bad PR, and community support to bring them back to the table. And maybe the boss's Ferrari mysteriously gets scratched up who knows how that happened it must've been the wind.
