Union organizers need better opsec. Ideally, management shouldn't know the workers are talking union until they stage the first wildcat strike.
There is no reason workers should honor Taft-Hartley restrictions. Those not protected by the law have no moral obligation to obey it.
Just a word of caution. I do think it is about time for labor to organize in a big way, and to be frank, with tech people supplying the technical knowhow to implement the blueprints for C&C, I have a feeling if things do get as rowdy as they did at the peak of Labor's power last century, there will be an even more impressive fallout than ever seen before if escalation on either side gets out of hand.
