I know that this idea would be almost completely impossible to carry out, and i don't know if this is aöready a thing/an idea that is common, if it would work, etc., but i just want some thoughts on this idea.
What if there was an organization in America or any other country where, any adult can sign up for this organization, and it would be completely free to join and have no direct downside for the time being. The goal of the organization would be to achieve a membership of something around 50% of the population, so it would have to be massive and have widespread support, but let's assume it somehow gets this. The point would be to make a set of demands to the corporations in the area, such as, higher pay, no price raises as a result of it, certain workers rights things, etc. The only thing that the people who sign up for this union have to do is completely boycott any work on command if companies do not do what they say. Obviously, 50% of the population striking would be hugely devastating and pretty quickly destroy these companies financially, and they would have absolutely no choice but to comply. If this goal was somehow achieved, it would solve everything. Obviously this would be nearly impossible to achieve, but I'd just like to hear any thoughts on it.
Obviously I'm aware unions already exist, but I'm more focusing on th idea of a much more large scale one and what would happen if it formed.
