Fighting against the man is always anti authoritarian, and that’s a big part with them, too, obviously. I honestly think if you set the bar at a union that wants to abolish capitalism (add in the blanks what that means), then you’ll not be pressuring & negotiating with the bosses, but couping. Or something like that. That’s a different game, isn’t it?

Anarchism != not being organized, and strategising, learning how to talk to coworkers to organize and mobilize them, can be applied in any context, be it a more hierarchical or a flat one, I’d say. They mostly focus on closed structures rather than elected groups (i.e. groups people just tend to be a part of, like an apartment building or employees to the same company vs rallying people for an anti-racism protest).

As for that they don’t organize any basic ones soon, just gives you more time to get people together or so, time flies (though that doesn’t help if you really need to get started asap). It’s worldwide & hugely inspirational and think it’s valuable for more & less mature groups alike.

Hope that helps!
