IWW is a different kind of union. You're thinking of trade unionism. IWW is more syndicalist, and typically is focused on building community to empower its members and other workers rather than negotiating directly with bosses. Where trade unions silo workers into separate unions based on the type of work, the IWW sees that as a way of fragmenting workers' power and making it easier for the bosses to play one group of workers against another - the IWW is built on a "One Big Union" idea that organizes ALL workers that are not part of the manager and boss classes.

That can look a lot of ways, like encouraging bottom-up direct action over top-down calls for strike organization. Or the "Wobbly Shop" model, where workers elect their own managers. The IWW has been known to assist with people forming worker-owned cooperatives, and does prison inmate organizing through IWOC (its "Incarcerated Worker's Organizing Committee").

I get it, but I think the idea here is supposed to apply to everyday commissions too.
