You’re welcome. Hopefully it’s helpful! It says something about the Wobblies/IWW, at least. If it doesn’t help, there’s this, too: https://libcom.org/article/syndicalism-introduction – can’t say I know too much about this org. Both links are a little obscure, though, as it’s not clear to me from either source what ideology underpins the org.

The IWW website says they accept all ‘workers’ but no employers; which makes some sense but creates a theoretical problem e.g. for: workers who are also managers; employers who work alongside their employees and are sub-contracting off the real ‘not-employer employers’; and ‘workers’ who run/manage temp agencies or sub-contracting firms. The internationalism suggests it’s a Trotskyist org but that doesn’t really align with these three example problems as I’d expect Trotskyists to have a more nuanced concept of class. Which suggests instead that it’s anarchist. According to the second link (the first one in this comment), the IWW represents ‘Industrial Unionism’, which is related but different to anarchy-syndicalism. Who ever said the left is divided? On top of that, the IWW is a union in the sense that it does not dictate a political line; all workers are welcome (subject to the above contradictions, which I have no idea how it resolves).

With this brief understanding, I can see how the IWW or its members could get embroiled in tricky situations, such as protecting reactionaries (although I wouldn’t want to guess and I’m not certain that it was the IWW who was accused of supporting cultural conservatives in your example).

It would be a lot easier if everyone who cared about life on planet earth just became an ML. Far less confusing, for a start, and they might be more effective.
