Most definitely there is work that can be done within unions, we should be wherever the class struggle manifests itself. I was more cautioning against the tendency I’ve seen online and irl for some comrades to valorise unionism, thinking that forming a militant minority and attempting a hostile takeover of a union totally in thrall to a bourgeois political party is a worthy project to pour all your energy and resources into.

It’s the same as bourgeois parliament, there’s certain strategic reasons that make it a useful place to do some entryism under certain conditions, but shouldn’t be the be all and end all of our movement.
