andie_nachgeborenen says, "Anarchists have historically opposed unions, or unions that they do not dominate like the IWW, and then tend to view contracts as class collaboration. These days, with formal recognition and contracts so hard to obtain, nonideological working class like WalMart workers have redis overhead the strengths of nonunion noncontract concerted action."
Do you have some evidence that the IWW was dominated by anarchists? Debs was a founder. Bill Haywood?
