Insurrectionists usually reject all anarchosyndicalism and some say they are "againts organization". On the other hand post-left anarchist and individualist anarchist Hakim Bey is a member of the IWW. He said that:
"Class-warfare may not suffice for us as an explanation of all reality, but obviously it is real — we know where our sympathies lie. We oppose the idea of the social construct “Work” — but we are far from opposing “the workers”. The alienation of labor, we feel, cannot be explained entirely by wage-system economics; it also has a psychological origin. This double critique throws the very concept & deep structure of “industrial work” into the crucible of radical deconstruction. Meanwhile however industrial work is real, & workers’ control must be considered a fully valid tactic toward realizing both the economic & the psychological aspects of any hypothetical “new society within the shell of the old.”...A “individualists” moreover we have good reason to appreciate the IWW concept of the union. Stirner — contrary to the belief of those who have not actually read his book — spoke approvingly of a “Union of Unique Ones” (we prefer this translation to “Union of Egoists”), in which all members would reach for individual goals through common interests. He suggested that the workers had the most to gain by embracing this notion, & that if the productive class were to organize on such a basis it would prove irresistible. (The prejudice against Stirner, by the way, can be traced to Marx & Engels, who considered him potentially even more dangerous than Bakunin, & wrote their biggest book to destroy his influence.)...The Mackay Society, incidentally, represents a little-known current of individualist thought which never cut its ties with revolutionary labor. Dyer Lum, Ezra & Angela Haywood represent this school of thought; Jo Labadie, who wrote for Tucker’s Liberty, made himself a link between the american “plumb-line” anarchists, the “philosophical” individualists, & the syndicalist or communist branch of the movement; his influence reached the Mackay Society through his son, Laurance. Like the Italian Stirnerites (who influenced us through our late friend E. Arrigoni) we support all anti-authoritarian currents, despite their apparent contradictions. Why? Because we feel that some realization of personal liberty is possible even in the very act of struggling for it. From our point of view, radical organizing (up to the point of insurrection) is not a sacrifice one makes to the future; it is rather a mode of self-liberation with its own immediate reward — even if that reward consists only of fragments & moments of realization. Wobblies, with their contempt for “pie in the sky someday” (or as Lewis Carroll put it, “Jam tomorrow or jam yesterday, but never jam today”), must feel the same distrust of any leftist utopianism which demands our martyrdom on behalf of a materialist “someday” which we ourselves will not live to see.""
