Labor and the Class Idea in the United States and Canada, by Barry Eidlin. Cambridge University Press, 2018.
Collective actors such as unions do not simply exist; they are formed and re-formed through social struggles. Moreover, to the extent that we can ascribe interests to classes, the mere fact that such a class interest exists in no way guarantees that members of that class will either be aware of it or mobilize in pursuit of it. Interests must be organized. In particular, it is parties and unions that do the work of organizing interests when it comes to creating something identifiable as “the working class.”
Good review in Labor Notes.
