I just found out about Rawick, a member of Facing Reality and theorist of working class self-organization and black liberation struggles. Here  he discusses worker self activity in struggle, and the problem it posed for the traditional leftist ideas about struggle. I had never heard of any of the lesser players in Facing Reality so included him as a historical point for those interested in that.
