In the late 1960s, radical Black workers organized union caucuses in opposition to both their employers and the union bureaucracy—turning to Marxism and Black nationalist politics to guide their actions. The most significant of these caucuses was the Detroit-based Dodge Revolutionary Union Movement (DRUM). DRUM was formed out of wildcat strike at Chrysler's Dodge Main plant in May 1968. The Black militants of DRUM understood that political power flowed not from “the barrel of a gun,” as the famous Maoist saying had it, but from control of production in a capitalist economy. This talk will tell their story and draw out the lessons of this movement.
