Industrial Workers of the World. Glory days 1912-1940s. Popular, mostly No. American labor union which won the 8 hour workday. Strong ethic of voluntary cooperation, and mutual aid. Slogan: "An injury to one is an injury to all." Largely destroyed by offical brutality (FBI). The modern IWW is still inovative, and enjoying something of a resurgence as self-organizing advocates for those most pressed by the global economy. See iww.org.
