Factory committees were workers' councils representing factory workers in the history of Russia and Soviet Union that accomplished workers' control in various forms. (In Russian language, the terms "zavod" & "fabrika" for factory are not synonymous: "zavod" is reserved for heavy industry and "fabrika" for the rest). Two basic meanings are to be distinguished.
Usage examples of "factory committee".
Say a worker came before a factory committee and pointed out that they were turning out cars with three wheels, or told a farm committee they were turning out calves with two heads.
Now it had come, surpassing his wildest dreams, but he, the born and faithful champion of the proletariat who had been among the first to set up a Factory Committee in the Sviatogor Bogatyr, and to hand the place over to the workers, had been left high and dry.
