If the workers' political party is a distillation of working-class experience, then industrial organisation is one form of concentration and ferment out of which the distillation takes place. Once the workers' political organisation has come into existence, leadership of the movement will tend to pass into its hands. General policies will tend to be determined by bodies that specifically set out to do so, rather than by those concerned in the first place with the problems of a single trade or industry. In South Africa this has very clearly been the case. Political tendencies have left their imprint on the industrial organisations of the working class. The political divisions that the state has drawn among workers extend to the industrial level as well.
