The old form of trade union, which was born in the nineteenth century and aimed primarily at negotiating wages for a specific trase is no longer sufficient. First of all, as we have been argueing, the old trade unions are not able to represent the unemployed, the poor, or even the mobile and flexible post-Fordist workers with short term contracts, all of whom participate actively in social production and increase social wealth. Second, the old unions are divided according to the various products and tasks defined in the heyday of industrial production - a miners' union, a pipefitters' union, a machinists' union and so forth. Today, insofar as the conditions and the relations of labor are becoming common, these traditional divisions (or even newly defined divisions) no longer make sense and serve only as an obstacle. Finally the old unions have become purely economic, not political, organization.
