A workers' council is a form of political and economic organization in which a single place of work or enterprise, such as a factory, school, or farm, is controlled collectively by the workers of that workplace, through the core principle of temporary and instantly revocable delegates.
In a system with temporary and instantly revocable delegates, workers decide on what their agenda is and what their needs are. They also mandate a temporary delegate to divulge and pursue them. The temporary delegates are elected among the workers themselves, can be instantly revoked if they betray their mandate, and are supposed to change frequently. There are no managers, and all decision power and organization is based on the delegates system.
On a larger scale, a group of delegates may in turn elect a delegate in a higher position to pursue their mandate, and so on, until the top delegates are running the industrial system of a state. In such a system, decision power rises from bottom to top from the agendas of the workers themselves, and there is no decision imposition from the top, as would happen in the case of a power seizure by a bureaucratic layer that is immune to instant revocation.
Several times in modern history, the idea of workers' councils has been attributed to similar forms of organization, although in most cases the workers didn't actually have full power control and were subdued to some external authority. Examples include:
Despite Lenin's declarations that "the workers must demand the immediate establishment of genuine control, to be exercised by the workers themselves", on May 30, the Menshevik minister of labor, Skobolev, pledged to not give the control of industry to the workers but instead to the state: "The transfer of enterprises into the hands of the people will not at the present time assist the revolution [...] The regulation and control of industry is not a matter for a particular class. It is a task for the state. Upon the individual class, especially the working class, lies the responsibility for helping the state in its organizational work."
In the workers' councils organised as part of the 1918 German revolution, factory organisations, such as the General Workers' Union of Germany (AAUD), formed the basis for organising region-wide councils. The council communists in the Communist Workers' Party of Germany advocated organising "on the basis of places of work, not trades, and to establish a National Federation of Works Committees."
