"Classical theory describes (and prescribes) organizations as systems that have the capacity of making rational decisions. They pursue objectives and are in control of their instruments. […] Control of instruments means control of motives to contribute to the organization. But how is it possible to control motives if humans are conceived as subjects, that is, as self-organizing entities? The answer is: by membership. Subjects decide to enter the system, to use their freedom to accept constraints, that is, to establish a "zone of indifference" within which the organization or the "executive" on its behalf can select what he wants to be done."
