In order to make evident the instrumental nature of the concept of culture applied to organization, this essay develops a comprehension of the concept of organizational culture. This effort is important because the concept of organization itself implies a construction of a social order from meanings becoming hegemonic in the framework of a particular context. Organizational Psychology, even with its neutrality pretension, is not innocent about the instrumental role that social sciences have had in the organizational arena; however this essay introduces alternatives from critical approaches that allow ways of comprehension and why not, intervention from perspectives explicitly political.
