Kibbutz communities are to be classified within the framework of modern society as having a highly developed technology and a secular Weltanschauung. Female hierarchies have been described and analyzed mainly in primate groups. The hierarchical order among the females may be specific to a certain task or diffuse in the sense that it may be based on general status among the families and/or in the society as a whole. In the kitchen, the dominant female is the branch manager. She is the decision maker in both matters of distribution of goods and work assignment organization. In the communal storerooms, some of the workers are exempted from the hierarchical relations, and in childcare, hierarchical relations are limited to emergency situations. The structure of work organization greatly affects both the intensity and the scope of hierarchical relations. Female hierarchy is plausible in an extended family where more females interact in the same unit.
