The Anderson-Warkov Hypotheses in Local Unions: A Comparative Study

The size of administrative apparatus in local union organizations with headquarters in Cook County, Illinois, varies directly with the number of members performing identical tasks at the same place, but indirectly with the number of spatially separated places at which members work. Local unions with occupationally diverse memberships have a larger administrative apparatus than those with occupationally uniform memberships. The dependent variable is a measure of the active administrative component, rather than of the formally designated one. It is suggested that differences between the Anderson and Warkov predictions and those reported here may be reconciled if two further variables, the structure of organizational control and systems of communication, are considered.
