This study offers a comprehensive analysis of the process of gaining and implementing public school administrators' right to unionize. The first two chapters consider why school administrators perceive the need for negotiation rights. Chapter I incorporates literature on the changing role, status, and work ethos of educational administration. Chapter II discusses four approaches to affiliation that administrators may take: with community, top managers, teachers, or with one another in a union-like relationship. Chapter III surveys the process of public policy-making and its effects for school supervisors, focusing on the passage and implementation of California's Rodda Act. Chapter IV details the implementation of state labor laws by school districts and by state bodies in California and Florida. Chapter V analyzes the metamorphosis of school administrator associations from clubs to unions in response to state policies and presents comparative data on administrator organizations in six districts. Chapter VI, which explores changes in the ideology and attitudes of school administrators as local bargaining develops, reports a survey revealing that union membership and collective bargaining among school middle administrators are strongly related to the level of agreement with top managerial opinions. Chapter VII speculates on future developments in unionization of school administrators and other public sector supervisors. (MJL)
