This student guide is intended to assist persons employed as supervisors in learning the principles of industrial relations. Discussed in the first eight sections are the following topics: the nature and scope of industrial relations, management organizations and employers' associations, unions, the rights and roles of union representatives, the organization of unions, individual and collective matters, and Great Britain's Advisory Conciliation and Arbitration Service. Each of these sections contains an introduction, sections of instructional text that are interspersed with reinforcing learning activities, and a section summary. The ninth part of the guide includes a series of performance checks (an end check, a tutor check, and a work-based project). Concluding the guide is a unit review that reviews the objectives addressed in the guide, describes related extension courses, and lists recommended reference materials. (MN)
