This student guide is intended to assist persons employed as supervisors in understanding the legal aspects of supervision. Discussed in the first four sections are the following topics: the nature of the law (criminal and civil law, why people obey the law, and the law and supervisors); health and safety at work (safety in the workplace, ways of encouraging safety, consequences of violating the law, and what the law can expect); employment contracts (spoken and written contracts, rights and obligations, changes in employment contracts, and breach of contract); and dismissal (circumstances for dismissal, dismissal procedures, and constructive dismissals). Each of these sections contains an introduction, sections of instructional text that are interspersed with reinforcing learning activities, and a section summary. The fifth 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)
