This learning unit on supervising with authority is one in the Choice Series, a self-learning development program for supervisors. Purpose stated for the approximately eight-hour-long unit is to enable the supervisor to define authority, distinguish between different types of authority, and use authority more effectively in the workplace. An introduction provides an overview of the unit and lists unit objectives. Parts A through C contain informative material, activities and answer keys, self-checks and answer keys, and a summary. Topics include authority, kinds of authority, and using one's authority. Part D contains performance checks--an end check to be completed alone and a tutor check and work-based project. Part E consists of a brief unit review, extensions (print sources of additional information, such as units or sections in books), and a list of references. (YLB)
