This manual is designed to help supervisors perform their duties, whether in the public or private sector or in a community organization. It provides information to help supervisors understand the individuals with whom they work, orient new workers to their jobs, plan and organize the work to be performed, assign and monitor tasks, conduct training sessions to provide work competencies, provide counseling to solve work-related problems, and certify time and attendance records. The information is organized into five sections, plus a bibliography. Sample forms are provided for a work site agreement, a statement of work, and a performance evaluation. The guidelines included in this manual were derived from a synthesis of the Comprehensive Employment and Training Act (CETA), statutes of the Manpower Development and Training Act and the Economic Opportunity Act, as well as from literature written in recent years to provide structure for supervisors who work in summer youth work-experience programs. The target populations for the work sites described in the acts and the literature were primarily disadvantaged youth. (KC)
