These teacher's materials for a three-unit competency-based course were developed to provide employers and their employees with current information about ways to protect themselves against personal and business-related crimes. They may be used in secondary and postsecondary education settings and in short-term adult training programs. The three units are on establishing a secure work environment, applying on-the-job security procedures, and taking precautions for personal safety. The first section is designed to show teachers how to use the materials and includes an explanation of instructional elements, an instructional task analysis for each unit, a glossary, and a list of 12 references. The instructional elements for the units include objectives, suggested activities, information sheets, transparency masters, assignment sheets, answers to assignment sheets, job sheets, tests, and test answers. Some elements, such as the information sheets, include diagrams and line drawings. (CML)
