Work-related problems associated with employees who abuse alcohol and/or other drugs are briefly reviewed in this pamphlet to encourage employers to consider setting up a substance abuse program in their companies and businesses. The pamphlet then goes on to explain briefly each of five steps involved in developing a workplace substance abuse program: (1) writing a clear and comprehensive substance abuse policy; (2) training supervisors to detect performance problems that may indicate substance abuse; (3) educating employees about the program; (4) providing employee assistance through an employee assistance program; and (5) starting a drug testing program. Ideas are offered for taking each step. A resource list of organizations that can be contacted for help in establishing such a program is included, as is information on regulations that must be considered by employers dealing with some federal contracts or performing certain types of work.
