This document was written for anyone concerned about substance abuse in the workplace. It offers helpful advice to top management, supervisors, employee representatives, and workers. The first section discusses whether drugs in the workplace are a problem, the next section explains how to tell if employees have problems with drugs, and the third section discusses what can be done about the problem of drugs in the workplace. It is recommended that top management review organizational options, set the policy, and assign accountability. Supervisors are encouraged to confront workers with performance problems and to refer workers to employee assistance programs (EAPs) or other forms of assistance. It is suggested that employee representatives consult with management, that union representatives develop a member assistance program, and that workers themselves establish a system of peer referral. A section on alternatives to drugs in the workplace explores EAP options. Descriptions of 10 model programs and three sample policies are appended, along with drug fact sheets on cannabis, inhalants, cocaine, other stimulants, depressants, hallucinogens, narcotics, and designer drugs. A discussion of drug testing and list of resources are also included. (NB)
