This document discusses managing drug and alcohol misuse in the workplace. It finds that about half of employers have disciplined employees for alcohol misuse and a quarter for drug misuse. The top reasons for workplace policies on misuse are promoting safety, supporting employee health, and addressing poor performance. Most employers communicate policies through staff handbooks and intranets, but few train managers. While most employers do not test for drugs or alcohol, safety-critical workplaces often do, typically for suspected issues. Employers commonly take a combined disciplinary and health approach to misuse issues and provide counseling, disciplinary procedures, and occupational health support.
