In this third episode, Associate Professor Goodman Sibeko and Associate Professor Nadine Harker discuss how workplaces can identify early signs of substance use and mental health challenges among employees, and respond appropriately before issues escalate.
Prof. Harker explains the occupational factors that increase risk, the visible and behavioural cues supervisors should look out for, and the importance of distinguishing between informal and formal referrals. She outlines how supervisors can express concern, make soft referrals to employee wellness or HR, and when formal action becomes necessary.
The discussion also covers how consistent health promotion, supportive policies, and structured employee assistance programmes can help organisations address problems early, reduce stigma, and maintain both compassion and productivity.
