In this session Professor Tim Marsh explores the vital connection between mental health and workplace safety, highlighting how wellbeing and employee engagement directly influence safety performance. He delves into behavioural safety by examining why people act the way they do at work - looking at habits, shortcuts, and decision-making processes. Tim emphasizes that many accidents happen during routine, moderately hazardous tasks when workers are tired, distracted, rushing, or emotionally unsettled, often due to mental health challenges. The session offers practical insights on how supporting mental wellbeing can reduce risk, improve safety culture, and foster better decision-making on the job.
