Psychosocial hazards are hazards that arise from or about the design or management of work, the working environment, and workplace interactions or behaviours and may cause psychological and physical harm. ​ These hazards can lead to conditions such as anxiety, depression, post-traumatic stress disorder (PTSD), sleep disorders, musculoskeletal injuries, chronic diseases, and physical injuries following fatigue-related workplace incidents. ​ The body's reaction to these hazards is stress, which can have physiological and psychological effects. ​ While stress is not an injury, frequent, prolonged, or severe stress can cause harm. ​It is essential to manage psychosocial hazards to protect workers' health and safety, reduce costs and disruptions associated with injuries, and improve overall organisational performance and productivity. ​
