Managing Psychosocial Hazards in Manufacturing

The WHS Regulation 2025 explicitly regulates psychosocial hazards for the first time, requiring PCBUs to identify psychosocial hazards, assess the risks, and implement controls to eliminate or minimise those risks so far as is reasonably practicable. This is not new law — the duty to manage risks to psychological health has always existed under the general duty provisions of the WHS Act. What has changed is that psychosocial hazards are now named in the regulation with specific obligations for identification, assessment, and control. For manufacturing businesses, this means psychosocial risk assessments must sit alongside physical and chemical risk assessments in your WHS management system. Regulators have indicated that they will audit psychosocial risk management as part of routine workplace inspections, and enforcement action will follow where PCBUs have not addressed these hazards. Manufacturing environments present specific psychosocial risk factors including production pressure, shift work, repetitive work, poor organisational change management, and exposure to traumatic events such as serious workplace injuries.

Manufacturing environments present several psychosocial hazards that require systematic identification and control. High job demands and production pressure drive workers to take shortcuts, skip breaks, and accept excessive workloads, leading to fatigue, stress, and increased physical injury risk. Shift work disrupts circadian rhythms, sleep patterns, and family life, contributing to fatigue-related errors, cardiovascular disease, and mental health conditions. Low job control, where workers have minimal influence over how they perform their tasks due to rigid production processes, is associated with increased stress and psychological distress. Repetitive and monotonous work creates disengagement, boredom, and reduced vigilance that increases both psychological distress and physical injury risk. Poor organisational change management, including restructuring, redundancy, and technology changes, creates uncertainty and anxiety across the workforce. Workplace bullying and harassment, including from supervisors using pressure to meet production targets, undermines psychological safety. Exposure to traumatic events such as witnessing a serious workplace injury affects colleagues and first responders with potential for post-traumatic stress.

A psychosocial risk assessment in manufacturing should follow the same systematic approach used for physical hazards: identify, assess, control, and review. Identification methods include worker surveys using validated tools such as the People at Work psychosocial risk assessment instrument, focus groups with workers from different departments and shifts, review of data including workers compensation claims for psychological injury, absenteeism patterns, turnover rates, and grievance records, and consultation with workers and health and safety representatives. The assessment should evaluate each identified hazard against the likelihood and severity of harm, considering the number of workers exposed, the frequency and duration of exposure, and the interaction between psychosocial hazards and physical hazards such as fatigue increasing the risk of machine injuries. The assessment must be documented and include the identified hazards, the assessed risk level, and the controls to be implemented. Workers must be consulted during the assessment process. The assessment should be reviewed at least annually and whenever significant organisational changes occur.

Effective psychosocial hazard controls in manufacturing address the source of the hazard rather than relying solely on individual resilience programs. For high job demands and production pressure, controls include realistic production targets based on achievable work rates, adequate staffing to cover peak demand and absence, and formal procedures for managing production delays without pressuring workers to bypass safety controls. For shift work, controls include forward-rotating shift schedules that minimise circadian disruption, adequate rest periods between shifts as specified in the regulation, access to healthy food options during night shifts, and fatigue risk management systems. For low job control, controls include worker involvement in process improvement and problem-solving, skill development and cross-training to increase variety, and team-based work organisation that gives groups autonomy over task allocation. For workplace bullying and harassment, controls include clear behavioural expectations for supervisors and workers, confidential reporting channels, and consistent investigation and consequence management. For traumatic event exposure, controls include a critical incident response plan with trained peer supporters and access to professional psychological support.

Psychosocial risk management should not be a standalone program disconnected from the rest of your WHS management system. It should be integrated into existing hazard identification, risk assessment, and incident reporting processes. Add psychosocial hazards to the hazard categories in your risk assessment templates so they are considered alongside physical, chemical, and biological hazards during workplace inspections and task assessments. Include psychosocial factors in incident and near-miss investigation by asking whether fatigue, production pressure, or poor communication contributed to the event. Incorporate psychosocial risk indicators into management reporting alongside physical injury rates, so that senior management has visibility of both physical and psychological safety performance. Train supervisors in psychosocial hazard awareness and their role in creating psychologically safe work environments. This includes recognising early signs of distress in workers, managing workload constructively, and responding appropriately to reports of bullying or harassment. Review psychosocial controls during internal audits using the same systematic approach applied to physical hazard controls. EHS Atlas integrates psychosocial risk assessment, incident reporting, and control tracking into the same platform used for all other WHS management activities.
