Work-Related Stress Risk Explained: 6 HSE Factors

HSE reports that 964,000 workers in Great Britain suffered work-related stress, depression or anxiety in 2024/25, with 22.1 million working days lost to those conditions. This explainer shows how EHS and HR teams can turn the six HSE factors into a practical work-related stress risk assessment instead of another well-being campaign.

Work-related stress risk is the likelihood that job design, management practices, or workplace relationships will overload a worker's capacity to cope. The HSE Management Standards organize that risk into six assessable factors: demands, control, support, relationships, role, and change.

What are the 6 HSE factors in work-related stress risk?

The 6 HSE factors are demands, control, support, relationships, role, and change. HSE explains that these six areas of work design are associated with poor health, lower productivity, and increased accident and sickness absence rates when they are not managed properly.

Most organizations treat stress as an individual resilience issue, yet the HSE model starts somewhere more uncomfortable: work design. As Andreza Araújo argues in Safety Culture: From Theory to Practice, culture appears in routine decisions, which means psychosocial risk has to be read in schedules, staffing, autonomy, leadership behavior, and change communication.

Demands

Workload, work pace, work patterns, emotional load, and the physical environment surrounding the task.

Control

The degree of influence workers have over how and when work is done.

Support

Practical help, resources, information, and managerial backing available to the worker.

Relationships

The quality of interpersonal treatment, including conflict, bullying, and unacceptable conduct.

Role

Clarity about responsibilities, authority, priorities, and possible conflicts between expectations.

Change

How organizational change is planned, communicated, paced, and absorbed by teams.

Why is demands not the same as workload?

Demands is broader than workload because it includes volume, pace, shift pattern, emotional exposure, environmental strain, and the mismatch between task requirements and available resources. A 12-hour shift with predictable flow may be safer than an 8-hour shift in which priorities change 9 times before lunch.

Across 25+ years leading EHS at multinationals, Andreza Araújo has observed that the hidden demand is often not the number of tasks but the number of unresolved conflicts inside the work. A supervisor who receives production pressure, quality escalation, and safety instructions with no clear priority is not just busy. That supervisor is managing contradiction.

The assessment should therefore record demand by source. Separate volume from urgency, urgency from role conflict, and role conflict from staffing. When everything is labeled workload, the only proposed fix becomes headcount, even though the real control may be planning discipline, clearer escalation rules, or a hard limit on same-day priority changes.

How do you differentiate the 6 factors in practice?

The fastest practical test is to ask what would have to change for the risk to fall within 30 days. If the answer is staffing, sequencing, or equipment, the issue probably sits under demands, especially when impossible deadlines have become routine. If the answer is decision rights, it is control. If the answer is information, coaching, or manager response, it is support.

ISO specifies that ISO 45003:2021 gives guidance for managing psychosocial risk within an ISO 45001 occupational health and safety management system. That matters because psychosocial risk should enter the same risk logic as other hazards: identify the source, assess exposure, define controls, assign owners, and verify effectiveness.

In more than 250 cultural-transformation projects supported by Andreza Araújo's team, the useful conversation starts when leaders stop asking whether people are stressed and start asking which work condition is producing avoidable stress. That shift turns a vague climate concern into an operational risk register.

When should EHS use HSE factors instead of ISO 45003?

EHS should use the HSE factors when the team needs a simple diagnostic language for managers, supervisors, and HR business partners. ISO 45003 is better when the organization needs a management-system structure connected to ISO 45001, audit routines, documented actions, and continual improvement.

The two lenses work best together. The HSE factors name the stressors in language a plant manager can understand, while ISO 45003 defines the management expectation around psychosocial hazards. ILO describes psychosocial hazards as aspects of work design or management that increase work-related stress risk, which reinforces the need to treat them as hazards rather than private weakness.

A practical split is simple: use HSE factors for the interview guide and scoring rubric, then use ISO 45003 for governance. The first gives you the vocabulary for evidence collection. The second gives you the operating system for assigning actions, checking effectiveness, and reporting progress through the OH&S management process.

What traps make stress risk assessments fail?

The most common trap is measuring symptoms while ignoring causes. Absenteeism, turnover, survey comments, and Employee Assistance Program use can show pressure, but they do not prove which part of the work is creating risk unless the assessment connects them to the six HSE factors.

A second trap is outsourcing the topic entirely to HR. Psychosocial risk affects health, safety, reliability, and decision quality, so EHS must stay involved when workload, fatigue, role ambiguity, conflict, and change pressure influence operational control. This is especially true in high-risk work, where cognitive overload can degrade permit quality, handover quality, and field verification.

A third trap is treating the assessment as confidential listening with no visible control plan. Workers become less willing to speak when they report the same problem 3 times and see no change in staffing, shift design, supervisor behavior, or change communication. Safety is about coming home, and that includes coming home without work design steadily eroding health.

Each month without a structured work-related stress risk assessment leaves leaders reacting to sickness absence after the harm is visible, while the controllable sources of demand, role conflict, and unmanaged change continue inside the operation.

How should a 30-day assessment start?

A 30-day assessment should start with one department, six factor scores, and a short evidence pack for each score. The goal is not to diagnose workers. The goal is to diagnose the work conditions that create preventable psychosocial exposure and then decide which controls can change those conditions.

Begin with 8 to 12 interviews across operators, supervisors, HR, and EHS, then compare the themes with sickness absence, overtime, turnover, change calendars, incident reports, and near-miss quality. The strongest early signal is consistency across sources, because the same pattern appearing in interviews and operational data usually points to a real work-design issue.

6 factors are enough for a first scoring map, provided each score names evidence, owner, and control. 30 days is enough for a pilot when the scope is one department rather than the entire company. For practitioners ready to apply this end to end, Safety Culture Diagnosis offers a practical way to connect perception, leadership behavior, and operational evidence.

The practical close, after a focused psychosocial-risk audit, is a one-page register: factor, evidence, exposed group, current control, missing control, owner, deadline, and review date. If the register does not change work design, the assessment has become documentation rather than risk management.

Conclusion

Work-related stress risk assessment becomes useful when the six HSE factors are treated as work-design evidence, not as a wellness vocabulary.
