Work-related stress is defined by HSE as the adverse reaction people have to excessive pressures or other types of demand placed on them; it is not an illness in itself.

Stress becomes a recognised health concern when it is prolonged or intense enough to produce psychological and physiological strain, which can then precipitate anxiety, depression and burnout.

The demand-control-support model (Karasek and Theorell) predicts highest strain where psychological demands are high, decision latitude is low and social support is weak.

The effort-reward imbalance model (Siegrist) predicts ill health where high effort is paired with low reward in money, esteem, security or career opportunity.

The biopsychosocial model holds that mental ill health arises from interacting biological, psychological and social factors, so workplace stressors act alongside individual vulnerability rather than in isolation.

The Yerba-Maslow-style inverted-U (Yerkes-Dodson) curve links arousal to performance: moderate pressure aids performance, while very low or very high arousal degrades it.

Presenteeism, defined as attending work while unwell, is a recognised mediator between stress and reduced productivity, distinct from absenteeism.

HSE's Management Standards cover six primary stressors: demands, control, support, relationships, role and change; each maps to a defined set of working conditions.

The six HSE stressor categories are demands (workload, work patterns, environment), control (how much say a person has), support (encouragement, sponsorship, resources), relationships (promoting positive working to avoid conflict), role (understanding of role) and change (how organisational change is managed and communicated).

Common demand stressors include excessive workload, long hours, unrealistic deadlines, shift work, lone working and physical hazards such as noise, heat or poor ergonomics.

Common control stressors include low decision latitude, micromanagement, lack of autonomy over pace or method, and unclear limits of authority.

Common support stressors include inadequate induction, training or supervision, absence of managerial feedback, and lack of access to occupational health or employee assistance resources.

Common relationship stressors include bullying, harassment, discrimination, unresolved conflict, and a culture that tolerates incivility.

Common role stressors include role ambiguity (unclear expectations) and role conflict (incompatible demands from different parties).

Common change stressors include poorly communicated restructuring, job insecurity, altered shift patterns and unclear consultation processes.

Individual effects of stress include fatigue, sleep disturbance, anxiety, irritability, lowered concentration, increased errors and musculoskeletal complaints; organisational effects include higher absence, turnover, accidents, poor quality and reduced productivity.

Under the Health and Safety at Work etc. Act 1974, employers must ensure, so far as is reasonably practicable, the health, safety and welfare of employees, which includes psychological health.

The Management of Health and Safety at Work Regulations 1999 require suitable and sufficient risk assessment; stress is a hazard to be assessed like any other.

The Equality Act 2010 requires reasonable adjustments where an employee has a disability, which can include a stress-related mental health condition that meets the statutory definition of disability.

HSE's Management Standards set out the employer's role: identify stress risks, assess them, put controls in place, and monitor and review their effectiveness.

Managers are responsible for implementing controls at team level: setting clear expectations, holding regular one-to-ones, managing workload and addressing conflict promptly.

Individual employees are responsible for raising concerns early, using available support such as employee assistance programmes, and complying with agreed control measures.

Safety representatives have a legal right to be consulted on health and safety matters, including stress risk assessments, under the Safety Representatives and Safety Committees Regulations 1977.

Confidentiality is a legal and ethical duty when handling individual stress cases; personal health information should be shared only on a need-to-know basis, consistent with data protection law.

The HSE Management Standards approach has five steps: identify the hazards, decide who might be harmed and how, evaluate the risks and decide on controls, record findings and implement them, and monitor and review.

The six Management Standards are demands, control, support, relationships, role and change; each has a defined 'states to be achieved' description.

The HSE Indicator Tool is a 35-item questionnaire measuring employee perceptions against the six standards; results are compared with benchmark data.

HSE's analysis guidance sets thresholds: results in the bottom 20% of benchmark scores indicate urgent action; results between the 20th and 50th percentiles indicate improvement needed.

Focus groups are used after survey results to explore why scores are low and to generate practical, locally owned solutions.

The risk assessment should be proportional and involve employees; it should consider the six standards systematically rather than only individual cases.

Recording findings should include the stressor identified, who is affected, the control measure, the responsible person and a review date.

Monitoring and review should use repeat surveys, absence data, turnover data, incident reports and focus group feedback to test whether controls are working.

Interventions are classified as primary (remove or reduce the stressor at source), secondary (help individuals cope, e.g. training, resilience) and tertiary (rehabilitate and support those already affected, e.g. counselling, phased return).

HSE guidance favours primary interventions because they address the cause rather than the symptom; secondary and tertiary measures should complement, not replace, them.

Work redesign interventions include workload balancing, job rotation, increased autonomy, clearer role definitions and improved communication of change.

Organisational interventions include revising policies on bullying and harassment, improving selection and induction, and strengthening supervision and feedback.

Individual-level interventions include stress awareness training, time management, mindfulness and cognitive behavioural approaches, but their effect is limited if the source stressor remains.

Tertiary support includes employee assistance programmes, occupational health referral, reasonable adjustments and phased return-to-work plans.

Intervention effectiveness should be evaluated with pre- and post-measures such as Indicator Tool scores, absence rates, turnover and focus group feedback, and adjusted if not achieving intended outcomes.

A stress policy should state the organisation's commitment, define responsibilities, describe the risk assessment process and set out how individuals can raise concerns confidentially.
