If you still think of workplace stress as a "soft" issue, something for HR to handle with a few posters and an Employee Assistance Programme, it's time to think again.
The Health and Safety Executive has made its position clear: managing work-related stress carries the same legal weight as managing physical hazards like slips, trips, and falls. And they're backing that position up with action.
In December 2025, the HSE issued a Notice of Contravention to the University of Birmingham after finding that it had not adequately managed work-related stress across the organisation. HSE said the university’s stress risk assessment was too generic, that it had failed to fully implement its own stress management policy, and that staff had not been properly involved in developing or reviewing the approach. (HSE Confirms Material Breaches at U. of Birmingham Following Union Safety Concerns, 2025)
This wasn't a one-off. In 2025, the HSE confirmed that it was actively investigating suspected organisational failures in managing mental health risks, specifically targeting cases where multiple employees report experiencing work-related ill health.
For anyone running a business or managing a team, the message is hard to miss: this is happening, it's accelerating, and it applies to you.
The Numbers That Should Be on Every Board Agenda
The scale of the problem is staggering. The latest HSE statistics for 2024/25 showed that 964,000 workers were suffering from work-related stress, depression or anxiety – a significant jump from 776,000 the previous year. That's 22.1 million working days lost, almost a third higher than the previous year's figure of 16.4 million.
Stress, depression and anxiety now account for 52% of all work-related ill health in the UK. (HSE publishes annual workplace health and safety statistics, 2025) To put that in context, more than half of all workplace illness is psychological, and the trend is heading in the wrong direction.
These aren't abstract numbers. For SMEs and charities, they translate into real operational pain: people off sick, teams stretched thin, recruitment costs climbing, and the quiet drain of presenteeism, where someone's at their desk but nowhere near their best.
What the Law Actually Requires
But here's something many employers don't fully appreciate: under the Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations 1999, employers must assess and manage the risks of work-related stress in the same way as other health and safety risks.
That means conducting proper risk assessments, putting preventive measures in place, and demonstrating that those measures are actually working. Having a stress policy gathering dust on a shared drive doesn't cut it.
According to the Health and Safety Executive (HSE), employers are legally required to protect workers from stress at work by carrying out a risk assessment and taking action based on the findings, which means that proactive measures should be in place to prevent harm rather than focusing solely on responses after stress has become a problem.
This distinction between reactive and proactive matters enormously. The HSE wants to see evidence that organisations are identifying stressors before people become unwell, not just mopping up afterwards.
The HSE Management Standards: Your Compliance Framework
The HSE's Management Standards provide a practical framework for assessing and managing work-related stress. They focus on six key areas:
- Demands: workload, work patterns
- Control: how much say people have
- Support: from the organisation, line managers, and colleagues
- Relationships: including conflict and unacceptable behaviour
- Role: clarity and avoiding conflicting responsibilities
- Change: how organisational change is managed and communicated
If you're a board member reading this, these six areas should be woven into your governance and risk reporting. If you're a line manager, they should inform how you structure workloads, run one-to-ones, and support your team through change and pressure.
The good news? These aren't mysterious or complex concepts. Most of them come down to good management practice: having honest conversations about workload, making sure people understand their role, giving them some autonomy over how they work, and handling change with transparency rather than as an afterthought.
The challenge is doing this consistently and being able to evidence it.
What Boards Need to Do
Senior leaders need to treat psychological risk with the same rigour they'd apply to any other health and safety obligation. That means:
- Ensuring stress risk assessments are carried out at a meaningful level, not just a single, generic document for the whole organisation, but assessments that reflect what's actually happening in different teams and roles.
- Making sure policies aren't just written but implemented, monitored, and reviewed. As the Birmingham case demonstrated, having documents and policies in place is not enough; they must be effective.
- Building stress management into governance reporting so it's visible at board level, not buried in an HR update that gets skipped when time runs short.
What Line Managers Need to Do
For line managers, the HSE Management Standards translate into everyday behaviours: checking in regularly about workload, noticing when someone's struggling, creating space for honest conversations about pressure, and knowing when to escalate concerns.
The HSE's Working Minds campaign breaks this down into five practical steps – Reach out, Recognise, Respond, Reflect, and make it Routine, which offer a useful starting point for managers who want to get this right but aren't sure where to begin.
The key shift here is from seeing stress management as something you do after someone goes off sick to something you build into your regular management rhythm. As the HSE's own stress policy lead put it: 'Prevention is better than cure.'
The Enforcement Landscape Is Changing
In 2024/25, the HSE completed 246 criminal prosecutions, achieving a 96% conviction rate and securing fines exceeding £33 million. (Executive summary: Health and Safety Executive Annual Report and Accounts 2024 to 2025, 2025) And while these prosecutions primarily related to physical safety, the HSE is now prioritising work-related ill health and increasing inspections to assess psychological health alongside physical risks.
Legal commentators anticipate that tougher enforcement and regulatory prosecutions for organisational failures to manage employee mental health are likely in the coming months and years. (Murray & Highfield, 2026)
For smaller organisations, the temptation might be to assume this is a problem for large institutions. But the HSE has been explicit: the expectation applies to all employers. And once enforcement precedents are set, the net will widen.
Getting Ahead of the Curve
None of this needs to be overwhelming. The organisations that manage stress well tend to share a few things in common: they take it seriously at a senior level, they train their managers to have supportive conversations, and they build regular check-ins around the six Management Standards areas into their normal way of working.
The shift from treating wellbeing as a perk to recognising it as a compliance requirement is already underway. The question for every organisation is whether they'll get ahead of it or wait until they're on the wrong end of an investigation.
