If you employ people, you’ll see pressure build from time to time — rising absence, short tempers, mistakes creeping in, or people quietly switching off. It’s easy to treat that as “just HR”. But mental health risks (including work-related stress) sit in the same space as slips, trips, manual handling and fire safety: you’re expected to assess the risk and take sensible steps to control it.

This guide shows you how to bring mental health into your existing risk assessment process in a practical, proportionate way without turning it into a tick-box exercise.

The legal duty (in plain English)

Your duty of care covers health, not just physical safety. The law expects you to protect people from harm at work so far as is reasonably practicable. That includes harm linked to stress and poor mental wellbeing where it’s caused or made worse by work.

You’re also expected to carry out a suitable and sufficient assessment of workplace risks and to review it when it’s no longer valid or when things change significantly. In other words: if work is creating predictable stressors, you should treat them as hazards, assess the risk, and put controls in place and you should be able to show what you’ve done.

What are “psychosocial hazards”?

“Psychosocial hazards” is just a formal way of saying workplace factors that can harm mental health. In everyday terms, they’re the parts of the job or environment that can drive ongoing stress, anxiety, low mood, conflict, burnout, or poor coping.

A simple way to think about it is: what in the way we organise work could push people from ‘busy’ into ‘unwell’?

What counts as a mental health risk at work?

You’ll usually see the same themes come up. Common work-related stressors include excessive workload (unrealistic deadlines, constant firefighting, not enough people or time) and a lack of control, where priorities change without warning and people have little say in how work is done. Poor support also plays a big part — for example, unclear feedback, inconsistent decisions, and too little time for supervision.

Alongside that, there are a few risk areas you should look out for in most workplaces:

• Bullying, conflict, or strained relationships (tension, harassment, repeated friction)
• Role issues (unclear responsibilities, conflicting demands, blurred boundaries)
• Job insecurity or uncertainty (rumours, restructuring, unclear messaging)
• Poorly managed change (sudden shifts in expectations, no consultation, weak communication)

These aren’t “soft” issues. If they’re present and persistent, they can lead to real harm — and they can also increase mistakes and incidents.

How to build mental health into your existing risk assessments

You don’t need a separate, complex process if your current risk assessment approach is sound. Most businesses do best by using the same familiar steps they already apply elsewhere: identify the hazards, decide who may be harmed, judge the level of risk, put controls in place, record what you’ve done, and review it regularly.

Step 1: Identify the stressors (use evidence, not gut feel)

Start with what you already know: patterns in sickness absence, themes coming up in return-to-work conversations, turnover, recurring complaints or conflict points, overtime levels, and indicators like error rates or missed deadlines.

Then add what you need to ask. The questions below can be used in 1:1s, team check-ins, or a short survey:

• “What makes your job harder than it needs to be?”
• “Where do priorities change without warning?”
• “What support would make the biggest difference?”
• “What gets in the way of taking breaks or finishing on time?”

Step 2: Consult people properly (and make it safe to be honest)

This is where many organisations slip — not through bad intent, but because it feels awkward to ask. You don’t need a huge programme. You do need a method that gives people confidence they can speak openly, and that the purpose is improvement rather than blame.

A workable SME-friendly mix is to run one short anonymous pulse survey, then follow it with a structured team discussion to explore themes and agree priorities. If that’s not suitable, use a few short interviews across different roles, or involve a staff rep or small working group to sense-check findings.

Step 3: Assess likelihood and impact

Keep it consistent with your normal risk scoring. Likelihood is about how often the stressor shows up and how widespread it is; impact is about the harm it could cause, from short-term stress through to longer-term absence and knock-on risks like errors and incidents.

Be honest. If you’ve got repeated absence, ongoing conflict, constant overtime or regular complaints about workload, the risk level is rarely “low”.

Step 4: Put controls in place (focus on causes, not just coping)

The most effective actions deal with how work is designed and managed — not just how individuals cope with it.

Good controls often include:

• clearer workload planning and prioritisation (including what stops when something new arrives)
• agreed response times and boundaries (reducing “always on” pressure)
• training for line managers on spotting early signs and having supportive conversations
• consistent processes for resolving conflict
• better change planning and communication (what’s changing, when, and what support is in place)

If you already offer support like an EAP or wellbeing resources, keep them — but treat them as supportive measures, not the main control.

Step 5: Record it and review it

You’re aiming for a documented approach that shows what the main stressors are, who is affected, what controls you already have, and what actions you’re taking (with owners and deadlines). Review progress regularly, refresh the assessment at least annually, and revisit sooner if there’s significant change.

Practical controls you can put in place quickly

If you want a simple starting point, focus on the basics that make the biggest difference. Workload planning needs to be visible and realistic, including what gets paused when priorities shift. Regular check-ins should include a quick “how are you coping?” — not just task updates. And managers should have enough training and structure to respond consistently, especially during periods of change.

A few practical measures that tend to work well are:

• Clear reporting routes for concerns, conflict, and workload pressures
• Fair, predictable communication during change so people aren’t left guessing

Small improvements here often reduce stress more than any single “wellbeing initiative”.

Common gaps (and why they cause problems)

These are the patterns that usually lead to trouble. Many organisations treat mental health as HR-only, so it never reaches risk management. Others do supportive things informally but keep no record, which makes it hard to show a consistent approach. A common trap is to wait until someone goes off sick before acting, or to rely heavily on individual resilience rather than fixing root causes.

A few other gaps are worth watching for:

• Managers left to “figure it out” without training or structure
• Inconsistent responses across teams, which can make problems worse

If any of these sound familiar, the fix is rarely complicated — it’s usually about putting a consistent, documented process around what you already care about.

A simple approach you can adopt now

If you want something workable without overengineering it, start by adding work-related stress to your risk assessment register (or creating a dedicated stress risk assessment in your usual format). Use six practical headings to identify stressors: workload, control, support, relationships, role clarity, and change.

From there you can run one short pulse survey plus a structured team discussion and choose 3–5 priority actions that tackle root causes, with owners and deadlines. You should review progress quarterly and refresh the assessment annually (or sooner after major change)

How The Health & Safety Dept can help

If you’re not sure how to turn “we know people are struggling” into a structured, defensible process, that’s exactly where support pays off.

The Health & Safety Dept can help you:

• carry out stress and psychosocial risk assessments in a practical, evidence-led way
• run short workplace surveys and structured consultation
• train managers to spot early risk indicators and respond consistently
• act as your Competent Person adviser, helping you document actions and keep everything review-ready

If you’d like a clear starting point, a short stress risk “health check” will highlight what’s driving pressure, where the gaps are, and what to prioritise first — with actions that fit your workplace, not a generic template.
