How to spot the early signs of stress in your team
Spotting stress early is one of the most effective ways managers can prevent long-term absence, protect performance and maintain a healthy team culture. Work-related stress remains one of the most significant risks facing UK organisations, with 964,000 workers experiencing work-related stress, depression or anxiety in 2024/25. This accounted for a major proportion of work-related ill health and led to 22.1 million working days lost across the UK workforce.
For managers and HR teams, this means one thing: identifying signs of stress early is no longer optional — it’s essential. Acting early helps reduce sickness absence, protects productivity and improves retention. The HSE also stresses that preventing work-related stress is a legal health and safety duty, not simply a wellbeing initiative.
Yet stress often develops quietly. Employees may hide how overwhelmed they feel, managers may mistake early warning signs for performance problems, and workloads can escalate before anyone realises the impact. That’s why recognising behavioural, emotional and physical indicators — and knowing what to do next — is critical for any leader responsible for people.
This guide gives managers a clear, practical way to identify these early signals and intervene confidently before issues escalate.

Behavioural, emotional and physical signs of stress
The HSE highlights that when employees begin acting or feeling differently, these changes may indicate rising stress — especially when the behaviour is new or out of character. Managers should look for patterns in behaviour, mood and performance, as stress often shows up long before an employee asks for help.
Here are the key categories of stress related signs:
Behavioural signs
Changes in behaviour are often the earliest and most noticeable indicators. The HSE notes that stressed employees may:
• Take more time off or arrive late
• Become more nervous, jumpy or restless
• Struggle with concentration or decision-making
• Withdraw socially or avoid team interactions
• Show increased conflict, irritability or frustration
At a team level, managers may also see more arguments, reduced performance or a rise in complaints and grievances.
Emotional signs
Stress often affects how employees feel, which can then impact team dynamics and productivity. Common emotional signs include:
• Mood swings and sudden changes in temperament
• Loss of motivation, confidence or commitment
• Feeling overwhelmed or unable to cope
• Increased emotional reactions — tearfulness, sensitivity or aggression
These emotional indicators often appear before an employee takes time off, making early conversations essential.
Physical signs
Stress impacts the body as much as it impacts behaviour or emotions. Employees experiencing stress may show:
• Fatigue or low energy
• Headaches or tension
• Difficulty sleeping
• Changes in appetite
• Muscle tension or restlessness
The HSE advises that while these symptoms may have other causes, managers should still consider workplace pressure as a contributing factor — and act accordingly.
Early recognition doesn’t just protect wellbeing. It prevents avoidable costs, maintains team stability and supports stronger leadership decision-making.

What leadership teams should do next
Once early signs of stress appear, managers must act quickly and confidently. The HSE emphasises that preventing work-related stress is a legal duty, which means managers cannot wait for issues to escalate before responding. Acting early protects performance, reduces the risk of absence and helps employees feel supported before pressure becomes unmanageable.
Here are the next steps every manager should take:
1. Assess what’s driving the pressure
Look at workload, deadlines, team dynamics and recent organisational changes. Many stressors map directly to the HSE’s six Management Standards: demands, control, support, relationships, role, and change — all factors known to increase work-related stress if not managed properly.
Ask yourself:
• Has workload increased?
• Are expectations clear?
• Have responsibilities changed without enough guidance?
• Are team relationships strained?
Understanding the “why” behind the signs will help you take meaningful action.
2. Look for patterns – Not one-off behaviours
The HSE advises watching for changes that persist or become more frequent, such as rising absence, reduced performance or signs of conflict.
Patterns tell you that the issue may be work‑related and requires intervention.
3. Create space for a private, timely conversation
Don’t let the situation drift. Early, supportive discussion helps prevent decline. Managers should reach out as soon as concerns arise, aligning with the Working Minds “Reach Out” step.
Choose a quiet, uninterrupted environment and allow enough time for an open conversation.
4. Document observations
Keep a simple record of what you’ve noticed — behaviours, changes in performance, time off, concerns raised, and actions taken. This supports consistency, protects the organisation and helps track whether things improve.
5. Take practical action
Adjust workloads, clarify expectations, review deadlines or offer more structured support. Small, proactive adjustments often prevent costly issues later on.
How to have the conversation
Approaching an employee about stress can feel sensitive, but the right structure makes the discussion safe, supportive and productive.
The HSE Working Minds 5 Rs
Working Minds is HSE's campaign to help employers prevent work-related stress and support good mental health at work. It's built around five simple steps, known as the 5 Rs:
Reach out: have regular, open conversations with your team and ask how people are, so they feel able to raise concerns early.
Recognise: learn the signs of stress and the common causes, using the HSE Management Standards to identify where pressure is coming from.
Respond: take action to reduce the causes of stress, such as adjusting workloads, clarifying roles or carrying out a stress risk assessment.
Reflect: review what you've done, check whether it's working and plan any further changes.
Make it Routine: build these steps into everyday management, such as regular check-ins, team meetings and annual risk assessment reviews.
The steps in this guide follow the same approach. Spotting the signs covers "Recognise", the conversation covers "Reach out" and "Respond", and follow-up reviews cover "Reflect" and "make it Routine". Source: HSE Working Minds
Below is a simple approach that managers can use:
Start with observations, not assumptions
Use factual, neutral language:
• “I’ve noticed you’ve seemed quieter lately.”
• “I’ve seen a change in your workload or energy levels.”
This helps the employee feel seen, not judged.
Ask open, supportive questions
Invite them to share their perspective:
• “How are things feeling for you at the moment?”
• “Is anything at work making things more difficult right now?”
This aligns with the HSE’s recommendation to normalise conversations about pressure.
Listen without interruption
Demonstrate psychological safety through calm listening, patience and empathy. Avoid rushing to solutions before understanding the root causes.
Explore what support will help
Discuss changes that could relieve pressure — workload, priorities, communication styles, clarity, or team support. This supports “Respond,” one of the Working Minds 5 Rs.
Agree the next steps together
Summarise what you’ve discussed, agree on adjustments, outline what you’ll do next and schedule a follow‑up conversation to “Reflect” — ensuring progress is reviewed over time.

When to escalate
Some situations require specialist help beyond the manager’s remit. Escalating early protects the employee, prevents further decline and ensures compliance with legal responsibilities.
Escalate when:
Stress indicators persist or worsen
If the employee continues to show signs of stress despite changes, or if their wellbeing noticeably deteriorates, escalation is necessary.
There are signs of burnout or withdrawal
Signs such as emotional exhaustion, disengagement, prolonged absence or sharp performance decline indicate deeper issues. Escalate to HR or clinical support immediately.
The issue involves conflict, bullying or relationship breakdown
The HSE advises that managers must take action when relationship issues are driving stress, and such cases often require HR involvement.
There are concerns about mental health or safety
If you believe someone is at immediate risk of harming themselves, call 999. Samaritans is available 24/7 on 116 123." A page about spotting distress should say what to do in an emergency.
Legal or compliance risks are present
Employers have a legal duty to assess and manage the risk of work-related stress. Under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999, that includes identifying the causes of stress, such as workload, role clarity, poor communication or organisational change, and taking action to reduce them. If stress is linked to a mental health condition that meets the definition of a disability, the Equality Act 2010 also requires employers to consider reasonable adjustments.
Failing to act can lead to grievances, long-term absence and legal claims. If you're unsure what your obligations are in a particular case, involve HR at an early stage. For more detail, see our guides to reducing work-related stress and reasonable adjustments at work.

How an EAP can help leadership teams respond early and effectively
Even the most capable managers can struggle to respond consistently when team stress levels rise. Heavy workloads, limited time and lack of clinical expertise make it difficult to confidently identify risks, manage sensitive conversations or provide the right support at the right time. This is where a clinically governed, accredited Employee Assistance Programme (EAP) becomes invaluable.
Wisdom Wellbeing’s EAP provides that support. Trusted by 88,000+ worldwide, it offers managers a simple, reliable way to act early, reduce risk and protect their team’s wellbeing.
With fast access to specialist interventions and expert guidance, the EAP strengthens each step managers need to take after spotting early signs of stress. When an employee shows behavioural, emotional or physical indicators of stress, quick access to professional help prevents escalation.
Conclusion
Spotting stress early is one of the most powerful ways managers can protect their people and their organisation. Early intervention is now essential for safeguarding performance, workforce retention and legal compliance.
By learning the behavioural, emotional and physical signs — and responding quickly through supportive conversations and practical adjustments — managers can prevent issues from escalating into long-term absence or burnout.
And with the support of a clinically governed EAP like Wisdom Wellbeing, managers have the tools, expertise and confidence to act early, escalate appropriately and protect the wellbeing and resilience of their teams.
