Workplace burnout isn’t just a buzzword anymore – it’s a full-blown crisis affecting UK businesses and workers alike. Mental Health UK’s Burnout Report 2025 reveals a stark reality: 91% of UK adults experienced high or extreme stress in 2025, with 1 in 5 (21%) needing time off work due to stress-related mental health issues.
But here’s what’s particularly concerning: whilst overall stress levels remain catastrophically high, there’s a clear generational divide emerging. Younger workers are burning out at increasing rates, whilst older workers show declining stress-related absences.
If you’re a business leader noticing higher turnover amongst younger employees, struggling to retain talent under 40, or seeing productivity dips in your younger teams, work burnout is likely playing a bigger role than you realise.
The UK burnout crisis: the numbers
Mental Health UK’s 2025 Burnout Report paints a concerning picture of the UK workforce’s mental health:
Overall statistics:
- 91% of UK adults experienced high or extreme stress at some point in 2025
- 21% (1 in 5) needed to take time off work specifically due to stress-related mental health issues
- Stress-related absences continue to rise despite increased awareness and workplace wellness programmes
- Younger age groups (18-24, 25-34, 35-44) show increases in stress-related work absences
- Older age groups (45-54, 55-64, 65+) show decreases in stress-related absences
What this means for UK businesses:
This isn’t just a health issue – it’s an economic crisis. With approximately 32 million people in the UK workforce, these statistics suggest that over 6.7 million UK workers needed time off in 2025 specifically for stress-related mental health reasons.
The financial impact includes:
- Lost productivity during absences
- Reduced performance when burnt-out employees are present but struggling
- Recruitment and training costs when burnout leads to resignations
- Increased healthcare and insurance costs
- Team disruption and morale impacts
The generational divide in workplace burnout
The most striking finding from the 2025 data isn’t just that stress levels remain high – it’s that different generations are experiencing completely opposite trends.
Younger workers: stress increasing
Age groups showing INCREASES in stress-related absences:
- 18-24 years old: Experiencing rising burnout and stress-related time off
- 25-34 years old: Showing increased stress-related absences
- 35-44 years old: Continuing upward trend in burnout
These aren’t minor increases. The generational pattern is clear and consistent across all three younger age brackets.
Older workers: stress decreasing
Age groups showing DECREASES in stress-related absences:
- 45-54 years old: Declining stress-related time off
- 55-64 years old: Reduced burnout indicators
- 65+ years old: Lowest and decreasing stress levels
This creates a paradox: as overall workplace mental health awareness improves and more support becomes available, the youngest workers are struggling more, not less.
What this generational split reveals
This isn’t about younger generations being “less resilient” or “unable to cope” – that’s a dangerous and inaccurate narrative. The data reveals something far more significant: younger workers face fundamentally different workplace challenges that current support systems aren’t addressing.
Why younger workers are burning out faster
Multiple factors converge to create a perfect storm of workplace burnout for younger UK workers:
1. Financial pressure and economic uncertainty
The cost-of-living crisis hits younger workers hardest:
- Housing costs consume a far higher percentage of younger workers’ income
- Student loan repayments add financial burden that older generations didn’t face
- Lower earnings in early career stages whilst living costs have skyrocketed
- Less ability to build savings or financial cushion creates constant anxiety
- Economic uncertainty about job security and career progression
The mental health impact:
Financial stress directly contributes to burnout. When you’re constantly worried about making rent or paying bills, work stress compounds exponentially. Older workers, more likely to own homes or have established savings, have a financial buffer that reduces baseline stress.
2. Always-on work culture and digital burnout
Younger workers entered a workplace with blurred boundaries:
- Expected to be responsive on Slack, Teams, email outside work hours
- Remote and hybrid work means work never physically “ends”
- Social media and digital presence adds performance pressure
- FOMO (fear of missing out) on career opportunities drives overwork
- Difficulty separating personal identity from work achievement
The contrast with older workers:
Workers over 45 often established career boundaries before smartphones existed. They learned to “leave work at work” in a pre-digital era. Younger workers have no frame of reference for genuine disconnection.
3. Uncertain career progression and job insecurity
Traditional career ladders have collapsed:
- Less clear progression pathways than previous generations had
- Need to job-hop to get salary increases older workers got through tenure
- Gig economy and contract work create constant uncertainty
- AI and automation anxiety about job security
- Pressure to constantly upskill just to remain employable
The burnout cycle:
When career progression feels uncertain, many younger workers compensate by working harder, longer hours, and taking on more – accelerating the path to burnout.
4. Higher expectations with less support
Younger workers face a gap between expectations and reality:
- Entered workforce during or after 2008 financial crisis
- Promised that education and hard work guarantee success
- Reality of stagnant wages and limited opportunities creates disillusionment
- Expected to be “passionate” about work whilst wages don’t cover living costs
- Less access to mentorship as workplace relationships have become more transactional
5. Mental health awareness paradox
Awareness doesn’t equal support:
- Younger workers more aware of mental health, more likely to recognise burnout symptoms
- But also more likely to feel shame about struggling despite “having it easier” than parents
- Workplace mental health support often designed for crisis intervention, not prevention
- Corporate wellness programmes often token gestures rather than systemic solutions
6. Social comparison and performance pressure
The Instagram effect on careers:
- Constant exposure to peers’ curated career highlights creates comparison anxiety
- LinkedIn culture of “hustle” and “grind” normalises overwork
- Fear of being left behind drives unsustainable work patterns
- Imposter syndrome heightened by social media representation of success
Signs of burnout to watch for
Burnout symptoms aren’t always obvious, especially in younger workers who may hide struggles to appear capable. Understanding the signs of burnout helps managers intervene before crisis point.
Physical symptoms:
- Chronic fatigue that doesn’t improve with rest
- Sleep disruption – insomnia or oversleeping
- Frequent illness due to weakened immune system
- Headaches and muscle tension, particularly neck and shoulders
- Digestive issues and changes in appetite
- Skin problems or worsening of existing conditions
Emotional and psychological symptoms:
- Cynicism and negativity about work that wasn’t present before
- Feeling detached from work, colleagues, and outcomes
- Irritability and shortened temper
- Anxiety especially Sunday evenings or before work
- Reduced satisfaction even from tasks previously enjoyed
- Sense of helplessness or being trapped
- Difficulty concentrating or “brain fog”
Behavioural changes:
- Procrastination on tasks that were previously manageable
- Withdrawal from colleagues and social activities
- Increased absence or frequent sick days
- Working excessive hours but getting less done
- Mistakes and missed deadlines uncharacteristic for the person
- Neglecting self-care – poor eating, no exercise, increased substance use
Performance indicators:
- Declining quality of work output
- Missed deadlines that were previously met
- Reduced creativity and problem-solving ability
- Difficulty making decisions or second-guessing constantly
- Lower engagement in meetings and discussions
- Reduced initiative – no longer volunteering for projects or suggesting ideas
Important note: One or two symptoms might just indicate a busy period or temporary stress. Burnout is characterised by multiple symptoms persisting over weeks or months despite rest periods.
The business cost of ignoring burnout
For business leaders, preventing burnout at work isn’t just ethically right – it’s financially essential.
Direct costs:
Lost productivity
- Burnt-out employees present but unable to perform effectively (“presenteeism”)
- On average, 21.6 days lost per case of work-related stress
- Reduced quality requiring additional review and correction time
- Projects delayed when key team members are operating below capacity
Recruitment and turnover
- Replacing an employee costs 50-200% of their annual salary
- Loss of institutional knowledge when experienced employees leave
- Training costs for replacements
- Time investment from other team members during onboarding
- Team disruption affecting overall performance
Absence costs
- With 21% of workers needing time off for stress-related reasons, absence costs mount rapidly
- Temporary coverage costs or overtime for remaining staff
- Administrative burden of managing absences
- Potential need for temporary staff
Indirect costs:
Team morale and culture
- Burnout is contagious – one burnt-out team member affects colleagues
- Resentment builds when remaining staff cover absent colleagues
- Trust erodes when employees feel unsupported
- Talented performers look elsewhere when they see colleagues burning out
Innovation and growth
- Burnt-out teams don’t innovate or take creative risks
- Problem-solving ability declines
- Customer service suffers
- Competitive advantage erodes
Reputation damage
- Glassdoor and social media mean burnout cultures become public knowledge
- Difficulty attracting talent when employer brand suffers
- Client relationships affected by staff turnover
- Potential regulatory scrutiny if stress-related claims arise
The generational cost multiplier:
When younger workers burn out and leave, businesses lose:
- Employees trained for the future, familiar with emerging technologies
- Diverse perspectives and fresh thinking
- Potential future leaders before they develop
- Connection to younger customer demographics
- Investment in graduate programmes and entry-level training
Preventing burnout at work: what actually works
Generic wellness programmes don’t prevent workplace burnout. What works requires addressing root causes, particularly for younger workers.
1. Genuine flexibility, not just policy
What doesn’t work:
- Flexible working policies that require manager approval for every request
- “Core hours” that still demand 9-5 presence most days
- Remote work allowed but culture that rewards office presence
What does work:
- Results-focused management measuring output, not hours or presence
- Asynchronous work practices allowing people to work when they’re most effective
- True flexibility on location without performance assumptions
- Four-day weeks or compressed hours when possible
- Respecting boundaries – no expectation of evening or weekend responses
Why it helps younger workers:
Flexibility allows management of financial pressures (reduced commuting costs), better work-life integration, and ability to work in ways that suit individual energy patterns.
2. Financial wellness support
Recognise financial stress drives burnout:
- Fair pay that actually reflects cost of living, particularly in expensive cities
- Regular reviews ensuring salaries keep pace with inflation
- Financial education and support programmes
- Help with housing costs through relocation support or flexible working reducing commute costs
- Student loan support or other benefits recognising financial pressures unique to younger workers
3. Clear career pathways and development
Combat uncertainty with clarity:
- Transparent progression frameworks showing realistic timelines
- Regular development conversations separate from performance reviews
- Investment in training and skill development
- Mentorship programmes connecting younger workers with experienced colleagues
- Project opportunities allowing growth and visibility
4. Protect time and boundaries
Create structural barriers to overwork:
- No out-of-hours communication policies actually enforced
- Meeting-free days or protected focus time
- Mandatory breaks and lunch times away from desks
- Annual leave tracking ensuring people actually take holidays
- Disconnection periods where systems shut down after hours
Leadership must model this:
If senior leaders send emails at midnight, policies are meaningless. Leaders must visibly respect boundaries.
5. Manageable workloads
Burnout often comes from simply too much work:
- Regular workload reviews checking capacity against assignments
- Permission to say no or negotiate timelines
- Additional resources when workload increases
- Realistic deadlines with buffer for unexpected challenges
- Prioritisation support helping identify what actually matters
6. Psychological safety and support
Create environment where struggles can be discussed:
- Manager training in recognising and responding to burnout signs
- Regular check-ins focused on wellbeing, not just work output
- Normalised mental health conversations through leadership transparency
- Access to professional support – counselling, coaching, occupational health
- Flexible sick leave for mental health without stigma or interrogation
7. Community and connection
Combat isolation and disconnection:
- Team social activities (but make them optional and outside work hours)
- Peer support networks and communities of practice
- Cross-functional collaboration reducing siloed working
- Onboarding that builds relationships, not just processes
- Physical spaces that encourage connection when teams are together
Creating burnout-resistant workplaces
Preventing burnout at work requires more than individual interventions – it requires designing workplaces and cultures that inherently resist burnout.
The role of physical environment
Your workspace directly impacts burnout risk. Design elements that help:
Natural light and views
- Reduces fatigue and supports circadian rhythms
- Improves mood and energy levels
- Combats the physical drain of screen-intensive work
Variety of work settings
- Quiet focus areas when concentration is difficult
- Collaborative spaces for energising team interaction
- Comfortable breakout areas for genuine breaks
- Private spaces for calls or moments when overwhelm hits
Temperature and air quality
- Control over personal environment reduces stress
- Fresh air and good ventilation support cognitive function
- Comfort means less physical drain adding to mental exhaustion
Biophilic design
- Plants and natural materials reduce stress
- Connection to nature supports wellbeing
- Softer environments feel less institutional and pressured
Flexible layouts
- Ability to change workspace based on task or mood
- No assigned seating reduces territorial stress
- Spaces that accommodate different working styles
The cultural foundation
Environment alone doesn’t prevent burnout – culture is crucial:
Leadership accountability
- Leaders measured on team wellbeing, not just output
- Burnout prevention integrated into business strategy
- Resources allocated to wellbeing, not just lip service
Sustainable pace as standard
- Sprints followed by recovery periods
- Celebrating sustainable performance, not heroic overwork
- Promotion based on outcomes and values, not just hours worked
Open communication
- Regular team discussions about workload and pressure
- Safe channels for raising concerns
- Transparent decision-making reducing uncertainty
Collective responsibility
- Team members looking out for each other
- Peer support normalised and encouraged
- Shared ownership of maintaining healthy workplace

The path forward
Workplace burnout in the UK isn’t inevitable. The generational divide in burnout rates proves this – if older workers can experience decreasing stress whilst younger workers face increasing pressure, the problem isn’t individual resilience. It’s systemic workplace design.
For business leaders:
- Recognise that losing talented younger workers to burnout costs more than preventing it
- Implement genuine flexibility that addresses root causes, not surface symptoms
- Create workplaces where asking for support isn’t seen as weakness
- Measure success by sustainable performance, not burnout-inducing overwork
For younger workers:
- Recognising burnout symptoms early isn’t weakness – it’s wisdom
- Your generation faces legitimately different pressures than previous ones
- Prioritising your wellbeing isn’t selfish – it’s essential
- The right workplace will support your success without demanding burnout as the price
The Mental Health UK data is clear: 91% of UK adults experiencing high stress represents a crisis, not a new normal we should accept. The generational divide shows us that workplace factors, not individual factors, drive these patterns.
Creating burnout-resistant workplaces isn’t just morally right – it’s the only sustainable path forward for UK businesses.
