Why work-life balance matters: What leaders need to know
For years, work-life balance has been a growing focus, particularly in an ‘always-on’ world of technology and constant connectivity.
In work cultures where back-to-back meetings are the norm and long hours can be mistaken for productivity, pressure and stress can quickly lead to burnout.
Work-life balance may be the solution we are searching for, but only when leaders understand what it really means and take action to make it possible.
Employee expectations are changing. What was once viewed largely as a personal preference is increasingly becoming a defining factor in how people assess their working lives - and whether or not they choose to stay.
In Randstad’s 2026 Workmonitor, 46% of workers globally cited work-life balance as a key reason for staying in their current role, making it the leading retention factor, compared with just 23% who cited pay and benefits.
For leaders, this means how people work matters not only in relation to personal wellbeing, but to an organisation’s ability to retain its talent and sustain performance.
What does work-life balance actually mean?
There is no single formula for a healthy work-life balance. It does not necessarily mean dividing the day equally between work and everything else, nor does it mean working fewer hours at all costs.
For one person, balance might mean finishing on time to collect their children from childcare or school. For another, it could mean having flexibility to study, pursue interests, or manage caring responsibilities. For someone at the beginning of their career, it might mean building ambition without allowing work to consume their identity.
What matters is whether work is sustainable alongside the rest of life.
This includes not only the time spent working, but also the mental space it occupies. If you are physically at home but worrying about work, checking messages late into the evening or thinking about tomorrow’s deadlines, the boundary between work and personal life has already become compromised.
As a leader, the crucial question is: Are people able to perform well while maintaining their mental and physical wellbeing over the long term?
Why should leaders care?
For leaders, work-life balance is not simply an employee wellbeing issue. It has significant consequences for who stays, how effectively people work and whether performance can be sustained over time.
Retaining the talent you need
When work consistently encroaches on personal life, employees may eventually decide the trade-off is no longer worth making. Recent CIPD research found that around 1.1 million UK employees left a job in the previous year because of a lack of flexible working. The figure was even higher among younger workers, with 8% of 18–24-year-olds and 7% of 25–34-year-olds saying they had left a job due to a lack of flexibility.
That makes work-life balance a talent issue as much as a wellbeing one. For organisations already competing for skills, losing experienced people - or struggling to attract the next generation of talent - carries a substantial cost.
When burnout impacts performance
The relationship between excessive demands and performance is equally important. Sustained pressure and workload can affect concentration, motivation, absence and the quality of work people are able to produce.
Deloitte estimates that poor mental health costs UK employers £51 billion a year, with presenteeism - being at work while unwell and less productive - accounting for the largest share of that cost.
This is where leaders need to look beyond the number of hours people are working. A team may appear productive because people are working late, answering messages out of hours and pushing through periods of intense demand. But if that pace cannot be maintained, apparent productivity can become a false economy.
Better balance means better productivity
The argument for work-life balance is not that people should work less and expect the same results. It is that sustainable performance is likely to be stronger than performance driven by exhaustion.
A study by the Corporate Executive Board, based on research involving more than 50,000 global workers, found that employees who believed they had a good work-life balance worked 21% harder than those who did not.
More recent CIPD research points in a similar direction. In its 2025 study of flexible and hybrid working, 41% of employers said increased home or hybrid working had improved productivity or efficiency, compared with 16% who said it had reduced productivity.
The lesson for leaders is not that there is one perfect way to work. It is that productivity should not be confused with constant availability. Creating the conditions for people to recover, focus and manage the demands of work alongside the rest of their lives is an investment in performance, rather than a compromise to it.
Balance is a leadership responsibility
Work-life balance is sometimes framed as an employee responsibility: set boundaries, take breaks, use your annual leave and stop checking emails.
Those things can help. But they only go so far.
Leaders influence the conditions in which people work. They shape expectations around working hours, responsiveness, workload and availability. They also determine, often unintentionally, which behaviours are rewarded.
A leader who regularly sends emails late at night may not explicitly expect an immediate response, but their team may interpret it that way. A manager who praises someone for working through a holiday can unintentionally create a culture in which taking time off feels like a lack of commitment.
Good leadership therefore means looking beyond individual resilience to the systems and behaviours surrounding work.
Leadership starts before you have a leadership title
This matters for established leaders, but it also matters for those at the beginning of their leadership journey.
Deloitte’s 2026 Gen Z and Millennial Survey found that work-life balance is the top career goal for both Gen Z and Millennials in the UK. At the same time, 84% of Gen Z respondents and 73% of Millennials said they were interested in pursuing leadership roles at some point in their careers. Yet stress and burnout, excessive responsibility and concerns about work-life balance were among the leading barriers they associated with becoming a leader.
Tomorrow’s leaders are therefore already forming their expectations of what good work looks like - and what good leadership looks like alongside it.
Five ways leaders can support better work-life balance
Creating a healthier approach to work does not require leaders to lower expectations. It requires them to be intentional about the conditions in which people are expected to meet them.
1. Set clear expectations around availability
Be explicit about when people are expected to be available and what genuinely requires an immediate response. Avoid creating an ‘always-on’ culture where employees feel they need to monitor emails and messages outside their working hours.
2. Talk about workload, not just wellbeing
Asking how someone is doing is important, but it should not replace conversations about what is actually being asked of them. Regularly review priorities, capacity and deadlines, and be prepared to remove or reprioritise work when demands become unrealistic.
3. Give people autonomy where you can
Flexible work is not simply about where someone works. Where roles allow it, give people greater control over when and how they work, while maintaining clear expectations around outcomes and accountability.
4. Model the behaviour you want to see
Leadership is communicated through behaviour as much as words. Take breaks, use annual leave and respect other people’s time. If leaders consistently work late or send messages at all hours, employees may interpret that as an expectation - regardless of what the policy says.
5. Make balance part of the culture
Work-life balance should not depend on having a particularly supportive manager or being confident enough to ask for an exception. Consider whether your policies, processes and everyday team practices genuinely support sustainable ways of working, and ask employees what would make the biggest difference.
Final thoughts
Ultimately, work-life balance is not about creating a softer approach to work or lowering expectations. It is about creating the conditions in which people can perform well, develop their careers and sustain that performance over the long term.
For established leaders, that means examining the culture and systems they have the power to influence. For those still developing their leadership skills, it means recognising that leadership starts with the behaviours they choose to model - long before they have a team of their own.
