Why people are really leaving work

More money. Better titles. Greater ambition. New opportunities. And while these factors still matter, new research suggests a far more concerning reality.

Many people are not leaving work to get ahead. They are leaving to protect their wellbeing.

New research from Careershifters, based on more than 11,500 UK professionals actively considering career change, found that the biggest drivers of career moves are not financial.

They are deeply human.

The study found that 73% of respondents said their work was negatively affecting their overall life satisfaction, while 91% said it was harming their mental health. And the leading reasons for wanting to leave were unsupportive or unhealthy work environments, poor work-life balance, and values misalignment. Pay ranked significantly lower.

That should make all organisations pause.

Because this is not simply a retention issue, nor is it a story about ambition. It is a warning sign that many workplaces are becoming increasingly difficult to sustain. And that should concern every leader.

For decades, many workplaces have been built around the belief that pressure drives performance. That long hours demonstrate commitment; constant availability signals dedication; and that resilience means enduring whatever work demands.

These assumptions became embedded in organisational culture long before wellbeing became a boardroom conversation. And in many workplaces, they continue to shape expectations today. Even in organisations that publicly speak about wellbeing.

Employees may hear messages about balance while watching leaders send emails late at night. They may be encouraged to disconnect while observing colleagues rewarded for constant availability. They may be offered wellbeing programmes while operating within workloads that leave little room to recover.

These contradictions matter. Because people pay attention to what organisations reward, not simply what they communicate. And over time, these contradictions erode trust. This is rarely about one difficult week or one demanding manager.

More often, it is cumulative. The steady erosion of energy. The quiet normalisation of stress. The feeling that work is taking more than it gives back. Eventually, people begin asking difficult questions. Is this sustainable? Is this worth the cost? What am I sacrificing to remain here?

And increasingly, many are deciding the answer is no. It’s enough.

This should challenge some of the assumptions organisations continue to make about performance, motivation, and loyalty. Because many people are no longer willing to sacrifice their health, relationships, and quality of life for workplaces that fail to support them.

This is not laziness. It is not entitlement. And it is not a lack of ambition.

It is often a rational response to environments that feel increasingly difficult to sustain.

Importantly, people are not making these decisions quickly. The Careershifters research found that nearly three quarters of respondents had been considering career change for more than a year, while one in four had been considering it for over three years.

That suggests something important. People are not impulsively walking away. They are often staying longer than they should. Trying to make things work. Hoping conditions improve. Waiting for circumstances to change. And eventually reaching a point where leaving feels necessary.

This should concern organisations because disengagement rarely appears overnight. It often begins quietly. Through exhaustion, frustration, values misalignment, through feeling unseen, and through environments where people no longer believe things will improve.

By the time someone resigns, the disengagement often started long before.

There is also a deeper question many people are now asking of their work, whether consciously or not: Does this work matter, and do I matter within it?

When the answer begins to feel unclear, something shifts. Work becomes more transactional. Energy becomes harder to sustain. And over time, people begin questioning not simply their role, but whether they can continue within an environment that no longer feels meaningful or aligned with who they are.

But meaning is not something organisations can simply create through messaging or wellbeing initiatives. It is shaped through the everyday experience of the work itself. Through workload. Through expectations, leadership behaviour, and through trust, flexibility, recognition, and psychological safety.

These are no longer ‘soft’ concerns. They are increasingly business critical.

And generational shifts are accelerating this conversation. Younger workers are openly challenging cultures that reward burnout, performative busyness, and constant visibility. They are not rejecting hard work. They are rejecting unhealthy definitions of success that come at too high a personal cost.

At the same time, many older workers are reassessing what matters later in life: health, purpose, flexibility, family, time. Across generations, people are increasingly questioning what work should provide and what they are willing to sacrifice for it.

This becomes even more significant as AI and automation continue to reshape work. As technology accelerates efficiency, organisations may feel pressure to demand even more productivity. But if human sustainability is ignored, those pressures may accelerate the very attrition organisations are trying to avoid.

The future of work cannot simply become faster. It must become smarter. And more human. This is where organisations may need to rethink their approach to wellbeing.

Many still treat wellbeing as something that sits alongside work through programmes and initiatives, leaving the design of work unchanged.

But sustainable wellbeing is not separate from work. It is created within it, through workload, boundaries, flexibility, expectations, and through leadership behaviour. Because leadership shapes the experience of work.

And that experience determines whether people stay.

The Careershifters report should act as a warning. Not because people are leaving. But because so many have been quietly trying to endure unsustainable work for far too long before finally deciding they can no longer do so.

The organisations that thrive in the future may not be those that demand the most. They may be the ones people genuinely want to remain part of. Because increasingly, people are not leaving for more money. They are leaving to protect their lives.
