April marks Stress Awareness Month in the UK - a time when conversations around mental health, workplace wellbeing, and employee retention come sharply into focus. As recruiters, we spend our days speaking to professionals across industries, and one theme comes up time and time again: burnout.

But is burnout really the biggest reason employees leave their jobs? The answer is both simple and complex.

Burnout: The Symptom, Not Always the Cause

Burnout is often described as emotional, physical, and mental exhaustion caused by prolonged stress. Candidates frequently cite it as their reason for seeking new opportunities. However, in many cases, burnout is not the root cause; it’s the result of deeper workplace issues.

When we dig a little deeper with candidates, burnout tends to stem from:

• Poor leadership or lack of support
• Unmanageable workloads
• Lack of recognition or progression
• Toxic workplace culture
• Blurred boundaries between work and personal life

So while burnout is the headline, the underlying story is often about dissatisfaction, misalignment, or feeling undervalued.

What Candidates Are Really Telling Recruiters

In conversations, candidates rarely just say “I’m burned out” and leave it there. They talk about:

• Feeling constantly “on” with no time to recharge
• Being stretched across multiple roles without clarity
• A lack of autonomy or trust from management
• No clear path for career growth
• Someone leaving the business and their work being "absorbed" into the team

These insights reveal that burnout is often the tipping point - the moment someone decides they’ve had enough.

The Post-Pandemic Shift

Since the pandemic, expectations around work have shifted dramatically. Flexibility, well-being, and purpose are no longer perks; they’re priorities.

From a recruiter’s perspective, candidates are more willing than ever to leave roles that negatively impact their mental health. Burnout is less tolerated, and employees are more proactive in seeking healthier environments.

Is Burnout the Biggest Reason?

If we’re being precise, burnout is one of the most visible reasons employees leave, but it’s rarely the only one.

It acts as a catalyst. A signal. A breaking point.

In exit interviews and hiring conversations alike, burnout often sits alongside other factors like compensation, leadership, and career stagnation.

What Employers Should Take Away

Stress Awareness Month is a reminder that retention isn’t just about salaries or perks; it’s about sustainable working environments.

From what we see in the market, organisations that retain top talent tend to:

• Prioritise realistic workloads and resource planning
• Train managers to lead with empathy and clarity
• Encourage boundaries (and respect them)
• Offer genuine career development opportunities
• Create cultures where employees feel heard and valued

Final Thoughts

Burnout may not always be the root cause of employee turnover, but it’s often the loudest warning sign.

As recruiters, we see the patterns early. The candidates who come to us aren’t just looking for a new job - they’re looking for relief, balance, and a better way of working.

The question for employers isn’t just “Are our employees burning out?”
It’s “What’s causing it, and what are we doing about it?”

Because by the time burnout shows up, your best people may already be halfway out the door.

If your team are stretched, would an extra pair of hands help with the backlog and workload? Taking on a contractor to clear demand and support your employees could significantly reduce the burnout they may be feeling.
