Every business has one.
The employee who never misses a deadline. The person who always says yes. The individual who can be relied upon to solve problems, step in during a crisis, and keep everything moving.
They’re often described as the backbone of the business.
But what if your highest performer is also your biggest risk?
It may sound counterintuitive, but some of the most capable and committed employees are also the most likely to experience stress, burnout, and long-term exhaustion.
The very qualities that make someone a high performer can also place them at risk.
The Problem With High Performers
High performers are often seen as safe hands.
Because they consistently deliver results, managers can unintentionally place more responsibility on their shoulders. They become the person who takes on the extra project, supports colleagues, and picks up the pieces when challenges arise.
Over time, this can create a dangerous cycle.
The more capable an employee appears, the more work they receive.
And because they have built a reputation for reliability, many high performers struggle to say no.
They Often Work Longer Hours
Many high-performing employees place significant pressure on themselves.
They may work through lunch, stay late, check emails in the evening, or continue working while on holiday. They aren’t necessarily being asked to do this; they often feel personally responsible for maintaining high standards and delivering results.
Initially, this dedication can appear positive.
But over time, consistently working beyond healthy limits can have serious consequences for both physical and mental wellbeing.
The issue isn’t simply the number of hours worked. It’s the lack of opportunity to recover.
They Hide Stress Better Than Most
One of the greatest misconceptions about workplace wellbeing is that people who are struggling will make it obvious.
In reality, many high performers become experts at masking stress.
They continue to deliver results, attend meetings, and maintain their usual standards. They don’t want to let their colleagues down, appear incapable, or be perceived as unable to cope.
As a result, managers often miss the warning signs.
By the time stress becomes visible, the individual may have been struggling for months.
They Avoid Taking Time Off
High performers frequently feel guilty about taking annual leave or stepping away from work.
Some worry that work will pile up in their absence. Others fear they are letting their team down or believe no one else can handle certain responsibilities.
The result is often a lack of meaningful rest and recovery.
Ironically, the people who need time away from work the most are often the least likely to take it.
They Carry More Responsibility Than Anyone Realises
High performers often become the “go-to” person within an organisation.
They hold valuable knowledge, maintain key client relationships, and manage important processes that others may not fully understand.
This creates a hidden business risk.
If that employee becomes unwell, experiences burnout, or leaves the organisation, the impact can be significant.
Projects may stall. Customers can be affected. Teams can become overwhelmed. Valuable knowledge may walk out of the door.
For many businesses, the absence of one key individual can create a ripple effect across the entire organisation.
Burnout Doesn’t Happen Overnight
Burnout rarely occurs because of one particularly busy week.
It usually develops gradually.
A little extra work becomes normal. Annual leave goes unused. Stress levels increase. Boundaries begin to disappear. Recovery time becomes increasingly limited.
Eventually, even the most resilient employee reaches a point where they can no longer continue at the same pace.
At that stage, the consequences can include prolonged absence, reduced performance, mental health challenges, and in some cases, resignation.
The Cost to Businesses
The loss of a high-performing employee can be incredibly expensive.
There are the obvious costs associated with recruitment and training, but there are also less visible consequences:
- Reduced productivity
- Delayed projects
- Increased pressure on colleagues
- Loss of specialist knowledge
- Lower team morale
- Potential impact on customer relationships
For smaller businesses in particular, losing one key individual can have a disproportionate effect on performance and growth.
How Employers Can Support High Performers
Supporting high performers isn’t about asking them to lower their standards.
It’s about creating an environment where success doesn’t come at the expense of wellbeing.
This may involve encouraging annual leave, managing workloads more effectively, promoting open conversations around mental health, and ensuring employees know where support is available.
Employee wellbeing initiatives, Employee Assistance Programmes, flexible working arrangements, and access to healthcare support can all play an important role in helping employees maintain their performance in a sustainable way.
Most importantly, employers should regularly check in with their highest performers.
Because the people who appear to be coping best are often the least likely to ask for help.
Final Thoughts
High performers are invaluable to any organisation. They drive growth, inspire colleagues, and often play a critical role in business success.
But they are not invincible.
The qualities that make someone exceptional can also make them vulnerable to stress, overwork, and burnout.
The question for employers is not simply, “Who are our top performers?”
It’s also:
“Are we doing enough to protect the people we rely on most?”
At Medical Made Easy, we believe employee wellbeing should be viewed as a key part of business resilience. Supporting your people isn’t simply about helping them perform today, it’s about ensuring they can continue to thrive tomorrow.
