High performance is celebrated in most organisations. It is rewarded, promoted, spotlighted. The people who deliver consistently and raise performance standards are often viewed as the safest pair of hands in the room.
Yet stress in the workplace frequently accumulates most quietly in those very individuals because high performance and chronic stress share many of the same behavioural drivers.
For HR and L&D teams, understanding that overlap is essential if organisations want results that last longer than a quarter.
Stress in the Workplace Doesn’t Always Look Like Struggle
When we talk about stress, we often imagine a visibly overwhelmed individual like John. John is missing deadlines; he’s snapping in meetings and dramatically hurling a stapler across the office while muttering about spreadsheets and caffeine.
In reality, your stressed-out John probably looks perfectly fine. This is because chronic stress can be far more subtle.
It can look like:
- The person who answers emails instantly at all hours
- The manager who never pushes back on unrealistic timelines
- The team member who absorbs extra work without complaint (sounds like John…)
- The high achiever who struggles to delegate because standards matter
From the outside, nothing appears wrong. John’s performance remains consistent, deadlines are met, and standards stay high, so there is little to prompt concern.
Internally, the picture is different. Recovery time gradually shortens, mental load becomes heavier and decisions that once felt straightforward begin to require more effort. The nervous system stays quietly activated, sustained by cortisol and adrenaline that were designed for brief moments of threat rather than ongoing operational pressure.
The body and brain are remarkably adaptable, but they are far less forgiving when the stress response is never properly allowed to reset.
The Overlap Between Excellence and Overextension
Many high performers are driven by ownership and a genuine desire to solve problems and uphold strong standards. Those qualities are invaluable, but they can quietly become pressure points when expectations keep rising, and boundaries aren’t clear.
Research from occupational psychology and workplace wellbeing studies suggests that people who are highly conscientious and strongly motivated by achievement can be more susceptible to work-related stress when the environment constantly rewards extra effort without pause or reset. In cultures where “going the extra mile” quickly becomes the baseline expectation, that susceptibility only grows.
In other words, stress in the workplace doesn’t become normal because people are weak. It becomes normal because effort beyond a boundary is continually reinforced and rewarded. The danger isn’t ambition, it’s accumulation.
What is less obvious is how that pressure can subtly change behaviour. As mental energy depletes, people naturally begin to conserve it. Recent studies have linked sustained occupational stress to an increase in what researchers call knowledge hiding, which is the tendency to withhold information, delay sharing expertise or avoid collaborative exchanges that might generate additional demands.
It makes sense that when someone feels stretched, guarding time and cognitive bandwidth can feel like self-preservation, especially when you’re someone who loves to go the extra mile. But over time, these small acts of withdrawal can weaken trust and collaboration across a team. The very people who once fuelled collective performance may begin to pull back, not because they care less, but because they are running low.
So, the danger is not ambition, it’s accumulation.
Why Managers Often Miss the Signs
Many leaders were promoted precisely because they could operate at full throttle for prolonged periods without visibly combusting. Their coping strategy was simple: work harder, stay later, deliver anyway. It worked for them, so it quietly became the template for everyone else.
When a high performer begins to show early signs of strain, perhaps a shorter fuse in meetings or thinking that feels more reactive than strategic, it is often brushed off as a busy spell. After all, this is what high standards look like. Right?
Without a working understanding of stress, managers tend to reach for encouragement rather than adjustment. A well-meaning “You’ve got this” replaces a more useful conversation about capacity.
This is exactly where L&D earns its keep.
The Organisational Cost of Chronic Stress
Chronic stress in the workplace can affect the following:
- Cognitive flexibility
- Creativity and innovation
- Risk assessment accuracy
- Emotional regulation
- Decision quality
We have kept this list short and not especially sweet, but unmanaged stress does not politely limit itself to a few bullet points. Presenteeism, for example, where people are physically at work but operating well below capacity. In fact, work–related stress, depression and/or anxiety have accounted for 51 % of all working days lost due to ill health in 2024/25, reinforcing that stress-related conditions are the largest contributor to absence in the workplace.
So, when stress is left unchecked, organisations tend to pay twice. First, in the slower thinking, softer focus, and heavier collaboration. Then in the empty chair.
Sustainable Performance Is a Learned Skill
Resilience is a great defence against stress, but for some reason,n it’s been given the ‘it’ treatment. “Either you’ve got it, or you don’t got it”, but that’s not right at all. A lot of resilience is shaped by the environment people are working in every day. Leadership behaviour, workload expectations, psychological safety, reward systems and clarity of priorities all signal what “having it” looks like.
So, when we say good learning has got the power, we mean it.
Whilst HR can write policies and leaders can set targets, learning is what shapes behaviour at scale. It helps leaders and their teams recognise the difference between healthy stretch and chronic overload. It gives people the language to have early conversations about capacity without turning them into performance interrogations, and it reframes recovery as a strategic necessity rather than a personal indulgence. Together, these shifts contribute to a more resilient and ultimately more successful organisation.
That is exactly where targeted, behaviour-focused learning like ours makes the difference. When stress literacy, leadership modelling and sustainable performance are embedded into development programmes, resilience stops being a buzzword and starts becoming an operational reality.

We know, a bit of a plug, but stick with us, we’ve seen what happens when learning lands. Our new Resilience Essentials provide realistic and funny scenarios that stick, practical takeaways that change behaviours. Because sustainable performance isn’t about working harder. It’s about working smarter, without losing your mind in the process.
