In many workplaces, stress doesn’t always show up where you expect it.
It’s easy to notice when someone is disengaged or underperforming. But what about the employee who is still delivering, still showing up, still exceeding expectations?
Often, that’s exactly where stress hides best.
The South African Context: Pressure Is the Norm
For many professionals in South Africa, stress isn’t just about work.
It’s layered.
- Ongoing cost-of-living pressures
- Load shedding and infrastructure challenges
- Safety concerns and long commutes
- Supporting extended family or multiple dependents
- Job security
Add workplace demands to this, and many employees are operating under constant pressure even if they appear to be coping.
And in high performers, that pressure is often internalised.
How Stress Impacts Decision-Making
One of the most overlooked effects of stress is how it impacts the way people think.
When someone is under prolonged stress:
- Decision-making becomes reactive rather than strategic
- Focus narrows, making it harder to see the bigger picture
- Risk tolerance shifts, either becoming overly cautious or impulsive
- Mental fatigue leads to slower processing and reduced clarity
In leadership roles especially, this can quietly impact team direction, communication, and overall performance.
So while output may still look “good,” the quality of thinking behind it may be compromised.
Why High Performers Are Harder to Read
High performers are often the hardest to read because the very traits that make them successful also make their stress less visible. They are highly responsible, deeply results-driven, and often reluctant to show vulnerability. Over time, they become skilled at pushing through pressure rather than pausing to process it. In leadership roles, this is compounded by something less often spoken about, the cognitive weight of consequence. These individuals are not only managing their own workload, but are constantly carrying the impact of their decisions on teams, revenue, clients, and company direction. This sustained mental load doesn’t always lead to immediate burnout; instead, it can quietly shift how they think, leading to decision fatigue, reduced creativity, and a tendency toward safer, more conservative choices. The insight here is that stress at this level doesn’t always show up as collapse, it often shows up as constraint. And when leaders begin to operate in a more constrained way, the ripple effect can influence innovation, culture, and growth across the entire organisation.
Subtle Signs to Look Out For
Stress in high performers is often quieter, but there are signals:
Increased irritability or shorter patience
Someone who is usually calm and composed may start reacting more quickly or more sharply than usual. This isn’t necessarily about attitude, it’s often a sign of reduced mental capacity. When someone is under sustained pressure, their ability to regulate emotions becomes thinner, and small frustrations can feel disproportionately overwhelming.
Withdrawal from team interaction
High performers who are stressed may begin to pull back by contributing less in meetings, avoiding casual conversation, or choosing to work more independently. This can easily be mistaken for focus, but often it’s a sign that they are trying to conserve energy or avoid additional demands.
Overworking and inability to switch off
You may notice them sending emails late at night, always being “on,” or struggling to take proper breaks. While this can look like dedication, it often reflects an internal pressure to stay on top of everything and a fear of things slipping if they pause. Over time, this erodes recovery and compounds stress.
Perfectionism or over checking work
A shift toward excessive attention to detail, reworking tasks multiple times, or struggling to “let go” of deliverables can signal underlying stress. When cognitive load is high, people often try to regain control by tightening standards, even when it’s not necessary.
A noticeable shift in energy or engagement
This might show up as someone who is still delivering, but feels different. Less enthusiastic, less present, or more mechanical in their interactions. Energy becomes inconsistent, they may have moments of high output followed by visible dips in engagement.
Difficulty making decisions or second-guessing themselves
One of the most important signals, especially in leadership roles. Stress impacts cognitive clarity, and decisions that were once made with confidence may now take longer, require more validation, or be avoided altogether. This is often a sign of decision fatigue rather than lack of capability.
These are easy to miss, especially when performance hasn’t dropped significantly.
What You Can Do as a Leader
Supporting your team doesn’t mean having all the answers, it starts with awareness and small, intentional actions.
1. Create Space for Real Conversations
Make it clear that it’s okay to not always be “fine.” Sometimes a simple check-in can open the door.
2. Normalise Breaks and Boundaries
High performers often don’t stop unless given permission. Model this behavior from the top.
3. Encourage Small Resets During the Day
Even short moments to pause, stepping away, taking a breath, or resetting physically can make a difference.
4. Offer Access to Support
Whether it’s internal resources, EAP programmes, or external wellness partners, make support visible and accessible.
5. Watch for Patterns, Not Just Performance
Look beyond output. Changes in behavior often tell a deeper story.
Stress doesn’t always look like falling behind, sometimes it looks like holding everything together, quietly. And often, the people you rely on the most are the ones least likely to say they need support. Creating a workplace where those individuals feel seen, supported, and able to pause, even briefly, can make all the difference.
Addressing stress isn’t about adding more to already full plates, but rather embracing the idea that change happens little by little, through small, consistent shifts that support people in a meaningful way. Creating moments to pause, encouraging healthier boundaries, and offering simple ways to reset can have a far greater impact over time than any once-off intervention.
Because when it comes to stress, it’s often the smallest changes that create the biggest difference.
