Why creating a brain-friendly workplace is becoming a leadership and performance issue 

Most organisations depend on people to think well. 

We need leaders to exercise judgment, managers to prioritise, teams to solve problems, and people to learn, adapt and collaborate. 

Yet we have created workplaces that often make those things surprisingly difficult. 

Back-to-back meetings. Constant notifications. Crowded calendars. Multiple priorities. Competing change initiatives. Pressure to respond quickly. An expectation of constant availability. And now, an accelerating stream of AI-generated information, options and outputs. 

The Center for Brain Health argues that many workplaces unintentionally undermine the very brainpower they depend on. Stress, cognitive overload and depleted attention can erode trust, creativity and innovation. 

Your brain is a business asset 

We tend to think about brain health as an individual wellbeing issue. Manage stress, exercise, take breaks and get enough sleep. All good advice. 

Brain health is also clearly a performance issue. Our capacity for sustained attention, judgment, emotional regulation, creativity and decision-making is not unlimited. 

All these capabilities are affected by the conditions in which we ask people to work. 

And framing this as an individual issue risks putting the responsibility on individuals to cope with working environments that organisations themselves have created. 

At Mantle we would argue that those conditions have become increasingly demanding. 

Microsoft’s workplace telemetry provides a striking illustration. Among its highest-volume users, employees received a meeting, email or chat interruption roughly every two minutes during the working day. Across a 24-hour period, that amounted to 275 interruptions. Sixty percent of meetings for the highest-volume meeting users were ad hoc rather than scheduled. 

Then we wonder why people struggle to concentrate. 

The answer isn’t to become better at multitasking. Constant task switching has cognitive costs, interfering with attention and working memory. 

The hypothesis is that we have designed work around an unrealistic assumption that the brain can absorb almost unlimited inputs while continuing to perform at its best. If that is the case you might expect quite a bit of push back from employees. It’s true that can show up to a degree in engagement surveys and exit interviews but its usually mentioned with restraint. 

There is another complication. 

Busyness has become a signal of value. 

A full calendar suggests importance. Rapid responses demonstrate commitment. Attending lots of meetings shows engagement. Working long hours signals dedication. 

Harvard Business Review has called this a “culture of busyness”: the tendency to confuse activity with achievement and to reward visible effort even when it doesn’t improve productivity. This creates an uncomfortable paradox for leaders. 

Most leaders understand intellectually that prioritisation matters. Strategy, after all, is partly about deciding what not to do. Yet organisational life often rewards the opposite. 

We add another initiative without stopping an existing one. We accept another meeting because declining it feels difficult. We respond immediately because responsiveness is visible. We fill the space created by efficiency with more activity. 

Soon, we become extremely busy doing things that may not matter very much. 

That isn’t simply a personal productivity problem. 

It’s a leadership problem. 

A brain-friendly workplace requires courageous leaders to shift the conversation from: 

“How much are we doing?” 

to: 

“Where are we creating the greatest impact?” 

The leader’s brain matters too 

There is a temptation to think about brain-friendly workplaces as something leaders create for other people. That misses half the issue. 

Leaders operate under exactly the same cognitive constraints as everyone else, often while facing greater demands. 

Their attention moves between operational decisions, people issues, strategy, customers, financial pressures, organisational change and stakeholder expectations. The working day can become a sequence of meetings punctuated by attempts to catch up with everything else. 

And yet we expect leaders to see the bigger picture. 

To notice patterns. 

To make good judgments. 

To challenge assumptions. 

To think beyond the immediate problem. 

That requires cognitive space. 

A leader whose attention is continuously fragmented may still look highly productive. Their calendar may provide impressive evidence of activity. But activity and effectiveness are not the same thing. 

Leadership sometimes requires doing something that can feel almost irresponsible or career limiting in a busy organisation: 

Stopping. Thinking. Reflecting. 

It might mean protecting an hour without meetings. Walking away from the screen to think through a problem. Reading something slowly. Having a conversation without simultaneously checking a device. Or resisting the pressure to make an immediate decision. 

These behaviours don’t always look like work. But they may be some of the most important work a leader does. 

Research highlighted by the Center for Brain Health and others supports something that many of us intuitively know: continuously powering through can lead to fatigue, distraction and poorer decision-making, while genuine breaks from information intake can help restore mental energy. 

But slowing down carries social risk 

If this makes sense, why don’t more leaders do it? 

Because work isn’t only cognitive. 

It’s social. 

People continually interpret signals about status, belonging, approval and threat. 

Consider the manager who says: 

“We have too many priorities.” 

Or: 

“I don’t think I need to attend this meeting.” 

Or: 

“We should stop this initiative.” 

Or simply: 

“I need some time to think before answering.” 

Those can be surprisingly courageous statements. 

Because the perceived social risk is real. 

What if I look uncommitted? 

What if everyone else seems to be coping? 

What if challenging this priority damages my reputation? 

What if an empty space in my calendar looks like I’m not busy enough? 

What happens if I stick my head up and question how we work around here? 

This is where brain-friendly workplaces intersect with psychological safety. 

The Center for Creative Leadership defines psychological safety as the belief that people will not be punished or humiliated for speaking up with ideas, questions, concerns or mistakes. 

Psychological safety isn’t about making work comfortable or removing accountability. 

It is about making candour possible. 

If leaders want people to challenge unnecessary work, question priorities, identify problems and admit that capacity has been exceeded, they need to make it socially safe to do so. 

And that starts with what leaders themselves do. 

Leaders are always role modelling 

People pay attention to behaviour, not just messages. 

A leader can encourage people to protect their wellbeing while sending emails at midnight. They can talk about focus while scheduling back-to-back meetings. 

They can ask people to prioritise while continually introducing new priorities. 

They can encourage challenge while becoming defensive when challenged. 

They can tell people to take breaks while never appearing to take one themselves. 

The unintended message is obvious: 

Do what I say…but if you want to succeed here, watch what I do. 

Creating a brain-friendly workplace therefore requires more than a wellbeing programme or a few meeting-free afternoons. 

Leaders have to model it. 

That might mean visibly protecting thinking time. Declining low-value meetings. Taking proper breaks. Asking whether something genuinely needs to be done. Giving people permission not to respond immediately. Being open about uncertainty. Changing their mind when better information emerges. 

And perhaps most importantly, demonstrating that: 

Thinking is work. 

Then along comes AI 

AI adds another dimension to all of this. 

But AI isn’t the fundamental problem. 

It is an amplifier. 

AI can dramatically increase our ability to create, analyse, communicate and access information. Used well, it can remove low-value cognitive work and give people more capacity for higher-value thinking. 

But it can also create more. 

More information. More content. More possibilities. More decisions. More expectations. More change. 

Wharton professor and neuroscientist Michael Platt argues that while AI can generate outputs at extraordinary speed, determining relevance, weighing competing priorities and recognising when context requires judgment rather than optimisation remain human responsibilities. As access to information becomes less of a constraint, interpretation, coordination and judgment become increasingly important. 

Deloitte’s 2026 Human Capital Trends research reinforces the scale of the challenge. One-third of surveyed workers globally reported experiencing 15 major changes in the previous year. In New Zealand, 51% of respondents identified capability and resource constraints as their biggest barrier to adapting to change. Deloitte warns that this means change competes directly with day-to-day delivery, increasing the risk that AI adds pressure rather than improving results. 

That is why simply adding AI to existing ways of working isn’t enough. 

We risk using extraordinary technology to help already overloaded people become overloaded faster. 

The opportunity is to use AI to create capacity, and then resist the temptation to immediately fill that capacity with more activity. 

Useful things brain-friendly leaders can do differently 

There is no single neuroscience trick that creates a brain-friendly workplace. 

But there are some useful leadership disciplines.

1. Protect attention
   Treat attention as a scarce organisational resource. Question unnecessary meetings, interruptions and communications. Create periods when people can concentrate without being expected to be constantly available.

2. Create clarity
   Cognitive overload isn’t only caused by volume. Ambiguity consumes capacity too. Help people understand what matters most, and what matters less.

3. Prioritise through subtraction
   Adding priorities is easy. Leadership is also about stopping things. When something new arrives, ask: What will we stop, pause or deprioritise to create room for it?

4. Make challenge socially safe
   Encourage people to question priorities, raise concerns, admit uncertainty and disagree respectfully. Don’t ask for candour and then punish people when they provide it.

5. Create space for thinking and recovery
   Don’t treat every empty space in the calendar as unused capacity. Reflection, recovery and deep thinking are part of knowledge work, not an escape from it.

6. Model it yourself
   Perhaps the hardest discipline of all. Look at your own calendar, behaviour and expectations. What are they teaching other people about what leadership looks like?

Maybe we need a different picture of effective leadership 

Creating a brain-friendly workplace isn’t about making work easier. 

It is about making better performance possible. 

Organisations will continue to face demanding customers, financial pressures, deadlines, uncertainty, technological disruption and rapid change. Leaders cannot remove those realities. 

But they can avoid unnecessarily adding to the cognitive burden. 

And they can challenge workplace practices that have gradually become normal despite working against the outcomes organisations say they want. 

That requires leaders to ask some uncomfortable questions. 

What does my calendar say about what I value? 

Do I reward impact or visible busyness? 

What happens when someone tells me we’re doing too much? 

When did we last stop something rather than start something? 

Do people around me feel safe enough to challenge my priorities? 

And perhaps most importantly: 

Am I creating enough space to do the thinking my role actually requires? 

The future of work will undoubtedly involve better technology and increasingly capable AI. 

But technology doesn’t remove the need for human attention, judgment, creativity, relationships and courage. If anything, it may make those capabilities more valuable. 

At Mantle, we think this creates an important leadership challenge. 

Developing better leaders isn’t only about adding more skills, tools and knowledge. It is also about helping leaders understand the conditions that enable them, and the people around them, to perform at their best. 

Sometimes leadership development is about adding capability. Sometimes it is about creating the space to use the capability we already have.
