Change fails when the brain feels unsafe. HR needs a more human approach

A new system lands. A reporting line shifts. Priorities change again. Employees are told the organisation needs to be agile, resilient and open to transformation. But their brains may be hearing something else: more uncertainty, more effort and less control.

Research from McLean & Company suggests this is now a serious organisational problem. Seven in 10 organisations report challenges managing change, with too many simultaneous changes named as the biggest barrier. The findings point to a gap in how many employers still approach transformation: as a programme to be rolled out rather than an experience the human brain has to process.

Instead, argues McLean & Company, organisations need to rethink change as a human and organisational capability. The central message is simple: change works better when it is designed around how people actually process uncertainty. And this means paying closer attention to the brain.

The research says even highly adaptable employees can struggle with change because resistance is a natural response to perceived threat. The brain prioritises safety and familiarity. New processes, behaviours and expectations can be read as risk, even when the change itself is positive. Change also increases cognitive load because learning new skills or adjusting habits requires more mental energy than familiar work. When expectations are unclear or reality shifts without warning, stress responses can reinforce old habits and slow adaptation. 

“Brain-friendly change” moves the conversation away from whether employees are resistant and towards what conditions make adaptation possible. Clarity, involvement, psychological safety and a stronger sense of control become practical change levers.

Too much change is now the change problem

The volume of change has become a performance issue. McLean’s research finds 70% of organisations report challenges managing change, with too many simultaneous changes identified as the leading reason. 

Many change plans still assume employees have enough capacity to take on one more transformation, system rollout or behavioural shift. But change rarely arrives in the tidy sequence suggested by project plans. Inside an organisation one programme often bleeds into another. A technology rollout can change daily work just as budgets tighten or a restructure can alter relationships while leaders are asking for faster decisions and stronger performance. The problem is this accumulated pressure placed on people who are still expected to deliver as usual.

McLean describes organisations as navigating overlapping waves of change, often before the previous ones have settled. The cumulative effect is loss of focus, weaker execution and rising emotional load. 

Brain-friendly change starts with clarity

Brain-friendly change means designing change in ways that reduce avoidable threat and cognitive overload. It does not remove uncertainty but does give people enough structure, information and involvement to keep functioning well within it.

The research identifies several human-centred outcomes from this approach: reframing change as continuous rather than episodic, designing change to support motivation, increasing employee ownership, improving transparency and normalising continuous learning. 

McLean describes resistance as the brain’s way of asking for clarity. In organisations resistance is often treated as a communications issue, a mindset problem or evidence that managers need to push harder. The neuroscience framing suggests a different reading. People may be asking, directly or indirectly: What is happening? Why now? What does this mean for my work? What do I have control over? Where can I contribute? What is still unknown?

These questions need honest answers. A polished change narrative that avoids uncertainty can create more anxiety than a clear acknowledgement of what is known and what is still being worked through.

Harrick Snow, change practice manager at Victoria University of Wellington, puts the involvement point plainly in the research: “People don’t resist what they help cocreate. Engaging employees in change and showing them how their input is shaping the outcome results in buy-in, avoiding resistance and burnout.” 

There is a useful warning here for organisations leaning heavily on top-down change programmes. Consultation that does not influence decisions quickly becomes theatre. Employees need to see how their feedback is shaping what happens next. Otherwise involvement becomes another demand on their time.

HR’s role is becoming a measure of organisational adaptability

The research finds that HR’s work is directly to organisational responsiveness. Respondents whose HR departments enable their organisations to navigate change and uncertainty were 2.1 times more likely to highly rate the organisation’s ability to change quickly at scale. 

Change at scale depends on strategy, systems, leadership behaviour and employee experience. HR has influence across all four. This means there is an opportunity to bring a more disciplined people lens into how change is prioritised and paced – asking whether the organisation has the capacity to absorb the change it is planning and mapping the cumulative employee impact across different projects. It also means helping leaders understand where lack of clarity, role confusion or weak communication may be slowing execution.

McLean argues that HR has a role at organisational level across strategy, culture and environment. In strategy HR can help leaders anticipate future needs and align priorities. In culture it can reinforce behaviours that support adaptability. In the working environment it can help design structures, systems and processes that support collaboration during change. 

HR cannot sit downstream of decisions and then be asked to “land the change”. By that stage many of the conditions that shape employee response have already been set.

Leadership behaviour shapes change fatigue

Leaders are central to whether change feels navigable or threatening. McLean finds that when leaders are highly effective at managing change, respondents are 1.6 times more likely to report that they are not experiencing change fatigue. 

The leadership task is becoming harder. Managers are often expected to translate uncertainty while experiencing it themselves. They may have incomplete information, limited capacity and teams looking to them for confidence. Avoiding difficult questions usually leaves people to fill the gaps themselves.

McLean’s research argues that leaders need to communicate what is known and what remains uncertain. They need to reinforce purpose, direction and context, then give teams enough information to understand next steps and how learning will happen as the change unfolds. 

Jennifer Moss, international speaker, journalist and author, says: “The environment and expectations have shifted, and the pace of change has accelerated. Leaders need to recognize that their own development is part of navigating this new landscape. When they hold on to old ways of doing things, it undermines progress and creates barriers for their teams.” 

This is where leadership development needs to become more responsive. Long programmes disconnected from daily pressure are unlikely to meet the moment. Leaders need help with live judgement: how to talk about uncertainty, how to prioritise, how to involve employees, how to spot fatigue and how to keep learning while work is moving.

McLean also finds that organisations embedding leadership accountability for managing change into performance management practices are 1.5 times more likely to report being able to change quickly at scale to capitalise on new opportunities. 

This suggests change leadership needs to be assessed as part of how leaders perform their roles. It should show up in expectations, feedback, development and reward. Leaders who consistently create confusion, overload or silence during change carry a business risk.

Psychological safety makes adaptation easier

Employees build resilience when change feels supported and shaped with them. Unsurprisingly, psychological safety is a central part of that because people need to ask questions, raise concerns, challenge assumptions and suggest improvements without fear of punishment.

The research says psychological safety helps employees navigate uncertainty with more confidence, contribute to solutions and strengthen collective resilience. If employees do not feel safe to say that a change is confusing, duplicative or unworkable the organisation loses valuable intelligence. Silence can look like acceptance until delivery starts to fail.

Mary Poffenroth, biopsychologist and faculty member at San José State University, says: “When leaders model genuine and open communication, they signal that authenticity is welcome. Creating a culture where people feel supported, connected and safe to show up as themselves.” 

The People Space view is that this is where human-centred change becomes commercially relevant. Psychological safety is often discussed as a culture issue but in repeated transformation it becomes a sensing system, helping organisations find friction early, adapt faster and reduce the hidden costs of confusion.

McLean also connects employee experience with efficiency. Organisations where HR is high performing at providing a great employee experience are 1.8 times more likely to report high performance at cost optimisation.  Employee experience during change affects whether people can keep working with focus, confidence and enough energy to sustain performance.

Organisations have spent years improving the machinery of change. The next advantage will come from designing change around the human brain expected to carry it.
