Embracing change in business depends far less on leadership strategy than most organisations assume. The evidence consistently points to the middle manager layer as the place where change initiatives succeed or stall.

Investing in manager capability before, during and after change is not a developmental add-on. It is the mechanism through which the rest of the change investment delivers its return.

Every organisation going through change has a theory of how it will happen. Senior leadership sets the direction. A communications plan goes out. Managers are briefed. The assumption is that the organisation will follow.

McKinsey’s 2019 research on large-scale transformations consistently finds that roughly 70% do not achieve their intended outcomes. The most commonly cited causes are not technical failures. They are human ones: insufficient engagement, a failure to build genuine conviction at key layers of the organisation, and an underinvestment in building the capabilities that change actually requires.

The question worth sitting with, especially for those responsible for people development, is which layer of the organisation is bearing most of that weight, and whether the investment is reaching it.

Where Change Actually Stalls

Change does not typically fail at the top of an organisation. The strategic decision has been made, the rationale is understood, and senior leaders have had time to work through their own response before the initiative goes public.

It does not tend to fail at the front line either, where people are closer to the practical reality of the work and often quicker to adapt once they understand what is being asked of them.

It stalls in the middle. At the layer of managers who have received a brief and are now responsible for translating it into daily reality for their teams. They answer the questions the communications plan did not anticipate. They absorb the anxiety that change generates. They are expected to present a coherent and consistent face upward to leadership and downward to their teams, often simultaneously, often without having had the space to process their own response to the change first.

This is not a small task. And for most managers in the UK, it is one they are being asked to perform without adequate preparation.

The Scale of the Gap

The Chartered Management Institute’s Better Management Report, published in partnership with YouGov in October 2023, found that 82% of people who take on management responsibilities in the UK do so without any formal management or leadership training.

These are the people the report describes as accidental managers promoted for technical competence or organisational availability, not for their ability to lead people through difficulty.

The same research found that one in three workers and managers have left a job because of a negative working culture. Half of those who describe their manager as ineffective are planning to leave within the next year. The connection between undertrained managers and attrition is not a soft conclusion. It is a measurable business cost.

Change amplifies every existing gap in that picture. The manager, who was already unsure how to have a difficult conversation, now needs to have several. The manager who found it hard to maintain team confidence under stable conditions is now doing so amid uncertainty. The manager who had not yet built real trust with their team is being asked to request something significant from them.

What HR and L&D Are Typically Missing

Organisations investing in change tend to concentrate that investment at the strategic and communication layer. Senior leaders receive support. Narrative frameworks are developed. Project management infrastructure is put in place. These things matter. They are not sufficient.

What tends to be absent is investment in the manager layer, specific to what the change actually requires of them. Not as project implementers, but as people who must first process their own response to uncertainty before they can credibly help their teams do the same.

The World Economic Forum’s Future of Jobs Report 2025 identifies resilience, adaptability, and leadership as among the most critical capabilities for the period ahead. These are not skills that develop through a briefing or a town hall. They develop through sustained practice, structured reflection, and the kind of support that creates space for genuine development rather than performance under pressure.

The gap between what organisations ask of their managers during change and what they provide to develop those capabilities is where L&D investment is most consistently thin. This is not a failure of intent. It is a structural one: change programmes are frequently designed by people who are not close enough to the manager’s lived experience to see where the friction actually is.

The Investment Case

The business case for investing in manager capability during change is not difficult to make, once the real cost of the alternative is visible.

Attrition during and after change programmes is rarely attributed to the change itself in exit data. It appears as culture, management quality, or lack of development. But the CMI research makes the mechanism clear: undertrained managers in high-pressure conditions produce exactly the working environment that drives people out. 

The cost of replacing those people, in recruitment, onboarding and the time it takes for someone to become genuinely productive, is significant in any organisation, and considerably higher than the cost of developing the manager who might have retained them.

Beyond retention, there is the cost of the change itself, underdelivering. A technology rollout that has not accounted for the manager's own relationship with the change will encounter resistance that no communication plan can resolve. 

A restructure that has not given managers the space to process their own responses before leading their teams through them will produce defensive, compliance-driven behaviours that slow momentum and erode trust.

The skills that GfG’s research with emerging leaders consistently identifies as most needed are not technical. They have the capacity to build their own and their team's resilience, to develop the mindset that enables them to embrace flexibility and change, and to improve the quality of their communication and coaching with their teams. These are the capabilities that determine whether change lands. And they are the ones that receive the least investment.

The Question For People Professionals

If you are designing or commissioning a change programme, or reviewing where your L&D investment is currently going, it is worth asking how much of it specifically reaches the middle manager layer. Not as recipients of a message, but as people who need their own development investment to be able to do what is being asked of them.

The change that is hardest to land is not the one that was poorly designed at the top. It is the one that was well designed, clearly communicated, and then handed to managers who had no support for what came next.

The middle manager is not a conduit for change. They are the critical variable in whether it takes hold.
