The Human Impact

The hidden behavioural impact of executive departures.

When a Chief Executive leaves an organisation, attention almost immediately turns to who will replace them.

The recruitment process begins. Interim arrangements are considered. Governance discussions take place.

But there's another question we rarely stop to ask.

What happens to the organisation they leave behind?

Across New Zealand's local government sector, Chief Executive departures are bringing this question into sharp focus right now, with movement on a weekly basis. 

Some departures are carefully planned, allowing time for a structured handover. Others happen unexpectedly, leaving an organisation navigating an immediate leadership gap.

Either way, the impact goes well beyond an empty office.

When leadership changes, people experience loss

A Chief Executive brings more than strategic direction and decision-making authority.

They bring mana, relationships, clarity, confidence and a sense of hope that the organisation can achieve what it has set out to do.

Over time, particularly when a CEO has been in place for several years, their leadership becomes woven into the everyday fabric of the organisation.

People learn how decisions are made, how to communicate, what matters, what is expected and how to navigate challenges.

Then that familiar environment changes.

For some, there is sadness. For others, relief, uncertainty or even excitement. Sometimes all these emotions exist within the same organisation.

But regardless of how people feel about the departure, they must begin adjusting to the loss of something familiar.

It's a form of organisational detachment.

And it can have a significant impact on organisational behaviours.

The organisational detachment cycle

In our work with leadership teams navigating significant change, we regularly observe how uncertainty influences behaviour.

A CEO departure can trigger a progression that I describe as:

Loss → Detachment → Disruption → Derailment

Loss: A familiar leadership presence disappears. Relationships, expectations and established ways of working begin to shift.

Detachment: People start questioning the future. Some hold back on decisions, disengage from priorities or become reluctant to commit to initiatives that may change under new leadership.

Disruption: Communication patterns shift. Decision-making can slow. Informal conversations increase, assumptions develop and teams may retreat into their own areas of responsibility.

Derailment: If uncertainty continues without deliberate intervention, organisational confidence, momentum and performance can begin to deteriorate.

This isn't an inevitable sequence, nor does every organisation experience every stage.

But it illustrates something important.

When uncertainty isn't understood, it can begin to drive significant signals of behaviour change.

And behaviour ultimately influences organisational performance.

The questions people don't always ask out loud

When a CEO leaves, employees may begin asking themselves:

• Will the direction we've been working towards continue?

• Will the new CEO value what we've achieved?

• Will I have to adapt to an entirely different leadership style?

• What will happen to my role or my team?

• Who makes the decisions now?

• Should I keep pushing forward or wait?

These aren't necessarily signs of resistance.

They are often natural responses to uncertainty.

Yet if leaders don't recognise what's happening beneath the surface, those questions can quietly influence how people communicate, collaborate and make decisions.

This is why I often say:

Behaviour is a great  form of data analysis. 

What people do, what they stop doing, what they avoid and how they respond to uncertainty can tell us a great deal about the health of an organisation.

Recognising the transition before it becomes a problem

The solution isn't to remove every uncertainty. That's impossible.

It's to recognise the behavioural impact of the transition and create enough clarity, connection and confidence for people to keep moving forward.

That means communicating honestly, acknowledging the contribution of the departing leader, explaining what remains unchanged and ensuring people know where leadership and decision-making responsibilities sit.

It also means paying close and consistent  attention to the behaviours emerging across the organisation.

Are people withdrawing? Are decisions being delayed? Are teams becoming more protective of their own priorities? Is confidence beginning to slip?

These are signals worth understanding, not simply problems to manage.

A Chief Executive departure may be unavoidable.

Organisational derailment doesn't have to be.

And perhaps the most important question is not simply who will lead the organisation next.

It's how we protect the people, confidence and momentum of the organisation while that leadership changes.
