17 Jan Leading as One: What Senior Teams Can Learn from Greene King’s CEO

Senior leadership today is rarely about managing steady state. It’s about navigating constant movement – shifting markets, changing expectations, organisational complexity and sustained pressure. In that context, what really enables senior teams to lead effectively, stay aligned and perform over the long term?

In a recent IGNITE webinar, Fieri Chair Adrian Moorhouse sat down with Nick Mackenzie, CEO of Greene King, to explore these questions in depth. Drawing on his experience leading a large, multi-site organisation through years of change, Nick shared candid reflections on leadership, resilience and what it takes to build high-performing senior teams.

What emerged was not a set of abstract theories, but a clear picture of leadership in practice – grounded, disciplined and deeply human. Five themes in particular stood out.

1. The Executive Team must be the primary team

One of the strongest ideas in the conversation was Nick’s belief that the executive team must operate as the primary team – not the individual function teams.

In large organisations, it’s easy for senior leaders to default to representing their function or protecting their patch. While understandable, this mindset quickly creates friction, slows decision-making and weakens alignment. Nick described the shift required when leaders move from a functional to an enterprise mindset – making decisions for the good of the whole organisation, even when that creates local discomfort.

When the executive team genuinely leads as one, something changes. Conversations become more constructive. Trade-offs are surfaced and owned collectively. Decisions are clearer because they are anchored in enterprise priorities rather than functional optimisation.

For senior teams navigating complexity, this discipline is foundational. Alignment at the top doesn’t happen by chance – it is a deliberate way of operating.

2. Belief in people is a powerful performance lever

Nick reflected on the impact of leaders who believed in him early in his career – often before he fully believed in himself. Those moments of trust and opportunity shaped his trajectory and informed how he now leads others.

What came through strongly is that belief is not a soft concept; in practice, it accelerates capability. When leaders back people early, create space for stretch and support them through uncertainty, individuals step up more quickly and with greater confidence.

In large organisations, this matters at scale. Senior teams set the tone for how talent is spotted, developed and trusted. A culture where belief is visible – where leaders are willing to take considered risks on people – builds depth, resilience and momentum.

For HR and business leaders, this is a reminder that talent strategy is inseparable from leadership behaviour at the top.

3. Resilience Is built collectively, not individually

Leadership resilience is often framed as an individual trait: stamina, toughness, the ability to keep going. Nick’s perspective was notably different.

Despite leading through multiple periods of disruption, he spoke about resilience as something created with others – through trusted relationships, shared responsibility and collective support. He emphasised the importance of having people around you who challenge, steady and strengthen you, particularly when pressure is high.

In senior teams, resilience is not about heroic endurance; it’s about the quality of the system around the leader. Teams that trust each other, challenge openly and share the load are far better equipped to absorb volatility without transmitting stress through the organisation.

For organisations facing ongoing change, building this kind of collective resilience at senior level is a strategic priority, not a wellbeing initiative.

4. Trust enables challenge – and challenge enables performance

Another recurring theme was the relationship between trust and challenge. Nick spoke openly about how the absence of trust makes senior team dynamics fragile, while strong trust enables more honest, productive debate.

High-performing senior teams do not avoid disagreement. They lean into it – constructively. Trust creates the conditions where challenge is not personal, defensive or political, but focused on improving the quality of decisions.

This is particularly critical in complex environments, where there are rarely clear or easy answers. Senior teams that can debate rigorously and then commit collectively are far better positioned to move at pace without fracturing.

For HR and leadership professionals, this highlights the importance of focusing not just on what senior teams decide, but how they work together when the stakes are high.

5. Performance must be balanced to be sustainable

When asked how he thinks about performance, Nick did not default to a single metric. Instead, he described performance as multi-dimensional – encompassing financial results, customers, people, operations and ownership.

This balanced view reflects the reality facing many senior leaders today. Narrow definitions of performance may deliver short-term results, but they rarely build organisations that endure. Sustainable performance requires leaders to hold multiple perspectives at once and make decisions that strengthen the system as a whole.

For senior teams, this demands maturity and discipline. It requires resisting false trade-offs and recognising that people, culture and long-term capability are not distractions from performance – they are central to it.

What senior teams can take away

This conversation offered a rare window into how a CEO of a large organisation thinks about leadership – not as a personal philosophy, but as a daily practice shaped by responsibility, complexity and consequence.

For senior HR and business leaders, several takeaways stand out:

• Alignment at the top is a discipline, not an aspiration.
• Belief in people’s potential accelerates capability and builds organisational strength.
• Resilience is created through relationships, not individual toughness.
• Trust and challenge must coexist for senior teams to perform well.
• Sustainable performance depends on balance, not single-minded focus.

Taken together, these insights reinforce what we see repeatedly in high-performing organisations: senior teams who lead with clarity, humility and collective intent.
