Why is it that someone brilliant in their role can suddenly struggle the moment they step into leadership? It’s one of the most common – and painful – challenges in business. As we said in episode one, people can only be as good as the person above them, and today we dig into what that really means.

In this episode, Tommy explores a question every founder, manager and HR leader eventually faces:
Can anyone become a great leader… and if not, what do you do?

Drawing on research from Gallup, SHL, Daniel Goleman and Aon Hewitt, plus decades of real-world people-leadership experience, this conversation unpacks why leadership isn’t a title, a promotion or a straight career ladder. It’s a responsibility — and not everyone is wired the same way.

You’ll also learn how to assess leadership readiness, how to spot genuine potential, what to do when someone isn’t suited to managing people, and how to create a culture where both leaders and technical experts can thrive.

Promotions often reward technical brilliance, not people capability. It’s a trap most businesses fall into — and it creates confusion, disengagement and frustration on both sides.

2. The three respected leadership frameworks

Tommy breaks down SHL, Daniel Goleman and Gallup to show the consistent attributes that make leadership effective:
Vision, communication, influence and disciplined follow-through.

3. The Leadership Mirror: Seven questions to diagnose leadership behaviour

A powerful self-assessment tool for founders and managers to evaluate whether someone is genuinely suited to people leadership.

4. The Leadership Potential Checklist

A second lens to spot whether someone has the raw traits needed for leadership — even if they’re not demonstrating them yet.

5. What to do when someone struggles in a leadership role

From timing conversations to creating psychological safety, Tommy shares a human-centred approach for exploring role clarity without shame or fear.

6. Why technical leadership can be a powerful alternative pathway

Not everyone should lead people — and that’s not only okay, it can unlock even greater value inside a business.

7. The uncomfortable mirror every leader must hold up

Culture, clarity and consistency start at the top. Your example shapes everyone below you.

 Key Takeaways
Promoting top performers into leadership is common — but the skills rarely translate.
Around 70% of team engagement is shaped directly by the manager.
Leadership suitability can be assessed with simple A/B questions covering communication, vision, trust, awareness and consistency.
Some people have strong leadership potential but lack capability or confidence — training and environment matter.
Others are better suited to technical leadership, where impact comes from mastery, not managing people.
Poor leadership affects engagement, profit, retention and performance — the data is overwhelmingly clear.
Hard conversations about role fit can unlock career clarity rather than failure.
Leadership development always begins with you, not the people below you.



Research Mentioned
Gallup: 70% of employee engagement is influenced by the direct manager.
Aon Hewitt: High-engagement companies show 50% higher shareholder return, 33% lower turnover, and higher operating profit.
