Episode Summary

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.
