HumanOS Heroes: Sustainable High Performing Cultures In Action

In this episode of HumanOS Heroes, Bianca Errigo is joined by Andrew Dewar, Head of People at Oxygen Conservation — an organisation redefining what it means to align business with environmental and human purpose.

With a background spanning psychology, performance, and leadership across music, sport, and social impact, Andrew brings a deeply human perspective to what drives sustainable performance in today’s workplace. His career journey — from publishing academic papers on wellbeing and coaching high-performing teams, to now leading people strategy in a company tackling the climate crisis — offers a fascinating lens into how meaning, purpose, and performance intersect.

Together, Bianca and Andrew explore:

• What sustainable high performance really looks like for leaders and teams
• How Oxygen Conservation is creating an environment where purpose drives performance
• The reality of burnout and overwork, and practical ways to help people recover without losing momentum
• The “achievement trap” — how the constant pursuit of excellence can unintentionally undermine fulfilment and wellbeing
• The power of microbehaviours in shaping organisational values and building authentic, purpose-led cultures

This conversation offers a powerful reframe for managers and leaders: that lasting success isn’t about pushing harder, but about creating the conditions where both people and performance can thrive — sustainably.
