The Leadership Mistake That Makes Transformation Cost More | with Mark Green

Hierarchy kills transformation when leaders forget the people doing the work. If your company is pushing through constant change, this conversation is for you. Tatiana Koval, host of Happy at Work, sits down with Mark Green, founder and CEO of Change Rebellion, to unpack why so many transformations fail before they even begin - and what leaders must ask before launching the next big initiative. Tatiana and Mark explore one of the biggest tensions in modern transformation: should organizations plan everything in detail, or start fast and adapt? Mark’s answer is refreshingly practical - it depends on the goal, the context, and whether the approach actually fits the people involved. Essential listening for leaders, HR professionals, change managers, and anyone trying to guide a team through uncertainty without losing trust, energy, or momentum. Mark Green is the founder and CEO of Change Rebellion, a change management service and consultancy. With nearly 30 years in change management, he is known for a practical, people-first approach that challenges traditional thinking about transformation.
