“The Great Leadership Disconnect offers a bold and inspiring call to reimagine how business and HR lead together. Serkan’s voice is uniquely compelling – rooted in real commercial experience, strengthened by deep people insight, and enriched by a global lens. Few leaders can speak to this divide with such clarity and conviction. This book not only diagnoses the disconnect; it shows how organisations can rise above it and unlock their full human potential.”

“Although HR and business/commercial teams must work together to be successful, it’s rare to find someone like Serkan who thrived so effortlessly in both environments. I was lucky enough to experience Serkan move from a commercial role to a HR business partner and in doing so bring unique insights and the kind of constructive challenge only someone with a broad mindset matched with a deep gritty understanding of business mechanics can master. I can’t think of anyone better to make the case for deeper integration and understanding between those two worlds.”

“A Unique Voice Bridging HR and Business Strategy: I’ve had the privilege of knowing Serkan throughout his remarkable career journey, watching him master both the business and human resources sides of organizations. This unique dual perspective makes his new book particularly valuable – it’s not theoretical advice from someone who’s only observed from one angle, but practical wisdom from someone who’s actually lived in both worlds. This fantastic book distills years of hands-on experience into actionable insights. I highly recommend this book to leaders who understand that the future belongs to organizations where human resources and business strategy work as one.”

This book cuts through the theory to show exactly how to align people growth and revenue growth. A timely and vital contribution to the field of modern leadership.”

“With sharp insights and unflinching honesty, The Great Leadership Disconnect cuts through outdated assumptions about HR and exposes the systemic flaws behind broken people strategies. It offers a grounded, compelling blueprint for leaders who want to design cultures, talent practices, and organizations that truly deliver business impact.”
Stefano Pichiecchio, Global Talent Leader, Microsoft
“This book captures something many leaders feel but rarely articulate: the disconnect between people strategy and commercial reality isn’t a communication issue, it’s a leadership issue. Serkan brings a global, deeply practical perspective that challenges both HR and business leaders to rethink how they show up, make decisions, and share accountability. The stories are real, the insights are grounded, and the guidance is immediately usable. A powerful contribution for any organisation serious about unlocking the full potential of its people and its leadership.”
Steve O’Reilly, Vice-President, People & Capability, UK & Ireland, Mastercard

His transition from an HR role into a business leadership role has clearly shaped the way he leads and thinks. This experience gives him a unique, credible viewpoint on how HR and business must work in true partnership to drive results in an ever-changing world of work. He communicates these insights with clarity, authenticity, and strong storytelling, making him a compelling and insightful writer on this topic.”
