John Hayes is Emeritus Professor of Change Management at Leeds University Business School and is a regular contributor to executive programmes at several European business schools. He also helps to facilitate change in complex organizational settings and has worked for a wide range of private, public and third sector organizations, including British Gas, Nestle, National Australia Group, NHS and NACRO.

John’s early research was in the field of vocational development. This led to an interest in how change affects individuals and, later, to the management of change in organisations. The sixth edition of his best-selling book The Theory and Practice of Change Management was published in 2021.

One of John’s research interests is how managers go about learning and mastering the tasks which confront them. This led to a rolling programme of research with Professor Chris Allinson that focused on cognitive styles and, in 1996, the publication of the Cognitive Style Index. Work on reciprocal compatibility in the workplace led to John and Chris working with Professor Steve Armstrong on how cognitive styles affect supervisor-subordinate relationships.
