Conflict may occur in a group of people working together, even if they all share a common goal, measurable targets and a clear vision. Many leaders try to avoid conflict at all costs and when it arises tend to manage disagreements inappropriately. Dealing with conflict constructively can lead to increased productivity, new ideas being generated and personal development for all team members. 


David Liddle

For the past 20 years David has been successfully promoting the principles and practices of mediation and non-violence across numerous walks of life including neighbourhoods, schools, prisons, workplaces and boardrooms.

David has been instrumental in transforming attitudes to conflict management and he has played a major role in cementing mediation as a credible and mainstream activity for some of the most well-known and valued brands. He is collaborative by nature having built partnerships with business leaders, public servants and politicians in the UK and globally.

His ethos, his expertise, his experience and his vision deliver tangible and sustainable benefits at an economic and a human level for his clients. His highly regarded and sought after interventions deliver enhanced performance and efficiency within the boardroom; improved wellbeing and resilience for leaders and employees; greater employee engagement; and a significant reduction in the cost of conflict and litigation.

As the Founder and CEO of The TCM Group, one of Europe’s leading private sector mediation companies, David works with some of the world’s top mediators and trainers of mediators. At TCM, David and his team strive to develop systems and services which promote collaborative justice – a modern and highly effective form of justice. In doing so, he actively challenges traditional systems of justice which he believes are no longer fit for purpose being inherently adversarial, confrontational and complex.

David has created 2 models which are helping organisations to manage conflict and change. The FAIR Mediation Model™ and The Insight Change Model™

In 2007, resulting from his concerns about a lack of a quality framework for professional mediators, David set up the Professional Mediators' Association (PMA). The PMA is dedicated to promoting excellence in mediation.
