Our Team

Meet the award-winning Resolution Framework™ team.


David Liddle – CEO of The TCM Group and Creator of the Resolution Framework™


Throughout his career in mediation and restorative justice, David has worked tirelessly to promote dialogue as an effective approach to conflict and complaints resolution. However, organisations  continued application of retributive and adversarial  grievance and disciplinary procedures acts as a direct barrier to dialogue. Increasingly frustrated with the negative impact of these procedures, David went on a mission to rid the world of the damaging and destructive grievance and disciplinary procedures. David launched his now award winning and highly acclaimed Resolution Framework™ in 2013. The Framework is now embedded in numerous organisations across the UK, and beyond.
