Kickstart your growth with The TCM Academy

The TCM Academy delivers a wider range of training courses and events on a virtual, face to face and blended basis. Below are just a few of our upcoming courses and events.

A Consultancy You Can Trust!

In 2023, we won the prestigious Personnel Today HR Impact Award in partnership with Burberry. Working with the TCM Group, Burberry conducted an audit of its team climate, systems and policies, identifying a number of key areas for improvement: upskilling HR and leaders in conflict management; reviewing policies and steps to resolution; a need for a confidential whistleblowing helpline only used for the most serious issues; and alignment of investigations processes so they were globally consistent. Feedback suggests that colleagues now feel more empowered to speak up, and there has been an increase in issues being resolved without the need for recourse to a formal procedure.

Purpose and values. Aligned.

Organisations which fully integrate their purpose and their values will be the successful organisations of the future. Combined, your values and purpose reflect the kind of organisation you are – they define your employee experience (EX) and your customer experience (CX). When corporate strategies and management behaviours are aligned to your purpose and values, this becomes the defining feature of your organisation.

We help organisations to define and embed their purpose and their values and to align these to their strategy, their behaviours and their leadership and management competencies.

Tomorrow's leaders. Today.

Your leaders have a significant influence on company culture and your managers should create the climate for success. By equipping your leaders and managers with the skills they need during these volatile uncertain, complex and ambiguous (VUCA) times, your organisation will help your most valuable asset to shine – your people.

Through a range of leadership development, training and consultancy packages, we equip leaders and managers with the confidence, competence, characteristics and capabilities to lead their teams through the good times, and the bad.

Putting the human into HR.

The traditional human resources (HR) function is evolving. The emergence of the People and Culture function presents enormous opportunities for HR to deliver fair, just, inclusive, sustainable and high performing systems, processes and cultures. TCM is working with an increasing number of HR teams to help them as they evolve into a people and culture function. From the development of a people and culture strategy to the design and deployment of modern employee handbooks, values and behavioural recruitment processes, and transformational performance management systems. If you want to put the human back into HR, we are here to help.

Evidence based. Practically delivered.

The use of data and evidence to inform and evaluate organisational change programmes is central to their short- and long-term success. We build a business case for cultural transformation using normative, qualitative and quantitative approaches such as existing HR and management data, and the engagement of key stakeholders such as people and culture professionals, leaders, managers, employees and unions.
