When Pennine Logistics — a Leeds-based haulage and warehousing firm employing 640 staff across four depots — announced a shift to a single regional operating model, productivity fell for three months before recovering. The board had approved the strategy but no one had managed the human transition.
Change management is the disciplined application of structure, communication, and support to move an organisation from a current state to a target state while protecting performance and retaining critical skills. Two frameworks dominate UK practice: Kotter's 8-step model and the ADKAR model.
Kotter's model is organisation-facing. It runs from creating urgency, building a guiding coalition, and forming a vision, through enabling action and generating short-term wins, to consolidating gains and anchoring new approaches in the culture. ADKAR is individual-facing, tracking each person through Awareness, Desire, Knowledge, Ability, and Reinforcement.
ADKAR model
A people-centred change framework that identifies five conditions an individual must satisfy for change to hold: Awareness of why change is needed, Desire to participate, Knowledge of how to change, Ability to apply new behaviours, and Reinforcement to sustain them. Each stage maps to a distinct HR intervention — communication, engagement, training, coaching, and recognition.
In a UK context the sequencing of change is constrained by law. Where transformation involves potential redundancies or a transfer, the employer's consultation duties under s.188 TULRCA 1992 or TUPE 2006 cannot be retro-fitted after the plan is announced. Genuine consultation must precede final decisions, so the change roadmap and the legal timetable must be designed together.
Guiding coalition (Kotter step 2)
A cross-functional sponsor group with the authority, credibility, and operational knowledge to lead a change programme. In UK organisations the coalition typically pairs an executive sponsor with line managers and, where a union is recognised, an early route to employee representatives — so that the change story and the consultation duty stay aligned.
The HR director builds a guiding coalition of the operations director, four depot managers, and two elected employee representatives. Awareness is created through depot briefings before any structure is published. Desire is built by involving managers in designing the new regional rotas. Knowledge and Ability are delivered through three months of on-the-job training before go-live, and Reinforcement comes from depot 'change champions' who support colleagues through the first 90 days. Peak absence during transition is held at 5.6%, against a sector benchmark of roughly 8% for comparable restructures.
| Kotter step | Primary HR activity | UK legal checkpoint |
|---|---|---|
| Create urgency / form vision | Board briefing, change narrative, FAQ | Confirm whether redundancies or TUPE are in scope |
| Build coalition / enable action | Manager workshops, rota co-design | Begin s.188 / TUPE consultation before decisions |
| Short-term wins | Pilot depot, publish early results | Document consultation responses considered |
| Anchor change | Embed new roles, recognition scheme | Issue revised written statements (s.1 ERA 1996) |
⚠️Announcing the new structure before consultation begins
→ Where redundancies or a transfer are in scope, a settled decision before consultation breaches s.188 TULRCA 1992 or TUPE 2006 and risks protective awards. Consult on proposals, not on a fait accompli.
⚠️Treating line managers as messengers, not change agents
→ Middle managers are the point of leverage. Equip and convince them before go-live — change announced over their heads collapses in delivery.
⚠️Declaring success with no adoption metrics
→ Without baselined measures — engagement, error rates, attrition of key staff — 'transformation complete' is a claim, not a fact. Define KPIs before launch.
