Organisational change in the UK has specific constraints that generic change management frameworks miss: TUPE obligations, collective consultation requirements, union engagement rules, and the practical reality that most UK employees hear about restructures from the BBC before they hear from their own leadership. This playbook covers what to do and in what order.
Phase 1: Before the Announcement (Weeks -4 to -1)
Stakeholder Mapping
Map every stakeholder group against two axes: level of impact and level of influence. This is not optional — it determines your entire sequencing.
- High impact, high influence: Senior leadership, board members, union representatives, works council. These people get briefed first, with enough lead time to ask questions before the wider announcement.
- High impact, low influence: Frontline employees directly affected by the change. They hear second, but only minutes after the first group — not days.
- Low impact, high influence: Industry analysts, key clients, regulators. Brief them on day one or day two depending on disclosure requirements.
- Low impact, low influence: Wider organisation, suppliers. They get the all-staff communication.
Legal and HR Alignment
Before you write a single word of messaging, sit down with employment law counsel and HR. In the UK, this is non-negotiable for changes involving:
- 20+ redundancies at one establishment (triggers collective consultation under s.188 TULRCA 1992 — minimum 30 days)
- 100+ redundancies (minimum 45 days consultation, plus notification to the Insolvency Service via HR1 form)
- TUPE transfers (information and consultation obligations with recognised unions or elected employee reps)
Your comms timeline is constrained by these legal timelines. Build the comms plan around them, not the other way around.
Pre-Brief Line Managers
Managers are the single most important channel during change. Gallagher's research consistently shows that 70%+ of employees trust their direct manager more than any other source during uncertainty. Brief managers 24-48 hours before the announcement with:
- The key messages (max 3)
- A Q&A document covering the 15-20 most likely questions
- Clear guidance on what they can and cannot say
- A named contact for escalating questions they cannot answer
Common Mistake: The Information Vacuum
A mid-cap UK financial services firm planned a restructure but delayed internal comms by two weeks while legal reviewed messaging. During that gap, a journalist at the FT picked up rumours from a departing contractor. The story ran before employees were told. Trust scores collapsed, three senior hires rescinded their offers, and the consultation process became adversarial. The fix is simple: agree a holding statement for internal use on day one of planning, even if it says very little.
Phase 2: The Announcement (Day 0)
Sequencing (This Order Matters)
1. T-60 minutes: Brief the board/exec committee (if not already involved in the decision) 2. T-30 minutes: Brief line managers via a live call. Give them the Q&A, the timeline, and permission to say "I don't know yet" to questions not covered 3. T-0: CEO all-staff communication. Email plus live town hall (or recorded video if time zones make live impossible) 4. T+30 minutes: External announcement if required (RNS for listed companies, press release, regulator notification) 5. T+2 hours: Client and supplier notification from relationship owners
Message Structure
The all-staff message must answer five questions in this order:
1. What is changing? (One paragraph, factual, no spin) 2. Why? (Business rationale in plain language — "our costs are 15% above sector average" is better than "to ensure our long-term competitiveness") 3. Who is affected? (Be as specific as you can. "Teams in our Birmingham and Leeds offices" is better than "some roles across the organisation") 4. What happens next? (Dates, consultation process, who to talk to) 5. What is NOT changing? (This is often forgotten but reduces anxiety significantly)
Phase 3: The Consultation Period (Weeks 1-6+)
This is where most change comms programmes fail. The announcement gets attention; the follow-through gets neglected.
Weekly Update Rhythm
- Monday: Manager briefing call (15 minutes, live, with Q&A log shared afterwards)
- Wednesday: Short written update to all affected employees. Even if the update is "no new decisions this week" — silence during consultation is interpreted as secrecy
- Friday: Updated Q&A document published to the intranet, with new questions added from the week
Two-Way Channels
- Dedicated email inbox monitored daily (e.g., [email protected])
- Anonymous question submission via Microsoft Forms or a similar tool
- Drop-in sessions with HR — physical, not just virtual, if you have office-based staff
- Union/employee rep meetings at the cadence agreed in the consultation framework
Tracking Understanding
Open rates and click rates tell you nothing about whether people understood the message. Use these instead:
- Pulse survey question: "I understand how this change affects my role" (agree/disagree). Run every two weeks during consultation. Target: 65%+ agreement by week 4.
- Manager feedback forms: After each weekly briefing, managers submit a 3-question form: "What was the most common question?" / "What are people most worried about?" / "Is there anything I could not answer?"
- Consultation response analysis: Track the themes in formal consultation responses. If 60% of responses raise the same concern, you have a messaging gap.
Phase 4: Post-Change (Months 1-3)
Do Not Disappear
The most damaging thing leadership can do after a restructure is go quiet. The narrative vacuum gets filled with rumour and resentment.
- CEO should do a "30 days in" update addressing what has gone well and what has been harder than expected
- Managers should have a structured 1:1 conversation with every retained employee within the first month
- Track voluntary attrition in the 90 days post-change. If it spikes above normal levels, your change comms failed to retain trust — regardless of what the engagement survey says
Lessons Learned
Run a short retrospective with the comms team, HR, and 3-4 managers. Document what worked, what did not, and what you would change. Store it somewhere findable — you will need it for the next restructure, and there will be one.
