Change Leadership & Consulting

Changerous.

You can be the most changerous person in the room.

For the leader handed a change with no playbook. For the HR professional absorbing fallout from decisions made above them. For the organisation that needs change to actually work.

The Story

Twenty years inside one of Canada's most complex organisations. Now building what I learned into something others can use.

My name is David Deeks. For two decades, I led operations and change management at Canada Post Corporation — a federal Crown corporation, one of the largest employers in the country, and one of the most heavily unionised operational environments in North America.

I directed 24/7 operations with annual budgets exceeding $90 million. I managed the safety, performance, and development of more than 1,400 people across Canada's largest letter mail processing facility. And when the organisation embarked on its most ambitious digital transformation in modern history, I was asked to lead the change.

That meant standing in front of 55,000 employees — frontline postal workers, team leaders, union representatives, and executives — and asking them to trust a new way of working. Not once. Hundreds of times. Across multiple releases, in rooms that were sometimes welcoming and sometimes hostile, with bargaining agents watching every step.

I digitised and modernised the systems people use in the most sensitive moments of their working lives: discipline, grievances, human rights, disability accommodation, health and safety reporting, and seniority-based job bidding. These aren't workflow changes. They're trust changes. And they required a fundamentally different kind of leadership.

Changerous exists because what I learned in those rooms — about trust, about presence, about meeting people where they are — shouldn't stay inside one organisation. It's too useful. And too many people are navigating change alone.

Historic First

Automated Job Bidding System

Implemented the first-ever fully automated job bidding system for 40,000 unionised CUPW members nationwide. Required three months of cross-country travel to lead deployments and manage a distributed team operating remotely in parallel. This represented a fundamental shift in how union seniority rights were exercised — one of the most closely guarded provisions in any collective agreement. System adoption remains strong with consistent monthly usage across all impacted audiences.

Culture Shift

Health & Safety Digital Transformation

Migrated all manual incident management, LJHSC processes, and hazard reporting to a unified digital platform. For the first time in the organisation's history, every employee could report a workplace hazard online — a fundamental shift in safety culture for a frontline workforce facing real physical risks daily. Deployed in parallel with a leading indicators portal including a job suitability assessment tool for employees not at full duties.

National Rollout

Grievance & Consequence Management

Digitised and modernised the end-to-end grievance management system — from filing through resolution — and the consequence management system governing 24-hour notice interviews and progressive discipline. These are the most legally sensitive and emotionally charged processes in a unionised workplace. Moved entirely from paper to a single integrated digital platform used by team leaders and HR professionals across the country.

135+ sessions delivered for a single release
Rapid Execution

Performance Management System (SuccessFactors)

Led the change management deployment of a new national performance management system impacting 8,000 employees in leadership roles. Initiated mid-2025 with a go-live of January 1, 2026 — a five-month turnaround. Delivered by a team of two, working closely with a three-person project team, including 40+ sessions guiding leaders through the full ADKAR change curve.

The Approach
01
The framework is the floor, not the ceiling.
ADKAR, Prosci, Kotter — I'm certified and fluent in the models. But the practitioner who can read a room, adapt in real time, and know when to start again is worth ten people who can only work the formula. Fluidity and flexibility matter more than methodology.
02
Put your face on it.
If you won't stand in front of the people your change affects, you don't believe in it enough. I led over 135 sessions for a single release — awareness, orientation, training, post go-live — always as the lead, always on camera. That's not heroism. That's the minimum.
03
Resistance isn't a problem. It's information.
People resist when they feel unheard, unprepared, or uncertain. That's not defiance — that's human. The real work isn't pushing harder or explaining louder. It's meeting people where they are. Not where we are. Not where the plan says they should be.
04
Credibility is your only currency.
Every promise you make in a change program is a withdrawal from a trust account. If you overdraw — if the go-live fails, if the tool doesn't work, if the experience doesn't match the message — you don't just lose that moment. You lose every conversation that follows.
05
Check your ego at the door.
I learned this in rooms with some of Canada's most experienced union representatives. Management ego is lethal in adversarial environments. Meet people where they are. Listen more than you speak. And sometimes, start again — because doubling down on what isn't working never ends well.
06
Focus on the fencesitters.
The early adopters are already in. The loud detractors may never be. It's the people in the middle — watching, evaluating, waiting to see if this change is safe, logical, worth it — who determine whether your change takes root. Shift them, and you shift everything.

Work With Me
Change management built for organisations that need it to actually work — without the enterprise price tag.

Changerous brings twenty years of national-scale change leadership to organisations that don't have a dedicated change management team — but whose people deserve the same quality of thinking.

Whether you're navigating a technology rollout, a restructure, a process overhaul, or a culture shift, the approach is the same: understand the humans first, build the strategy second, and stay in the room until it sticks.

Change Strategy & Planning
End-to-end change management strategy built on ADKAR methodology and twenty years of real-world adaptation. From stakeholder mapping to communication plans to readiness assessments — grounded in what actually works.
Leadership Coaching
One-on-one and team coaching for leaders navigating change — including the hard conversations about resistance, credibility, ego, and what to do when the plan stops working.
Training & Facilitation
Awareness sessions, orientation, skills training, and post go-live support. Designed for engagement, not attendance. Built by someone who has personally delivered hundreds of these sessions.
Speaking & Workshops
Keynotes, panel participation, and interactive workshops on change leadership, resistance, and building trust in complex environments. Practical, honest, and grounded in lived experience.
