In my last article, The Myth of the Rational Merger, I explained that mergers and acquisitions rarely fail on paper. They more often derail in the complexity of reality, where organisations must make decisions together, cooperate in new ways, and sustain a new structure while the familiar reference points have yet to be rebuilt.
In this article, I give voice to what is experienced on the ground every day.
On the ground, the signals appear early. And they are remarkably consistent.
At first, they are not spectacular crises. They are diffuse frictions: meetings that drag on, decisions that slow down, working methods that clash, rules that change without explanation. On paper, the integration seems coherent. But in the daily lives of teams, something is already beginning to seize up.
This is often where the crux of the matter lies. Because the ground speaks long before the crisis does.
The Consequences of Ignoring the Signals
When these signals are neither heard nor addressed, they produce very tangible effects.
First, commitment erodes. Not always noisily. Resistance often becomes silent. Employees stay, perform, and appear to adapt… but internally, the connection has weakened. Engagement does not vanish overnight; it recedes gradually.
Next, key skills become fragile. The individuals who held the operational knowledge, the professional memory, and the practical shortcuts begin to doubt—and sometimes leave. And when they depart, they take more than just a position with them: they take expertise, an understanding of the system, and a continuity that was once taken for granted.
The climate also shifts. Trust declines. Tensions rise. What was once cooperation becomes more political, more cautious, more defensive. Roles blur, priorities shift constantly, and teams feel they must absorb contradictory demands with fewer resources.
Finally, it is often managers who pay the highest price for this disorganisation. They become the shock absorbers of the system: expected to reassure without visibility, arbitrate without a stable framework, explain ever-changing decisions, and uphold the company’s credibility when they themselves no longer have all the reference points. Over time, hesitation sets in, fatigue grows, and the risk of burnout increases.
What is often mistaken for individual fragility is usually a collective symptom.
A classic mistake in post-merger phases is to psychologise what is actually organisational.
We talk of a lack of engagement, resistance to change, vulnerable managers, and demotivated teams. But what the ground most often reveals is something else: a system that has not adequately anticipated the human, cultural, and relational effects of the transformation.
When decision-making rules become unclear, when evaluation criteria change without explanation, when spaces for dialogue disappear, people do not “resist” for no reason. They react to an environment that has become more uncertain, more opaque, and sometimes more inconsistent.
In other words, the unease is not primarily a problem of individuals. It is a structural signal.
Listening to the Ground: A Strategic Responsibility
The ground always speaks. The only real question is when the organisation chooses to listen.
Listening early is not about creating a symbolic space for expression. It is about equipping yourself to detect what is deteriorating before it becomes costlier: loss of commitment, talent departures, managerial fatigue, internal tensions, and declining quality of execution.
In a merger or acquisition, human factors are not a peripheral issue to be addressed “once everything else is secure.” They are at the heart of the organisation’s real ability to integrate, endure, and perform over time.
This is why listening to the ground is not an optional social gesture. It is an opportunity to hear what the organisation is trying to say… before the crisis speaks for it.
