The Cost of Silence Due to Disengagement

A business can survive a bad quarter. It can recover from a failed campaign, a delayed project or even a difficult market cycle. What is harder to recover from is an organisation where people no longer know what is happening, why it matters or what is expected of them.

And yet, internal communication is still too often treated as a support function: the email that needs to go out, the newsletter that needs to be published, the CEO message that needs to be drafted.

The real question is much bigger: what does poor communication actually cost a business?

Silence Has a Price

When employees don't have the information they need, they begin speculating. Relying on informal conversations, they make assumptions and different teams begin working from different versions of the truth.

That is where seemingly small communication failures begin becoming business problems. A duplicated task here. A missed deadline there. Resistance to a new process. A frontline employee who doesn't understand a strategic priority. A manager who hears important information after their team already has.

Individually, these incidents may appear insignificant. Collectively, they create friction and that is expensive.

The Engagement Problem Is Also a Communication Problem

The latest Gallup State of the Global Workplace data provides a sobering picture. Only 20% of employees globally were engaged in 2025, while engagement in Sub-Saharan Africa stood at 19%. South Africa's own engagement figure was 26%, with 65% classified as not engaged and 9% actively disengaged.

These numbers cannot simply be attributed to communication. Engagement is influenced by leadership, working conditions, pay, recognition, career opportunities and many other factors.

But communication sits across almost all of them.

Employees need to understand where the organisation is going. They need context for decisions, access to leaders, and to know how their work contributes to something bigger. When that connection disappears, engagement becomes much harder to sustain.

Gallup estimates that declining employee engagement in 2025 cost the global economy approximately $10 trillion in lost productivity.

The lesson for business leaders is not that communication alone will solve disengagement. It is that communication is part of the infrastructure through which engagement is built.

In Operational Businesses, Communication Can Become a Safety Issue

For South Africa's large operational organisations such as mining, manufacturing, logistics, transport, construction and infrastructure; communication has an even more direct relationship with business performance.

An employee cannot act on information they never received.

A safety instruction that doesn't reach a shift worker. A procedural change that isn't understood. A critical operational update that gets lost between management layers.

These are not merely communication gaps. They can become operational and safety risks.

South Africa's Department of Employment and Labour reported that 36,473 workplaces were found non-compliant with occupational health and safety requirements during the 2023/24 inspection period.

In mining alone, 1,841 occupational injuries were reported in 2024, despite a 16% year-on-year improvement. The Department specifically highlighted repeat accidents and called for employers and labour to be explicit about their respective roles and programmes for maintaining safe working environments.

Communication is not a substitute for proper safety systems, training or compliance but it is one of the mechanisms through which those systems reach people.

Strategy Means Little If Employees Can't Translate It into Action

Walk into almost any large organisation and you will find a strategic plan.

The language is usually impressive: transformation, growth, operational excellence, customer centricity, innovation, sustainability.

But somewhere between the boardroom and the frontline, that language can lose its meaning. An employee may know the organisation's strategy exists without understanding what it means for their role, their team or the decisions they make every day.

This is where internal communication has an important strategic role which is to take a boardroom priority and turn it into something a frontline employee, administrator, engineer, driver, technician, manager or customer-facing employee can understand and act upon.

Because strategy only creates value when people can execute it.

The Most Expensive Communication Failure May Be the One You Can't See

The difficulty with poor internal communication is that its costs don't always appear as a line item on a financial statement.

There is rarely an invoice labelled: “R2 million - employees misunderstood the change.”

Instead, the cost appears elsewhere: unnecessary meetings, duplicated work, employee turnover, delayed projects, avoidable mistakes, resistance to transformation, poor adoption of new systems and managers spending hours correcting misunderstandings.

Sometimes it appears in something even harder to quantify; a workforce that has stopped trusting the information coming from leadership.

That makes internal communication particularly difficult to measure, and particularly easy to underestimate.

Breaking the Silence

For South African organisations navigating transformation, economic pressure, skills shortages, operational complexity and increasingly diverse workforces, internal communication cannot remain an afterthought.

The organisations that communicate well are not necessarily the ones that communicate the most.

They are the ones that make communication useful, timely, relevant and connected to the work people actually do.

Because silence creates a vacuum and when organisations don't fill that vacuum with clarity, someone else will; through assumptions, speculation and informal narratives.

The cost of communication is visible on a budget and the cost of not communicating often isn't, but it is being paid nonetheless.
