How HR and Internal Communications Can Drive Business Success

The organisations that consistently outperform their competitors have something in common. It is not always technology, market position, or product. More often than not, it is the quality of their people strategy and the clarity of their internal communication.

The evidence is compelling. According to McKinsey Global Institute, productivity can increase by 20 to 25 percent in organisations where employees feel genuinely connected.¹ Gallup’s research shows that highly engaged business units deliver 23 percent higher profitability than their disengaged counterparts.² Yet the same Gallup data reveals that only 13 percent of employees strongly agree that the leadership of their organisation communicates effectively.³

These figures sit alongside each other for a reason. The gap between what is possible and what most organisations are achieving is not a strategy gap. It is a people and communication gap, and closing it is where HR and Internal Communications working together make the most significant difference.

Why HR and Internal Communications Belong Together

HR holds deep knowledge of the organisation’s people: their motivations, challenges, career aspirations, and engagement levels. Internal Communications holds the tools, channels, and craft to reach those people with messages that land.

Separately, each function has real value. Together, they become something more powerful: a strategic partnership that connects people strategy with organisational communication in a way that drives culture, performance, and measurable business outcomes.

The case for alignment is straightforward. A people strategy without effective communication struggles to reach the employees it is designed to serve. A communication function without people’s insight risks producing messages that miss the mark, technically well-crafted but disconnected from what employees actually need to hear.

When HR and IC work in alignment, the results are different. Change programmes land more effectively. Culture initiatives gain traction. Leadership messages build trust rather than scepticism. And employees at every level understand not just what the organisation is doing, but why it matters and what it means for them.

The Business Case: What the Data Shows

The link between HR and Internal Communications effectiveness and business performance is no longer a matter of professional instinct. It is measurable.

A study of 651 organisations across industries found that companies with highly effective internal communication are 3.5 times more likely to outperform their competitors.⁴ Research consistently shows that companies with strong internal communication deliver 47 percent higher returns to shareholders compared to those with poor communication practices.⁵

The cost of getting this wrong is equally stark. According to Gallup’s State of the Global Workplace report, disengaged employees cost the global economy an estimated $8.8 trillion annually in lost productivity.² The IoIC and Ipsos Karian and Box 2024 IC Index, which surveyed 4,000 UK-based employees, found that where workers rated internal communication as excellent, there was a 40-point boost in engagement.⁶

The business case for investing in the HR and Internal Communications partnership is not a soft one. It is one of the clearest levers available to senior leaders who want to improve organisational performance.

6 Ways HR and Internal Communications Drive Business Success

1. Aligning Employees with Organisational Strategy

One of the most consistent findings in employee engagement research is that employees who understand how their work connects to the organisation’s broader goals are more motivated, more committed, and more productive than those who do not.

This alignment does not happen by accident. Yet the gap between what leaders believe and what employees experience is stark. According to research by Axios HQ, 27 percent of leaders think their staff are entirely aligned with the organisation’s business goals, but only 9 percent of employees agree.⁷

This alignment is the result of deliberate, ongoing communication, led by HR and IC working together to translate strategic priorities into language that resonates with employees at every level of the organisation. When strategy is communicated clearly and consistently, employees make better decisions, prioritise more effectively, and pull in the same direction.

2. Building and Sustaining Workplace Culture

Culture is not built through a values statement on a wall or an annual engagement survey. It is built through the everyday experience of work, the messages employees receive, the behaviours they observe in their leaders, and the degree to which the organisation’s stated values are reflected in how decisions are made.

HR and Internal Communications are the two functions best placed to shape this experience. HR designs the systems, structures, and people practices that make culture tangible. IC ensures that culture is communicated, celebrated, and reinforced through every channel available to the organisation.

Together, they create the conditions for a culture that employees believe in, and that in turn drives the engagement, retention, and discretionary effort that high-performing organisations depend on.

3. Leading Organisational Change Effectively

Change is one of the greatest tests of any organisation’s HR and communications capability. Research consistently shows that the majority of large-scale change programmes fail to achieve their intended outcomes, and that poor communication is one of the leading reasons why. According to an Economist Intelligence Unit survey, communication barriers at work cause project delays or failures in 44 percent of cases, and contribute to low morale in 31 percent.⁸

When HR and Internal Communications collaborate on change management, the picture changes. Employees receive clear, honest, timely communication about what is changing and why. Managers are equipped to have the right conversations with their teams. Concerns are surfaced and addressed before they become resistance. And the organisation moves through change with greater speed and less disruption.

4. Driving Employee Engagement and Retention

Employee engagement does not happen in isolation. It is the product of an environment where employees feel informed, valued, heard, and connected to a purpose larger than their individual role.

HR creates the conditions for engagement through talent strategy, recognition, development, and wellbeing. Internal Communications amplifies and sustains those conditions through consistent, meaningful communication that makes employees feel part of something worth belonging to.

The data makes the case clearly: research shows that companies that focus on communication are 4.5 times more likely to retain their top talent.⁵ And Gallup finds that highly engaged business units see 59 percent less turnover in high-turnover organisations.²

5. Strengthening Leadership Communication

Leadership communication is one of the most powerful drivers of employee trust and one of the most commonly mismanaged. Gallup data shows that employees who feel their managers are good communicators are four times more likely to be engaged in their work.⁹ Yet as noted above, only 13 percent of employees strongly agree that their organisation’s leadership communicates effectively.³

HR and Internal Communications play a critical role in supporting leaders to communicate well. HR identifies the leadership behaviours that matter most to employee experience. IC provides the tools, frameworks, and coaching that help leaders put those behaviours into practice.

Research from the Chartered Management Institute reinforces the investment case: management training delivers an average 23 percent increase in organisational performance and a 32 percent increase in employee engagement and productivity.⁶

6. Reaching Every Employee, Including the Hardest to Reach

Modern organisations are more distributed than ever. Remote and hybrid workers, frontline employees, and global teams across multiple time zones, the challenge of reaching every employee with timely, relevant communication has never been more complex.

This is where the HR and IC partnership becomes operationally critical. HR understands the workforce: its segments, its needs, its challenges, and the moments in the employee lifecycle where communication matters most. IC understands the channels: which formats work for which audiences, how to cut through information overload, and how to measure whether communication is actually landing.

Together, they build communication strategies that reach people where they are, not just the employees who are easy to reach, but the frontline workers, remote teams, and dispersed populations who are often the first to disengage when communication fails.

The Strategic Shift: From Support Functions to Business Drivers

For much of their history, both HR and Internal Communications have been viewed as support functions, important, but not central to the strategic agenda of the organisation.

That view is changing rapidly, and the organisations that have made the shift earliest are seeing the results.

HR Directors and Chief People Officers are now operating at board level, shaping business strategy rather than simply implementing it. Heads of Internal Communications are moving from channel managers to strategic advisors, influencing how the organisation speaks to its people at the most critical moments.

This elevation of both functions reflects a deeper shift in how leading organisations think about competitive advantage. In a world where talent is the scarcest resource, where culture is increasingly a differentiator, and where employee trust is both fragile and essential, the partnership between HR and Internal Communications is not a nice-to-have. It is a strategic imperative.

What High-Performing Organisations Do Differently

The organisations where HR and Internal Communications are most effectively driving business success share several characteristics:

They have a shared strategy. HR and IC do not operate with separate objectives. They align around shared outcomes, engagement, retention, culture, change effectiveness, and measure their success together.

They speak the same language. HR understands the power of communication. IC understands the people strategy. Neither function operates in a silo.

They have senior sponsorship. The partnership is visible at the leadership level. The CHRO and the Head of IC work together, are seen to work together, and bring a unified voice to the senior leadership team.

They measure what matters. Not just activity, emails sent, intranet views, survey completion rates, but outcomes: engagement scores, retention data, change adoption rates, and the degree to which employees understand and believe in the organisation’s direction.

They invest in their people. Both functions are only as good as the professionals within them. The best organisations invest in developing their HR and IC teams through training, professional development, and exposure to the ideas and practices that are shaping the future of both disciplines.
