The Silent Cost of Workplace Loneliness

"An organization is a group of people coming together to collaborate and achieve something greater than they each might achieve on their own," explains Flo LaBrado, a senior manager at a telecommunications company. "The person is giving something to a collective with an understanding that the organization will also take care of the person."

It's a compact that most organizations claim to honor. Yet despite investments in collaboration tools, team-building retreats, and carefully designed office spaces, something fundamental isn't working. According to Gallup's 2024 State of the Global Workplace report, one in five employees worldwide report feeling lonely at work often—a rate that hasn't budged despite all the interventions.

For this article, we spoke with senior people leaders, including a senior manager at a telecommunications company, a former chief people officer at an international law firm, and an organizational development practitioner. These conversations reveal that workplace loneliness shows up in the metrics leaders already track, why ignoring it becomes costly, and what these professionals are doing to build more connected workplaces.

The Problem Isn't What You Think

Workplace loneliness isn't about being physically alone. It's what researchers Wright and Silard define as "the psychological pain of perceived relational deficiencies in the workplace." You can feel profoundly lonely in an open-plan office surrounded by colleagues if you lack the quality of connection you need to thrive.

For years, loneliness was treated as something individuals needed to manage on their own—a personal struggle separate from organizational performance. The senior people leaders I spoke with for recent research see it very differently. They recognize that how work is structured—the norms, systems, and leadership behaviors—either supports or undermines people's ability to connect and do their best work.

Amy Horn, former Chief People Officer at an international law firm, observes the consequences daily in post-COVID work environments where organic connection opportunities have diminished: "Loneliness has ripple effects on disengagement, presenteeism, and turnover. Where connection is strong, teams show resilience and collaboration; where it's weak, performance suffers. Retention and attrition trends confirm that connected personnel stay, while disconnected personnel leave."

The scale isn't trivial. Workplace loneliness costs UK employers an estimated £2.5 billion annually. A survey of over 5,900 U.S. workers found that lonelier employees reported higher stress-related absenteeism and stronger turnover intentions.

It's Already In Your Metrics

The leaders I interviewed don't need to be convinced that workplace loneliness matters. They're seeing it in data they already track.

Ross Villamil, an organizational development practitioner, observes the pattern at the team level: "When people feel connected, they communicate openly, share ideas, and follow through better. When loneliness sets in, participation drops and performance becomes less consistent."

LaBrado connects this directly to outcomes most organizations already care about: "There's tons of evidence that having a sense of belonging at work is related to psychological safety. People who feel connected and feel psychological safety are more creative and innovative, which of course is related to high performance."

She's right. Amy Edmondson's foundational research demonstrates that psychological safety drives performance through learning behavior—in psychologically safe teams, people engage in more learning behaviors, and these behaviors link psychological safety to better team performance. Loneliness, by eroding psychological safety, quietly undermines the very behaviors that drive innovation and adaptation.

The pattern is consistent across organizations: Workplace loneliness isn't only a well-being issue. It's a core organizational issue that shapes whether teams can collaborate, learn, innovate, and stay.

What Actually Works

The leaders we spoke with agree on two things. First, workplace loneliness won't shift without intentional effort. Second, every organization has its own mix of factors driving disconnection—the goal isn't to copy someone else's program, but to understand what matters in your own context.

In their experience, activities like team-building or social events only work when they sit on stronger foundations: capable leadership, reasonable workloads, and clear ways of working. Without those, you're treating symptoms rather than root causes.

Here's what they've found effective:

• Invest in leader capacity. Train leaders to build connected teams through regular check-ins that go beyond tasks to include how people are really doing. Communication skills matter more than personality—this is learnable.
• Create everyday connection rituals. Embed simple, repeatable practices into the workday: brief check-in rounds, mentoring pairs, peer coaching circles, cross-team projects. Connection becomes a habit rather than an event.
• Support hybrid work intentionally. Build deliberate touchpoints for remote staff with clear inclusion norms for meetings, social time across time zones, and ways to participate informally—not just in formal updates.
• Pair data with conversations. Use engagement surveys and participation rates to spot patterns, then validate them through manager check-ins and focus groups. Numbers show where to look; conversations reveal what to change.
• Normalize wellbeing conversations. Encourage leaders to name stress, loneliness, and mental health as legitimate topics in one-to-ones and team spaces. Position these as part of how the organization sustains performance, not as something separate from "real work."

The Bottom Line

Workplace loneliness is easy to miss until you start looking for it. Once you do, you may realize it's more present in your organization than you thought. That's not a failure—it's useful information.

If you treat loneliness as a serious organizational issue, link it to the metrics you already care about, and respond with intentional, context-aware action, you're moving toward a more connected workplace. The cost of ignoring it—measured in turnover, disengagement, and lost innovation—is too high to justify inaction.

Connection at work isn't a luxury or a nice-to-have cultural feature. It's infrastructure for performance. The organizations that recognize this—and act on it—are the ones where talented people choose to stay and do their best work.
