What the data actually shows
The most-cited evidence comes from Gallup, whose long-running engagement research includes the deliberately worded item 'I have a best friend at work.' It is one of their twelve key engagement questions, and Gallup reports that agreeing with it is consistently associated with higher engagement, better performance, and stronger retention. The item is famous partly because it surprises people — yet it keeps predicting outcomes across large samples.
Beyond Gallup, a broader body of research on workplace social support points the same way: people with supportive relationships at work tend to report lower stress, more enjoyment, and greater willingness to stay. Social connection appears to buffer the strain of demanding work rather than simply making it pleasanter.
It is worth being precise about what the data is. Most of it is correlational — engaged, well-supported people may both seek and sustain work friendships — so the arrow is not purely one-directional. But the association is robust, consistent across years, and aligns with what we know about social connection and wellbeing generally.
Why this feels different from how it actually is
Work friendships feel like a distraction from 'real' work because the dominant cultural model treats a job as a transaction — effort for pay — with relationships as a pleasant side-effect at best. That framing makes the engagement link feel almost counterintuitive, even though the research keeps confirming it.
There is also a quiet assumption that professionalism means keeping colleagues at arm's length. So the value of closeness gets underweighted, while its risks — gossip, favouritism, awkwardness when things go wrong — feel vivid and memorable. The downside is easier to picture than the steady, invisible benefit.
Remote and hybrid work sharpen the gap between how much connection matters and how easily it forms. When the casual, unplanned moments that build friendship disappear, the absence is easy to rationalise as fine — but the engagement research suggests something genuinely useful is being lost, not just something nice.
Connection at work is not a soft extra; it is closely tied to how good the work actually feels and how long people stay.
What the research says to do about it
The practical implication of the engagement research is to treat connection as worth a little deliberate effort rather than leaving it entirely to chance — particularly in remote and hybrid settings where the unplanned moments that spark friendships rarely happen on their own. Small, repeated, low-stakes contact is what the social-support literature suggests builds real relationships.
For organisations, the evidence favours conditions that let friendships form — stable teams, time for non-transactional interaction, and in-person or synchronous moments — rather than forced 'fun.' The finding is about genuine connection, which cannot be mandated, only enabled.
It also helps to manage the trade-offs openly rather than avoid closeness to dodge them. Being clear about boundaries, keeping work decisions fair, and not letting a friendship distort professional judgement lets you keep the documented upside while limiting the realistic downsides.
What the research says does not help
Treating work friendship as unprofessional or a distraction does not help, and runs against the evidence. The research consistently links genuine connection to engagement and retention; keeping everyone at a deliberate distance forfeits a benefit rather than protecting performance.
Forced or performative team bonding — mandatory socials, scripted 'fun' — tends not to produce the real connection the data is about, and can backfire by feeling hollow or obligatory. The finding concerns authentic relationships, which can be enabled but not manufactured on command.
Assuming remote work makes connection unnecessary is a common but unsupported leap. Remote work makes friendships harder to form, not less valuable; the engagement link still holds, which is precisely why the loss of casual contact is worth actively compensating for rather than shrugging off.

What this looks like in real life
The 'best friend at work' question that surprises people
Gallup's deliberately worded item — 'I have a best friend at work' — sounds too soft to belong in a serious engagement index, which is exactly why it is famous. Yet it keeps predicting higher engagement, better performance, and stronger retention across large, long-running samples. The framing feels counterintuitive; the association does not go away.
Working remotely, rationalising the silence
When the casual, unplanned moments that build friendship disappear on a remote team, their absence is easy to rationalise as fine. But the engagement research suggests something genuinely useful is being lost, not just something nice — which is why deliberate, low-stakes, repeated contact is worth the effort rather than left to chance.
Real numbers in context
Gallup's 'I have a best friend at work' item is one of twelve in its core engagement index, and the firm reports it as consistently associated with higher engagement, productivity and retention across very large, long-running samples. It is best read as a strong, repeated association rather than a single precise effect size, since results vary by workplace and study.
The wider context is that engagement is scarce — Gallup has put the share of actively engaged workers worldwide at only around a fifth in recent years — which makes the factors that reliably raise it, connection among them, more notable, not less. Against a backdrop of widespread disengagement, a genuine friend at work is one of the more dependable bright spots in the data.
