How to Make Friends at Work: Turning Colleagues Into Actual Friends

DEFINITION

Work acquaintance vs. work friend

A work acquaintance is someone you're friendly with in the professional context but don't have a relationship with outside of it. A work friend is someone where the relationship would survive a job change for either party. The distinction matters because work acquaintances are relationships of convenience; work friends are genuine investments.

Work is, for many adults, the most concentrated source of potential friendships in their lives. The same proximity and repetition that made school friendships easy applies at work: you see the same people every day, you share a purpose and context, you accumulate inside knowledge and shared references over time.

The complication is that work friendships have a layer of professional risk that school friendships didn’t. Getting the tone wrong can create awkwardness that affects your professional relationships. The friend who becomes your work enemy makes every day harder. And there’s genuine uncertainty about where the line is between being friendly and crossing into territory that makes someone uncomfortable.

None of this means work friendships aren’t worth pursuing. It means they require a bit more care.

What makes work the best opportunity for adult friendship

For in-office workers, the structural conditions for friendship are right there: proximity (you’re physically near the same people), repetition (you see them multiple times per week), and at least some shared context (you’re all doing related work in the same organization).

These are exactly the conditions that research identifies as essential for friendship formation. They’re conditions most adults actively lack outside of work. Squandering the opportunity because of professional anxiety is a real cost.

The rough formula for a casual friendship — about 50 hours of shared time — is achievable within a normal work quarter if you invest in even a handful of non-work interactions with a colleague.

The test for whether it can become a real friendship

The simplest way to assess whether a work relationship has friendship potential: have you ever spent time with this person outside of a work context?

Not at a work event, not at the mandatory team dinner — actual outside-of-work time. Coffee that either party could have declined. A walk during lunch. A sporting event. A casual dinner.

If the answer is no, you have a work acquaintance. Work acquaintances are nice. They make the work day more pleasant. They don’t survive job changes on either side and they don’t provide genuine social support.

The transition from acquaintance to friend happens outside of work, and one of you has to initiate it. The invitation doesn’t have to be high-stakes: “I’m heading to that sandwich place on the corner, want to come?” counts.

The boundary question

The professional context creates legitimate questions about how explicitly social it’s appropriate to be at work. Some workplaces are genuinely social; others are more buttoned-up. Power dynamics — manager/report relationships especially — add complexity.

A few principles that tend to hold across contexts:

Peer relationships (same level, no reporting relationship) have the most friendship potential and the least friction around it.

For manager/report relationships, the dynamic is workable but requires care — especially from the manager’s side, where a too-close friendship can create perceptions of favoritism or make it harder to manage performance honestly.

Social invitations work best when they’re genuinely optional and there’s no implicit professional pressure to accept.

Pay attention to reciprocity. If you’re consistently the one initiating and the other person is consistently finding reasons not to engage outside of work, that’s informative.

What remote work changed

Remote work removed the proximity and unplanned interaction that made office friendships form relatively naturally. Video calls work for collaboration; they’re stilted for friendship. You don’t have the hallway conversation, the lunch together, the shared experience of the difficult meeting.

Remote workers who want to maintain work-based social connections have to invest more deliberately: setting up virtual coffee calls that feel genuinely optional and casual, planning work trips to the same city when possible, being explicit about wanting to maintain the relationship outside of work contexts.

For remote workers, the honest advice is: don’t count on work as your primary social opportunity. The structure isn’t there in the way it is for office workers. See how to make friends when you work from home for a more complete treatment.

On how quickly these friendships develop

Work friendships can develop faster than other adult friendships because the repetition is built in — you don’t have to engineer the repeated contact, it happens through work. But the professional overlay means they often develop more slowly emotionally, because the vulnerability that deep friendship requires is more cautious in a professional context.

The transition from “friendly colleague I enjoy working with” to “genuine friend” usually happens through some combination of: spending time together outside work, navigating a difficult work situation together, or one person being honest about something personal that the professional context doesn’t require.

Apps aren’t the first step here

If you’re in an office environment, you don’t need apps to find potential friends. The potential friends are already in your building. The investment is in converting those adjacencies into genuine relationships.

If work has dried up as a social source — because you’re remote, or because you’ve been at a job long enough that the colleague relationships are settled — then apps and community platforms become more useful. For those situations, see best apps for making friends as an adult.
