The office was dying before the pandemic. Millions of workers had spent years arguing it was inefficient, distracting, and unnecessary. Then everyone went home, and something unexpected emerged from the absence.

What the Office Was Actually Doing

The shift to remote work accelerated at unprecedented speed from 2020 onward, producing measurable productivity gains for many individual roles. Writing, analysis, and focused technical work — tasks with clear inputs and outputs — turned out to work well without the commute, the open-plan noise, and the calendar obligations. For many workers, removing the office was an uncomplicated improvement in measurable output.

What became apparent only in its absence was the range of functions the office had been performing that nobody had named or measured. Random corridor encounters generated ideas that scheduled video calls could not replicate. Informal observation of experienced colleagues — watching how a senior person handled a difficult phone call or navigated a conflict in real time — transmitted tacit knowledge that documentation and training materials cannot capture.

Microsoft’s 2021 Work Trend Index, drawing on anonymized metadata from millions of Teams users, found that professional networks became significantly more siloed during remote work. Teams communicated intensely within their groups but far less across the organization. The bridging connections — the chance encounters and cross-functional relationships — collapsed, along with the information flows those connections had carried.

The Intimacy Problem

Remote work also revealed the hidden role of physical co-presence in trust and relationship formation. Sociological research consistently shows that physical proximity increases liking, familiarity, and trust through a phenomenon called the mere exposure effect. People who share physical space and incidental contact form bonds that are slower and more effortful to build through screens alone.

Employees hired entirely remotely in 2020 and 2021 reported significantly higher difficulty integrating into company culture and lower sense of belonging than those who had joined before the shift. The informal socialization that offices produce — the lunch invitations, the after-meeting corridor exchanges — turned out to be essential infrastructure for new entrant acculturation, and it had never been deliberately designed because it had never needed to be.

The most telling signal came not from surveys but from the companies most committed to remote-first cultures. Automattic, Buffer, and GitLab — organizations with years of remote experience — all invested heavily in periodic in-person gatherings. Their recognition that screens cannot fully replace proximity did not come from nostalgia. It came from direct evidence that something was being lost.

The most analytically honest conclusion is that the office was never a single thing. It was a bundle of functions — focus space, social infrastructure, cultural transmission, chance encounter generator, accountability environment — that were never examined individually because they arrived packaged together. Remote work disaggregated the bundle. Focus work improved for many. Social infrastructure collapsed. Cultural transmission slowed for new entrants. The task now is not to choose between the office and its absence but to identify which of the office’s historical functions actually require physical space to operate, and design environments accordingly.

Most organisations are currently navigating this without the conceptual vocabulary to do it well. Return-to-office mandates that reassemble the old bundle without examining which components were valuable and which were not will reproduce the old problems. Fully remote structures that abandon physical space entirely will continue to lose the bonding, acculturation, and serendipitous encounter functions that screens cannot replicate. The organisations that solve this first will have a structural advantage that has nothing to do with their products.

Remote work made a compelling case for the things the office had been doing wrong: the performative presence, the open-plan noise, the unnecessary commute. The paradox is that it simultaneously made a compelling case, visible only from outside, for the things the office had been doing right.
