As companies debate the impact of large-scale remote work, a new study of over 61,000 Microsoft employees found that working from home causes workers to become more siloed in how they communicate, engage in fewer real-time conversations, and spend fewer hours in meetings.

The study, published in the journal Nature Human Behaviour and co-authored by Berkeley Haas Assistant Professor David Holtz, used data from before and after Microsoft imposed a company-wide work-from-home mandate in response to the COVID-19 pandemic. The findings suggest that a full-time remote workforce may have a harder time acquiring and sharing new information, affecting productivity and innovation among information workers down the road.

‘Measuring the causal effects of remote work has historically been difficult because only certain types of workers were allowed to work away from the office. That changed during the pandemic when almost everyone who could work from home was required to do so,’ said Holtz, who conducted the research as an MIT Sloan doctoral intern at Microsoft and co-wrote the paper with Microsoft colleagues Longqi Yang, Sonia Jaffe, Siddharth Suri, and seven others.

‘The work-from-home mandate created a unique opportunity to identify the effects of company-wide remote work on how information workers communicate and collaborate.’

The analysis was based on anonymised data describing the emails, instant messages, calls, meetings, and working hours—all stripped of their content and identifying information—of the overwhelming majority of Microsoft’s US employees.

Holtz, a faculty affiliate at the Berkeley Institute for Data Science and research affiliate at the MIT Initiative on the Digital Economy, said that while the pandemic offered a rare opportunity to study the impact of firm-wide remote work, significant effort was required to understand the extent to which changes in behaviour were caused by remote work in particular rather than the upheaval of the pandemic itself. After all, workers suddenly found themselves navigating shelter-in-place orders and supply shortages, caring for children home from school or vulnerable relatives, and coping with general stress and anxiety.

Microsoft, where 18% of employees were working remotely before the company issued its work-from-home mandate, offered the opportunity for comparison. The authors separated the effects of remote work from other effects of the pandemic by using a statistical technique to compare those Microsoft employees who were already working from home with those who abruptly shifted online during the pandemic.

The researchers had access to anonymised data on employees’ roles, managerial status, business group, length of tenure at the company, and what share of their co-workers were remote before the pandemic; they matched groups of workers with similar observable characteristics. They also used aggregated weekly summaries of the number of time workers spent in scheduled and unscheduled meetings and calls, the number of emails and instant messages they sent, the length of their work weeks, and monthly summaries of workers collaboration networks.

Key findings

  • Company-wide remote work caused workers’ collaboration networks to become less interconnected and more siloed. They communicated less frequently with people in other formal and informal business groups.
  • Remote work caused workers to spend about 25% less time collaborating with colleagues across groups than pre-pandemic levels. Remote work also caused workers to add new collaborators more slowly.
  • Conversely, remote work led workers to communicate more frequently with people in their inner network and build more connections within that inner network.
  • Remote work caused workers to spend more time using asynchronous forms of communication, such as email and message platforms, and less time having synchronous conversations in person, by phone, or video conference.
  • Remote work also caused the number of hours people spent in meetings to decrease by about 5%, suggesting that the increase in meetings many experienced during the pandemic was not due to remote work but other pandemic-related factors.

Holtz said: ‘The team was also able to separate the effects of company-wide remote work into two separate components: how your own collaboration patterns are affected when you work remotely and how your collaboration patterns are affected when your collaborators work remotely. They concluded that both are important.’

‘The fact that your colleagues’ remote work status affects your own work habits has major implications for companies that are considering hybrid or mixed-mode work policies,’ he said. ‘For example, having one’s teammates and collaborators in the office simultaneously improves communication and information flow for both those in and out of the office. It’s important to be thoughtful about how these policies are implemented.’
