Look beyond the individual desk
The Microsoft study examined connections between workers, rather than testing a weekly hybrid schedule. It compared changes among previously remote and office-based employees, using assumptions about how the groups would otherwise have changed. That helps address pandemic effects, but does not make the study a randomized trial.
This is a suggested direction based on archival research, not a promise of a future discovery. No automatic monitoring has been started.
Reported finding: Connections can change too
Reported findingA separate analysis of 61,182 US Microsoft employees estimated that company-wide remote work made collaboration networks more inward-looking, with fewer links across groups.
Scope and conditions: This was a pandemic-era natural experiment, not a trial of two home days. It did not directly measure productivity or innovation.
Source passage · 2021The analysis uses a modified difference-in-differences model. Its causal interpretation depends on assumptions including parallel trends. The October 2021 correction fixes a direction label in Fig. 1.

Answer in this version
The Microsoft study examined connections between workers, rather than testing a weekly hybrid schedule. It compared changes among previously remote and office-based employees, using assumptions about how the groups would otherwise have changed. That helps address pandemic effects, but does not make the study a randomized trial.
What remained unresolved
An informative next experiment would vary shared office days across teams and follow new collaborations, mentoring and work quality over time. That is a research proposal, not a result of these studies.
Takeaway and scope
At Trip.com, the option to work from home helped employees stay.
A hybrid-work trial at Trip.com, with a separate study of fully remote work at Microsoft.
Fewer employees left
Among 1,612 employees, departures during the 2021–2022 trial were 4.8% with the hybrid option and 7.2% without it: 2.4 percentage points lower, or one-third in relative terms.
The offer allowed home working on Wednesday and Friday; assignment used odd or even birthdays.
Performance grades held up
The first review period showed similar performance grades. Equivalence tests ruled out average differences as large as half a grade in either direction on the five-point scale.
That does not establish identical performance or measure every aspect of work quality.
Connections can change too
A separate analysis of 61,182 US Microsoft employees estimated that company-wide remote work made collaboration networks more inward-looking, with fewer links across groups.
This was a pandemic-era natural experiment, not a trial of two home days. It did not directly measure productivity or innovation.
