“Our results show that firm-wide remote work caused the collaboration network of workers to become more static and siloed, with fewer bridges between disparate parts.”
The data is 61,182 Microsoft employees and their email, calendars, chats and calls. People kept talking to their own team and stopped talking to everyone else. The study measured the first six months of 2020, in a pandemic. It will get quoted forever as proof that remote work fails, by executives who want the office leases to pay off.
