The effects of remote work on collaboration among information workers

Brief summary: This study analysed a large database of emails, calendars, instant messages, video/audio calls and workweek hours routinely generated by 61 182 US Microsoft employees in the months before and after 4th March 2020, when the company mandated that all non-essential employees change to full-time working from home (WFH). Remote working led to more 'siloed' work groups, fewer phone calls but more e-mails.
