Some high-profile companies like Amazon are mandating all employees return to the office, full time. Justifications, when given, mostly revolve around productivity and innovation. We say, whoa there! The data don’t back up the idea that hybrid and remote work hurt productivity (kind of the opposite) or innovation, and the real justifications likely lie elsewhere.... Read more »
