Amazon started enforcing its so-called “return-to-hub” policy in recent weeks, according to an internal email and Slack messages obtained by Insider. Hubs are the central locations assigned to each individual team — employees will have to work out of those hubs instead of any office nearest to their current city.

Amazon assigned offices for most individual employees, but not the whole team. Some employees told Insider that made office work pointless because many still had to use video calls to connect with their teammates spread across the country.

Why does Amazon even bother to do this? Why force their employees back to office if they’ll going to work remotely with their distributed team anyway? Why not save money on office space by letting those employees to work from their home?
