The point isn't efficiency, the point is greed. Efficiency doesn't make money, it's idealistic. Office managers literally need people and an office in order to do anything. What are they going to do all day when no one needs pens or snacks or in-person administration? Assistants have nothing to schedule (except zoom calls) when people aren't travelling or going to in-person meetings. Amazon has already spent millions on building huge offices all over the world and has to justify it's use or else they sit empty and don't generate any revenue or business. Middle managers and project managers can still be remote since much of what they do is just email, but some of those guys need to see people working in office in order to have their power trips. The real reason these middle managers are demanding RTO so hard is specifically because people are actually MORE productive at home, which means that their jobs are on the line since there's no whip to crack. Who needs a slave driver when the slaves all hit their metrics?
