We’re long past the point of companies doing what’s actually best. Consider how many are returning to offices despite all the evidence that wfh is better for all involved.
As with most things I think a big part of the problem is executives. They live for work. They love coming in and lording over their little fiefdoms and holding pointless meetings where everyone has to listen to them talk. Why would they give up a day of that every week? Why would they let people wfh where they aren’t forced to be in the room making them feel important?
