Part of it's control, part of it is the market seems largely apathetic. The impact of private offices and 4 day weeks is probably small enough that their lack won't kill companies on their own (you don't have to be the best, just good enough), so the effects are still speculative and on a case-by-case basis. Maybe offices and 4 day weeks will slowly trickle into the market place, like remote work pre-covid. But it'll be a generational change, not a revolution. Plus management lives on metrics. If you don't have metrics to capture an impact or potential impact you have no argument. Very few companies currently using open offices/full work weeks are going to expend the capital to experiment with private offices for all and 4 day work weeks. So to make your case at said companies someone else your leadership admires has to do it first and then you can quote them, similar to how every startup office basically turned into a Google knock-off once Google took off.
