When I was at Google (Kirkland), the offices were basically open-plan fishbowls. WFH was massively better. I once worked at a startup (pre-covid) that had an open-plan setup with a significant portion of people using standing desks. They provided one stool for 2 standing desks justifying it because "if you use a standing desk you should be standing most of the time". Pure cheapskate short-sightedness.
Well, that could be justified as maintaining the health of the employees by forcing one of two to stand up at any time.
I hit that issue when I got my standing desk early during the pandemic, I tend to lock my knees when static and doing that for hours at a time was not good.
