In my view, the mainstream mass-office environment is the result of something like an evolutionary process -- a series of gradual adaptations to changing conditions. And management habits subsequently adapted themselves to that environment.
Some of those conditions no longer exist, but like Chesterton's fence, we're hesitant to get rid of the physical and cultural manifestations of the mass-office if we can't figure out why it existed in the first place.
One seemingly obvious reason was that people needed access to the tools and materials of their work. (Before ca. 1990, information was a "material"). And there was really only one practical means for workers to interact and share information in groups.
The rest is history. ;-)
Some people adapted their work and life to the mass-office, others didn't. The person whose day care is across the street from the office has made such an adaptation. For others, the mass-office was a hell that they tolerated because they needed the money, e.g., with continual distraction and hours of commuting per week as a form of unpaid labor.
Then the pandemic threw everything into disarray and pressed a giant Reset button.
Today, I think it's fair to say that we don't know what works. The mass-office worked for some but not others. I have little doubt that working from home will work for some but not for others. None of us know what new adaptations will emerge, or how management will adapt.
So far management wants to hang onto the habits that they were familiar with, so they want us back in the office, but they can't articulate why. The "collaboration" argument was used to herd us into open plan offices, with a possible negative effect on collaboration, so that card has been played.
We don't know what management techniques will work in the new environment. The factory style "line foreman" was an easy role to fill with a large cadre of minimally educated workers. At my own workplace, the teams that transitioned the most successfully to remote work were the ones where people were largely self directed in the first place.
