Preaching to the choir. I left my last job because they mandated return to office so that I could work remotely with teams in Montreal and Paris.
The only difference between doing that in my home office and doing it from their office was they could watch over my shoulder from there.
It's not about managing remote teams. It's about controlling workers, and those are very different things. These people are worried that you might be getting your laundry done between work tasks, or that you're actually working 5 jobs, or other ridiculous bullshit, not about whether you're achieving your assigned tasks.
Remote work is cheaper, more efficient, and leads to happier workers, and they'd rather wreck the first two to ensure the don't have the third.
