at the seams when it's mentioned.

Full disclosure: I prefer working in the office rather than at home, but I see the big picture and recognize the big benefits from having as many people WFH as possible. I've worked with many, many people in my career that are remote from me or working from home and I haven't seen any of the supposed concerns raised ever cause significant problems. In fact, every company I've ever worked for has been spread across multiple sites (including homes).

In my research, the unsolicited, unprovoked outrage appears to mainly stem from a couple of sources:
1) People that have jobs that must be done in person, apparently lashing out based on frustration that others are able to do that.
2) Managers that have long since left line level production and have discovered that their tradition of management by walking around has been damaged. It becomes clear that they don't actually produce much value for the company, and thus they are concerned. It is in their best personal financial interests to get people back into the office, and they willfully ignore the large societal benefits for purely selfish reasons. The feeling is understandable in some ways, but the vitriol, cynicism, and personal attacks that almost always accompany this are astounding and completely out of line.

I think that's what's shocking to me - how angry people get about it and lose their sense of decorum.
