This realization actually caused my last company to full 180 on their WFO policy to "Fuck it work wherever you want in the world, including in one of our offices. Just give us two weeks heads up if you move so we can sort out the taxes."
But that's exactly what the parent posts have issues with. The false claim that the WFH people are letting everyone do what they want while the WFO's are not letting everyone do what they want.
Because the WFH people are forcing the WFO people into zoom meetings. Having to dial in individually because you say that's "good policy" takes away the thing that WFO people want: To not sit in zoom meetings all day.
Example: my old team
Half in Boston and half in Barcelona. Standups were joined by people at both offices and were done with Zoom in 2 conference rooms because even though everyone was WFO, we still need to do video conferencing. Unless you want to restrict teams to being in the same office.
Something often missing from these discussions is that at many large companies, A lot of people are scattered around the country/world so, even if they are in an office, a lot of meetings are going to be by Zoom anyway. And frankly, if some people are going to be remote, it's good policy that people generally dial in individually if it's an interactive meeting.
So this isn't necessarily a WFH/WFO thing. Decades before there was a Zoom, at least half the meetings I was in had lots of people on a conference call.
