Sorry for the rude intervention but...

that's not much because of you or others but the actual management organization is crap. The basic idea is have a workforce, at any level, made of stereotypical Ford-model workers, those who ancient Greek's call "useful idiots", people just able to work but mentally unable to be citizens, to be adult, autonomous. So there is the idea of creating a hierarchy of shepherds to keep the flock "as it should" and that does not work because such social model does not work.
A proof? We have not invented anything really new in the last decades. We have improved anything, popularized anything, but nothing really new have seen the light. Now for the first time in human history after industrial revolution began we see a decline in quality of anything not because of scarcity or war but because of a system that can't anymore sustain itself having consumed itself from the inside.
That's the classic failure of merchants societies: they are skilled in making money, but they only exists if there are some others society to commerce with, different society who develop and produce. Now that everything is commerce...
> I suspect someone with 10+ years experience managing recognizes that all remote, or all in person, are both tenable solutions, but hybrid will cause a separate-and-not-equal workforce schism.
I think it's already there: most talented escape, lest talented start the so called big resignation with vague autarkic attempts doomed to fail and resulting in a mass of future new poor ready to be inserted in the WEF 2030's agenda new society.
Being in person offer benefits form human interaction we can't have on remote BUT have the downside of the physical location need. In a changing world people want freedom and actual cities does not offer that and have no visible chance of improvement. Remote allow living in good place with enough services at interesting costs (at least in theory, in practice for some a bad cold shower of reality for others) trading the less benefit from human interaction to a far more comfortable life. In a society designed around the panem et circense concept at the start of a scarcity era most prefer the circense in absence seen the scarcity of panem...
Beside that, at another level, economy of scale have reached the tipping point of density where we are now too dense and so the scale benefit drop crushed by the density costs. A reset is needed and nobody want to be in the places to be resetted and no one know how will be the new world. So no one want brace the new trying to save resources in classic reactionary moves.
Here the real schism.
