What’s going to change for the worse in 5 years? If anything people will realize they can work for everywhere and congregate to live next to people they like thereby forming tight knit communities.
Additionaly, study after study has shown that non-verbal communication between people is an enormous part of effective communication. Argue all you want, too many studies, turn all over the weekend she the same thing. And the I've thing that video conferencing does is cripple that comm channel.
I love my partial remote work schedule, and love that it exists. But I'll never assume it's the "best" way, it that it doesn't have unforseen costs to me and my coworkers
Citations please?
Of course the study with the most impact is Mehrabian's 7-38-55 'rule' (which it isn't!). It's wildly misunderstood, but his study found in any communication scenario 7% of information received is through the words spoken, 38% is through the tone of voice, and 55% is though bodily movements. Regardless of the numbers, it just points out that just because someone 'says' something, people don't believe them unless their body language agrees. If their tone, posture, eye-contact, etc.. are saying something else, people invariably believe the non-verbal regardless of the words said. It's been a while, but IIRC, the other studies never find that low of an impact with spoken word, yet it never exceeds 50% either.
Lastly, the definition of nonverbal communications can vary widely, but I like Henley's (77) (as a starting point) which lists a few areas "... body postures and movements, facial expressions, gestures, touching, eye contact, use of space, and so on".
Hope you find some of that useful.
