And then there's all the people that didn't know they wanted to work remotely, until they were forced to experience it.
Literally the only people losing in this arrangement are the same parasites who win at literally every other juncture in our society and just, I'm sick to DEATH of it. I will DIE on this hill. I hope the commercial real estate market fucking craters. I hope every company doing this RTO shit dies on the vine. I hope it sucks for every single person in the parasite class who loses more than 2 dollars on everything. I hope it crashes the price of real estate in big cities and makes them affordable again. I hope it makes my home worth less because homes shouldn't be a fucking investment vehicle in the first place.
To borrow the bugs bunny meme, I wish every landlord a very happy get a real job.
So it depends on circumstances and preferences. Both modes should be possible.
But that doesn't solve for the folks behind us on the ladder; how effective are we being at mentoring and growing those people, how easily are they learning the small nuances that we picked up in hallway conversations, serendipitous meetings, and so on. For the company, this is a real concern, but it's harder to measure. To better advocate for remote work, I think we really need to pour more time and energy into this and call out techniques that can be more effective here. For example: having leaders write a weekly newsletter, or getting into the "Why's" much more intentionally when people are remote.
You adapt. The hallway conversations are not some natural world order either. Do you want juniors to pick up skills? When you're starting work on something interesting, post "I'm doing X in (conference link), feel free to join." in a channel. Invite people for a lunch call.
Humans are great at adapting to their surroundings. Mentoring/growing juniors will continue but in a different way that works better for modern work arrangements.
That's why there is resentment. There was resentment before too, but it was more below the radar because it was always shot down with "we work better in person" and there really wasn't much an argument to be had.
But now those people have hard data that they clearly work just as well at home or even better. So now they have data to back up their desires.
