It's quite telling that this is nothing more than an abstract but it has gained votes so fast it hit the top link.

Cue lots of managers using this title to push the 'back to the office' movement a bit further.

There are so many axis other than 'output', and some of them are a lot more important. For instance 'quality'. And 'employee happiness' and 'employee retention'. The term 'human capital' is such a terrible one to use as an abstraction. Capital is something you expend, once you start looking at people as just another resource to make ROI on you're asking to be treated the same way in reverse.

@Dang: suggested title change: "The Power of Proximity to Coworkers: Training for Tomorrow or Productivity Today?"

noobermin•25m ago
The abstract did say the result is mixed. You have "long term" increase in human capital development...primarily because connections help mentor more junior developers, but output is reduced...for obvious reasons.

The "output is reduced" especially for certain crunches where time is of the essence IS an argument for WFH in those circumstances, and for me, when I need the most time alone.

jacquesm•22m ago
The abstract says one thing, the title here suggests an entirely different thing. Besides that not-so-subtle editing, I also find the sample size used more than a little bit lower than one that you could draw such a sweeping conclusion from.
delichon•18m ago
I thought that the title drops the lede somewhat, so my version paraphrases the second sentence of the abstract:

  We find being near coworkers has tradeoffs: proximity increases long-run human capital development at the expense of short-term output.

I’m in a big peer group for managers where a lot of us are remote managers. (Let me repeat before the angry downvotes and comments: I am a remote manager and proponent of remote work)

This was all common knowledge. It has been for a long time. The big companies who tracked a lot of metrics and followed employees from hire onward already knew that remote environments are harder for new people to thrive in. This is why a lot of the companies who did return to office still allow remote work, but they require new hires on-site first and to accumulate a track record of delivering within the company.

It’s also why a lot of full remote companies have gone back to hiring people who already have a lot of remote experience.

The period after COVID where companies hired anyone into remote roles and assumed it would work for everyone was not a good thing for remote work, IMO. A lot of people cannot handle remote work for different reasons: Many don’t communicate well. Some can’t focus at home. Some can’t cooperate with people via text, even though they’re fine in person. Some just want remote work to disappear into the background and respond to a couple emails or Slack messages from their phone while they’re on vacation all the time. It all added up to excessive problems for companies that threw in the towel for RTO.

I know this comment will anger remote maximalists who think everything and everyone should be remote, but we tried that and it didn’t work. I think we’ve overcorrected for now, but the future is probably going to settle into a norm where remote is a limited option for companies and candidates who can handle it, but not the norm for everyone.

candiddevmike•14m ago
What is your definition of "new person" though? If someone has been remote for years, are they still a "new person"? If you trust them enough to hire them, why is there a need to keep earning trust for more privileges. This just seems like a carrot to squeeze some kind productivity or control out of people.
zeryx•8m ago
I've only ever worked remote professionally and I've got a track record, when I apply to a new role there's no question that I can adapt to working remotely at X company.

If I just finished my PhD in comp sci and have never worked professionally in my life let alone remotely, going day 1 remote is a huge risk

Aurornis•2m ago
I knew this was going to turn into a shoot the messenger (or downvote the messenger) situation.

Look, I also work remote and have for years. This is just the situation that’s happening out there. Having 5 years of remote experience no longer means as much because some companies let everyone work remote and waited until now to start firing and laying people off. We’ve hired some real duds into remote roles who had years of remote experience, apparently doing the same thing they tried to do with us: Work a couple hours a week or maybe collect paychecks from multiple jobs.

Every remote manager I know has stories like this. The remote world changed a lot since COVID and the rise of /r/overemployed and “Four Hour Workweek” junk has only made it worse for those of us who just want to work remote without shenanigans.

Aurornis•7m ago
New to the company. Being in-person makes it easier to build new relationships, make friends with people you wouldn’t normally run into in your corner of Slack, and pick up more info about how the company works.

> If you trust them enough to hire them, why is there a need to keep earning trust for more privileges.

In person accelerates onboarding for all the reasons I mentioned above. It’s not a game of trust or “carrots”.

agf•1m ago
Where do companies otherwise prioritize long-run development over short-term output? In my experience, generally nowhere. So why would this make managers push RTO more?

Some who already want RTO may use this as an excuse, but I would think it would actually reduce RTO pressure overall, as it confirms less short-term productivity, which is what companies actually care about.

afavour•28m ago
Makes sense. I consider myself very lucky to have become a senior engineer before COVID. As much as I appreciate WFH flexibility (especially as a parent) I do worry that the next generation of engineers don't have anywhere near the same level of mentorship. I get a lot of mileage out of video conference pairing tools but it's still not the same as sitting together. But I guess I probably am more efficient in the short term when I don't spend so much time on mentorship...

All that said, I still prefer where we are compared to where we were.

The question is what do you mean by proximity? Is this only physical proximity?And does it mean that if you isolate people, but they are within 10 feet of each other they are more productive? And do the results change when there is not physical proximity, but substitutes or alternatives?

It's in the study, generally it's sitting close enough to converse

they didn't study alternatives to proximity, which isn't surprising because I'm not away of anyone that regularly works with a constant audio or video stream active?

From Richard Hamming’s famous speech _You and Your Research_:

> Another trait, it took me a while to notice. I noticed the following facts about people who work with the door open or the door closed. I notice that if you have the door to your office closed, you get more work done today and tomorrow, and you are more productive than most. But 10 years later somehow you don’t know quite know what problems are worth working on; all the hard work you do is sort of tangential in importance. He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.

> Now I cannot prove the cause and effect sequence because you might say, “The closed door is symbolic of a closed mind.” I don’t know. But I can say there is a pretty good correlation between those who work with the doors open and those who ultimately do important things, although people who work with doors closed often work harder. Somehow they seem to work on slightly the wrong thing—not much, but enough that they miss fame.

It's absolutely true that team cohesion impacts results but so do other factors, such as psychological safety [1], work-life balance and flexibility.

And you know what? Employers don't care about any of this, like at all. RTO mandates are nothing more than soft layoffs aimed to suppressing labor costs. Why? Because some people will quit, which is cheaper than severance, and those that remains will have to do their work for no extra compensation and also won't be asking for raises because they fear losing their own jobs. Win win (for the employer).

Profits have a tendency to decrease over time [2]. Investors demand it. To a point you can expand to counteract this. Ultimately though, every company either goes bust or reaches the end-state of having to raise prices and lower costs to maintain profit growth.

Employers are not on your side. We collectively saved companies from going bust in the pandemic by WFH. For tech companies in particular who had had a decade of market-driven increases in labor costs, this turned into a massive opportunity to institute what I call permanent layoff culture. These companies will layoff 5% of their staff every year forever for no other reason to suppress labor costs.

Reminds me of a pair of papers from 25 years ago: Olson & Olson's "Distance Matters" [1] and Teasley, Covi, Krishnan, and Olson's "How Does Radical Collocation Help a Team Succeed? [2].

If I recall correctly the benefits of collocated work only apply when you're actually physically proximal to collaborators. There's not much benefit to just "being in an office" if the people you work with aren't there, and even working with people on different floors doesn't show much benefit which is the part of the research a lot of RTO proponents ignore.

A while ago I worked on a handful of research projects in "virtual collocation" or "computer-supported cooperative work" where the holy grail was to come up with something that made remote teams as productive as collocated ones. It's no longer my area of focus so I haven't kept up on the literature -- I'd be interested in any hard evidence that someone has cracked that.

[1](https://dl.acm.org/doi/10.1207/S15327051HCI1523_4) [2](https://dl.acm.org/doi/10.1145/358916.359005)

This is fascinating, and possibly relevant to companies that hire for the long term. Unfortunately, that excludes most of corporate America.

What about all the time spent commuting? For all the drawbacks of working remotely, the amount of time/energy saved not commuting has to be the most significant. I get more 'focus time' where I can deeply concentrate when I work from home. If I have a commute, I feel frazzled and drained by the time I even step foot in the office.
lenerdenator•3m ago
I will say this: as a person with ADHD, I, personally, am more productive in the office than I am at home. When I was hybrid, I'd go to the local library to work. That also helped.

It's also worth noting that I don't have a family to take care of, and that there are still issues with working in the office, like the commute.

If I had a missus and kids, I might feel differently.
