I’ll play devils advocate. Say you work 40 hour work week with 20 hours of “productive” time. If we moved to a 30 hour 4 day work week would you actually only have 15 hours of productive time per week? I say this because I don’t think all the non productive parts of working life would go away, instead we would just get less done.

I agree, and I'm in Toronto, Canada.

I genuinely believe a 4-day work week is the way to go. It's Friday and I'm already burnt out at 11am.

I've recently negotiated a 4-day work week with my employer. It's been a huge quality of life improvement. Whether I make $80k/yr or $150k/yr, it doesn't matter as much to me as quality of life. Maybe I'm an outlier, but money isn't everything.

If smaller companies can't compete on the huge salaries and options that larger companies provide, they can certainly compete on flexible work schedules. A developer working 4 days a week is pretty much just as useful to me as the engineering manager as a developer who is working 5 days a week. Budget and schedule.

if everyone does it, labor will become more scarse, and wages should go back up too to recover the some or all of missing 1/5, so please everyone do this!

Only if total production goes down. If productivity increases enough to compensate (what really looks like the case), it should have no impact on wages.

They certainly can compete. Just raise more or adopt a stock comp model.

Not all companies looking to hire devs have massive injections of VC money to play with.

Tech at this point is needed to some degree in lots of products.

Maybe they need better founders.

If we adopted a four day work week do you think people would feel a burned out feeling at Thursday at 11am? I honestly _don’t know_ and think some long term experimentation is needed

Who cares. Even if I feel just as bad during the week, I have more weekend time. That's worth it.

We don't have a worldwide labor shortage (!). Productivity going up and work hours not going is a travesty.

There's a labor shortage in US right now. You can feel it everywhere: from having to book car mechanic appointment weeks in advance to construction projects going to standstill.

And there's also millions of people that could be working but aren't:

Further, low labor productivity and bad on the job training pipelines directly result from squashing uppity labor

Everyone I've ever known has loved working 4 10's and honestly 4 8's would be even better. They never complain about burnout and a 3-day weekend every week leaves them energized and recharged for the next weeks' work. I only ever hear complaints from people working 4 12's which at that point you'd hear the usual complaints of anyone working 8 hours of overtime a week.

The fact I've never once heard a complaint about 4 10's from anyone I've ever known to work them says a lot compared to the usual 5 8's which I hear complaints from about everyone (including myself).

n = 19~21 people or so

Possibly, but at some point it has to stop, right? Take the extreme example of working 4 hours, one day a week. If you are even marginally interested in what you’re doing, I can’t imagine anyone feeling burned out by that. I just don’t know what the threshold is (and it’s certainly different for different people). A lot of it probably has to do with how busy people’s lives are outside of work, and if they feel like they’re able to manage their lives at least somewhat stress free.

Yeah it would have to stop obviously. But let’s take it the other way! Do you think working 20 hours a day 7 days a week is optional efficiency? We need to find the right balance!

I honestly don't think I would. I am exhausted by Friday and then the weekend is basically just Saturday so there's hardly any time to recharge during it.

I'm not burnt out on Thursdays. I feel empowered. That said, I've only been on a 4-day work week for a month and half now.

Not nearly enough time to adjust. Any job switch the first month is like the honeymoon phase.

My experience is that the burnout and wasted time comes from all the crap that distracts from real work -- the meetings, emails, bug boards, etc. When I don't have all these things getting between me and the IDE, I'm far more productive and get a lot more enjoyment from my work. Of course, if all the crap were cut out, I'd probably be looking at two days of work per week, never mind four.

In the past several years most of the burnout and wasted time I’ve experienced has come from libraries, frameworks, build/CI systems, architectural patterns, and so on that simply suck, or at the very least fail to properly work together. Unfortunately, they’re all mainstream technologies that people seem to think are perfectly okay, and that fighting against your tools simply in order to develop good solutions to the actual domain problems is just what coding is supposed to be.

I'm genuinely curious which of those items you consider as sucky and why. I am asking because I've recently been moved from a C++ to a JS team at my current workplace, and now I am exposed to this wide range of new tools which are all alien to me.

But moving to a 4 day week doesn’t eliminate any of that, it simply means you’d get less done.
