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!

> If smaller companies can't compete on the huge salaries and options that larger companies provide, they can certainly compete on flexible work schedules.

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

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.

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.

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.

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

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.

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