I think it's more a matter of expectations. I've worked OT non comp places that will still expect you to do hotseat outside of hours, deal with fires, or regularly come in early/stay late "lest you look like a slacker." This often isn't even institutionalized, but just some sort of weird culture that's built up around time spent "looking busy" corresponding in some inane way to being a productive employee. If you're making the choice yourself, fine. But if you're being pressured to work past that boundary, it may be as the parent poster said, a canary, if not for the whole company, but how the company culture will play in concert with your own personal choices/life balance.

Agreed - a push to confirm in a way that is not desirable creates the opposite effect. And this is actually pretty common - expecting folks to work on weekends, be available to reply at all times and so on.

Working beyond 40 hours is non-productive is a rhetoric I see often on Hacker news. And it always blows my mind. My life experience has been exactly the opposite.

The parent article does not state it as a requirement - more so as a nature of reality for the more ambitious folks in the startup vs. corporate category. I find exceptional folks in my company to be also very hard workers - by choice and not by force. And there are plenty who live a precise 40 hour schedule. Which is fine for both parties as long as that's what they want. What I find pretty ridiculous is the very common new-agey declaration that there is only one right way for everyone which is "40 hours of work" and anything else is just a waste of time. I think it is a very appealing life-style for many - but not a reality for many people who want to get ahead in their careers, are ambitious or are attached to the nature of their work. I see nothing wrong with that.

There's a risk in it though, and this is what I always try to stress. While I certainly accept there are many people who can work more hours, and do, (I do, if it's a project I care about) this can still set a precedent that "leaks" onto the other employees through that potentially subconscious expectation setting I mentioned. In short, you don't only have to worry about what you can handle, but if your behavior will put the rest of your team between a rock and a hard place.

This may be a "dangerous" thing to suggest, since I realize it edges on a "if no one does exceptional work we all look fine" mentality which certainly isn't productive, I just mean to stress that buying into 40< hours may have ripples in terms of legitimizing it as a Carte Blanche system, (Yes, this is a slippery slope argument, but having seen it pan out as I've described I'm less hesitant to lend it credence.) and as you say, an appealing life-style for many, or some, certainly might not be for all.
