not OP too but I'd love to add an extra case: I work 3.5 days/week. I asked my boss after 14 years of work there if I could reduce my working time, given the fact that I think family time is more important. It went well and I suppose it's also thanks to the effort I put into my job daily.

Dunno if you're interested in the whole process, but I documented it on a blog post in case someone is after the same solution (https://givemethechills.com/why-did-i-start-working-part-tim... )

BTW I first got the idea right here on HN and the good thing is that I think, as developers, we have one of the best jobs that allows reducing our working time.

To improve it even further I'd love to do this kind of work entirely remote, thus givin me some extra time to spend with my family and removing the commute. That'd be the max :) I can't ask for this now because we're not a remote company and I know for sure that if the company is not fully remote I'm gonna fail badly (mostly because I'll be the only one doing it ).

In any case, after doing it for many years I can say that it's amazing and I love it
