I think this generalizes: Engineers right now are negotiating from a place of power when it comes to employment. It's just that for whatever reason, our current employer at any given time usually struggles to see that. So we can ask for things and very well might get them (whether that's compensation, work-schedule, or something else), but we're going to have much better luck doing that at the time of getting a new offer (while still employed). That's where our negotiating power comes into focus for the other party. For you it was a four-day work week, for me it was getting them to drop the overbearing inventions-ownership clause in my contract. But I think that, if there's anything important missing on a person's work-life wishlist, this is the way to go about getting it.
