I see the 4-day week as a desirable perk that may be available within high-performing organizations. Modifying pay is probably more a bargaining chip for ICs who are working 4 days when others are not.

Outside of knowledge work, the 4-day week appears where demand outstrips supply. It's pretty common for dental offices, an one example, to work 4 days _just because they can_. The bos can pay themselves several hundred thousand dollars a year and pay their staff competitive salaries without giving up their long weekend plans.

tbh I was surprised to hear it myself. I work in an agency for a client 100% of my billable time. I don't work on Fridays where I certainly would've continued my day-to-day tasks. I'm kind of a tech lead on things (it's a little fuzzy) so as long as I've got things stacked up enough for the rest of the team and people are unblocked, work continues. I think they meant it in a "we haven't had to slow down or get blocked" sort of way.

I think it mainly speaks to the fact that "most stuff is not actually critical". So people have adapted accordingly and the work that needs to be done, is done, and that which isn't so pressing can wait.

Kind of amazing that they just admitted that freely.
