Oh. People are trying to fit 40 hours into 4 days, or trying to do 5 days worth of work in 4 days? I don't think anyone thought that would be good. 4 day workweek is committing to do 4/5ths less work so that people get less burned out. I don't think it would ever improve productivity (like in terms of "number of tedious todos done" or "number of meetings attended"). Optimizing for long-term mental health should probably be the only goal. (For software engineers, I feel like most of the job is in-the-background thinking, so not having to wake up at a particular time 3 days a week instead of only 2 is definitely going to help that process. But I don't think it will ever scale to "call each customer and exchange pleasantries for 30 minutes a week". There is simply a hard time bound on how much work you can do in X hours with jobs like that, and doing less hours means doing less of those calls. No way around that.)
