As a boss of quite a large team, I think it's ok to not have everyone be hyper productive 5 days a week and I don't want people cramming 5 days of work in to 4. I want a little slack and room to pivot for my team during the week. I need people to have a spare few hours in the week that they maybe feel is unproductive in order for them to be able to pick up a couple new things that crop up. I'm not able to schedule 40 perfect hours of tasks for people to start on from 9am Monday. Where are as a team Friday 3pm looks very different to where we'd be Thursday 8pm if everyone was nose to the grindstone the whole time.

Also if youre a business that is basically a team for hire to a client who works 5 days a week, what do you tell them when they come up with some valid but urgent request during "normal" business time and that key person isn't there because they've already done their 40 hours. "Sorry we'll have to pick that up next week" very often doesn't fly with them ("what do you mean that person only does 4 days a week, we need that thing done today" is not a conversation I want to have). I cannot always afford to hire more people to cover that unicorn 10x team member who wants to work 4 days.
