I live in the US. As a rule, I work a four day week with a three day weekend. I’ve turned down jobs because they didn’t offer it as an option.

Unfortunately, the week I work is 4x10. I’d certainly rather have one day a week rather than two hours a day, but both would be far preferable.

I still end up regularly logging in on Fridays because of people with unimportant meetings and inflexible schedules.
