I don't know about putting in the least amount of effort for 5 days a week. But what I do know is that in my country, the Netherlands, part-time work is more and more becoming the standard. Already, 75% of women and 30% of men work 32 hours a week or less. In many sectors the fulltime standard has been lowered to 36 hours, which means every other Friday off. I myself started on 40 and will move to 32 hours somewhere…
As far as company / coworker expectations, how does this work? Are responsibilities / work adjusted to fit the hours provided? What about being on-call?
It seems like something a lot of companies should be taking advantage of, but the desire to own souls fights against it.
