Early in our 2018 experience with the 4 day week in our business Perpetual Guardian, we came across the problem which a lot of you also find. We can’t all take Fridays off; or, we don’t want to. What do we do with people who are already working four days or less, or those who are working more than 40 hours? I sat down with our team and we came up with our 100-80-100™ principle.
