What is the 100:80:100™ rule for the 4 day week?

We believe that a 4 day week is a 32-hour week, or 4x8-hour days of work. While many of the companies which trial the 4 day week decide to adopt the Friday-off model, this doesn’t necessarily work for all.

Different industries require different approaches. For example, organizations introducing a 4 day week to customer service centers would need to rotate the day off among their staff so as to maintain service levels.
