What is the 100 80 100 rule?

The 100-80-100 rule is a model for the four-day work week: 100% pay for 80% of the time, in exchange for maintaining 100% productivity, a framework promoted by 4 Day Week Global to boost efficiency, work-life balance, and focus by reducing hours without reducing compensation.

It's a useful mental model for focusing on high-impact activities, but blindly applying it can lead to bad management by ignoring other contributors or essential but less "productive" tasks, according to this Inc.com article.
