Is it true that 20% of people do 80% of the work?

Yes, the idea that 20% of people do 80% of the work reflects the Pareto Principle (80/20 Rule), which suggests a minority of inputs (people, efforts) create a majority of outputs (results, work), though it's a guideline, not a strict law, and can be misinterpreted as a rigid fact or an excuse to neglect the remaining 80% of people/tasks. 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.
