Pareto's principle is a simple reality!
A few decades ago in sales, engineering and other disciplines, companies and institutions recognized that 20% of their employees contributed 80 % of the positive results.
On the negative side, 20% of the employees caused 80%+ of the problems.
The smart companies/institutions rewarded the positive 20% and minimized or got rid of the bad 20%.
Then, a few decades ago, the deadly PCism of Affirmative Action took over.
First you could not identify the positive 20% and before you hired them and then reward the top 20% as employees.
Then/now you could not get rid of the 20 % that caused 80%+ of the problems.
Jobs have now become a right! Every employee gets a participation award regardless of lack of any positive contributions.
What is never discussed! Is what is being done to the top 20% of the producers to force them to bring in results to pay for the non producers.
