The King Report is a set of rules that tell companies how to behave nicely and responsibly. Imagine you and your friends playing a game together. There are rules to the game, like no cheating or no hitting, so that everyone can have fun and nobody gets hurt. Well, the King Report is like these rules for companies.
The King Report helps companies to know how to treat their workers, the environment, and the people who buy their things (customers). It also helps them to be honest and tell the truth about everything they do. Just like how you should always tell the truth to your friends and family.
This report was made because some companies were being very naughty and not playing fairly, which was making people unhappy and causing problems. So the King Report was created to make sure everyone plays nicely and fairly in the business world.
