Okay kiddo, have you ever played a game where you have to pick teams and take turns choosing who gets to join which team? Well, that's sort of what happens when a sports team or company needs to choose a new person to hire. They have to pick someone who is really good for the job and who would be a good fit for the team.
But sometimes, people might accidentally only choose people who look like them or who are the same as them. This means that people who are different or who look different might not get a fair chance to be chosen for the job, even if they are really good at it.
So, to make sure that everyone gets a fair chance, some places have something called the "Rooney Rule". This rule says that when a sports team or company is looking for someone new to hire, they have to interview at least one person who is from a different race or culture. This way, they can make sure that they are choosing the best person for the job, no matter what they look like.
The Rooney Rule was named after a man named Dan Rooney, who was really interested in making sure everyone was treated equally. And that's why it's so important to have rules like this, so that everyone gets a fair chance to show how good they are at their job!
