Discrimination means treating someone differently or unfairly because of something about them that you don't like or disagree with. It's like not wanting to share your toys with someone just because they have a different favorite color than you do.
Employment and Occupation Discrimination Convention is a rule that people made to help stop discriminating against people at work. It is like a guide or a set of rules that employers and workers have to follow to make sure everyone is treated fairly.
The rule says that employers should not treat their workers differently based on things like their race, gender, religion, or disability. For example, if there are two people who are equally qualified for a job, but one is a man and one is a woman, the employer should not choose the man just because he is a man.
The rule also says that everyone should have the same rights and opportunities at work. That means if one person gets a promotion or a raise, everyone who is equally qualified should have the same chance to get it too.
This rule is really important because it helps make sure that everyone has a fair chance to do the job they want and get paid what they deserve. It's not fair to treat someone differently just because of something about them that doesn't affect how good they are at their job.
