Okay kiddo, let me explain about workplace privacy in a way that you can easily understand.
When you go to the playground, you might have a secret spot where you like to play alone, right? Well, adults also have some things they like to keep private at work. Just like you have a right to keep your secrets safe, adults have a right to keep their personal information safe too.
Now, when you go to school, you have some rules you need to follow. You can't bully or hurt other kids, and you can't take things that don't belong to you. Those rules are set up to help everyone feel safe and happy. The same is true in the workplace.
But let's say that someone at work noticed you're always talking to your toys during your snack time. Your coworkers might think it's weird, but as long as you're not bothering anyone or being naughty, there's no reason for them to tell anyone else. It's the same with adults at work. If they're not causing trouble, there's no need for others to know everything about them.
However, sometimes grown-ups need to share personal information with their employer so they can do their job. For example, they might need to tell their boss if they're going to be late because their car broke down on the way to work. But even then, the boss should keep that information private and only use it to help their employee.
So, workplace privacy means that adults have the right to keep their personal information safe and that their employers should only use that information to help them do their job better.
