Okay kiddo, let's talk about something that's really important, but can be a little confusing. Sometimes, when workers want to form a group called a "union" to protect and fight for their rights at work, some people try to stop them using violence. This is called "anti-union violence".
Now, why would someone want to stop workers from forming a union? Well, it's usually because the business owners or managers don't want to give the workers better pay, benefits, or working conditions. They might be worried that if the workers form a union, they'll ask for these things and the cost of running the company will go up.
Unfortunately, sometimes these people will go to extreme lengths to prevent workers from forming a union. They might hire people to threaten or hurt workers who want to join the union or speak out against the company. They might even fire workers who talk about forming a union.
This is very wrong and very dangerous. It's important for everyone to have the right to form a union and stand up for their rights. That's why there are laws that protect workers who try to form a union, and punish anyone who uses violence or intimidation to stop them.
So remember, kiddo, workers have the right to form a union, and nobody should use violence to stop them.
