Think of a strikebreaker like a substitute player on a soccer team. When some players are unhappy and decide not to play the game, the team still needs to have enough people to play, so they call in substitutes to fill in. These substitutes are the strikebreakers.
Imagine you have a group of friends who always play together, but one day, they all decide to stop playing because they want a new playground. They think if they stop playing, the grown-ups will listen and build a new playground. But then, other kids who weren’t part of your group come and start playing instead, so the grown-ups don’t feel like they need to make a new playground. Those other kids are like the strikebreakers.
In a classroom, if the teacher says there will be no class until new books arrive, but another teacher comes in to teach instead, that new teacher is a strikebreaker. They keep things going even when the original plan was to stop. The main idea is that strikebreakers help keep things moving even when others have decided to pause or stop.
