Imagine you have some toys and you and your friend want to play with them. But you can't agree on who gets to choose which toys to play with first. You both want to play with your favorite toys and you don't want to share them. This makes you angry and upset.
The same thing happened to grown-ups who worked at a big newspaper company called The Washington Post in 1975. Some of these adults were called pressmen, and they were in charge of printing the newspaper. They had a disagreement with the company's bosses, who were also grown-ups, about how much money they should be paid for their work and other important things like working hours and benefits.
The pressmen wanted to be paid more for their work because they thought they deserved it. But the company didn't want to pay them more because it would cost a lot of money. So, they couldn't agree on how much the pressmen should be paid.
This led to a big argument, and the pressmen went on strike, which means they refused to work until they got what they wanted. This meant that there was no one there to print the newspaper.
People were very upset because they couldn't read their favorite newspaper. The company tried to hire other people to do the printing, but the pressmen's union, which is like a group that protects workers' rights, didn't allow them to.
After a long time, both sides finally came to an agreement. The pressmen got some of the things they wanted, but not all of them. And the newspaper started to get printed again.
So, just like when you and your friend argue about your toys, sometimes grown-ups argue too. But, just like you and your friend can talk things out and find a solution, grown-ups can also do the same. And that's exactly what happened with The Washington Post pressmen's strike.
