Up or out

Up or out is a system where people have to move up the career ladder or leave their job within a certain time period. It means that if you want to keep your job, you need to get promoted to higher positions every few years. If you don't get promoted, you have to leave your job and find another one.

Think of it this way: you start playing with blocks, and you're really good at putting them together. But after a while, your parents tell you that you need to start building bigger things, like towers or castles. If you can't build anything bigger, you have to stop playing with blocks and find a new toy to play with.

This is similar to how up or out works. You start at a job and do a good job at it, but eventually, you need to move up and take on more responsibilities. If you do well and get promoted, you get to keep your job and continue building your career. But if you don't get promoted, you have to find a new job and start over somewhere else.

Up or out can be tough because it puts a lot of pressure on people to constantly improve and learn new things. But it can also be helpful because it encourages people to work hard and strive for success.
