No call, no show

When you have a job, you need to go to work when your boss tells you to. If you can't go to work, you need to call your boss and tell them why. If you don't call your boss, and you don't show up to work, it's called a "no call, no show".

It's like if you have a playdate with a friend, and you tell them you will be there at a certain time. But then you don't show up, and you don't call them to let them know what happened. Your friend might be worried or angry because they were waiting for you.

So, if you have a job, it's important to be responsible and let your boss know if you can't come to work. If you don't, your boss might be upset and you could even lose your job.
