What the heck is the difference between union and non-union when it comes to work and why does everyone seem to majorly prefer union?

Question

Seriously, I’ve heard so many people cheer on union but when I search up what it is I don’t understand it in the slightest bit.

Please, explain like I’m five.

Answer 1

Others have described what unions are. I am only adding a comment to say that many people are not for unions. So your title “why does everyone seem to majorly prefer union” is not necessarily accurate.
