K-pop contracts are notoriously known for being unethical and often dubbed slave contracts
Suing companies has always been a thing in K-pop but it feels more common or mainstream than ever!
I don’t know South Korean law so I’m not entirely sure what’s possible but I have a feeling companies will start including idols will be unable to take legal action against said company for the next X amount of years
Basically idols will give up their legal rights once they sign. It’s made even scarier because you have a group of teenagers with a dream of becoming successful and famous and will often breeze past the contracts and some guardians don’t check either (unless made public knowledge which it wouldn’t!)
