저도 구글에 힘을 빌려서 찾아봤는데요
Comprehensive wage system 라고 하면 되지 않을 까 합니다.
There is a comprehensive wage system in Korea.
Employees get paid overtime, but actually, it was included in their annual salary already.
So employers can make employees work overtime without real allowance while they can avoid the law cleverly.
사전 찾아가면서 해서 공부가 되긴 하는데, 어렵네요ㅠ.ㅠ 도움이 되었음 합니다^^

감사합니다.

너무너무 도움되었어요
