🌈 The Big Picture

Korean work ethic vocabulary is the vocabulary of professional praise — and professional feedback. 성실하다 describes someone's fundamental commitment. 꼼꼼하다 describes their working style. 책임감 is what shows up under pressure. 확실히 is how they communicate. And 태도 wraps it all together.

These five words appear in every Korean job interview, performance review, and colleague description.

🎨 The Core Work Ethic Family

1. 성실하다 — diligent, sincere in effort, earnest 💪

성실한 사람 = a diligent person. 성실하게 일하다 = to work diligently. 성실히 노력하다 = to make sincere efforts. More than just "hard-working" — implies genuine commitment and earnestness.

2. 꼼꼼하다 — thorough, meticulous, detail-oriented 🔍

꼼꼼하게 확인하다 = to check thoroughly. 꼼꼼한 사람 = a detail-oriented person. 꼼꼼히 챙기다 = to carefully look after. Not about speed — about not missing anything.

3. 책임감 — sense of responsibility 🎯

책임감이 강하다 = to have a strong sense of responsibility. 책임감이 없다 = to lack a sense of responsibility. 책임감 있게 일하다 = to work with a sense of responsibility.

4. 확실히 — clearly, definitely, for sure ✅

확실히 전달하다 = to communicate clearly. 확실히 해 두다 = to make something clear. 확실히 알다 = to know for certain. Both "definitely" and "clearly."

5. 태도 — attitude, manner, bearing 🌟

태도가 좋다/나쁘다 = attitude is good/bad. 태도를 바꾸다 = to change one's attitude. 일하는 태도 = work attitude. The most visible signal of work ethic.
