수고하셨습니다: The Phrase That Ends the Korean Workday

Stay in a Korean workplace until the end of a day and you will hear one phrase more than any other.

수고하셨습니다.
sugohasyeotseumnida

It closes the shift. It closes the meeting, the shoot, the group project, the move. There is no clean English equivalent — “good work” is too evaluative, “thanks” is too thin, “well done” sounds like praise from above.

What it is made of

수고 is effort, or trouble taken on someone’s behalf.

• 수고 + 하다 → 수고하다, to take trouble / to work hard
• + -(으)시- → 수고하시다, raising the person you are addressing
• + -었- → 수고하셨 — it is finished
• + -습니다 → 수고하셨습니다

Every piece is doing work. The honorific infix says I am elevating you. The past tense says the effort is complete. The formal ending sets the register.

Change the last two pieces and you change who it is for:

That last one matters. To a delivery driver, a security guard, a shop assistant — anyone mid-task — it is 수고하세요, not 하셨. Their work is not finished.

The mistake worth knowing

Traditionally, you do not say it upward.

Assessing someone’s effort is something a senior does for a junior. Saying 수고하셨습니다 to your boss technically puts you in the position of evaluating them.

To someone above you, safer options:

들어가세요. — Head on home.
안녕히 가세요. — Goodbye.
먼저 가 보겠습니다. — I’ll head off first. (said when you are the one leaving)

In practice many workplaces have softened this, and in some it passes without comment. But the rule is real enough that it is worth watching what colleagues actually do for a few weeks before joining in.

The warmer sibling

고생하셨습니다 uses 고생 — hardship — instead of 수고.

수고하셨습니다 — you put in effort.
고생하셨습니다 — that was rough, and you got through it.

After a genuinely difficult day, a long move, a hard negotiation, 고생하셨습니다 lands with more warmth. It acknowledges the cost, not just the labour.

Same restriction applies upward.

Where else it turns up

It is not confined to offices. The phrase closes any shared effort:

• Film and TV sets — it ends every shooting day, and you will hear it in behind-the-scenes footage constantly
• Group projects — students say it to each other
• The military — ritually
• Any task done together — a move, a long drive, an event

What it requires is not work in the employment sense but something finished together. That is why it feels strange after coffee with a friend, and natural after four hours of helping them move flat.
