수고하셨습니다: the phrase that ends every Korean workday

It’s 6:02 p.m. You’ve saved your file, closed your laptop and put on your coat. Now comes the hardest part of the Korean workday: getting from your desk to the door.

You stand up. A few heads lift. You open your mouth, and out comes the sentence every Korean office runs on:

“수고하셨습니다!” (su-go-ha-syeot-seum-ni-da)

Your teammates call it back. Someone you have never actually spoken to calls it back from behind a monitor. It ripples across the floor like a Mexican wave of politeness, and you walk out into the evening, done.

Unless, of course, your team leader is the one still sitting there. Because there is a small but very real chance that, somewhere in that office, someone has just thought: “Did the new hire just tell me ‘good work’?”

Welcome to the most-used, most-loved and most-argued-about phrase in Korean working life.

The short version: 수고하셨습니다 literally means “you have taken trouble” or “you put in effort,” and in practice it means “thanks for your work, we’re done here.” Koreans say it when leaving work, at the end of a meeting, to a taxi driver, to a cashier, and to students after an exam. The catch: Korea’s National Institute of Korean Language, in its etiquette guide 표준 언어 예절, says it isn’t appropriate for a junior to say it to a senior, because it can sound like you are grading their effort. Plenty of Koreans say it to their bosses anyway. If you want to be safe, say “먼저 들어가 보겠습니다” (“I’ll head off first”) or “내일 뵙겠습니다” (“See you tomorrow”) to people above you, and save 수고하셨습니다 for peers, juniors and everyone who has just done something for you.

What it actually says

Start with the noun. The Standard Korean Language Dictionary defines 수고 (su-go) as “putting in strength and taking pains to do a job, or that hardship.” So 수고 is effort with a little sweat on it. Not tragedy, not suffering. Just the honest strain of getting something done.

Then the grammar does its thing:

Korean	Literally	What people mean
수고했어	“You took trouble.” (casual)	“Good work.” To a friend, a younger colleague, your kid after an exam.
수고했어요	Same, polite	Friendly, to peers or people slightly below you.
수고하셨습니다	“You (honored) have taken trouble.” Formal, past	“Thanks for your work today.” The office closer.
수고 많으셨습니다	“You took a lot of trouble.”	Extra warmth, after a long project or a hard day.
수고하세요	“Please take trouble.” Polite, present	“Keep up the good work,” said by the one leaving to the one staying.

Notice something odd? The phrase doesn’t thank anyone or say goodbye. It just acknowledges that someone worked. That’s exactly why it’s so useful, and exactly why it gets into trouble.

Where you’ll hear it (everywhere)

Live in Korea for a week and you’ll hear it more than your own name.

Leaving work. The classic. One person stands up, says it to the room, and the room says it back.

End of a meeting. The moment the last slide closes, someone says “자, 수고하셨습니다” (“Right, good work, everyone”), and chairs scrape back. In Korean meetings, this is effectively the gavel. Read the published minutes of a Korean local council meeting and you’ll see the committee chair say 수고하셨습니다 to department heads after their answers, over and over, like punctuation.

Taxi drivers. You pay, you open the door, and you say “수고하세요” or “감사합니다, 수고하세요.” The driver is going to keep driving all night; you’re acknowledging that.

Shops, cafés and convenience stores. Same logic. You grab your change at the convenience store at 1 a.m. and say “수고하세요” to the person on the night shift. It’s one of the kindest small things you can say in Korean, and it costs zero won.

After an exam. On the night of the 수능, the national university entrance exam, parents waiting at the school gates say “수고했어” to their kids before anything else. It means “it’s over, and I’m proud of you.” (More on that night in our suneung guide.)

After any shared effort. A moving day, a group project, even the end of a long online game raid, where someone types “수고하셨습니다~” before logging off and everyone answers “ㅅㄱ” (the initials, because typing four syllables after a two-hour boss fight is too much to ask).

And yes, if you text your mom that you finally finished a big project, there’s a good chance you’ll get back “수고했다 우리 딸/아들” followed by a flower emoji, a thumbs-up emoji and a photo of what she’s cooking for dinner.

The great hierarchy debate

Here’s where it gets spicy.

Ask a room of Korean office workers whether a junior can say 수고하셨습니다 to a senior, and you’ll get three answers: “Of course,” “Absolutely not,” and “I say 고생하셨습니다 instead, just to be safe.” Then they’ll argue until the coffee goes cold.

The “absolutely not” side has an official ally. The National Institute of Korean Language (국립국어원), which is the closest thing Korean has to a referee, published an etiquette guide called 표준 언어 예절 (“Standard Language Etiquette”). In its online Q&A, the institute repeatedly quotes that guide: expressions like 수고하다 and 고생하다 “can give the impression of evaluating the senior’s efforts,” so saying 수고하셨습니다 or 고생하셨습니다 to a senior is “not appropriate.”

The logic goes like this. Acknowledging someone’s effort implies you’re in a position to judge it. A teacher tells a student “수고했어.” A boss tells a team “수고했어요.” So when the intern turns to the CEO and says “수고하셨습니다,” it can sound, to a certain ear, like the intern is patting the CEO on the head. “Good job today, sir. Keep it up.”

On leaving work, the same guide (as quoted in another of the institute’s answers) is even more specific: young people often say “수고하십시오” to seniors on their way out “without thinking it is an inappropriate greeting,” but the listener “may be offended,” so it’s better not to. To peers and juniors, though, “먼저 갑니다. 수고하세요” (“I’m heading off. Keep up the good work”) is fine.

The “of course” side has a good argument too. Nobody saying 수고하셨습니다 at 6 p.m. is actually evaluating anything. It’s a ritual, the way “how are you” in English isn’t a medical inquiry. In August 2026, someone posted a formal request on the institute’s Q&A board asking it to change the guidance, arguing that 수고하셨습니다 is a light courtesy that thanks people for their work, and that anyone offended by it is, to paraphrase, being a bit petty. The post had been viewed more than 7,000 times when we checked. The institute replied that it would pass the suggestion on to the relevant department.

And the institute itself has softened its tone. In a 2025 answer about 수고하세요, it explained that the phrase has traditionally been considered undesirable towards seniors, but added that people’s perceptions change over time, and that some now argue it no longer reads as a judgment of the other person at all. Language etiquette, it noted in another answer, isn’t a fixed rule.

So who wins? Honestly: the room you’re in. Many younger managers won’t blink. Some older ones will notice and say nothing. A few will notice and say something, and that something might be the start of a 꼰대 lecture you didn’t sign up for. That’s why this is a nunchi question more than a grammar question.

Say / Mean: 수고하셨습니다 (su-go-ha-syeot-seum-ni-da) literally means “you have taken trouble.” What it means depends on the direction. Downwards or sideways: “Thanks, good work today.” Upwards, to some ears: “Good work today, I’ve reviewed your performance.” Same words, different elevator.

The 고생 workaround (which isn’t one, officially)

A lot of Koreans have been taught a neat fix: 수고 is for juniors, so say 고생하셨습니다 (go-saeng-ha-syeot-seum-ni-da) to seniors instead. One person on the institute’s Q&A board in September 2026 described exactly this, being “corrected” by colleagues from 수고 to 고생, and asked which was right.

The institute’s answer: neither. According to 표준 언어 예절, both 수고하셨습니다 and 고생하셨습니다 can sound like you’re evaluating a senior’s effort. The suggested alternative was 애 많이 쓰셨습니다 (“You put so much into it”).

So the “고생 is safer” rule is office folklore, not the official line. That said, the two words really do feel different:

수고 is effort. Work-shaped, everyday. You 수고 at your desk.
고생 (苦生, literally “bitter life”) is hardship. The dictionary defines it as “going through hard, exhausting things, or such a life.” You 고생 in the army, in a bad job, in a flood, during a three-hour delay at the airport.

Because 고생 sounds heavier, 고생하셨습니다 feels more sympathetic, closer to “you went through so much.” That’s why a lot of people feel it’s warmer, and why it’s the perfect response to someone’s army stories. But it also means it can be oddly dramatic. Say “고생하셨습니다” to your boss after a 20-minute meeting and you’re implying the meeting was a war.

And whatever you do, don’t say 고생하세요 (“please suffer”) to someone as you leave. 수고하세요 sounds like “keep up the good work.” 고생하세요 sounds like “enjoy your misery,” and one new employee on the institute’s Q&A board described it as feeling like you’re taunting the other person. Same politeness level, very different vibe.

What to say instead: the cheat sheet

If you’re the junior and you want zero risk, here is what the institute and most cautious Koreans suggest.

Situation	Say this	Romanization	What it does
Leaving before your boss	먼저 들어가 보겠습니다.	meon-jeo deu-reo-ga bo-get-seum-ni-da	“I’ll head off first.” The standard. Humble, no judging involved.
Same, slightly softer	먼저 가 보겠습니다. 내일 뵙겠습니다.	meon-jeo ga bo-get-seum-ni-da. nae-il boep-get-seum-ni-da	“I’ll go first. See you tomorrow.” Polite and forward-looking.
Leaving early, feeling guilty	죄송한데 먼저 들어가 보겠습니다.	joe-song-han-de…	“Sorry, but I’ll head off first.” Useful at 회식, too.
Your boss leaves before you	안녕히 가세요 / 들어가세요.	an-nyeong-hi ga-se-yo / deu-reo-ga-se-yo	“Go safely.” Simple and always correct.
Boss comes back from a hard meeting	애 많이 쓰셨습니다.	ae ma-ni sseu-syeot-seum-ni-da	“You put so much into that.” The institute’s pick.
Boss helped you with something	도와주셔서 감사합니다.	do-wa-ju-syeo-seo gam-sa-ham-ni-da	“Thank you for helping.” Specific thanks beats generic praise.
To peers, juniors, the taxi driver, the cashier	수고하셨습니다 / 수고하세요	su-go-ha-syeot-seum-ni-da / su-go-ha-se-yo	Go for it. This is what it’s for.

Skip “먼저 실례하겠습니다” (“Excuse me for leaving first”): the guide quoted by the institute says that although many people don’t mind it, it doesn’t fit Korean sensibilities and is better avoided.

Why it matters so much: the ritual of leaving

To understand why one sentence gets so much attention, you have to understand that leaving a Korean office is a small social event.

For decades, a lot of Korean workplaces had an unspoken rule: you don’t leave before your boss. People would finish their work at six and then perform being busy until seven, opening and closing the same spreadsheet like it owed them money. Things have changed a lot, and plenty of younger Koreans now leave on time without a second thought. But the moment of standing up still carries some weight. You’re breaking from the group, and the phrase you say is how you do it gracefully.

That’s the deeper job of 수고하셨습니다. It’s not really about work. It’s about saying “we were in this together today, and I saw that you were here too.” It’s a tiny dose of 정 (jeong), the sticky bond that grows from shared time. The phrase is the door you close softly instead of slamming.

It’s also why the direction matters. In a culture where age and rank shape how people talk, who gets to acknowledge whose effort is part of the structure. When the arrow points the other way, some people feel the floor tilt a little, even if they couldn’t explain why.

Why English has no match

Try translating 수고하셨습니다 for an English-speaking coworker, and you’ll go through the five stages of grief.

“Good job”? Too evaluative. That’s precisely the thing the etiquette guide is worried about. And you’d never say “good job” to a taxi driver.
“Thanks for your hard work”? Closer, but stiff. It sounds like the last line of a corporate email, and nobody shouts it across an open-plan office at 6 p.m.
“Good work today”? Decent for a manager talking to a team. Weird from an intern to a director.
“Have a good one”? Works for the cashier version (수고하세요), but loses the whole “I see your effort” part.
“Otsukaresama”? If you’ve worked in Japan, お疲れ様です does a very similar job. English never landed on “acknowledge the effort” as a goodbye, possibly because English-speaking offices just quietly vanish at 5:01.

English splits this phrase into several jobs (thanking, praising, saying goodbye) and makes you pick. Korean bundles them and lets the situation decide.

Its cousins: 잘 부탁드립니다 and “have you eaten?”

수고하셨습니다 has a matching bookend. At the start of things, Koreans say 잘 부탁드립니다 (jal bu-tak-deu-rim-ni-da), literally “I ask you to treat me well.” You say it on your first day, at the start of a project, when you meet your partner’s parents. If 잘 부탁드립니다 opens the relationship, 수고하셨습니다 closes each day of it. A Korean working life is basically thousands of 수고하셨습니다 between one 잘 부탁드립니다 and the farewell party.

The other cousin is 식사하셨어요? (“Have you eaten?”), which isn’t a question about food any more than 수고하셨습니다 is a performance review. Both are care disguised as routine. We wrote about that one here.

How to use it without stress

Say something when you leave. Silence is the only real mistake. Any polite closer beats sneaking out.
To peers and juniors: 수고하셨습니다, freely. It’s warm, natural and expected.
To your boss: 먼저 들어가 보겠습니다 or 내일 뵙겠습니다. Zero risk. Then listen to what your colleagues say. If the whole team says 수고하셨습니다 to the team leader and the team leader smiles, you’ve learned your office’s dialect.
To service workers: 수고하세요. Taxi drivers, night-shift cashiers, the person who fixed your boiler. Use it generously.
Don’t “fix” other people. If a Korean colleague says 수고하셨습니다 to a senior, don’t correct them with the National Institute of Korean Language. Nobody likes the intern who cites official guidance at 6 p.m.
Never say 고생하세요 as a goodbye. Unless you’re in a drama and about to be slapped with a glass of water.

And if your boss says “수고했어요” to you on the way out, the right answer is simple: smile, bow a little, and say “들어가세요” (“Get home safe”). You’ve both done your part. The day is officially over. 수고하셨습니다, everyone.
