Work Chats Stay Formal
Even a short, informal-looking KakaoTalk message to a manager or senior colleague should use polite sentence endings. Skipping formality in a work chat — even by accident — can come across as careless or disrespectful, more so than a similar slip in spoken conversation.
Casual Texting With Friends
With close friends, texts often drop full sentence endings entirely, relying on shorter fragments, particles, and slang. This casual register (반말) should generally only be used once both people have agreed to speak informally, or with people clearly younger or the same age as you.
Group Chats With Mixed Seniority
Company or team group chats often include people of different ranks, which means the whole chat usually stays polite by default, even among coworkers who are casual one-on-one. It’s common to switch briefly to more formal language whenever a senior person is active in the conversation.
Frequently Asked Questions
Should you text your boss formally in Korean?
Yes. Polite 존대말 is expected even in short KakaoTalk messages to a manager or senior colleague, the same as in spoken conversation.
Can you use banmal (casual speech) in a work group chat?
Generally not by default, especially if people of different seniority are in the chat — most work group chats stay polite unless everyone has explicitly agreed otherwise.
Is it okay to text a boss the same way you’d text a friend?
No — dropping formality in a message to a boss, even accidentally, can come across as careless. It’s safer to keep work texts consistently formal.
How do you know when it’s okay to switch to casual texting with someone?
It’s common and polite to explicitly ask, e.g. 말 놓아도 돼? (“can we speak informally?”), rather than assuming.
Register matters as much as vocabulary
Knowing which words to use is only half of Korean — knowing when to use them is the other half. Build both together.
