Your boss at work
합쇼체 · 해요체
Reports, meetings and anything official to a superior go in the formal hapsyo style. In a relaxed chat by the coffee machine, haeyo is fine — but never banmal unless they clearly invite it.
Common mistakeAnswering a boss with a casual “알았어요” (got it). At work, “알겠습니다” (understood) is the expected reply.
