A Korean coworker's parent just passed away and I've been told about the funeral?

Korean funerals are typically held over three days at a hospital funeral hall (장례식장), and your attendance even briefly is deeply appreciated. Wear a black suit with a white shirt and black tie for men, or a modest black dress or suit for women. Avoid bright colors, loud accessories, or anything flashy. White or muted tones are also acceptable if black isn't possible.

At the entrance you'll sign the guestbook (방명록) and present a condolence envelope (부의금) with cash inside, typically 50,000 to 100,000 won for a coworker's parent. Use a clean white envelope with 부의 (condolence) or 賻儀 written on the front and your name on the back. Inside the memorial room, bow twice deeply to the portrait of the deceased, then once to the grieving family without saying anything. The phrase 삼가 고인의 명복을 빕니다 (I sincerely pray for the peace of the departed) is appropriate but a quiet bow alone is fine. The family will offer you a meal of yukgaejang and rice in the dining area afterward, and accepting it is part of paying respects. Stay 30 to 60 minutes is normal.
