When you answer phone calls at work, Koreans usually say their work station/section and full name like “Chongmugwa-eui Kim Minwoo-imnida(입니다).” Then, if the caller is looking for your boss, you say “Bujang-nim(부장님)” or “Kim Bujang-nim(부장님),” as if you are directly addressing your boss. If the caller is looking for a worker below your position, you say the full name and the “ssi(씨)” (Kim Minwoo-ssi). If the caller asks for someone that you know personally, you can omit the last name
