Especially, foreigners must be mindful of these cultural elements in their daily routines in Korea. The paper also explores employee socialization practices in Korean organizations. The result of the paper showed that Korean organization mainly follows collective, formal, sequential, fixed, serial, and divestiture techniques of employee socialization. However, often Korean organizations use social activities as a means of employee socialization.
