The Sociolinguistic Journal of Korea 14(2). Working with others in organizations, people often need to express conflicting opinions. An argument is the process of harmonizing and compromising conflicting opinions. Many researchers have recognized the value of argument and conducted research on interpersonal argument, ranging from specialized contexts with special issues to more general conversational contexts. However, there has been relatively little research conducted on this important interpersonal communication aspect in Korea. This study examines the relationship between personal traits related to argument and personal success within organizations. Three personal traits - argumentativeness, argumentative flexibility, and verbal aggressiveness - were used to measure individual characteristics towards argument; and, the time spent for promotion, job satisfaction, and organizational commitment were used to assess organizational success. In addition, the present study attempted to discern if there is any difference in the participants' personal traits toward argument according to the group they belong to. The participants' background information such as the type of organization they work for, the type of work they currently do, gender, age, marital status was collected. The results of a survey administered to 202 office workers are discussed in light of implications.
