This study starts from a thought about the negative impact of workaholism, one of the behavioral addiction symptoms that usually appear to office workers in Korea. To solve the following three research questions: first, what psychopathological problems are caused by office worker''s workaholism? Second, what impact relation will job burnout, among the psychopathological problems of office workers have with non-task behavior? Third, what impact relation will workaholism, office worker''s behavioral addiction have with non-task behavior and can the relationship between OCB and CWB be explanatory?, empirical study is conducted. As subject of research, salespersons are selected among the domestic office workers. 500 questionnaires are distributed and then 422 questionnaires are only collected. As statistical analysis, SPSS 20.0 is used to analyze the demographic characteristics and AMOS 18.0 is used to verify the structure model. As a result, first, after hypothesis testing on job burnout problems caused by workaholism in salespersons selected as a sample, it is found that workaholism has a statistically significant positive impact on job burnout. Second, after studying the relationship between the job burnout problems that salespersons are suffering from and the non-task behavior, an individual''s discretionary behavior, it is found that job burnout has a statistically significant impact on organizational citizenship behavior, a positive behavior and counterproductive behavior, a negative behavior. Third, the workaholism of salespersons did not have a significant impact on organizational citizenship behavior, but increased counterproductive behavior. Finally, job burnout mediated the relationship between workaholism and non-task behavioral variables. This study suggests the theoretical and managerial implications of this result discussion, limitations of this study, and future directions.
