The purpose of this study was to identify conflicts in the workplace of care workers working at the facility and to examine their effects on job exhaustion. The main results and implications are as follows. First, conflicts in the workplace experienced by nursing care workers were higher in case of work experience and higher in institutional facilities. In the case of nursing home care workers, the improvement of treatment such as salary increase according to work experience and increase in job position is not done. As the work experience is longer, expectation for improvement of treatment is more and more, but this is not satisfied and it seems that job satisfaction decreases and conflict in the workplace also increases. Second, the long-term care workers and the large scale of the facility showed that they experienced much exhaustion. Care workers are expected to change their roles in the workplace as their career progresses, but they feel that they feel exhausted as this is not done. Third, conflict in the workplace has a positive effect on the exhaustion of care workers. Particularly, conflicts in the workplace were influenced by role conflicts and communication conflicts. A care workers experience exhaustion if he or she does not have an appropriate role in the workplace or if communication difficulties occur.
