Recently, the government has implemented a new public management policy to improve the performance of the public sector, and the government intends to strengthen the public organization, such as the private sector, by strengthening the competition and focusing on performance. As a result of adopting and applying the personnel management system of the private enterprise to the public institution, the workers of the public institution became more immersed in the labor union to cope with the job insecurity and change. At this time, the employee is simultaneously given the role of the organization member and the role of the union member. It is called dual commitment in which workers are immersed simultaneously in the two organizations, the company and the union, without a conflict of roles. In order to confirm the dual commitment, this study identify the relationships among union instrumentality, organizational commitment, union commitment, and organizational citizenship behavior of public employees which have relatively higher union participation rates than private companies. To test the hypothesis, the questionnaires were distributed to 815 employees of 10 public institution under the Ministry of Employment and Labor, and analyzed 429 participants excluding the unsatisfactory response. The hierarchical regression method was used for this analysis. The results of this study, it was found that organizational commitment has found the mediating effect between union instrumentality and organizational citizenship behavior. And it was found that union commitment is a mediator between union instrumentality and organizational citizenship behavior. Workers have identified dual commitment that both their roles as organizational members and their role as trade union members are at the same time immersed without conflict. This study has empirically tested the effect of union instrumentality on the public institution employees in confirming dual commitment, and provides practical implications. And it is found that organizational commitment and union commitment have an effect on organizational citizenship behaviors. In addition, it discussed limitations and further research directions. As a result of limited research conducted by agencies under the Ministry of Employment and Labor, whole public institution can not be generalized. In the future research, it is necessary to collect data by type of public institution, and comparative analysis with private institutions is also needed.
