정부의 공공부문 개입이 노동조합의 조직전략에 끼친 영향 -국민건강보험공단의 노조통합 합의결정을 중심으로-

This paper examines the reason why two unions in the NHIS(National Health Insurance Service) agree with union merger, what the power source for merger determination is, and what issues in dispute are. In concrete, this paper explores internal factors which two unions came to an agreement with merger determination. And analyzes the influence of the external factors-that is the government’s involvement strategy to public service organization-on two organizations. According to the results, the merger determination is attributed to the accumulated needs of the rank-and-the file. It is also founded that the knowing which the union density has got down rapidly from 2009 was the direct motive of the merger determination. Before union merger, there are a couple of problems to solve. One is the decision about an upper union, and the other is to relieve the dismissed employees and to secure their membership. In relation to industrial relation, the messages from this paper are three. First, every union should try to harmonize the need from bottom-up and the top-down governance. Second, over two unions in one company weaken the bargaining power of unions. Third, an union merger in circumstance of the firm-centered union system can strengthen the context. So we need to consider about that.
