Today, labor unions have become more serious and have more critical roles in the IT industry. Labor union should enhance the quality of working life in an organization. It is the most important role of the union to satisfy employees. When a labor union enriches its roles, members have a positive attitude to the union. Hence, workers will be more satisfied and make more positive results. Moreover, although members have positive attitudes to the union, when labor and capital have a negative relationship, workers do not make the best performance. Furthermore, although unions and the companies work in close cooperation, when members have a negative attitude to the labor union, workers' performance will also decline. Hence, a positive attitude to labor unions and union-management relations has a mutual benefit for performance. This study explains these relationships with the effect of attitudes to labor unions (satisfaction, trust, and commitment) on organizational commitment and organizational citizenship behavior, and the moderate effect of union- management cooperation. The purpose of this study is to suggest that labor unions should have a positive relationship with management and win members' recognition in the IT field.

This study reviews the trend of job separation rates for three years from 2002 to 2005 and investigates the various elements which influence this trend, especially the role of the labor unions, by using Korean Labor Panel data. In the basic statistics, the job retention rate of union members were higher by an average of 28.3% points compared to non-union members, but in the results of controlling the observed variables of individual influences in changing jobs, it was estimated that unions increase the job retention rate by 11% to 13% points. To investigate the effect of unions on the job stability of workers in detail, the non-linear decomposition method developed by Fairlie (2003) was used in the analysis. In examining the difference of job separation rates between union members and non-union members through observed variables of workers in explainable parts and unexplainable parts by using the non-linear decomposition technique, the contribution of the explainable part was estimated to be 67% to 74% and the unexplainable part accounted for the rest which was 26% to 33%. This suggests that not only does the union contribute to the job stability of its members, but the propensity to change jobs for a worker who is a union member is on average lower than that of a worker who is not a union member or who works at an establishment that does not have a union. The results of the empirical analysis show that the job stability effect of labor unions is limited within the boundary of a maximum 7% to 9% points. The reason for the effect of labor unions on job stability being so low is due to various reasons such as collective bargaining structure by company, intensified business competition after the financial crisis, and labor market segmentation.

This study analyzed the effects of labor unions on the wages of Korean female workers using 'Korean Labor and Income Panel Study.' In the estimation we considered the self-selection bias due to the women's labor force participation decision and a plausible non-response bias from not answering the question about the company size in terms of number of employees. By fixed effect estimation we found that labor unions in Korea do not increase the wages of both the female union workers and non-union workers who work at a company in which a union is organized comparing to female workers who work at company without a union. This results indicates that female workers who work in the company with labor union tend to have unobserved characteristics that are positively correlated with both wages and the probability to enter the company with labor union. We also came to the conclusion that there is no free-rider effects of non-union workers.

This paper attempts to verify that the economic gap between the workers in (large) firms with unions and those in (small and medium size) firms with no unions has recently been widened rapidly. A comparison of the wages of the workers belonging to the business establishments with and without trade union shows that the union premium has increased very sharply since 1997, after a relatively long periods with little changes. Also found is that union sector has witnessed a sharper decline in the share of the new entrants among workers as well as a faster increase of the average tenure of workers. These all indicate that the trade unions have forced a market equilibrium to move farther away from the competitive equilibrium in recent years.

Purpose - This study aims to examine whether key differences in characteristics of unions have significant implications for absenteeism. To uncover what characteristics of union made workers make decisions to be absent, this study used such key dimensions of unionism as democracy, cooperative strategy of a union, and d density rate. Research design and methodology - The research model of this study is that absenteeism has positive relations with union's democracy and density. But it has negative relations with union cooperative strategy. This study was conducted by survey method on 333local unionized business entities of metal industry in South Korea. Results - The result shows that significant and positive relationship between unions with high density rates, democracy and absenteeism which is in line with the argument of the previous studies. Different from the expectation, the hypotheses 2, it has been shown that there is positive relation between cooperative strategy of union and the decision of workers to be absent. Conclusions - Employers with unions with high density rates could not fully exercise disciplinary power against those workers absent at workplace since a strong union shields them effectively from punishments by employers.

This paper examines the relationship between diversification and financial performance of community credit unions in Korea from 2011 to 2017. To do so, I employ fixed-effects panel analyses using credit union level panel data collected from the National Credit Union Federation of Korea. This study finds evidence that business diversification is likely to lower the ratio of troubled loans, which means improving asset quality of credit unions. However, the relationship between diversification and asset quality is not linear but nonlinear, which means over-diversification would have negative effects on asset quality. Next, diversification tends to increase profitability. Specifically, although diversification results in a rise in expenditures, an increase in profits made by diversification outweighs the rise in expenditures, which contributes to profitability. Put together, diversification would be a good business strategy to improve both profitability and asset quality. Given a result that fast loan growth deteriorates asset quality, credit unions' managers might adopt the diversification strategy to enhance asset quality, and not to pursue their own objectives motivated by moral hazards.

Purpose: We compared the time how much time spent until the bone unions, when we grafted fresh frozen allograft during therapy of benign bone tumor depends on the degrees of bony unions. Materials and Methods: This study selected 29 cases, in which a curettage on the benign bone tumors was conducted and a fresh frozen allograft was transplanted. The area of the focus, the new bone formation, the recurrence of the focus and complications in the plain radiographs were observed. Results: The average time when we could find out bony unions in the radiographs is eleven weeks. The time when we could observe the unions in the radiographs are 11.4 weeks in allograft group, 10.7 weeks in allograft and autograft groups and 13.6 weeks in allograft and bone substitute. On radiologic findings, the average lesion size is 40 cm3. The time when we could find bony unions are 9.3 weeks in less than 40 $cm^3$ and 12.9 weeks in more than 40 $cm^3$. We could observe recurrences in two cases. Conclusion: The authors could get the similar results between fresh frozen allograft, allograft and autograft after curettage of benign bone tumor. We can think the ideal method which is the transplantation of autograft, but if we can’t get autograft enough, the best way which heal the defects is the transplantation of fresh frozen allograft.

This paper proposes to examine the relationship between the two trade unions of Hyundai Motor Company (HMC) - those of the regular workers and of the in-house subcontract workers - around the issue of converting irregular workers to regular ones, which has been a social issue for a long time, and, furthermore, to find a desirable solution. The politics of the in-house subcontracting rotate around three axes: the conflictive collusion between the company and the regular workers'union regarding the internal labor market; the exclusion and resistance between the company and the subcontract workers'union; and the solidaristic conflict relationship between the two unions. After the final decree by the supreme court in 2012 the conflict and collusion/solidarity relationship of the three social actors have been amplified in scale - the continuous limping of the special bargaining between the company and the unions, the intensified conflict between the company and the subcontract workers'union, and the crisis of the collusion between the branches of the two unions are all evidence of this. A clue to the solution to the issues of in-house subcontracting in HMC can be found through reestablishment of the relationship among the three actors. In order to solve the in-house subcontracting issues in HMC, phased and lawful switching from irregular to regular positions, improvement of working conditions for the irregular workers, integration of the two unions (realization of 'one company one union'), and negotiated flexibility in the internal labor market will be required. Also to be considered are installation of a special committee for the issue, and utilization of external consultants. The result would be the possibility for the corporate labor market of HMC to be composed of regular workers, legal contract workers and directly-employed contract workers, which could be realized through bilateral relations of 'the labor and management conflict partnership'.

As the number of precariats grows, their poor labor rights and working conditions are becoming issues of major concern all over the world but how to represent their interests is still controversial. Basically, the union is the institutional mechanism for representing the labor rights. However, it is difficult for workplaceand enterprise-based unions to fully represent the labor rights of precarious workers. Recently, so-called community unions have emerged in the United States, the United Kingdom, and Japan as independent organizations representing the rights of non-standard workers. Community unions refer to labor unions which organize precarious workers across firms at the regional level. They are known to be suitable for covering the unemployed, job seekers, indirect employment workers, short-term contract workers, and small-firm workers. In South Korea, since the financial crisis in 1997, a dramatic increase in the number of precariats leads to emergence of new types of trade unions such as the Youth Community Union, the Arbeit Workers' Union, the Artist Social Union and the Korea Musician's Union. They have engaged in various activities to guarantee the labor rights of precariats. Recently, researchers have also tried to identify defining characteristics of these new forms of unionism. To expand research on trade unionism in South Korea, this study compares two different types of community unions: the Youth Community Union and the Arbeit Workers' Union. We believe that this attempt can contribute to the research on the alternative labor movement. For this purpose, this study starts with theoretical discussions on community unions, and compares the Youth Community Union with the Arbeit Workers' Union based on the five characteristics of community unionism: membership and organization structure, the recognition struggle, the type or scope of interest, solidarity with other civic organizations, and the repertoire of resistance strategies. Based on this comparative analysis, this study seeks to foresee the possibility of how community unionism will develop in South Korean in the future.
