본 연구의 목적은 팀 내 개인이 다른 사람과 차이나는 정도 즉, 개인간 인구통계학적 비유사성(demographic dissimilarity) 혹은 관계적 인구통계(relational demography)가 개인의 성과에 미치는 영향을 알아보기 위한 것이다. 자기범주화 관점(self-categorization perspective)과 유사성/매력 관점(similarity/attraction perspective) 및 정보/의사결정관점(information/decision-making perspective)을 바탕으로, 인구통계학적 특성 중 연령, 성별, 직급, 그리고 근속년수의 네 가지 측면에서 팀 내 구성원들 간의 관계적 인구통계를 분석하였고, 이들과 성과와의 관계를 비교분석하였다. 분석결과, 성별 비유사성 및 근속년수 비유사성과 개인성과 간의 관계는 약한 역 U자형 형태, 비선형관계를 보이는 것으로 나타났다. 이는 최근 다양성(diversity) 연구에서 성과와의 비선형관계를 제시하는 연구들과 일치되는 결과이다. 이로써 개인성과에 긍정적인 영향을 주는 적정 수준의 다양성 또는 비유사성이 존재한다는 사실을 알 수 있으며, 이는 성과관리의 책임을 지고 있는 관리자들에게도 중요한 시사점을 제시한다. Organizations are increasingly adopting work group arrangements such as cross-functional project teams that incorporate differences in functional or educational background (van Knippenberg & Schippers, 2007). Diversity is also introduced into work groups by mergers, acquisitions and joint ventures. As a result, managing diversity forms a major challenge for organizations. In this context, considerable research has focused on the distribution of demographic characteristics within work groups, and the consequences that arise (e.g., Chatman et al., 1998). Although diversity is a group characteristic, there is a stream of research on what is called relational demography (Chattopadgyay et al., 2004; Tsui & O’Reilly, 1989), which focuses on the effects of individuals’ similarity to their work group (e.g., Chatman & Flynn, 2001; Chattopadhyay, 1999) or to their leader (e.g., Tsui et al., 2002) as predictors of individual outcomes (van Knippenberg & Schippers, 2007). A recent development in this research is based largely on two related theories: what has been termed social identity theory (Tajfel & Turner, 1986) and self-categorization theory (Turner, 1987). The key questions in diversity or relational demography research are how similarities or differences between work group members affect individual outcomes or group processes and performance (e.g., van Knippenberg & Schippers, 2007). In this vein, our study explores how the relational demography in work teams can affect individual performance. In contrast to the social categorization perspective, the information/decision-making perspective emphasizes the positive effects of work group diversity. To integrate these opposing perspectives, van Knippenberg et al.(2001) propose the Categorization-Elaboration Model (CEM). This model posits that social category diversity may have a positive effect on task performance, because idea that the effects of relational demography might be curvilinear. The potentially positive effects of the relational demography on individual performance may only apply at a certain level, beyond which the lack of a common frame of reference may obstruct or prevent a full appreciation of all group members’ contributions. Thus, the following hypotheses were made: H1 : Demographic dissimilarity (Relational demography in work group) will have an inverted U-shaped curvilinear relationship to individual performance. H1a : Age dissimilarity will have an inverted U-shaped curvilinear relationship to individual performance. H1b : Gender dissimilarity will have an inverted U-shaped curvilinear relationship to individual performance. H1c : Rank (hierarchical status) dissimilarity will have an inverted U-shaped curvilinear relationship to individual performance. H1d : Tenure dissimilarity will have an inverted U-shaped curvilinear relationship to individual performance. We collected data from a private-sector firm. Participants comprised 130 employees from an electronic company located in Seoul. Relational demography and performance data were collected from the personnel records and documents of the company. We used performance appraisal ratings from supervisors and executives. The results of this study indicate that demographic dissimilarity (relational demography in work group) will have an inverted U-shaped curvilinear relationship to individual performance. The results provided support for Hypothesis 1b and Hypothesis 1d. However, the results did not support Hypothesis 1a and Hypothesis 1c. As noted above, the current study explored the curvilinear effects of relational demography on individual performance. The lack of significant curvilinear effects for age and rank dissimilarity might be explained by the organizational context in which these relational differences are embedded. The workforce at this firm had a high proportion of men (85%). Previous research has shown that the salience of demographic attributes as social categori

본 연구의 목적은 인지된 개인-환경 적합성이 조직시민행동과 개인성과에 미치는 영향을 알아보기 위한 것이다. 먼저 적합성은 대상에 따라 개인-조직 적합성, 개인-상사 적합성, 개인-동료 적합성의 세 가지 유형으로 구분하고, 각 유형별로 조직시민행동 및 성과와의 관계를 비교분석하였다. 다음으로 ASA이론(Attraction-Selection-Attrition theory), 유사성-매력이론(similarity-attraction theory), 사회정체성이론(social identity theory) 및 사회교환이론(social exchange theory)을 바탕으로 적합성과 조직시민행동, 그리고 적합성과 성과와의 관계에 미치는 공정성 지각의 매개효과를 검증하였다. 실증연구 결과, 개인-조직 적합성, 개인-상사 적합성, 개인-동료 적합성이 조직시민행동에 미치는 영향은 모두 정(+)의 관계를 보여주었다. 적합성과 성과와의 관계에 있어서는 개인-상사 적합성만이 통계적으로 유의한 정(+)의 관계를 나타냈다. 공정성 지각의 매개효과는 적합성 중 개인-상사 적합성과 조직시민행동 간의 관계에서만 나타났다. 이로써 적합성은 조직시민행동이나 성과에 직접적인 영향을 미치기도 하지만, 공정성 지각을 통해 간접적으로도 영향을 미침을 알 수 있다. 본 연구는 적합성을 대상에 따라 세 가지 유형으로 이론에 근거하여 분류하고 실증적 검증을 동시에 실시하였다는 의의를 가지고 있다. 이러한 세 가지 유형의 적합성은 서로 다른 결과변수를 예측하였으며 개인의 태도변수가 아닌 행위적 성과로서 조직시민행동과 상사가 평가하는 성과와의 관계를 고찰하였다는 점에서 기존 연구를 확장하였다. 또한, 적합성이 개인의 결과변수에 미치는 영향관계에 있어 공정성의 매개효과를 설정하였으며 이중 개인-상사 적합성과 조직시민행동과의 관계가 유의하였음을 알아냈다. 비록 모든 결과변수와 유의하지는 않았지만 이전부터 제기되어온 적합성과 개인수준 결과변수 간의 관계에 있어서 매개변수의 개입 가능성을 예측할 수 있다는 의의를 가지고 있다. There has been a large body of literature on the issue of person-environment (P-E) fit. To date, the majority of studies about P-E fit have focused on the effect of P-E fit on various work outcomes (e.g., Kristof, 1996; Kristof-Brown et al., 2005). Research on P-E fit generally supports the idea that a high level of P-E fit is related to a number of positive individual and organizational outcomes. P-E fit theory, by and large, states that workers who feel fitted to the organization will show higher level individual outcomes such as higher job satisfaction and organizational commitment because they share values, personality or goals with others (Bretz & Judge, 1994; O"Reilly, Chatman, & Caldwell, 1991). In social-psychological theories, similarity between people is predicted to lead to attraction (Byrne, 1971). The theories on attitudinal similarity explain why fit is posited to relate to favorable attitudes. That is, people find it more desirable to interact with others who have similar psychological attributes in that the interaction reinforces their own beliefs, behaviors and affect (e.g., Swan, Stein-Seroussi, & Giesler, 1992). Although prolific studies have been conducted to explore the effects of fit on the attitudes and behavior of employees, much of these studies have focused on only one or a few types of fit. But it should be noted that different types of fit tend to be related to job satisfaction, organizational commitment and intent to quit to a varying degree (e.g., Lauver & Kristof-Brown, 2001). For example, the environment in P-E fit has been typically focused on organization, supervisor, group and so on. However, researchers (e.g., Salancik & Pfeffer, 1978; Scott & Bruce, 1994) have paid attention to the role of coworkers as well as supervisors as the social environment that influences workers’ attitudes and behaviors since the workers spend more time and interact more frequently with their coworkers than with their supervisors. The coworkers are likely to be supportive when individual workers face difficulties with the supervisors. Therefore, the person-coworker fit (P-C fit) appears to be very important in shaping the worker’s perception and behaviors at work. In this vein, more research is needed to explore the varying relationships between a broader set of fit indices and the employee’s attitudes and behavior. Thus, the present study is designed to overcome this limitation by examining and extending relationships between multiple types of fit and employee attitudes. The purpose of this article is threefold: First, this study specifically focuses on the relationship between subordinates’, supervisors’, coworkers’ fit in terms of values, personality, goals and work-related outcomes. Going beyond organizational orientation, fit could be directed toward a variety of foci such as supervisors, co-workers, and work team or groups. A second and related issue pertains to the notion the relationship between fit and the organizational citizenship behavior (OCB) and performance ratings. The great interest in OCB appears to stem largely from the belief that these behaviors enhance organizational effectiveness (Podsakoff & MacKenzie, 1997), although comparatively little empirical research has been done to substantiate this belief. For example, little research has been conducted to substantiate its predictors such as the various types of fit. Thus, the second aim of this study is to address this question: Can P-O fit, P-S fit, P-C fit affects OCB and performance ratings? To address this question, we tested the effects of P-O fit, P-S fit, P-C fit on the relationship between OCB and performance ratings. Third, we clarify the mediating role of organizational justice in the relationship between perceived fit and OCB/performance ratings. On the basis of attraction-selection-attrition (ASA) theory, social exch
