Journal Article 2013 11 07 There is an inherently political activity in all transactions, therefore, it is considered as one of the constituent elements of the organizations and has attracted the attention of management researchers. Although political behavior can have positive or negative consequences, much of the research focuses its dark side. This type of behavior creates a divisive and damaging work environment that threat overall organizational efficiency and effectiveness, and has an increasingly negative impact on employees. So awareness of creating factors plays an important role in preventing and limiting such behavior. In this regard, the present study was done to explain the predictors of political behavior by using cortical (quota) sampling. To collect data the standardized questionnaires were used. Questionnaire’s validity was confirmed by content and construct validity and its reliability were measured by Cronbach's alpha coefficients for each of the variables. For the analysis of research data by Structural equation modeling and path analysis Lisrel and SmartPLS was used.

Meanwhile human capitals are very important in chain stores. Previous studies implied that job performance (JP) was derived by constructs such as organizational citizenship behaviors (OCB) and organizational justice (OJ). So this research tries to investigate OJ on OCB and consequently on JP. So in this research we are tried to investigate the role of OCB on mentioned variables. Hypothesis of research is assessed by indigenous questionnaires approaches. The method of research was casual (Partial Least Square). To assessing mentioned hypotheses, 124 questionnaires distributed among employees of one of chain stores located in Tehran by systematic sampling methods. Results reveal that the construct of justices (expect distributed justice), OCB and job performance are in satisfying level. In addition there’s no evidence to reject casual hypotheses (impact of justice on OCB and consequently job performance) in 95% confidence interval. Finally to improving OCB and OJ‘s contributors some offers proposed. Nowadays employees have unique role in achieving goals and gaining competitive advantages in service oriented organizations.

In order to perform empirical analyses, measurements on the OCBs constructs based on the five dimensions of organizational citizenship behavior: altruism, conscientiousness, courtesy, civic virtue, and sportsmanship were developed, and the research model including the relationships between the OCBs constructs and information systems success variables of information quality, work efficiency, and IT innovation was proposed and empirically analyzed using structural equation modeling. Data collection instrument is questionnaire. Sampling method is available method. The results of structural equations modeling confirm model fitness in studied population. The contribution of this study is to provide strategic insights for successfully managing information systems by identifying the effects of organizational citizenship behaviors in information systems context.
