Analyzing the Effect of Organizational Silence on Group Work Effectiveness with the Mediating Role of Organizational Identity Case Study: Isfahan Municipality

The purpose of this study is to explore the effect of organizational silence on group work effectiveness with the mediating role of organizational identity. The statistical population included 2013 employees of Isfahan Municipality. The sample size was determined equal to 323 via two-phase sampling as well as cluster sampling and proportional stratified sampling by means of Cochran formula. The data was collected through standard questionnaires of Wakola and Boradas' organizational silence (2005), Robbins' (2007) group work effectiveness and Cheney's (1983) organizational identity. Validity of the questionnaires was confirmed via content validity and reliability was obtained through Cronbach's alpha. Data analysis and testing of hypotheses were carried out using structural equation modeling (SEM) and Spss 24 and Amos 24 software. The results revealed that organizational silence has a significant negative effect on group work effectiveness with path coefficient equal to -0.39 and it has a significant negative effect on group work effectiveness with the mediating role of organizational identity with a path coefficient equal to -0.457. Also, based on the results of the secondary hypotheses, organizational silence is effective on dimensions of group work effectiveness including contextual factors, group composition, job design, and process variables with path coefficients of -0.38, -0.47, -0.49 and -0.55 respectively.
