Background and Objective:Organizational silence,faculty members' passive presence and their reluctance to interfere in public affairs is a common phenomenon in universities and higher education institutions that seemsto be influenced by several factors including ethical climate. Thus the goal of this research was to study the relationship between ethical climate withorganizational silence among faculty members.

Materials and Methods:Research method was descriptive-correlational and the data was collected through a survey. A sample of 183 faculty members were randomly selected out of the population of all faculty members of University of Sistana and Baluchestan. Research instruments included standard questionnaires ethical climate andorganizational silence. To analyze the obtained data, Pearson correlation coefficient and simultaneous regression analysis were used via SPSS₂₁.

Results: The mean scores were: caring climate (3.99± 0.71), rules climate (3.65± 0.91) law and code climate (3.98± 0.62), instrumental climate (3.14± 1.08), independence climate (4.31± 0.48), organizational silence (3.19± 0.33) was. The correlation coefficients between ethical climate and its components: caring, rules, law and code, instrumental and independence with organizational silence were respectively -0.565, -0.334, -0.424, -0.516, 0.39 and -0.505. The results of multiple regression analysis revealed that ethical climate can predict %40.1 of the variance organizational silence. Among the ethical climates: independence climate with β (-0.268), instrumental climate with β (0.266), law and code climate with β (-0.243) and caring climate with β (-0.14) predicted organizational silence.

Conclusion: Organizational silence of faculty members can be influenced by ethical climateso that caring, rules, law and code, independence climates reducefaculty members' organizational silence and authority, but instrumental climate  increases it.
