It is noted that employees tend to remain silent at work because they do not want to have risk of discontinuity of job due to voice up. This study has tried to understand the impact of dimensions of employee silence (Defensive silence, Acquiescent Silence and Pro-social silence) on employee commitment among faculty of higher education institutions in Sindh. A close ended questionnaire was used in the study and data was collected from 234 Faculty members determined on the basis of sample size table given by (Saunders et al. 2009) and same was analyzed through correlation analysis and regression analysis. Results of the study suggest that all three dimensions of employee silence (Defensive Silence, Acquiescent Silence and Pro-social Silence) negatively and significantly affect employee commitment among faculty members of higher education institutions in Sindh. The findings of the study recommend that management of the universities should work on silence related problems which are faced by employees to create a better environment. Results further elaborate that employee silence is a negative sign because the commitment level of the employees tend to be decreased if silence exists within the organization.
