The purpose of this study was to add to the literature on the implications of relevant and trustworthy organizational communication practices on employee attitudes and thereby on overall organizational effectiveness.  As such, the linkages between employees’ perceptions of information source credibility and their in-role performance and job tensions particularly when such relationships are mediated by employees’ information justice perceptions and satisfaction with organizational communication were examined.  Relevant theories and the literature were explored to assess the study constructs, postulate the study hypotheses, and assimilate them into a conceptual latent variable model.  The constructs were operationalized using standard questionnaires.  Data were collected from 816 managerial-level executives working in different organizations all over  India.  The data were then subjected to various statistical analysis procedures including path and mediation analyses as per structural equation modeling techniques.  Based on the results of these analyses all the study hypotheses and the proposed conceptual latent variable model were empirically confirmed.  Accordingly, the theoretical and practical implications of the findings were documented.  The study concludes by noting its limitations and outlining scopes for future research..
