Ethical leadership and organizational silence: a systematic review

Abstract

Purpose This study aims to comprehensively analyse and synthesize existing studies that investigate the relationship between ethical leadership and organizational silence. This review also aims to provide a detailed understanding of the impact of ethical leadership on various dimensions of organizational silence. Design/methodology/approach This study uses a systematic review methodology, adhering to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, to explore the relationship between ethical leadership and organizational silence. Using the SCOPUS database, the search involved Boolean operators to narrow down relevant papers published in English between 2000 and 2023. Following a meticulous screening process, 10 papers were selected for review after removing duplicates and excluding non-English or irrelevant studies. The selected papers underwent a methodological quality assessment, ensuring focused research questions, precise subject selection methods, representative samples and reliable measurement instruments. Findings This study has led to two crucial findings. Firstly, the review has revealed that employees feel secure and motivated to share their opinions when leaders are ethical, which is essential from the perspective of organizational performance. Secondly, in a collectivist culture, employees generally do not express their views (prosocial silence) even though the leaders are ethical. However, in an individualistic culture, employees express their views and opinions on organizational matters even though leaders are ethical. Research limitations/implications This research has three research implications. Firstly, the papers on the relationship between ethical leadership and organizational silence followed quantitative approach. Besides, there is a dearth of qualitative studies. Therefore, qualitative studies are urgently needed to understand the true nature of this relationship. Secondly, the relationship between ethical leadership and organizational silence in existing literature is inconsistent. Several studies have reported a non-significant relationship between these two constructs, which requires further investigation. Thirdly, most existing literature on the relationship between ethical leadership and organizational silence is concentrated in the manufacturing sector. Therefore, it is necessary to test this model, even in the services or other sectors. Originality/value To the best of the authors’ knowledge, this is the first study to have reviewed the impact of ethical leadership on organizational silence. This review provides insights into how ethical leadership can mitigate silent behaviour. In addition, this review suggests future research directions pertaining to the relationship between ethical leadership and organizational silence.
