In this study, we examined some key elements of authentic leadership and how they can be magic bullets for peace in the workplace. Survey research design involving 208 employees in both public and private organizations were employed. Three (3) key elements of authentic leadership style were used namely, inspiring motivation, ethical transformational quality, and leadership transparency. Data obtained were analyzed by means of descriptive and inferential statistical tools. The research findings indicated that authentic leaders who possess ethical transformational abilities are better able to foster harmony in the workplace. Another strategy to enhance workplace harmony was to inspire motivation. We also looked at how service-oriented leadership improves harmony at work and finding indicated that leadership openness and a fair distribution of information both contribute to improved workplace harmony. Thus, the study concludes that genuine leaders use social exchange theory to improve workplace harmony, hence, authentic leadership serves as a determinant of industrial harmony. On the basis of the findings, to improve workplace harmony, the study recommends that managers in both public and private organizations need to cultivate authentic leadership styles via moral transformational traits, motivating inspiration and leadership transparency. By so doing, they can enhance workplace harmony, which will in turn contribute significantly to organizational success and growth.
