The study was conducted on Yemeni public joint stock companies.

The study adopted a descriptive-analytical approach and used a questionnaire as the primary data collection instrument.

The study reached several findings, most notably the existence of a mediating role of administrative empowerment in the relationship between ethical leadership and job performance in the Yemeni public joint stock companies under study. This finding highlights the importance of administrative empowerment in strengthening the effect of ethical leadership on improving job performance.

The study recommended maintaining continuous attention to improving job performance in both quantity and quality, developing employees’ skills, and strengthening their perseverance by promoting ethical values and practices among the leaders of Yemeni public joint stock companies.
