Background: Ethical leaders show their values through their positive green behavior, and setting an example is a chance for managers to deliver value to subordinates. Ethical leadership is believed to work as support factor making nurses reciprocate in shape of ethical response and productive voice. Aim of the study: Assess the relationship between ethical
leadership and nurses' voice behavior. Subjects and Methods; Design: A descriptive correlational design was used to conduct this study. Setting: The study was conducted at Zagazig University Hospitals. Subjects: Simple random sample was selected from nurses working at the above mentioned setting (n= 400). Tools of data collection: Two tools were
used to collect these data, Ethical Leadership questionnaire and Nurses' voice behavior Scale. Results: One third of the nurses perceived that their leaders have high ethical leadership at work. In terms of voice behavior, small percent (22.2%) of nurses exhibited high level. Moreover, there were highly statistically significant positive correlations between nurses' perception of ethical leadership and nurses' voice behavior where p value less than 0.05. Conclusion: There were highly statistically significant positive correlations between nurses' perception of ethical leadership and their voice behavior. Recommendations: Conducting training programs and workshops for all managerial levels to clarify the concept of ethical leadership, and the extent to which the hospital and staff benefit from ethical leadership. Develop workplace green teams and senior medical leaders could behave more open to nurses' voice and respond adequately.
