Nursing personnel's organizational commitment is a growing global concern, influencing retention in dynamic and high-demand healthcare environments. Ethical leadership and organizational culture both contribute to organizational commitment. Little is known about these variables’ interaction when they coexist and if results vary according to nursing institutions’ sizes. This study investigated the impact of ethical leadership and organizational culture on nursing personnel's organizational commitment in Greece and examined whether the size of the organization modifies these results. A cross-sectional study conducted, enrolling 724 nursing personnel from two secondary (<300 beds) and two tertiary (>300 beds) Greek hospitals. There were used the Ethical Leadership Scale, the Organizational Culture Profile and the Three-Component Model of Commitment. Descriptive statistics, independent t-test, Spearman and Pearson correlation coefficient, multivariate and multivariate linear regression analyses were performed. The increase in ethical behavior was associated with all three dimensions of commitment.
