Abstract
Purpose: This study was done to investigate the mediating effect of trust in supervisor in the relationship between ethical leadership of nursing unit managers and job embeddedness of staff nurses.

Methods: Participants were 216 staff nurses from one tertiary general hospital and three general hospitals. Data were collected from June to August, 2018, using self-report questionnaires. Data were analyzed using descriptive statistics, independent t-test, Mann-whitney U test, One-way ANOVA, Kruskal-wallis, Welch test, Scheffe?test, Games-Howell, Pearson correlation coefficients and multiple regression, with the SPSS/WIN 23.0 program. A mediation analysis was performed according to the Baron and Kenny method and Sobel test.

Results: There were significant relationships between ethical leadership and trust in supervisor (r=.85, p<.001), ethical leadership and job embeddedness (r=.38, p<.001), and trust in supervisor and job embeddedness (r=.41, p<.001). Trust in supervisor showed full-mediating effects in the relationship between ethical leadership and job embeddedness.
Conclusion: The results of this research show the importance of the role of trust in the supervisor as a full mediating variable. To increase the nurses¡¯ job embeddedness, it is necessary to develop programs and strategies to enhance trust in supervisors, as well as training nursing unit managers to provide ethical leadership.
