Studies have shown that voice could be utilized as an effective method to improve organizational effectiveness. This study explores the relationship between ethical leadership and employee voice behavior by focusing on the mediating role of the error management climate and the moderating role of the employee's organizational commitment. Analysis of data collected in three phases in China indicates that the error management climate partly mediates the relationship between ethical leadership and voice behavior. Also, organizational commitment is found to moderate the relationship between the error management climate and voice behavior. Theoretical and practical implications of these results are discussed.
