This research investigates abusive supervision’s impact on employee voice behavior. We hypothesize that abusive supervision will influence employee voice behavior through undermining employee’s perception of psychological safety. The study examines psychological safety’s mediating effect in the relationship between abusive supervision and employee voice behavior. We also hypothesize that uncertainty avoidance moderates the relationship between abusive supervision and psychological safety perception in that an employee with higher uncertainty avoidance feels more psychological unsafe when being abused by his or her supervisor. Regression analyses on the data collected from 258 employees and 102 supervisors working in two petroleum and chemical enterprises support the above hypotheses.
