This article investigates the potential mediating role of work engagement/job burnout in the relationships of leader's verbal communication style and job satisfaction. Results suggest that autocratic verbal communication style leads to low job satisfaction. To the contrary, supportive verbal communication style results in high job satisfaction. Furthermore, work engagement plays an intermediating role between leader's verbal communication style and job satisfaction. Although job burnout plays a mediation role between autocratic verbal communication style and job satisfaction, the mechanism is non-existent between supportive verbal communication style and job satisfaction. The article revealed the significance of leader's verbal communication style, as well as the diversities, which affected job satisfaction and thus influenced job performance.
