Ambidexterity at the manager level focuses on the crucial, but underexplored, role of managers’ knowledge, skills, and behaviors to address competing demands and promote organizational ambidexterity. As such, to successfully complete their assigned duties, managers need to employ the appropriate interpersonal style and calibrate their behavior to different contextual demands. This study highlights the role of the individual in the ambidexterity process by introducing the concept of influence tactic ambidexterity, to denote the frequent use of both hard and soft influence and investigating its role on task performance. Drawing on the literature on ambidexterity and HRM, we analyze data from a sample of 172 middle managers and their corresponding 68 supervisors working for multinational organizations, and provide evidence that influence tactic ambidexterity relates to higher levels and less variation in managers’ task performance compared to the sole use of either hard or soft tactics. Our findings also show that political skill positively moderates the relationship between influence tactic ambidexterity and a manager’s task performance. Therefore, this study suggests that influence tactic ambidexterity and political skill can be considered valuable HR assets for managers.
