Scholars have largely focused on the negative consequences of organisational politics for employees’ performance. In contrast, we maintain that organisational politics has positive aspects and moderates the relationship between employee engagement and behaviors at work such as knowledge sharing, creativity, proactivity, and adaptivity. Using data from 253 high‐tech employees and their supervisors in Israel, our findings demonstrate that perceptions of organisational politics strengthen the relationship between employee engagement and these behaviors. When engaged employees perceive their workplace to be political, they are more proactive, creative, and adaptive, and more likely to share their knowledge with their peers. These findings confirm the challenge/opportunity stressor theory regarding perceptions of organisational politics and suggest that whether politics is viewed as positive or negative depends on the employees’ point of view. For those who are engaged and more actively involved in their jobs, politics can be regarded as a challenge and even an opportunity for obtaining more resources to improve their performance. Implications for the development of theory and practice in this area are discussed.
