IResponding to calls for a deeper exploration of the positive aspects of workplace intrusions under specific conditions, this study adopts the Job Demand-Resources model to investigate how work-related intrusions can positively influence task performance and innovative behavior through the mediating role of a key job resource: information sharing. While prior research has predominantly emphasized the negative effects of workplace intrusions, this study shifts focus to their potential benefits. Additionally, the moderating role of psychological capital in the relationships between information sharing, task performance, and innovative behavior is examined. Using multi-wave data collected from 113 employees across diverse industries in Taiwan, the study employed an experience sampling methodology to capture dynamic, real-time data on participants' weekly experiences over a nine-week period. Multilevel path analysis revealed that in-role intrusions positively influence information sharing, which in turn enhances task performance and innovative behavior. Moreover, information sharing was found to mediate the relationship between in-role intrusions and both task performance and innovative behavior, demonstrating its critical role in bridging these constructs. Finally, psychological capital was shown to moderate the relationship between information sharing and innovative behavior, highlighting its importance in fostering creativity in the workplace. This study contributes to the theoretical understanding of workplace intrusions by uncovering their potential benefits under specific conditions, while offering practical insights for organizational strategies aimed at enhancing performance and innovation.
