The objective of this study is to analyze the effects of supervisor knowledge hiding (SKH) on the job performance of supervisees in the manufacturing sector. The study creates a conceptual framework that depicts the relationships between SKH, supervisee job-based PO and supervisee job performance. The author investigated how SKH affects the output of subordinates as well how to mitigate SKH's detrimental impact on supervisee job performance, and in what way supervisee job-based PO act to decrease the negative effect. This paper examines a mediation model that is grounded on the conservation of resources (COR) theory. The data was obtained from 347 employees who were serving in the manufacturing industry of Southern Punjab, Pakistan. Through the implementation of a quantitative research design and extensive analysis of data, findings reveal that SKH negatively impact on subordinates that ultimately reduce the performance of supervisees at workplace. This research contributes to the recent finding that the adverse effects of SKH can potentially be buffered through the supervisee's possession. The model test with Partial Least Squares (PLS)-4 was used as the analysis technique in the study. Based on the available information, this is the first study to look into the relationship between SKH, supervisee job performance and supervisee job-based PO using conservation of resource (COR) theory. The authors switched the focus that conservation of resource (COR) theory offering new ideas into the process behind the link between SKH and supervisee job performance. This research also looked at how SKH hiding in the workplace affects job-based PO. This research focuses on workplace behavior. Employee attributes can dissuade a negative reaction to SKH. The effect of SKH on supervisees can be mitigated by focusing on supervisee job-based PO. This is an increasing push to focus on workplace positivity, which improves supervisees' job performance. It is imperative that we investigate the reasons how employees can perform effectively at work while remaining loyal and devoted to it.
