Purpose: Idiosyncratic deals (I-deals), a novel human resource management implement, has significantly contributed to attracting, retaining and motivating personnel to enhance creativity. Building upon self-categorization theory, this study investigates the impact of I-deals on creativity and the moderating role of psychological safety in this process by perceived insider status.
Participants and Methods: To mitigate common method bias and causal lag effects, this study was conducted in three phases with a half-month interval for data collection. In this study, a total of 331 employees from six enterprises in China were selected to test the hypotheses using Bootstrap and Johnson-Neyman methods.
Results: Results show that I-deals have a positive influence on creativity. Perceived insider status acts as intermediary between I-deals and creativity; Psychological safety strengthens the influence of I-deals on perceived insider status and further enhances the indirect influence of I-deals on creativity through perceived insider status.
Conclusion: This study demonstrates that organizations can leverage the unique characteristics of I-deals to fully showcase the diverse talents of their personnel, while simultaneously enhancing their psychological security. This, in turn, empowers employees to confidently propose new ideas and methods, thus catalyzing the generation of creativity.
