This study assesses the role of psychological safety as a mediating factor in the association between procedural justice and turnover intention within the context of a banking institution situated in Tunisia, specifically ABCD Bank, which has its headquarters and a few branches dispersed across Tunis, the capital, and adjacent towns. Despite the burgeoning body of literature individually exploring these three constructs, there exists a notable dearth of research that concurrently integrates them. Consequently, a self-administered questionnaire was distributed to 613 employees spanning various grades and genders, employed at both the headquarters and branches of ABCD Bank. The analysis of the structural equation modelling data was conducted using AMOS software. The findings of the study reveal a statistically significant and positive relationship between procedural justice and psychological safety. Moreover, procedural justice exhibits a statistically significant and negative association with turnover intention. Conversely, psychological safety demonstrates a statistically significant and negative impact on turnover intention. The study concludes that psychological safety partially mediates the connection between procedural justice and turnover intention. Beyond its theoretical implications, the outcomes of this research are anticipated to yield managerial and methodological recommendations tailored for human resources practitioners and academics, underscoring the substantive role of both psychological safety and procedural justice in fostering employee retention.
