Purpose Flexibility in the workplace is increasingly considered an important aspect of human resource strategy aimed at attracting and retaining a high-quality workforce. The purpose of this study is to explore the direct relationships between both employee- and employer-centered flexible work arrangements and turnover intentions, specifically focusing on Generation Z employees. In addition, this study also examines the mediating role of supervisor support and total rewards in these relationships. Design/methodology/approach This study used a quantitative research design using a cross-sectional survey method to gather data from employees born from 1995 across three industries – logistics, retail sales, and manufacturing. Partial least-squares structural equation modeling was used to analyze the data. The survey was conducted online, ensuring a diverse geographical spread and adherence to the representativeness of Generation Z within these sectors. Findings Contrary to existing literature, the findings reveal no direct correlation between flexible working arrangements (FWAs) and turnover intentions in this demographic. Instead, the results highlight the significant mediating roles of perceived supervisor support and total rewards. Specifically, these factors were found to influence turnover intentions in relation to the availability of employee-centered FWAs. The findings provide theoretical and practical implications, suggesting an adaptation of human resource strategies to better align with the preferences and expectations of Generation Z in the workplace. Originality/value In contrast to existing literature, this study examines the relationship between the availability of two different types of flexible work arrangements (employee- and employer-centered) and turnover intentions, specifically among Generation Z employees. In addition, this research introduces mediation analysis to investigate the roles of perceived supervisor support and total rewards – constructs that have been rarely considered in the context of these relationships.
