The concern for the work-life balance of employees has increased due to the increasing demands made by the banking industry, as reflected by increased work hours, performance, and customer-centric business operations. The current study aims to investigate the influence of Perceived Organizational Support (POS) on work-life balance, job satisfaction, and well-being in the banking industry, as predicted by Social Exchange Theory. A quantitative, theory-driven research method will be employed to obtain data from approximately 350 banking industry professionals using probability sampling techniques. Perceived Organizational Support and work-life balance will be measured using standardized scales. For robustness, the current study will utilize the bootstrapping method, hierarchical regression, mediation, moderation, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). The findings are expected to reveal that Perceived Organizational Support significantly contributes to well-being and work-life balance, and job satisfaction will be the mediating factor. Additionally, the findings are expected to reveal that sector types, i.e., public and private, will moderate the relationships. The current study will contribute to the body of knowledge on work-life balance, as it extends Perceived Organizational Support theory to work-life balance in the banking industry, and it will provide practical implications for HR professionals in the banking industry
