This study examines the influence of perceived corporate social responsibility (CSR) on corporate financial performance (CFP). Based on win-win paradigm, this study uncovers the mediating role of Quality of Work Life (QWL) on CSR-CFP nexus. A questionnaire based cross-sectional survey was conducted to accumulate data from 355 employees working in public and private sector banks of Pakistan. Structural Equation Modeling (SEM) was used to examine the hypotheses. The results depict that CSR is positively related with CFP, and employee QWL partially mediates this relationship. According to our noesis, the review of previous literature regarding the association of CSR and CFP reveals that QWL has not been empirically tested as a mediator between these two variables. This study findings proposes that banks engaged in CSR activities are actually establishing a healthy work environment for their employees which ultimately helps the banks to improve their financial performance. This study highlights the importance of CSR activities for enhancing the CFP of the banking sector in the developing countries.
