In contemporary times, there has been a notable surge in companies’ attention toward the welfare of their employees. Employee well-being is no longer solely contingent upon financial incentives. Factors such as the work environment, corporate social responsibility (CSR) initiatives, green practices, and organizational culture have emerged as pivotal considerations among employees when evaluating job satisfaction. Through a structured questionnaire administered to employees across various industries, data were collected on perceptions of organizational culture, CSR practices, green initiatives, and self-reported levels of happiness. Utilizing Smart PLS 4 analysis, a robust statistical model was constructed to examine the interplay between these variables. Our research reveals a significant positive correlation between CSR endeavors, encompassing green practices, and employee happiness. Through elucidating the pathways via which CSR and green initiatives impact employee well-being, this study provides valuable insights for fostering a comprehensive approach to corporate sustainability and employee contentment. These results emphasize the strategic necessity for organizations not only to prioritize CSR and green practices but also to integrate them within their organizational culture, thereby enhancing both employee well-being and overall organizational effectiveness.
