<p>Corporate social responsibility (CSR) covers a wide range of activities. Higher education institutions (HEIs) also engage in CSR actions, thus playing a significant role in society, seeking to promote education for a sustainable future. Most existing CSR studies have focused on companies and in their business operations, neglecting the CSR activities of HEIs. Accordingly, this study focuses on how CSR activities of HEIs affect their students’ well-being through organizational pride and employability. Moreover, the research examines a curvilinear relationship between CSR and well-being. To test the research model, we used data collected through a survey questionaire completed by 321 Portuguese university students. To do so, we used structural equation modeling techniques. The results suggest that student’s perception of CSR relates positively to their well-being, organizational pride, and employability. The results also show that the path between CSR as perceived by students and their well-being is set up not only directly, but also through organizational pride and employability. Additionally, the results reveal a curvilinerar relationship between CSR dimensions and student well-being. This study extends the literature by addressing students’ emotional reactions to the CSR activities of their HEIs: it focuses on the effects of current emotional HEI-related effects (organizational pride and employability), but also long-term effects (well-being) on the individual. Additionally, this research advances current research by theorizing a curvilinear relationship between CSR and well-being.</p>
