Abstract
Based on the premise of organizational support theory this study investigates the relationship between perceived organizational support and citizenship behavior of employees. The study offers a novel explanation by testing the sequential mediation through well-being and work engagement. Data was collected from 273 employees from diverging service organizations working in Lahore and its nearby cities. Results of the study revealed that POS has a direct bearing on citizenship behavior, but sequential mediation relation is not proved. Though the findings are against the hypothesized relations, but can still offer new theoretical directions and implications for practices. Limitations and future directions are also given at the end.
