Career shocks (CS) avert recipients' growth and consider the main hurdle in the development of employees' career. Such shocks (positive/negative) significantly affect employees. Drawing on affective events theory (AET), this study conceptualizes CS as affective events which produce negative/positive behavior among individuals. Therefore, this study aims to explore the influence of CS on career development (CD) through positive affect using AET as a theoretical base. Moreover, this research pursues to explore that how family support plays a buffering role in the association between CS and CD. Using the time-lagged approach, we recruited 264 banking professionals and tested the proposed model in AMOS 24.0. The findings demonstrate that CS is significantly related to CD and family support moderates the linkage between CS and CD. Finally, we recorded the research discussion and implications.
