5.1. Summary of findings and contribution to current knowledge Our study was aimed at proposing and testing a research model that examined the mediating role of PsyCap in the association between servant leadership and WE and WE as a mediator between PsyCap and service recovery performance and life satisfaction. Based on data obtained from flight attendants with a time lag of two weeks in three waves and their pursers in Iran, the results provided support for almost all hypothesized relationships. The results suggest that management of airline companies that possesses servant leadership qualities fosters flight attendants’ personal resources such as PsyCap. That is, flight attendants are self-efficacious, hopeful, resilient, and optimistic when management sends powerful signals to them about the presence of servant leadership practices by forming relationships with subordinates, empowering subordinates, or displaying ethical behaviors.
