The spread of the COVID-19 pandemic has brought unprecedented challenges to pharmaceutical companies and their employees. Over the past three years, intensive antipandemic tasks have placed high demands on the physical and mental strength of pharmacy professionals. By using a questionnaire, data were collected from 391 technicians in pharmaceutical companies from southern coastal areas of China. The study examined the influence mechanism of organizational learning on employee adversarial growth with the moderating effect of resilience. Our analysis shows that adaptive and experimental learning promote employee adversarial growth by enhancing individual role-breadth self-efficacy. Moreover, resilience reinforces the positive effect of organizational learning on role-breadth self-efficacy. The results imply that in a complex and changing environment, experimental learning has greater value for organizations to respond to crises and enables employees to promote personal growth.
