Ageism toward older workers is prevalent in the labor market. The present study aimed to understand psychosocial mechanisms that may counteract this form of discrimination and help retain workers in the labor force. Using a sample of 500 Canadian younger and older workers, this study tested a model hypothesizing that intergenerational contacts and knowledge sharing practices can reduce ageist views about older adults and age-based discrimination against one's own group, and in turn, enhance work engagement and intentions to remain in the workplace. The final model shows that knowledge sharing practices mediate the relationship between intergroup contacts and positive views about older workers as well as age-based discrimination. It also suggests that low levels of age-based discrimination increase work engagement and intentions to remain in the organization for workers of all ages. Practice and policy implications are discussed.
