Perceived dissimilarity and knowledge sharing with younger workers: the role of generativity striving and knowledge receiving from younger workers

Abstract Drawing on self-categorization theory, this study examined the impacts of perceived age and deep-level dissimilarities with younger workers on older workers’ tacit and explicit knowledge sharing (KS) with younger workers via generativity striving (GS), and extended the theory by proposing the moderating role of knowledge receiving (KR) from younger workers. This study used a three-wave online survey of 570 older workers in a large Chinese aircraft maintenance company. The results showed that GS mediated both the positive relationships between perceived age dissimilarity with younger workers and older workers’ tacit and explicit KS with younger workers, as well as the negative relationships between perceived deep-level dissimilarity (PDD) with younger workers and older workers’ tacit and explicit KS with younger workers. Moreover, the positive direct impact of GS and the negative indirect impact of PDD with younger workers on older workers’ explicit KS with younger workers were found to be relatively weaker when older workers’ KR from younger workers was high. The findings suggest that perceived age and deep-level dissimilarities with younger workers present both opportunities and challenges for older workers to share knowledge with younger workers.
