Knowledge sharing is a key competence in a work context. In this study we address knowledge sharing from an individual difference perspective, exploring whether an employee’s sense of coherence influences knowledge sharing. Additionally, we investigate whether dedication to diversified learning mediates the relationship between Sense of Coherence (SOC) and knowledge sharing. A survey was conducted in a multinational organization. We received 403 responses. Partial least square structural equation modeling was used to analyze the data. The results show that SOC significantly influences the respondents’ self-perceived knowledge sharing activities. However, the relationship is partially mediated by dedication to diversified learning. Results suggest that an employee’s knowledge sharing partly arise from personal characteristics. How much is shared in actuality, however, depends on motivation and contextual factors.
