Knowledge forms a crucial source for gaining competitive advantage and its sharing a dominant challenge facing several organizations. In this paper we propose a positive role of workplace spirituality (WPS) (at individual and collective levels) on knowledge sharing intention (KSI) by employing the theory of decomposed planned behaviour. We argue that WPS with its focus on inner spirit, meaningful work, sense of interconnectedness and alignment with organizational values and mission positively strengthens an individual’s knowledge sharing attitude, subjective norms and perceived (...) behavioural controls (thereby, strengthening their KSI) by affecting the underlying behavioural, normative and control beliefs. We also take into account the role of transformational leadership (TL) in creating a pro-social working environment, which facilitates knowledge sharing. In proposing a holistic and multi-level framework linking WPS (at individual and collective levels) and TL with KSI, this paper contributes to both, knowledge sharing and WPS literatures. (shrink)
