Purpose: The purpose of this study is to investigate the role of organizational learning culture as an enabler of knowledge-sharing behaviours and workplace spirituality. A model is proposed to examine the mediating role of knowledge-sharing behaviours between organizational learning culture and workplace spirituality. Design/methodology/approach: Employees from various Thai industries participated in the study, and structural equation modelling was used to test hypothesized relationships. Findings: Results suggest a positive relationship between organizational learning culture and workplace spirituality, partially mediated by knowledge-sharing behaviours. Research limitations/implications: The study was limited to Thailand, and is a cross-sectional design. Further investigation into the causality of relationships and cultural disparities is needed. Practical implications: Friendly learning environments enable both knowledge sharing and change organization members' views regarding learning and performance improvements for organizational sustainability. Originality/value: This paper bridges a gap between theory and practice concerning the outcomes of organizational learning and factors that lead to workplace spirituality.
