The present research endeavours to ascertain the rational decision-making style of public sector workers (PSWs) and their impact on entrepreneurial opportunities in Ghana. In particular, the study examines the mediating role of entrepreneurial intention and the moderating effect of social capital. To test the hypotheses, a sample of 358 PSWs was analysed using a structural equation modelling (SEM). The findings reveal that decision-making style has a significant effect on entrepreneurial intention, opportunity development, and opportunity creation, respectively. Furthermore, the research supports the mediating role of entrepreneurial intention, which manifests itself as a crucial conduit between decision-making style and both opportunity development and opportunity creation. The study emphasises the imperative for policymakers to foster a robust social environment that nurtures the Ghanaian PSW community. The study posits that entrepreneurial opportunity creation can be substantially enhanced by encouraging these workers to explore and create business ventures.
