Purpose This study aims to examine the impact of innovative work behaviour (IWB) on sustainable innovation in micro-enterprises. While IWB is recognised as a driver of innovation in larger firms, its role in small-scale businesses remains unclear. This research investigates whether IWB fosters social and ecological innovations in micro-enterprises. Design/methodology/approach The study is based on survey data from 1,848 Polish micro-enterprises. A multivariate probit model (MVP) is used to assess the relationship between different dimensions of IWB (idea generation, exploration, championing and implementation) and sustainable innovations, measured according to the OSLO Manual and European Commission frameworks. Findings The results show that only idea exploration (seeking improvements beyond routine tasks) and idea implementation (efforts to develop new solutions) have a significant influence on sustainable innovation. Other IWB dimensions, such as idea generation and championing, have no significant effect. This suggests that proactive problem-solving and applied innovation are key to advancing sustainability in micro-enterprises. Practical implications Micro-enterprises should prioritise fostering employee behaviours related to exploring and implementing innovative solutions. Policymakers and business leaders should focus on training programs that enhance these capabilities to support ecological and social innovation. Originality/value This study provides empirical evidence on how IWB influences sustainability in micro-enterprises, an under-researched sector. By identifying the most impactful dimensions of IWB, it offers valuable insights for both academia and practice.
