Purpose: The aim of this study is to enhance diversity, equity, and inclusiveness (DEI) culture by using individuals' learning engagement (ILE) as a catalyst with formal and informal learning engagement interventions for sustainable learning and performance. Design/methodology/approach: As part of a transdisciplinary study (DEI and learning), a mixed method was used. The data from 16 semi-structured interviews (SSI) with corporate professionals was analysed to create the ILE framework for enhancing DEI culture. A focus group discussion and experimentation were used for validation as triangulation. Findings: The suggested ILE framework had a considerable impact on DEI. Findings revealed a positive, statistically significant association between ILE and DEI cultural enhancement describing how participants' ILE experiences impacted their DEI perspectives, demonstrating compelling evidence of DEI culture enhancement. Practical implications: This study proposes a sustainable learning approach for a multi-cultural workforce by using the ILE framework for business, HR, DEI and L&D experts to enhance DEI culture. Originality/value: The study contributes to DEI and learning engagement domains with a framework for integrating all three elements of DEI by using impactful ILE interventions.
