This research examines the active engagement of employees in sustainability and helps create a workplace culture that emphasizes shared responsibility for environmental and social impact. It investigates how employees’ engagement in sustainability development is achieved, the barriers to enhancing this engagement, and how responsibility can be embedded in various organizational cultures across industries and countries. The review combines a comprehensive literature review with comparative case studies from various sectors and regions. For example, Unilever and Patagonia’s case studies focus on best practices in those areas where sustainability objectives are best aligned with employee behavior. Engaged employees are recognized as critical agents of change, enhancing sustainable practices and boosting organizational performance. For example, Amazon facilities, unclear sustainability goals, and inconsistent leadership approaches impede. Any conclusions drawn might be limited since the work relies on secondary data and case studies. Future studies should integrate empirical research to account for sector and regional differences that come into play in employee responses towards sustainability. The study gives several actionable insights to managers, such as Unilever, IKEA, Amazon, and Patagonia to describe the variety of approaches towards sustainability. Higher employee engagement leads to sustainable behaviors, which results in reduced environmental impacts and enhanced social justice within communities. By connecting employee engagement with sustainability, this global analysis provides a treasure trove of insights into new avenues for embedding ethical, responsible, and culturally adaptive practices in corporate cultures.
