Circular Happiness: Building Sustainable Workplaces for the Next Generation explores how businesses can merge sustainability and employee well-being by applying circular economy principles to create eco-friendly, fulfilling work environments. Focused on the needs of Gen Z, the book provides a framework for organisations to foster both environmental sustainability and mental health, offering practical strategies for enhancing workplace happiness while addressing climate change challenges. In response to growing demands for sustainable practices and increasing workplace mental health issues, this contributed volume offers actionable insights for integrating circular economy models with employee well-being initiatives. At the heart of the book lies the concept of “Haptitude” — a fusion of Happiness, Attitude, and Result. It represents a measurable, action-oriented approach to cultivating sustainable happiness practices within organisations. By embedding Haptitude-driven strategies into workplace culture, leaders can create environments that not only enhance well-being but also drive long-term engagement, creativity, and organisational resilience. Circular Happiness is an essential guide for building a thriving workplace that benefit both people and the planet.
