The idea of Circular Human Resources (CHR), a new paradigm that rethinks human capital management from the perspectives of sustainability, adaptability, and long-term value creation, is introduced in this chapter. By advocating for tactics that emphasize retention, reskilling, internal mobility, inclusivity, and regenerative work practices, CHR—which has its roots in the circular economy—challenges conventional linear HR models. The chapter outlines the foundational theories and drivers behind CHR, including environmental, social, and governance (ESG) imperatives, technological advancements, and shifting workforce expectations. It explores how CHR aligns with global priorities such as the United Nations Sustainable Development Goals (SDGs), the future of work, and evolving labor market demands. The potential of CHR to turn workplaces into resilient, human-centered ecosystems that are both economically and socially responsible is highlighted in this chapter through case studies and cross-cultural insights.
