The notion of people in their environment is critical to understanding the future of work. Socio-ecological means people in their environments, which is the fundamental premise of open systems. Tropophilia, as discussed in this book, is built on the socio-ecological model of open systems. The view of Tropophilia, outlined and discussed in this book, highlights the importance of an enabling organizational environment, with emphasis on the philosophy of future Human Source* (HS) practices, which is a consequence of Open Systems Design Principles (OSDP). The tropophilia, thus developed by the organizational structure, shall lead beyond resilience and antifragility. Inherent and adaptive resilience, which is posited as worker resilience, can be enacted in a range of environments on the premise that the organization is building that resilience through a combination of HS practices based on OSDP. This book focusses on the fact that the onus for developing Tropophilia, in order to go beyond resilience and antifragility, does not rest just on a joint activity involving workers and the organization's top management, but on their continuous directive correlation with their environment. An agile and lean system, built on OSDP, critical thinking, and ideal-seeking behavior, can be developed through a radically different approach to the anachronisms of traditional symptoms-based approaches of "HR" practices. Thus, building the foundation of a Tropophillic Organization which is how a few savvy CEOs are leading the way and thriving on uncertainty. * I find Human 'Resource' demeaning. Hence, the use Human 'Source' throughout this book.
