This study aimed to develop a qualitative theoretical model explaining how leadership philosophy evolves from a narrow efficiency-oriented logic toward a human sustainability-oriented paradigm in contemporary organizations. This qualitative theory-development study was conducted using semi-structured interviews with 24 senior managers, middle managers, organizational development specialists, human resource professionals, and leadership consultants working in Tehran-based organizations. Participants were selected through purposive and theoretical sampling to capture diverse experiences of leadership transformation across private, public, technology, service, and knowledge-intensive organizations. Data collection continued until theoretical saturation was reached after the twenty-first interview, followed by three additional interviews for model refinement and confirmation. Interviews lasted between 45 and 80 minutes and focused on participants’ experiences of efficiency-driven leadership, human costs of performance pressure, changes in leadership assumptions, and emerging practices of human sustainability. All interviews were transcribed verbatim and analyzed using grounded theory procedures, including open coding, axial coding, selective coding, constant comparison, memo writing, and category integration. NVivo software was used to organize transcripts, develop codes, compare categories, retrieve quotations, and support analytical transparency. Analysis generated five main categories: mechanistic efficiency orientation, recognition of human depletion, ethical-relational reframing of leadership, integration of performance and human sustainability, and emergence of regenerative leadership philosophy. The central category was identified as “leadership as stewardship of sustainable human capacity.” The proposed theory suggests that leadership philosophy evolves when organizations recognize that short-term efficiency without human renewal produces burnout, distrust, disengagement, and fragile performance. Human sustainability-oriented leadership reframes employees not as resources to be optimized but as meaning-making, relational, and developing human beings whose energy, dignity, learning, and voice must be protected. The study contributes to leadership theory by explaining the philosophical transition from control-based efficiency toward human sustainability. It offers a conceptual framework for organizations seeking to balance productivity, well-being, ethical responsibility, and long-term adaptability.
