Growth

Population longevity and rapid digital transformation are changing labor markets and career paths. Novel careers like portfolio careers, hybrid work, sustainable careers, and senior entrepreneurship are driving different approaches to human capital development and human resource management. The relationship between longevity, HR transformation, and new employment models within the longevity economy is examined in this study. This research draws on relevant literature from labor economics, human resource management, sustainable careers, and organizational innovation, and constructs an integrated framework around demographic ageing, employability, career sustainability, and organizational adaptation. The research demonstrates that longer life expectancy will compel career paths that are more flexible, multistage, and adaptive based on the recently published empirical evidence on workforce ageing and the silver economy, supporting an interdisciplinary conceptual approach. At the same time, organizations are challenged to modernize talent management, lifelong learning, and age-inclusive HR practices. Individual ambidexterity, continuous skills development, and senior entrepreneurship are highlighted in the paper as mediators of career sustainability in extended working lives. It contends that, rather than considering this growth as solely a demographic burden of increasing longevity, the longevity economy should be seen as a chance for a greater role of innovation, productivity, and social inclusion. The study adds to the growing literature relevant to the topic of longevity and labor market transformation by connecting macroeconomics with organizational and individual perspectives, and includes a consolidated model useful for researchers, policy-makers, and HR professionals.
