The workforce across industrialized nations has become both older and more age-diverse, and this trend is expected to continue in the coming decades. These changes will have important implications for motivating and managing both individual employees and teams and because people are retiring later, it is important to address ways to sustain the wellbeing and productivity of workers.With a specifically international focus, this volume addresses these critical issues from the individual and psychological perspectives. Based primarily in empirical research, it covers a wide range of topics related to the aging workforce, including the motivation of older workers – to work and to retire; what organizations can do to attract and retain the talent of older workers; how to improve relations and productivity among age-diverse teams; how to design jobs to support older and younger talent; and how to better understand why older workers may choose to return to work. This volume includes contributions from the top psychological researchers in the field of the aging workforce.This book was originally published as a special issue of the European Journal of Work and Organizational Psychology.
