The edited volumeAge and Work: Advances in Theory, Methods, and Practicepresents a systematic collection of key advances in theory, methods, and practice regarding age(ing) and work. This cutting-edge collection breaks new ground by developing novel and useful theory, explaining underutilized but important methodological approaches, and suggesting original practical applications of emerging research topics.The book begins with a prologue by the World Health Organization's unit head for aging and health, an introduction on the topic by the editors, and an overview of past, current, and future workforce age trends. Subsequently, the first main section outlines theoretical advances regarding alternative age constructs (e.g., subjective age), intersectionality of age with gender and social class, paradoxical age-related actions, generational identity, and integration of lifespan theories. The second section presents methodological advances regarding behavioral assessment, age at the team and organizational levels, longitudinal and diary methods, experiments and interventions, qualitative methods, and the use of archival data. The third section covers practical advances regarding age and job crafting, knowledge exchange, the work/nonwork interface, healthy aging, and absenteeism and presenteeism, and organizational meta-strategies for younger and older workers. The book concludes with an epilogue by an eminent scholar in age and work.Written in a scientific yet accessible manner, the book offers a valuable resource for undergraduate and graduate students, academics in the fields of psychology and business, as well as practitioners working in the areas of human resource management and organizational development.
