The aging of baby boomers, along with the predicted decrease of the available labor pool, will place increased scrutiny and emphasis on issues relating to an aging workforce. Furthermore, future economic downturns will place strong pressure on older workers to remain in the workforce, and on retirees to seek employment again. "Aging and Work in the 21st Century" reviews, summarizes, and integrates existing literature from various disciplines with regard to aging and work. Chapter authors, all leading experts within their respective areas, provide recommendations for future research, practice, and/or public policy. This definitive source comprehensively reviews: trends and implications regarding the demography, income, and diversity of the aging workforce; the issue of age bias in the workplace; job performance, work-related attitudes, training and development, and career issues of older workers; and topics of age and occupational health, technology, work and family issues, and retirement. The intended audience is advanced undergraduate and graduate students, as well as researchers in the disciplines of industrial and organizational psychology; developmental psychology; gerontology; sociology; economics; and social work. Older worker advocate organizations, like AARP, will also take interest in this edited book.
