The Sloan Center on Aging & Work at Boston College has published a study of employees' work experience, finding that those 40 years old and older are the most engaged and demonstrate the highest level of organizational commitment, and that those 50 years old and older are the most satisfied with their jobs. The "Generations of Talent Study" assessed the effects of country, age, and career stage among employees worldwide, based on work experiences from 11,298 individuals, working for seven multinational companies, at 24 worksites in 11 countries.
Among other things, the study found that employees working in young-developing countries (Brazil, China, India, Mexico, South Africa, Botswana) show higher levels of work engagement and organizational commitment than do those in the old-developed countries (Japan, the Netherlands, Spain, UK, U.S.). In contrast, job satisfaction levels are similar on average for employees working in the young-developing countries and in the old-developed countries. Dr. Marcie Pitt-Catsouphes, Director of the Sloan Center, noted that "[c]ontrary to popular opinion, older workers are the most engaged, and forward-thinking companies need to begin strategizing about how to capitalize on this asset."
In addition to an overall report on "Effects of “Old-Developed” versus “Young-Developing” Country Type and Age-Related Factors on Work Engagement, Job Satisfaction, & Organizational Commitment," the Sloan Center has published individual reports about the effects of country and age on employees for the following countries:News Release (December 1, 2011)
