Because career developments over time are linked, careers and ageing should be looked at in an integrative way in order to acknowledge that careers span the whole life of a person. Many studies on careers, however, consider persons “out of their age context” and/or at “one specific point in time.” Up to now, career theory has not directly examined the criteria older workers use to evaluate their success in coping with ageing in the workplace (see also Robson et al., 2006). Given the fact that older workers are the fastest growing demographic category, and because they are at the same time a very diverse group, empirical research is needed to cover factors that contribute to or hinder successful ageing throughout the career.
