The aims of this paper are to: 1) examine the prevalence of HR (HRM and HRD) practices to retain older workers in healthcare organizations; 2) evaluate those HR practices that are specifically designed to facilitate the retention of older workers, and; 3) classify those HR practices against the needs of older workers, line managers and HR professionals. To achieve these aims, 51 interviews have been conducted with older workers, line managers, and HR professionals working in 15 Dutch hospitals and care service organizations in late 2010. The study had a mixed-methods set-up in that the collected information was partly quantitative (figures about the prevalence and outcomes of practices), and partly qualitative (incorporating illustrative reflections or observations offered by interviewees), the latter complementing the former. Maintenance HR practices (practices that are focused on retaining older workers in their current jobs) appeared to be by far more prevalent compared to development HR practices (practices that are focused on advancement, growth and accomplishment, and that encourage individual workers to achieve new and challenging levels of functioning). In general, both types of HR practices were evaluated as successful byolder workers, line managers and HR professionals. Unexpectedly, the successful evaluations of the maintenance practices appeared to be attributed to developmental rather than 1 We would like to thank the reviewers of this article for their highly constructive comments. Development (f) In the face of the rapid ageing and 'dejuvenization' of the working population across most of the developed world in the 21 st century (Hedge & Borman, 2012;Schalk et al., 2010;Shultz & Adams, 2009;Van der Heijden et al., 2010), there is a need to promote better employment opportunities for older people (OECD, 2012). Internationally, the most populous age group has shifted from the 20-24 group in 1980 to the 30-34 group in 1990, and, subsequently, to the 40-44 group in 2010 (Steemers, 2010). In a similar vein, in European Union member states an average increase of 12% in the proportion accounted for by the 50-59 age group has been predicted over the next 10 years (Inceoglu, Segers, & Bartram, 2012, p. 300).Therefore, due to the expected workforce shortage, better and longer working careers are urgently needed to finance and support the longer life of European citizens (Ilmarinen, 2005(Ilmarinen, , 2009). In the 21st century, the number of young empolyees will be too few to replace those who retire, which could be detrimental for the economic growth. The issue at stake here is doing more with fewer workers and, at the same time, with a workforce consisting of relatively more older workers (Collins, 2003). Though retention of older workers might not be an appropriate strategy in some types of organizations, due to specific skill and capabilities' requirements that are age-dependent, it may be assumed that, in general, a greater utilization of the workforce segment of older workers will be an important appr...
