In view of global population ageing and of policies that support longer working lives, especially in developed countries, it is important to achieve diversity in organisations through age management. Age management is the “management of human resources, [often] with an explicit focus on the requirements of an ageing workforce.” Through age management practices, organisations will be better able to change their human resource management policies and practices towards accommodating their ageing workforce. Little is known about age management practices in Scandinavian organisations, considering the region’s high prevalence of workers beyond the age of 50 across both private and public organisations. There are indications that Scandinavian business organisations are already practicing age management for all ages, including older workers. Their age management practices include the dimensions of job recruitment, training, lifelong learning, development, and promotion. However, there is a dearth of knowledge on how the health and well-being of workers is ensured in the context of age management practices in these organisations. Given the current and future importance of age management for all organisations globally, public health and other health science professionals need to collaborate with other disciplines, such as management and sustainability science, to better understand how they can contribute to an aged and healthier workforce as well as workplace health promotion. This paper aims to contribute to the discussion concerning age management in public and private institutions in Scandinavia through the public health lens.
