Prolonged and productive employment of older workers is a necessary condition to maintain welfare and social security systems threatened by ageing populations. Yet not much is known about the factors that define the opportunities for older workers in the labour market. The current study has evaluated which individual characteristics of older workers, organisations and managers affect managers' decisions to hire older workers, offer them training opportunities and retain them in organisations, as well as the potential role of managers' attitudes on their behaviour with respect to older workers.
