Due to the ageing of the population and the consequent changes in care models for dependent older people, it is becoming necessary to highlight the economic (including pensions) security problems faced by informal carers. In many cases, people caring for a dependent family member are forced to leave employment. Such a decision is not only associated with economic or emotional problems, but also results in a reduction of the carer's future pension benefit. This article aims to discuss and evaluate the security system for carers of dependent older people who, due to the need to support and care for an elderly family member, have decided to leave the labour market. Particular attention will be paid to the analysis of the role of the nursing benefit in the system of carers' security and the problems related to both the decision granting and refusing to grant this benefit.
