The dynamic demographic changes in Poland, leading to an ageing population, are significantly affecting the labour market. Given the declining number of working-age people and the rising share of the post-working age population, it is becoming important to look for effective solutions to counteract the growing labour force shortages. Therefore, the main objective of this article was to identify the key challenges related to the increasing number of people in the post-working age group and the decreasing number of people in the working-age group, as well as to assess the employment potential of foreigners as a response to the problem of the ageing population in Poland. The above objectives were achieved through an analysis of the available domestic and foreign literature and statistical data, including data from the Central Statistical Office and the Ministry of Labour and Social Policy. The considerations presented in the article lead to the conclusion that the introduction of innovative solutions, such as the employment of seniors and foreigners, may contribute to balancing future tensions in the labour market in Poland. In this context, hiring foreigners, due to their availability and ability to quickly integrate into the workforce, is seen as a strategy that can fill labour shortages more quickly, as opposed to waiting to increase labour force participation among the domestic workforce, which is a much longer and more complex process.
