The aim of the study is to present the idea of volunteering, which is becoming increasingly noticed by political decision-makers as an instrument for activating senior citizens. The text offers a look at the issue from a different perspective, i.e., senior citizens as potential volunteers. The article begins by recalling the theories and concepts of activity that had a significant impact on senior policies. The second section focuses on volunteering as an instrument for activating senior citizens. The activity of elderly people in Poland, both in terms of work and involvement in volunteering, places Poland behind most European countries. Then the author presents the benefits and analyses some of the barriers that may limit or prevent this type of older people’s activity. The article concludes with the statement that being an active senior citizen requires systemic support, especially when caring responsibilities for dependent aged relatives must be combined with professional work.
