The aim of this article is to draw attention to the growing phenomenon of working in retirement in the light of active and successful aging concepts. The change in attitudes towards aging, work and retirement among Poles can be seen as a kind of social process that has been ongoing since the early 1990s. Nowadays, more and more people of retirement age, anxious to remain active and independent for as long as possible, are delaying the moment of professional deactivation. The article presents the partial findings of research conducted by the author. The purpose of the qualitative study ”Attitudes towards retirement and type of reflexivity as determinants of positive aging” was to characterize the motivations for career continuation and the benefits of prolonged professional activity among people over 60. The findings—concerning participants considered professionals (n = 20) according to the International Standard Classification of Occupations ISCO-08—suggest that continuing one’s career after reaching retirement age can be considered one of the strategies for achieving successful aging.
