Background: Increasing numbers of people are delaying retirement. Studies of their motives are scarce and biased to Western contexts. Aims: The aim was to explore internal and external motives of older Slovenians who continue to work after becoming eligible for retirement. Methods: Nine workers, aged 59-72, were interviewed. The interviews were analysed using thematic analysis. Findings: Three main themes were extracted. The 'Foundations' described the prerequisites for continued work engagement that were often non-negotiable. The 'Rewards' included the benefits of working and suggested a strong pull towards the non-material aspects of work. 'Negotiating occupational challenges' summarized an internal crisis that was experienced when faced with a potential occupational void of retirement. Conclusions: Although the participants' motivations were not homogenous, we identified a pattern in the way they constructed their motives in relation to the occupational life trajectories and contextual factors. Based on our findings and multidisciplinary theories, we proposed a hierarchy of motives for prolonged work activity. Significance: The study offers an occupational perspective of the phenomenon of delayed retirement and argues that the efforts of the discipline of occupational therapy should be directed at different levels of motives, including empowering people to nurture higher level occupational motives.
