The unstable employment trajectories and low wages of Chilean workers mean that the amount of savings accrued in pension funds are often insufficient to cope with the high costs of living in the country, compelling many older adults to remain in the labour market. Although financial need seems to be an important reason for post-retirement work in Chile, a national survey revealed that a majority of older workers would like to remain employed even if there were no economic need. Hence, this research aims at exploring the intrinsic work motivation of older Chilean adults beyond retirement age. This qualitative study is the second phase of mixed-methods research to analyse the factors influencing post-retirement work in Chile. A total of 32 in-depth face-to-face interviews were conducted with older workers in the formal labour market who were legally entitled to retire but continued being economically active in Santiago, Chile. The data are analysed using thematic analysis. We identify three main emerging themes, namely the meaning that work gives to life, future projects and post-retirement orientations, and work as the primary source of social interaction. The findings of this study provide valuable insight into intrinsic work motivation, highlighting important gender and occupational differences. It makes a significant contribution not only to the literature but also potentially to national policy makers as well as employers, indicating the need to adjust the labour market to the ageing workforce.
