This paper seeks to bridge the existing knowledge gap between workplace learning and life course studies by investigating how young adults in the retail industry identify, pursue, and actualise learning opportunities in their workplaces. It considers the elements from their life course that either facilitate or impede these learning opportunities. The study contributes to workplace learning and life course studies by constructing a nuanced understanding of young adults' agency in navigating their learning and development within the work context. The research is based on an exploratory single case study of young adults working in the Danish retail sector, specifically in non-specialised food handling. Learning biography vignettes (LBV) serves as the empirical foundation for analysis. The findings highlight the complex interplay between personal life events, social support, work environments, and individual agency in shaping the learning and development trajectories of young adults. The research underscores the need for workplaces to be supportive and flexible, providing a range of learning opportunities. It is vital that these environments recognise individual agency and cater to both the personal and professional growth needs of young adults.
