The purpose of this research synthesis is to map common themes related to learning of workers aged 50+ in knowledgeintensive professions. The research questions focus on identifying (1) the typical features of learning for senior knowledge workers and (2) what kind of organisational conditions encourage senior knowledge workers to continue learning and contributing to their work community. The techniques of qualitative research synthesis are applied in order to make sense of themes and concepts that have recurred across individual qualitative studies conducted by the group of graduate students at University of Helsinki, Finland, between 2012 and 2015. The findings indicate that self-regulation, continuity, sharing and networking are typical for learning at age 50+. The organisational conditions that enable and support such learning during the late professional career include three main things: senior knowledge workers are involved in and can influence organisational changes; they are actively participating in multi-aged collaboration and they enjoy appreciation of the organisational management.
