ABSTRACT This article examines attempts by UNISON to embed a culture of learning within the workplace. The analysis, which is rooted in resource‐based mobilisation theory, shows how UNISON was able to draw on the Union Learning Fund to create new resources in the form of project workers. These project workers subsequently played a vital role in building support for learning at regional and branch levels. The article also examines ways in which UNISON activists were able to progress the learning agenda through proactive engagement with ‘opportunity structures’.
