Abstract
This chapter addresses two key questions: When and in what context in the formative and working lives of leading unionists did ‘nature’ and ‘the environment’ become part of their worldview? How, as a consequence, has their engagement with the environment and their worldview influenced their thinking about the relationship between the environment and labour, and how has this, in turn, influenced their strategy, policymaking and leadership within their respective unions? Life-history interviews of 5 of the 20 unionists interviewed in the UK are discussed in depth to answer these questions. Because environmental concerns are an integral part of their socialist worldview, their analyses of environmental issues are intersectional and integrated with beliefs about justice and equality, and part of an advocacy for ground-up participatory approaches to transformational change.
