This report, based on 42 interviews with workers, trade unionists and other stakeholders, examines the phenomena of low-paid and precarious work in Sheffield. It focuses on the factors driving the prevalence of such work (including the links with welfare reform), the experiences of workers in seven distinct employment sectors, as well as trade union responses to the challenges of organising in these areas. The report also includes a major addition of a postscript focused on the impacts of the Coronavirus pandemic and how this relates to the wider findings of the study.
