This article examines the ongoing efforts of trade unions in Ireland to protect and improve the working conditions of personal care workers amid employment and social policy regimes associated with a liberal welfare state. Comparatively low public expenditure on care and the increasing marketisation of care services have undermined the provision of decent work. This article assesses two major union campaigns related to personal care workers over two decades, and reviews the key priorities that have emerged for unions during the COVID-19 pandemic. We consider whether the outcomes of these campaigns have been converted into enhanced rewards for workers and discuss the continuing challenges for union campaigning.
