In the current era of austerity free movement of labour has produced an ongoing but also contingent flow of migrant labour, an austeriat, moving from poorer crisis-hit regions of Europe to those countries such as Sweden where the crisis has been less severe. This article describes the working and living experiences of Bulgarian Roma berry pickers in Sweden. It argues that, in the context of a previously well-regulated labour market, an erosion of labour standards based on the exploitation of seasonal unskilled labour migrants from Bulgaria is occurring in the Swedish berry industry, in turn posing challenges for labour market actors and regulatory authorities. The article concludes with a discussion of what might be appropriate European and national trade union responses to the issues of labour precariousness which have emerged.
