This dissertation focuses on explaining and improving Central and Eastern European migrant workers’ quality of working conditions in the greenhouse-horticulture and warehousing sectors in the Netherlands. Migrant workers’ precarious quality of working conditions is a persistent policy challenge in the increasingly flexible Dutch labour market (Cremers, 2023; Siegmann et al., 2022). Precarious work makes migrants’ working lives insecure, unstable and uncertain, pushes the responsibility of the risks of the work to migrants, limits their capacity to voice their concerns, provides them with minimal social protection, and subjects them to inequal and unfair treatment at the workplace (Allan et al., 2021; Kalleberg & Vallas, 2018). Since the enlargement of the European Union (EU) in 2004, 2011 and 2013, Central and Eastern European (CEE) workers have grown to make up one of the largest migrant groups in the Netherlands (CBS, 2024). Enticing, migrant-targeted advertisement of work opportunities and cross-border hiring in historically precarious, low-wage industries has contributed to the growth of the CEE migrant worker group, specifically in the Dutch greenhouse horticulture and warehousing sectors (Acocella et al., 2024; Kroon & Paauwe, 2014; Pijpers, 2010; Siegmann et al., 2022). The dissertation focuses on (1) identifying the underlying factors that explain the quality of working conditions for CEE migrant workers (Chapter 2, 3); (2) exploring how CEE migrant workers experience their quality of working conditions (Chapter 4, 5, 6); (3) and identifying measures that institutions, organizations and migrant workers can take to contribute to improving the quality of work in the Dutch greenhouse horticulture and warehousing sectors (Chapter 7). The findings of this dissertation point to the role of stakeholders in improving migrants’ quality of working conditions. In particular, this dissertation shows that stakeholders at the institutional(government, non-governmental organizations, trade unions, employers organizations and media representatives), organizational (temporary work agencies and user organization) and workerlevels (migrant workers) need to engage in action to achieve better quality of working conditions for migrant workers. This dissertation adopts an interdisciplinary approach, integrates cross-level analysis, critically assesses the role of the researcher .
