"This study examines the role of trade unions and social dialogue in shaping the Italian prevention system for occupational health and safety (OHS) risks associated with heatwaves. Drawing on the European project Adaptheat, it addresses a research gap on the short-term impacts of climate change on the workforce and the interventions of social actors to address them. The methodology combined literature review, documentary analysis, and qualitative interviews with different stakeholders, including workers, in Apulian agriculture and in logistics warehouses. Findings show that trade unions have been pivotal in translating scientific evidence—particularly from the Worklimate project—into institutional measures and into collective bargaining agreements. Despite regulatory progress, the system relies mainly on regional ordinances, resulting in fragmented and reactive prevention rather than integrated and proactive planning. Compared with international benchmarks, the Italian case underscores the need to strengthen the regulatory framework, linking heatwave-related OHS protection with broader labour and social rights."
