Heat stress and social dialogue in Greece.

This paper explores the current landscape of collective bargaining agreements in Greece, alongside the broader legislative framework governing occupational heat stress. The findings reveal that the existing framework regulating occupational heat exposure remains general and insufficient. The specific circulars on heat stress prevention do not carry the same legal weight as laws or presidential decrees. Therefore, the adoption of dedicated legislation addressing occupational heat stress is considered essential. Effective protection requires the implementation of preventive measures across all sectors, for all categories of workers, and throughout all periods-not only during officially declared heatwaves. Labour inspectorate workplace inspections should be intensified, as implementation legislation remains limited. Heat stress provisions are rarely included in collective bargaining agreements. The weakening of collective bargaining following the economic crisis has contributed to this gap. The role of trade unions and workers' occupational safety and health (OSH) representatives is critical in strengthening collective bargaining and safeguarding workers from occupational risks. To improve heat stress management, the study highlights the need for expanded awareness-raising initiatives, sector-specific training, enhanced understanding and use of the Wet Bulb Globe Temperature (WBGT) index, systematic recording of worker morbidity and mortality, and strengthened research efforts on heat stress prevention.
