Protecting Labor Rights Amid the Climate Crisis: Heat Stress and Occupational Safety

• Extreme heat driven by the climate crisis poses a major public health threat and significantly degrades occupational safety.
• Statistics from Spain show a sharp rise in heat-related deaths and a 17.4% increase in workplace accidents during heatwaves.
• Employers are legally responsible for identifying risks, implementing preventive measures, and ensuring worker safety in extreme temperatures.

Risks in the Workplace

• Workers in outdoor sectors like construction and agriculture, as well as indoor environments like foundries and bakeries, face high risks of heat stress.
• Complications from heat exposure include dehydration, muscle cramps, dizziness, and fatal heatstroke.
• Vulnerability is intensified by chronic conditions, physical exertion levels, and inadequate protective equipment.

Regulatory Framework

• Current Spanish labor law (LPRL) and Real Decreto 486/1997 mandate specific temperature ranges (14–27°C) for workspaces to prevent health risks.
• Employers must provide training, establish hydration protocols, plan for acclimatization, and provide shaded or cooled break areas.
• A 2024 royal decree mandates collective bargaining for protocols against adverse weather and introduces paid leave during extreme events.

Implementation Gaps and Advocacy

• Labor unions, including UGT and CCOO, report that only 10% of companies have effective action plans for climate-related hazards.
• The "Aprender sin Calor" platform highlights the inadequacy of school facilities, calling for "climate shelters"—including tree planting, solar energy for cooling, and water fountains—to protect students and staff.
• Unions argue that the failure to protect workers is systemic, labeling the crisis a consequence of an economic model that prioritizes fossil fuel profits over human life.
