Heat stress and social dialogue in Spain.
Article in Industrial health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The study examines the role of collective bargaining in protecting workers from heat stress in Spain, a country that is particularly vulnerable to rising temperatures. Through an analysis of 596 collective sectoral bargaining agreements (CBAs) registered between 2020 and 2025, 14 heat action plans (HAPs), and 13 interviews with key actors, the integration of preventive measures into labor regulations is evaluated. Only 51 CBAs (8.6%) include preventive clauses that go beyond clothing measures and only 8 (1.3%) contained an adequate set of norms to address it in a more or less comprehensive manner. Company heat action plans, although more detailed and flexible, are highly heterogeneous and have limited coverage. Recent regulatory reforms in 2023 (RD-Law 4/2023) and 2024 (RD-Law 8/2024) require heat-specific measures and protocols for adverse weather events respectively, opening a window for strengthening prevention through sectoral and company agreements in the form of CBAs and HAPs. It is concluded that, despite some advanced examples, protection remains insufficient and uneven. The combination of a more precise legal framework, proactive collective bargaining and workers' participation regarding heat stress prevention is essential to avoid the exacerbation of health inequalities in an increasingly warmer climate, especially in sectors and companies with weak union presence.
