Work time reduction via a 4-day workweek finds improvements in workers' well-being.
Article in Nature human behaviour, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Time spent on the job is a fundamental aspect of working conditions that influences many facets of individuals' lives. Here we study how an organization-wide 4-day workweek intervention-with no reduction in pay-affects workers' well-being. Organizations undergo pre-trial work reorganization to improve efficiency and collaboration, followed by a 6-month trial. Analysis of pre- and post-trial data from 2,896 employees across 141 organizations in Australia, Canada, Ireland, New Zealand, the UK and the USA shows improvements in burnout, job satisfaction, mental health and physical health-a pattern not observed in 12 control companies. Both company-level and individual-level reductions in hours are correlated with well-being gains, with larger individual-level (but not company-level) reductions associated with greater improvements in well-being. Three key factors mediate the relationship: improved self-reported work ability, reduced sleep problems and decreased fatigue. The results indicate that income-preserving 4-day workweeks are an effective organizational intervention for enhancing workers' well-being.
