# Exploring the health and well-being benefits of reduced working hours with maintained salary: A scoping review and evidence map

## TL;DR

Reducing working hours without lowering pay may improve health and work-life balance, but women often take on more unpaid work.

## Contribution

A scoping review and evidence map of reduced working hours with maintained salary effects on health and gender roles.

## Key findings

- Most studies showed improved work-life balance, mental health, and general well-being with reduced working hours.
- Women often took on more caregiving and household tasks, reinforcing traditional gender roles.
- Evidence suggests benefits from 30–35 hour workweeks, but more research is needed on long-term and sector-specific effects.

## Abstract

The aim of this review was to map the characteristics and the effects of interventions that reduce working hours with full pay maintained on workers’ health, well-being and work–life balance and to assess whether a gender perspective was incorporated.

A scoping review was conducted following PRISMA-ScR and JBI guidelines. Scientific databases (PubMed, Scopus, Web of Science, PsycINFO, CINAHL, Cochrane, ProQuest, Epistemonikos) and grey literature sources (international, European and national labor and occupational health agencies) were systematically searched for studies published between April 2014 and May 2025 in English or Spanish. Eligible studies comprised employed adults in Scandinavian and Western European countries, the United States, Canada, Australia and New Zealand exposed to interventions reducing working hours with full pay maintained. Screening, data extraction, and quality appraisal were conducted independently. An evidence map was developed to synthesize the findings.

Ten scientific articles and five grey literature reports were included, seven from Scandinavian, seven from Western European countries, and one that included both regions. Working time reductions ranged from 10–25%. Most studies reported positive effects on work–life balance (100%), mental health (81.8%), and general health and well-being (58.3%). Qualitative data confirmed improvements in recovery, fatigue, and family time. Eleven studies included a gender perspective, with eight providing stratified analyses. Several studies indicated that women increased the time dedicated to caregiving and household, reinforcing traditional roles, while men’s involvement rose slightly without shifting responsibility equity.

Despite heterogeneity of interventions and limited implementation contexts, it seems that reducing working hours to around 30–35 per week without pay loss may improve work–life balance, health, and well-being. Gender differences emerged, with women often facing increased unpaid work. As the evidence is still scarce particularly regarding long-term effects, sector-specific interventions, and gendered effects, further research is needed to inform and evaluate policies that promote equitable and sustainable work-time arrangements.
