Objectives The review is part of the Sweden-based research programme PWR, which consists of early-career and senior researchers in public health, occupational health as well as social sciences from a range of European countries, the United States, Canada and Chile. PWR started in 2019. The purpose of our review is to identify implemented initiatives that aim to or have the potential to eliminate, reduce or mitigate workers’ exposure to precarious employment and/or its effects on the physical and mental health, health equity, safety and well-being of workers.

Methods We use the PRISMA guideline for systematic reviews, including its extension for equity-focused reviews. Our comprehensive search covers a combination of social, public health, medical, and public policy databases along with relevant sources of grey literature. Inclusion criteria: 1. All evaluated initiatives: successful, unsuccessful, and inconclusive; 2. Initiatives implemented in any region, sub-region, or country, etc. no matter the level of economic development or government unit level; 3. Initiatives targeting at micro, meso, or macro-level, within or outside the realm of precarious employment; 4. Reports and peer-reviewed primary studies with a qualitative, quantitative, or mixed-methods design; 5. English, Catalan, Danish, Dutch, French, Italian, Norwegian, Romanian, Spanish or Swedish language studies.

Results Our results will be grouped according to the specific outcomes targeted by interventions, such as health, well-being, health equity, work environment conditions and characteristics, access to social security services or benefits, and worker skills. Conclusions

By sharing our intermediate findings, we hope to get feedback from key stakeholders and learn of interventions that we may have missed through the literature search. Given the increase in precarious work in both highly-developed and developing countries, we have to strengthen and diversify our efforts to address such challenges.
