In the context of increasing job instability, novel forms of workers' solidarity are emerging as alternatives to trade unions in Europe. These phenomena represent a subject of interest, as they have not yet been explored in depth in the existing organizational literature.


The contribution aims to establish a theoretical framework encompassing the concepts of "organised / organizing work solidarity", thereby facilitating a comprehensive understanding of the topic. The aim is to advance the theoretical exploration of work solidarity, by highlighting current discourses surrounding i, and the factors that facilitate or impede its expression.


A Scoping Review was conducted on Scopus, PsychINFO and JSTOR. 27 empirical and theoretical contributions from 2014 to 2024 were selected. A qualitative meta-analysis was conducted, with a focus on the definitions of work solidarity and its organisation, the factors enabling and hindering it, and its impacts.


Four distinct approaches to work solidarity are identified, from which specific impacts are derived: solidarity as collective mobilisation; as the construction of reciprocal and mutual relationships; as the development of collective identities; as help/support for the most vulnerable. The primary targets of solidarity action encompass both the conventional domains protected by trade unions and the emergent non-standard employment categories. A particular focus is placed on marginalised groups, including informal employment and domestic work.
In conclusion, the factors that facilitate or impede solidarity are analysed from a cultural, organisational, relational and individual perspective.


The review is innovative insofar as there is a paucity of recent literature on the subject. This provides a foundation upon which work and organisational psychologists may contemplate their involvement with work solidarity and solidarity organizing
