Abstract: Taking note of the polysemic and controversial nature of the concept "social dialogue", this issue revisits what it covers in practices, according to the contexts (institutional, territorial, economic...) in which it is implemented. This update seems all the more necessary as the institutional and economic environment has changed significantly over the last decade. The articles that constitute this issue have in common that they deal with "social dialogue" mainly in the context of the firm, by questioning the capacities and modalities of action of employee representatives at this level. In doing so, they all show the relevance and the necessity of understanding industrial relations - in the diversity of practices - "in context", i.e. in relation to socio-productive configurations, modes of governance and sectoral specificities.
