In the context of the Global Collaboratory on the History of Labour Relations, in this article, we relate the analysis of precarious work in Portugal to the state, in particular, as a direct participant functioning as both employer and mediator. In the second part, we present a short overview of the evolution of casualization in the context of employment and unemployment in contemporary Portugal (1974-2014). In the third section, we discuss state policies on labour relations, particularly in the context of the welfare state. Finally, we compare this present analysis with Swedish research done from the perspective of the state as a direct participant and mediator over the past four decades.
