Abstract
Fundamental shifts in the structure of labour markets, work systems, and employment relations of industrialized countries have outpaced changes in legislative, social and political mechanisms. As a result, a growing number of workers are exposed to precarious employment experiences, which we define as experiences that give rise to instability, lack of protection, insecurity, and social and economic vulnerability. These experiences represent a potentially significant occupational health risk. Our central objective is to develop a detailed framework that outlines the key aspects of work experiences that makes them precarious, and to consider links between these aspects and downstream health effects.
