The meaning of the terms precarious work and vulnerable workers

This paper is a work in progress. Our research questions include the issue of whether the two terms are inextricably linked. Are those in precarious work more likely to be vulnerable workers? Are vulnerable workers more likely to be in precarious work than others? Are workers made vulnerable by being in precarious work? Our first step is clearly to understand what is meant by these two terms in the work context and perhaps to further refine any definitions
