This project aims to explore the relationship between insecure employment and mental health by applying advanced econometric methods to large administrative datasets and newly collected survey data. This is expected to provide causal policy-relevant estimates of how job and economic insecurity is affecting the mental health of workers and their families, and for whom the effects are most harmful. It is also expected to inform on how mental health influences the types of jobs that people enter into. This research should provide significant benefits, including the evidence needed to improve existing workplace programs and policies, and to ensure that assistance is efficiently targeted to those workers and industries with the greatest need
