While atypical employment contracts offer flexibility in the labor market, these kinds of contracts are inherently insecure and may generate stress among affected workers. This study examines the impact of atypical forms of employment (specifically seasonal or temporary jobs or a fixed time contracts) on workers' health. Survival analysis shows that, other things equal, the longer percent of time spent in flexible employment contracts increases the odds of falling into ill health for a variety of health conditions. The results are robust to controlling for the endogeneity in the relationship.
