Health disparities among wage workers driven by employment instability in the Republic of Korea.
Even though labor market flexibility continues to be a source of grave concern in terms of employment instability, as evidenced by temporary employment, only a few longitudinal studies have examined the effects of employment instability on the health status of wage workers. Against this backdrop, this study assesses the manner in which changes in employment type affect the health status of wage workers. The data originate from the Korean Labor and Income Panel Study's health-related surveys for the first through fourth years (n = 1,789; 1998 to 2001). This study estimates potential damage to self-rated health through the application of a generalized estimating equation, according to specific levels of employment instability. While controlling for age, socioeconomic position, marital status, health behavior, and access to health care, the study analysis confirms that changes in employment type exert significant and adverse effects on health status for a given year (OR = 1.47; 95% CII 1.10-1.96), to an extent comparable to the marked effects of smoking on human health (OR = 1.47; 95% CI 1.05-2.04). Given the global prevalence of labor flexibility, policy interventions must be implemented if employment instability triggers broad discrepancies not only in social standing, wage, and welfare benefits, but also in health status.
