They were about twice more likely to report physical health that was less than very good or excellent than workers who expressed feelings of job security at both interviews. Private-sector workers were more vulnerable to the negative health effects of job insecurity than public-sector workers. Job insecurity was especially hard on the well-being of black workers. Black workers who felt constantly insecure about their jobs were nearly three times as likely as insecure whites and more than four times as likely as secure whites to report very high levels of depressive symptoms. The findings suggest that there may be worker health repercussions as the result of current trends in the U. S. labor market, such as outsourcing, downsizing and the increase in nonstandard jobs with reduced hours and benefits.
