A new study by researchers at McGill University found that temporary employees show more signs of depression, which hurts not only their productivity but the company as whole.... This is especially troubling because, as the recession softens, economists predict employers will hire temp workers before full-time employees. But for someone new to the workforce, or just desperate for a job, temporary employment can seem like a viable option... It means guaranteed hours for a set amount of time.

Using data from the U.S. National Survey of Youth between 1992 and 2002, researchers identified that temp employees, on average, suffered from two additional signs of depression than regular workers. And employees who continued to work temp jobs four years after initially being surveyed were even more likely to become depressed, leading researchers
