A new study published by researchers at the National Institute for Occupational Safety and Health (NIOSH), “Job Characteristics Associated With Self-Rated Fair or Poor Health Among U.S. Workers,” finds that workers employed in business operations jobs, such as marketing or human resource professionals, were more likely to rate their health as fair or poor. The study also found workers who had no paid sick leave, worried about becoming unemployed, had difficulty balancing work and family or who were bullied at work were more likely to report poor health.
