Work and health are inextricably linked. Most American adults spend nearly half of their waking hours at work. Poor physical and social working conditions are associated with chronic illnesses such as hypertension, and work-related accidents and illnesses claim billions of dollars in health care costs and lost productivity annually. Racial and ethnic minorities disproportionately work in low-paying jobs and face increased risks of work-related injury or disability. Policies and benefits such as paid sick leave and unemployment compensation are associated with improved health outcomes. Employment is also the source for most nonelderly Americans' health insurance coverage. Some companies promote healthy lifestyle choices through wellness and other programs, understanding that healthy, productive workers contribute positively to the bottom line.
