A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, GAO found that women, on average, earned 80 percent of what men earned in 2000 and workplace discrimination may be one contributing factor. The Equal Employment Opportunity Commission (EEOC) and the Department of Labor (Labor) enforce several laws intended to prevent gender pay discrimination. GAO examined (1) how EEOC enforces laws addressing gender pay disparities among private sector employers and provides outreach and what is known about its performance, and (2) how Labor enforces laws addressing gender pay disparities among federal contractors and provides outreach and what is known about its performance. GAO analyzed relevant laws, regulations, monitoring reports, and agency enforcement data and conducted interviews at the agencies' central offices and two field offices experienced in gender pay cases."
