Defense Contractors: Information on Violations of Safety, Health, and Fair Labor Standards [open pdf - 397KB]
From the Document: "The Department of Defense (DOD) is the largest contracting agency in the federal government, obligating more than $380 billion on contracts for goods and services in fiscal year 2019. DOD's contract spending accounted for about 65 percent of the government's total contract spending. Some DOD contracts involve work that can be dangerous, such as manufacturing and construction. The Department of Labor's (Labor) Occupational Safety and Health Administration (OSHA) is the federal agency responsible for overseeing safety and health-related working conditions, and its Wage and Hour Division (WHD) is responsible for enforcing requirements related to minimum wage, overtime pay, and child labor standards. We previously reported that DOD has awarded contracts to some companies that Labor found to have violated federal labor laws, including workplace safety, health, and wage standards."
