Walmart, which has a presence in communities of all shapes and sizes, is the largest private employer in the nation with 1.5 million workers. Yet the number of Americans who rely on the corporate giant for their livelihoods is dwarfed by the number who rely on the federal government for their paychecks. The federal government employs nearly 9.1 million workers, comprising nearly 6 percent of total employment in the United States. The figure includes nearly 2.1 million federal employees, 4.1 million contract employees, 1.2 million grant employees, 1.3 million active duty military personnel, and more than 500,000 postal service employees.
