Walmart Inc.
Walmart is the world's largest private employer, with approximately 2.1 million associates worldwide. The Arkansas-based retail giant operates over 10,500 stores in 19 countries, including Walmart discount stores, Supercenters, Neighborhood Markets, and Sam's Club warehouses. Despite its enormous workforce, Walmart has been investing heavily in automation and self-checkout technology, which has slowed the pace of headcount growth in recent years. The company's massive logistics network is one of the largest private supply chains on Earth.
