A new report says that Walmart's cost cutting measures in its supply chain have led to lower wages and benefits for warehouse workers across the country. The company outsources its warehouses and transportation to third parties, who often use temporary workers. The practice has led others to adopt it in their own warehouses, leading to lower wages and benefits for workers. The study also found that Walmart's use of subcontractors was an effective way of insulating them from risks and laws associated with employing those workers.
