In the aftermath of Hurricane Katrina in September 2005, Walmart used its logistics network to organize a rapid response to the disaster, donating $20 million, 1,500 truckloads of merchandise, food for 100,000 meals, and the promise of a job for every one of its displaced workers.[46] An independent study by Steven Horwitz of St. Lawrence University found that Walmart, The Home Depot, and Lowe's made use of their local knowledge about supply chains, infrastructure, decision makers and other resources to provide emergency supplies and reopen stores well before the Federal Emergency Management Agency (FEMA) began its response.[47] While the company was overall lauded for its quick response amidst criticism of FEMA, several critics were quick to point out that there still remained issues with the company's labor relations.[48]
