After Walmart, Amazon is now the second largest employer in the United States, GeekWire reports. “Amazon’s headcount grew 77 percent over this time last year, and a big reason for that is the completion of Amazon’s blockbuster deal to buy Whole Foods Market for $13.7 billion and the acquisition of e-commerce company Souq,” it writes. In total, the tech giant now employs about 540,000 U.S. employees.
