Meet the robots inside Amazon's fulfillment centers

Last year, we spent $386 billion on stuff from Amazon – that's half of all our online spending. And the bigger Amazon gets, the more unwelcome attention it gets for its workplace conditions, especially from employees like Jennifer Bates, who testified before a Senate committee:

"My workday feels like a nine-hour intense workout, every day, and they track our every move," she said. Now, Amazon points out that its warehouse workers make over twice the national minimum wage, and get full medical benefits and a company-matched 401(k) plan.
