Supermarket chain Walmart rewards its managers with record salaries, but its frontline workers still suffer from poor working conditions and low pay. The company's CEO, John Furner, announced last February that he will increase their salaries.

His positions will become one of the highest paid in the country and will be remunerated with company shares. Walmart is the company that most employs people enrolled in low-income US government subsidy programs, such as Medicaid and the Supplemental Nutrition Assistance Program (SNAP), which provides food aid.
