Wal-Mart pays Mexican teens $0 an hour

The company doesn’t try to conceal this practice: its 62 Superama supermarkets display blue signs with white letters that tell shoppers: OUR VOLUNTEER PACKERS COLLECT NO SALARY, ONLY THE GRATUITY THAT YOU GIVE THEM. SUPERAMA THANKS YOU FOR YOUR UNDERSTANDING. The use of unsalaried youths is legal in Mexico because the kids are said to be “volunteering” their services to Wal-Mart and are therefore not subject to the requirements and regulations that would otherwise apply under the country’s labor laws. But some officials south of the U.S. border nonetheless view the practice as regrettable, if not downright exploitative.
