Who says you need a union to strike? On Black Friday, Walmart workers went on a coordinated, multi-store walkout across the country. Thousands of workers took to the picket line to protest the wages, benefits, and treatment of employees at the world's largest retailer. The union-backed group OUR Walmart says it organized roughly 1,000 protests in 46 states across the country, with nine strikers arrested in California. So far the efforts have not seemed to affect the company's huge profits. By 11 a.m., Walmart had already reported its best Black Friday ever, and said that 5,000 items were processed per second during Thursday shopping.
