The holiday season is upon us. Sadly, the big retailers are Scrooges when it comes to paying their workers. Undergirding the sale prices is an army of workers earning the minimum wage or a fraction above it, living check to check on their meager pay and benefits. The dark secret that the retail giants like Walmart don't want you to know is that many of these workers subsist below the poverty line, and rely on programs like food stamps and Medicaid just to get by. This holiday season, though, low-wage workers from Walmart to fast-food restaurants are standing up and fighting back. Wal-Mart is the world's largest retailer, with 2.2 million employees, 1.3 million of whom are in the US. It reported close to $120bn in gross profit for 2012. Just six members of the Walton family, whose patriarch, Sam Walton, founded the retail giant, have amassed an estimated combined fortune of between $115bn to $144bn. These six individuals have more wealth than the combined financial assets of the poorest 40% of the US population. Walmart workers have been organizing under the banner of OUR Walmart, a worker initiative supported by the United Food and Commercial Workers union. Workers have taken courageous stands, protesting their employer and engaging in short-term strikes. Walmart has retaliated, firing many who participated. Parallel to the Walmart campaign is a drive for higher wages in the fast-food industry. In more than 100 cities, workers are organizing protests and strikes ... and winning.
