The Globe and Mail reports in its Friday edition that Amazon workers at seven U.S. facilities walked off the job early Thursday as workers protest what they say is the retailing giant's unfair treatment of its employees. A Reuters dispatch to The Globe says that warehouse workers in cities, including New York, Atlanta and San Francisco, were taking part in what Teamsters officials called the largest-ever strike against Amazon, but which may cause barely a ripple in the company's operations. As the world's second-largest private employer after Walmart, Amazon has long been a target for unions that say the company's emphasis on ever-faster speed and efficiency can lead to injuries. The company says it pays industry-leading wages and uses automation designed to reduce repetitive stress. Workers told Reuters they want Amazon to come to the bargaining table and recognize the pressure to meet demands that affect their health. However, the strikers represent a small number of the 800,000-plus people employed by Amazon at over 600 U.S. fulfilment centres. Jordan Soreff, 63, who delivers about 300 packages a day for Amazon in the New York boroughs of Queens and Brooklyn, said, "The more you do, the more you're expected to do."
