 Workers at Samsung, one of the largest manufacturers in the world, walked off the job today. They're on a three-day strike, and their union says it's ready to take further action if the South Korean tech giant doesn't meet demands. It's the first time workers have gone on strike at the company. To learn more, we called up Jeffrey Kane. He's the author of Samsung Rising, Inside the Secretive Company Conquering Tech. Jeff, this is just a relatively small portion of workers at Samsung who walked off the job. Why are they going on strike?
