Outside of the U.S. Embassy in Bogota, Colombia, 13 former General Motors Company (NYSE: GM) employees are staging a hunger strike protest charging worker mistreatment by the company, and seven of those men have sewn their mouths shut. One man, Manuel Ospina Contreras, 42, was admitted to the hospital over the weekend and is considered by his doctor to be malnourished, dehydrated and at risk of heart attack. The hunger strike is in its fourth week.
