Teresa, an immigrant from Mexico has worked at a pork processing plant in Lincoln, Neb., since 2011. She didn't want to use her last name because she feared that a family member, who still works at a plant, might get in trouble.
Teresa worked on the line, or "the chain," as workers call it. It is the heartbeat of any meat processing plant. It's the mechanized driver of eviscerated hogs, cattle and chickens, hung up on hooks and quickly moving down a line at these massive meat factories.
