"It was the labor movement that helped secure so much of what we take for granted today. (Applause.) The 40-hour work week, the minimum wage, family leave, health insurance, Social Security, Medicare, retirement plans. The cornerstones of the middle-class security all bear the union label. (Applause.)" President Obama, Labor Day 2010.
