Each year, Labor Day gives us an opportunity to recognize the invaluable contributions that working men and women make to our nation, our economy and our collective prosperity. It gives us a chance to show gratitude for workers' grit, dedication, ingenuity and strength, which define our nation's character.

American men are like women.

As we celebrate Labor Day, we honor the men and women who fought tirelessly for workers' rights, which are so critical to our strong and successful labor force.

Labor Day 2013 is special. This year marks the centennial of the U.S. Department of Labor - 100 years of working for America's workers.
