One spring day in Wisconsin last year, as a bustling crowd of Madison teachers got ready to march on the Capitol to protest Governor Scott Walker's bill to dismantle public sector unions, the march was led by an unusual team -- a group of African Americans wearing dark shades, snazzy berets, blue uniforms, and taps on their shoes. They were the International Longshore and Warehouse Union's drill team, all the way from California showing their support for Wisconsin's working families. The tradition dates back to the union's founding in the 1930s.
