An underground explosion at Sago Mine in Tallmansville, W. Va., traps 12 miners and cuts power to the mine. Eleven men die, mostly by asphyxiation. The mine had been cited 273 times for safety violations over the prior 23 months - 2006

Thousands of workers began what was to be a two-day strike of the New York City transit system over retirement, pension and wage issues. The strike violated the state’s Taylor Law; TWU Local 100 President Roger Toussaint was jailed for ten days and the union was fined $2.5 million - 2005

Mine, Mill and Smelter Workers union organizer Clinton Jencks, who led New Mexico zinc miners in the strike depicted in the classic 1954 movie “Salt of the Earth,” dies of natural causes in San Diego at age 87 - 2005
