Today in Labor History April 5, 2010: Twenty-nine coal miners were killed in an explosion at the Upper Big Branch Mine in West Virginia. In 2015, Former Massey Energy CEO Don Blankenship was convicted of a misdemeanor for conspiring to willfully violate safety standards and was sentenced to one year in prison. He was found not guilty of charges of securities fraud and making false statements. Investigators also found that the U.S. Department of Labor and its Mine Safety and Health Administration were guilty of failing to act decisively, even after Massey was issued 515 citations for safety violations at the Upper Big Branch mine in 2009, prior to the deadly explosion.
