In 1893 , the ITU struck Harrison Gray Otis 's '' Los Angeles Times . '' In 1896 , the union began a boycott that ran until 1908 . In 1903 , ITU President James M. Lynch , persuaded William Randolph Hearst to start a rival paper , the '' Los Angeles Examiner . '' On October 1 , 1910 , James B. Mc Namara , an ITU member and his brother . Joseph J. Mc Namara , secretary-treasurer of the International Union of Bridge and Structural Iron Workers placed a bomb in the L.A. Times building , killing 21 people . Famed attorney Clarence Darrow defended the brothers . They were convicted of the bombing and murder . Despite various job actions that lasted into the 1920s , the '' L.A. Times '' remained a non-union shop . This was a major defeat for both the ITU and other trade unions ; Los Angeles and Southern California would be lost to trade unions except in the case of the entertainment industry
