Since 1997 controversy has surrounded Korean factories of Cort and Cor-Tek due to its alleged mistreatment of factory workers. Grievances include the closing of its Daejon factory with no advance warning on April 9, 2007, mass redundancies of all staff from its Incheon plant on April 12, 2007, and the firing and mistreatment of union officials and members.On July 12, 2007 a Cort worker set himself on fire in protest, and on October 15, 2008 workers conducted a 30-day hunger strike and sit-in occupation on a 40-meter electricity tower. Rage Against the Machine guitarist Tom Morello and System Of A Down frontman Serj Tankian - both partners in the Axis Of Justice - joined representatives of the Cort workers in a protest concert against Cort and Cor-tek on January 13, 2010 at the Nanum Cultural Center in Los Angeles. Morello said "I fully support the Korean workers' demands for justice in the workplace. All American guitar manufacturers and the people that play them should hold Cort accountable for the awful way they have treated their workers."This controversy went through various legal stages in Korea from 2007 through 2012. Ultimately, Cort received favorable decisions from the Supreme Court in Korea that ended any further liability on Cort's part to the terminated employees. The court recognized that the closure of the plant in 2008 and subsequent layoff were justified.
