Although the CPA enforced a 1987 law banning unions in public enterprises, trade unions such as the Iraqi Federation of Trade Unions (IFTU) and Iraq's Union of the Unemployed have also mounted effective opposition to the Coalition. However, no trades unions support the armed insurgents, and unions have themselves been subject to attacks from the insurgents. Hadi Saleh of the IFTU was assassinated under circumstances that pointed to a Ba'athist insurgent group on 3 January 2005. Another union federation, the General Union of Oil Employees (GUOE) opposes the Coalition forces in Iraq and calls for immediate withdrawal but was neutral on participation in the election. Whereas the GUOE wants all Coalition troops out immediately, both the IFTU and the Workers Councils' call for replacement of U.S. and British forces with neutral forces from the UN, the Arab League and other nations as a transition.
