The International Labour Organization (ILO) is a United Nations agency dealing with labour issues. It was established in 1919 after World War I to promote social justice and decent work. The ILO registers complaints against entities violating international labour standards but does not impose sanctions. It has three main governing bodies - the International Labour Conference, Governing Body, and International Labour Office. The ILO's objectives include full employment, social security, occupational safety, child welfare, education, and setting international labour standards. Its major activities include employment promotion, improving working conditions, hours of work, paid holidays, and appropriate wages.
