The fundamental principles and rights at work are derived from the ILO Constitution and the Declaration of Philadelphia. The fundamental principles and rights are laid down in eight fundamental Conventions, which means that the member States that ratify them thereby commit themselves to putting their provisions into effect in both law and practice:
(a) Freedom of association and the right to collective bargaining: Freedom of Association and Protection of the Right to Organize Convention, 1948 (No. 87) and Right to Organize and Collective Bargaining Convention, 1949 (No. 98);
(b) Elimination of forced or compulsory labour: Forced Labour Convention, 1930 (No. 29) and Abolition of Forced Labour Convention, 1957 (No. 105);
(c) Abolition of child labour: Minimum Age Convention, 1973 (No. 138) and Worst Forms of Child Labour Convention, 1999 (No. 182); and
(d) Elimination of discrimination in respect of employment and occupation: Equal Remuneration Convention, 1951 (No. 100) and Discrimination (Employment and Occupation) Convention, 1958 (No. 111).
