The General Conference of the International Labour Organisation,

Having been convened at Geneva by the Governing Body of the International Labour Office, and having met in its Thirty-fourth Session on 6 June 1951, and

Having decided upon the adoption of certain proposals with regard to the principle of equal remuneration for men and women workers for work of equal value, which is the seventh item on the agenda of the session, and

Having determined that these proposals shall take the form of an international Convention,

adopts the twenty-ninth day of June of the year one thousand nine hundred and fifty-one, the following Convention, which may be cited as the Equal Remuneration Convention, 1951:

Article 1

For the purpose of this Convention

1. the term remuneration includes the ordinary, basic or minimum wage or salary and any additional emoluments whatsoever payable directly or indirectly, whether in cash or in kind, by the employer to the worker and arising out of the worker's employment;
2. the term equal remuneration for men and women workers for work of equal value refers to rates of remuneration established without discrimination based on sex.

Article 2

2. This principle may be applied by means of
   1. national laws or regulations;
   2. legally established or recognised machinery for wage determination;
   3. collective agreements between employers and workers; or

Article 3
