C63 - Convention concerning Statistics of Wages and Hours of Work, 1938

 (Entry into force: 22 Jun 1940)

Adoption: Geneva, 24th ILC session (20 Jun 1938).

[Abrogated Convention - By decision of the International Labour Conference at its 112th Session (2024)]

Preamble

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 Twenty-fourth Session on 2 June 1938, and

Having decided upon the adoption of certain proposals with regard to statistics of wages and hours of work in the principal mining and manufacturing industries, including building and construction, and in agriculture, which is the sixth item on the agenda of the Session, and

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

Having determined that, although it is desirable that all Members of the Organisation should compile statistics of average earnings and of hours actually worked which comply with the requirements of Part II of this Convention, it is nevertheless expedient that the Convention should be open to ratification by Members which are not in a position to comply with the requirements of that Part,

adopts this twentieth day of June of the year one thousand nine hundred and thirty-eight the following Convention, which may be cited as the Convention concerning Statistics of Wages and Hours of Work, 1938:

Preamble

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 Twenty-third Session on 3 June 1937, and

Having decided upon the adoption of certain proposals with regard to safety provisions for workers in the building industry with reference to scaffolding and hoisting machinery, which is the first item on the agenda of the Session, and

Considering that, in view of the desirability of standardising minimum safety provisions without prescribing requirements too rigid for general application, the most appropriate form for these proposals is that of an international Convention accompanied by a Recommendation embodying a model code of safety regulations,

adopts this twenty-third day of June of the year one thousand nine hundred and thirty-seven the following Convention, which may be cited as the Safety Provisions (Building) Convention, 1937:
