C41 Convention concerning Employment of Women during the Night
Geneva, 19 giugno 1934
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 Eighteenth Session on 4 June 1934, and
Having decided upon the adoption of certain proposals with regard to the partial revision of the Convention concerning employment of women during the night adopted by the Conference at its First Session, which is the seventh item on the agenda of the Session, and
Considering that these proposals must take the form of an international Convention,
adopts this nineteenth day of June of the year one thousand nine hundred and thirty-four the following Convention, which may be cited as the Night Work (Women) Convention (Revised), 1934:
1. For the purpose of this Convention, the term industrial undertaking includes particularly--
(a) mines, quarries, and other works for the extraction of minerals from the earth;
(b) industries in which articles are manufactured, altered, cleaned, repaired, ornamented, finished, adapted for sale, broken up or demolished, or in which materials are transformed; including shipbuilding, and the generation, transformation, and transmission of electricity or motive power of any kind;
(c) construction, reconstruction, maintenance, repair, alteration, or demolition of any building, railway, tramway, harbour, dock, pier, canal, inland waterway, road, tunnel, bridge, viaduct, sewer, drain, well, telegraphic or telephonic installation, electrical undertaking, gas work, waterwork or other work of construction, as well as the preparation for or laying the foundations of any such work or structure.
2. The competent authority in each country shall define the line of division which separates industry from commerce and agriculture.
1. For the purpose of this Convention, the term night signifies a period of at least eleven consecutive hours, including the interval between ten o'clock in the evening and five o'clock in the morning.
2. Provided that, where there are exceptional circumstances affecting the workers employed in a particular industry or area, the competent authority may, after consultation with the employers' and workers' organisations concerned, decide that in the case of women employed in that industry or area, the interval between eleven o'clock in the evening and six o'clock in the morning may be substituted for the interval between ten o'clock in the evening and five o'clock in the morning.
3. In those countries where no Government regulation as yet applies to the employment of women in industrial undertakings during the night, the term night may provisionally, and for a maximum period of three years, be declared by the Government to signify a period of only ten hours, including the interval between ten o'clock in the evening and five o'clock in the morning.
Women without distinction of age shall not be employed during the night in any public or private industrial undertaking, or in any branch thereof, other than an undertaking in which only members of the same family are employed.
Article 3 shall not apply--
(a) in cases of force majeure, when in any undertaking there occurs an interruption of work which it was impossible to foresee, and which is not of a recurring character;
(b) in cases where the work has to do with raw materials or materials in course of treatment which are subject to rapid deterioration, when such night work is necessary to preserve the said materials from certain loss.
In India and Siam, the application of Article 3 of this Convention may be suspended by the Government in respect to any industrial undertaking, except factories as defined by the national law. Notice of every such suspension shall be filed with the International Labour Office.
In industrial undertakings which are influenced by the seasons and in all cases where exceptional circumstances demand it, the night period may be reduced to ten hours on sixty days of the year.
In countries where the climate renders work by day particularly trying to the health, the night period may be shorter than prescribed in the above Articles, provided that compensatory rest is accorded during the day.
This Convention does not apply to women holding responsible positions of management who are not ordinarily engaged in manual work.
The formal ratifications of this Convention shall be communicated to the Director-General of the International Labour Office for registration.
1. This Convention shall be binding only upon those Members of the International Labour Organisation whose ratifications have been registered with the Director-General.
2. It shall come into force twelve months after the date on which the ratifications of two Members have been registered with the Director-General.
3. Thereafter, this Convention shall come into force for any Member twelve months after the date on which its ratification has been registered.
As soon as the ratifications of two Members of the International Labour Organisation have been registered with the International Labour Office, the Director-General of the International Labour Office shall so notify all the Members of the International Labour Organisation. He shall likewise notify them of the registration of ratifications which may be communicated subsequently by other Members of the Organisation.
1. A Member which has ratified this Convention may denounce it after the expiration of ten years from the date on which the Convention first comes into force, by an act communicated to the Director-General of the International Labour Office for registration. Such denunciation shall not take effect until one year after the date on which it is registered with the International Labour Office.
2. Each Member which has ratified this Convention and which does not, within the year following the expiration of the period of ten years mentioned in the preceding paragraph, exercise the right of denunciation provided for in this Article, will be bound for another period of ten years and, thereafter, may denounce this Convention at the expiration of each period of ten years under the terms provided for in this Article.
At such times as it may consider necessary the Governing Body of the International Labour Office shall present to the General Conference a report on the working of this Convention and shall consider the desirability of placing on the agenda of the Conference the question of its revision in whole or in part.
1. Should the Conference adopt a new Convention revising this Convention in whole or in part, then unless the new Convention otherwise provides,
(a) the ratification by a Member of the new revising Convention shall ipso jure involve the immediate denunciation of this Convention, notwithstanding the provisions of Article 12 above, if and when the new revising Convention shall have come into force;
(b) as from the date when the new revising Convention comes into force, this Convention shall cease to be open to ratification by the Members.
2. This Convention shall in any case remain in force in its actual form and content for those Members which have ratified it but have not ratified the revising Convention.
The French and English texts of this Convention shall both be authentic.
