# Conventions concerning Wages, Hours of Work on Board Ship and Manning

The Convention concerning Wages, Hours of Work on Board Ship and Manning (or Wages, Hours of Work and Manning (Sea) Convention) is a convention of the International Labour Organization originally drafted in 1946 and revised conventions in 1949 and 1958, none of which entered into force.

## Entry into Force

The criterion of entry into force for all three conventions required a minimum number countries acceding with a significant sea trade volume as well as requirements of the aggregate of trade volume by ratifying countries:
* ratification by nine countries from the group: Argentina, Australia, Belgium, Brazil, Canada, Chile, China, Denmark, Finland, France, Germany (1958 convention only), Greece, India, Ireland, Italy, Japan (1958 convention only), Netherlands, Norway, Poland, Portugal, Spain (1958 convention only), Sweden, Soviet Union (1958 convention only), Turkey, United Kingdom, United States and Yugoslavia;
* ratification from at least five countries with over one million gross register tons of shipping;
* an aggregate tonnage by ratifying countries of more than fifteen million gross register tons.

## Ratifications

An overview of number of ratifications of the conferences is shown below. Although the number of ratifications was larger for the revised conventions, the entry into force criteria were met in none of them. The conventions were closed for signature upon the entry into force of the Seafarers' Hours of Work and the Manning of Ships Convention, 1996.
| year of conclusion | entry into force | ratifications (current) | relevant countries for entry into force | denouncements | closure for signature |
| 1946 | no | 0 | 0 | 0 | 8 August 2002 |
| 1949 | no | 5 | 0 | 0 | 8 August 2002 |
| 1958 | no | 11 | 6 | 4 | 8 August 2002 |
An overview of the ratifications of the conventions as of 27 May 2013 is shown below. Only the 1958 received ratifications from the list of countries of which 9 were required to ratify. Six such ratifications were received (Yugoslavia also ratified, but is depicted in the list as its successor states). Denouncements of the convention were a result of the entry into force of the Seafarers' Hours of Work and the Manning of Ships Convention, 1996 for those countries. Also ratification of the Maritime Labour Convention results -after it enters into force on 20 August 2013- in denouncement of the conventions.
