Today (June 17 2014) an amendment to Section III of Article 123 of the Constitution was published in the Official Federal Gazette to set the legal working age to fifteen years of age instead of fourteen, as it had been since 1917. This provision, which will come into force tomorrow, aligns with the standards of the International Labor Organization (ILO), especially agreement 138 of said organization. Mexico has still not ratified this agreement, which has caused ILO to issue a couple of recommendations for Mexico.
The Organization has expressed its position on child labor in several fora stating that it deprives children of their dignity and that it impairs their physical and psychological development. With several studies it has been concluded that the benefits of eliminating child labor outweigh its cost by a factor of seven.
