In 1927, a law was approved by the National Administrative Council of Uruguay that provided for a minimum wage for those employed on public works.

[7] In 1928, a new public charity hospital was built by the government in the town of Lazcano, while the National Council of Administration authorized the Syphilis Prophylaxis Institute (as noted by one study) “to expend 18,000 pesos in the construction of a building in the city of Melo to house the dispensary for that locality.” [8] An executive order made airplanes of the army medical corps available to the general public to use as ambulances in cases of extreme urgency.

According to one study, this represented “an important development of the extensive campaign now in progress for the prophylaxis and cure of this disease in Uruguay.”[10] That same year, a law was passed that established Sunday as a day of mandatory rest for officials and owners of hairdressers and barbershops.

[11]Under a law of 25 June 1930, a minimum wage previously established on 18 November 1926 for port workers was extended to more people.
