Imagine working six days every week and getting only one day off. For many workers in Latin America, that has been normal. Now that may be changing. (apnews.com)

In Brazil, the lower house of Congress approved a constitutional amendment on May 27, 2026. It would cut the legal workweek from 44 hours to 40 hours, spread over five days, with two paid rest days and no pay cut. Brazilian officials say at least 37 million workers could benefit, but the proposal still needs approval from the Senate. (camara.leg.br)

Brazil is part of a bigger regional shift. In Chile, the country’s 40-hour law started on April 26, 2024. Chile first moved from 45 hours to 44 hours, then cut the week again to 42 hours on April 26, 2026. The final step to 40 hours is planned for 2028, and the law says wages should not go down.

Colombia is also moving in that direction. A 2021 law set a gradual path from 48 hours to 42 hours. The next and final step is due on July 15, 2026, and the law also says salaries should not be reduced. (normograma.mincultura.gov.co)

Mexico chose a slower plan. Lawmakers approved the reform in February 2026, and the constitutional change was published on March 3, 2026. Mexico keeps a 48-hour week in 2026, then plans 46 hours in 2027, 44 in 2028, 42 in 2029, and 40 in 2030. (apnews.com)

Supporters say shorter weeks can mean more time for family, more rest, and better productivity. Critics warn about higher costs and possible hiring cuts, especially for smaller businesses. So the six-day week is not gone yet. But across Latin America, the 40-hour week is clearly spreading. (apnews.com)
