Brazil’s Senate voted 75 to 1 on 14 October to end the 6×1 work week, sending a shorter week and two paid rest days to promulgation 11 days before the presidential runoff.
Brazil’s Senate on Wednesday, 14 October, passed the constitutional amendment that ends the 6×1 work week, in which millions of employees work six days and rest one. The vote was 75 to 1 in both rounds, far above the 49 of 81 needed.
For US readers, the vote reshapes labour costs in Latin America’s largest economy and removes one divisive issue from the 25 October runoff. It also affects every American company that employs staff in Brazil.
The text is PEC 221/2019, known in Brazil as a PEC (proposta de emenda à Constituição), or constitutional amendment. It lowers the maximum working week from 44 hours to 42 hours two months after promulgation and to 40 hours a year later, according to Agência Senado and Gazeta do Povo. It also raises weekly paid rest from one day to two, with one of them preferably on a Sunday.
Agência Senado, the Senate’s own news service, reports that daily work is capped at eight hours, with room to offset hours between days. It also says pay may not fall and that some changes will be phased in.
The Chamber of Deputies approved the text in May, and the Senate’s Constitution and Justice Committee (CCJ) cleared it on 2 September. The full Senate held five discussion sessions before the first round, then dispensed with the three sessions normally required before the second.
Hamilton Mourão of the Republicans, a senator for Rio Grande do Sul, cast the only vote against in both rounds. Senate President Davi Alcolumbre told the chamber that millions of Brazilians were following the session with hope.
The vote came 11 days before the runoff between President Luiz Inácio Lula da Silva and the Liberal Party’s Flávio Bolsonaro on Sunday, 25 October. Lula made ending 6×1 a central promise of his campaign, according to Gazeta do Povo.
Flávio, a Rio de Janeiro senator, said on Tuesday, 13 October, that he would vote for the change after earlier calling it runoff.
Alcolumbre had What It Means for US Readers
Investors in New York-listed Brazilian shares such as Petrobras, Vale and Itaú Unibanco will watch how employers absorb the cost, and the two-step phase-in will decide how quickly it shows up. The result also removes a populist flashpoint from a runoff that will set Brazil’s tone toward the Trump administration.
What Prediction Markets Say
Bettors on Polymarket gave Flávio Bolsonaro 83.0% and Lula 16.5% to win the runoff on 15 October at 12:51 a.m. ET, with about US$182 million traded on the market. That is down from 86.1% for Flávio on 14 October at 4:50 a.m. UTC, though we cannot tie the move to the Senate vote.
Kalshi, regulated in the US by the Commodity Futures Trading Commission (CFTC), priced Flávio at 84.0% and Lula at 18.0% at the same time. These are bets, not polls, and the two sides can add up to more than 100% because of buying and selling spreads.

What Is Not Known
The exact dates depend on when Congress promulgates the amendment, which has not happened yet. Reports do not say how the new rules will apply to shift-based sectors.
No verified estimate of the cost to employers is available. Flávio’s call for hourly flexibility could still resurface in later legislation.
What Comes Next
Congress, not the president, promulgates constitutional amendments, and Gazeta do Povo reports that Alcolumbre indicated this could happen next week. The date has not been fixed.
