Brazil’s Senate is preparing to debate a constitutional amendment that would end the country’s so-called 6x1 work schedule: six days on the job followed by one day off. The proposal, already approved by the Chamber of Deputies in two rounds of voting, would lower the maximum workweek from 44 to 40 hours without cutting pay.
The bill has become one of Brasília’s most visible labor debates of 2026. It pits a broad argument about quality of life against concerns from employers, economists and some senators that a shorter week could raise labor costs in sectors that depend heavily on hourly staff.
What the Text Says
Under the version approved by the lower house, workers covered by Brazil’s CLT labor code would be entitled to two paid rest days per week, preferably including Sunday. The change would begin 60 days after promulgation, when the maximum workweek would fall to 42 hours.
After another 12 months, completing a 14-month transition, the limit would fall to 40 hours. During the transition, collective agreements could allow companies to adjust daily hours to meet the weekly cap.
The proposal was reported in the Chamber by Deputy Leo Prates of Republicanos, a center-right party. It replaced earlier proposals that would have gone further, including a 36-hour week and, in one version, a four-day workweek.
In the Senate, the amendment must pass two rounds of debate and voting. If senators approve the Chamber text unchanged, Congress can promulgate it. If they alter it, the proposal returns to the Chamber, delaying implementation.
The Economic Divide
Folha de S.Paulo reports that studies cited in the debate point in different directions. Brazil’s National Confederation of Industry (CNI) and the Brazilian Institute of Economics at Fundação Getulio Vargas (FGV-Ibre) warn that reducing hours without productivity gains could lower potential output, especially because Brazil’s labor productivity has been nearly stagnant for decades.
Other research is less pessimistic. A study by Ipea, Brazil’s applied economic research institute, estimated that the measure would raise labor costs by 7.84%, a level it said the economy could absorb without a major effect on gross domestic product. Researchers at the University of Campinas argued that losses are not automatic, since part of the change could be offset by productivity gains, training and better organization of unpaid care work.
Inflation is also disputed. Construction industry group CBIC estimates labor costs could rise by up to 15% in the sector and says companies would need about 288,000 additional workers to compensate for lost hours. Dieese, a labor-linked research institute, calculates that cutting the workweek from 44 to 40 hours would raise wages’ share of manufacturing costs from 22% to 24%, which it says would not meaningfully affect macroeconomic indicators.
Jobs, Health and Politics
Supporters argue that a second weekly day off would reduce stress, burnout and health-related absences, especially in commerce, retail and services. A dossier cited by Folha from the University of Campinas says more than 90% of workers on the 6x1 schedule report physical or mental health damage.
Employment forecasts also diverge. Research by Insper professor Naercio Menezes Filho on Brazil’s earlier reduction from 48 to 44 weekly hours found no rise in unemployment and even a lower probability of job exit. Daniel Duque of FGV-Ibre and the Center for Public Leadership projects a loss of about 638,000 formal jobs, with heavier effects in construction, commerce and agriculture.
Employers have urged Senate President Davi Alcolumbre to slow the vote and hold a technical debate, preferably after the October elections. Ricardo Alban, head of CNI, said the issue should not be handled in haste.
Senators are already split. Oriovisto Guimarães of the Brazilian Social Democracy Party (PSDB), a center-right party, called the proposal electoral and warned of severe effects on schools and local governments that pay by the hour. Cleitinho, of Republicanos, defended faster approval, saying the issue is not ideological but about worker dignity. Izalci Lucas, of the Liberal Party (PL), said the key question is who will pay the bill, especially among small businesses.
