Brazil's congress has approved a constitutional amendment to cut the maximum work week to 40 hours, a landmark labor reform that could affect 30 million workers and deliver a political win for leftist president Luiz Inácio Lula da Silva. The measure, which also bans six-day workweeks, passed the Senate on Wednesday and now heads to promulgation.
What the New Work Week Means for Brazilian Workers
The amendment reduces the standard work week from 44 to 40 hours, granting many employees an extra day off each week. It specifically prohibits the 6x1 schedule (six days on, one day off), which currently affects 16 million people. The change is expected to benefit low-wage workers in retail, restaurants, and hotels—sectors where Lula lost significant support since the 2022 election.
Key provisions of the amendment:
- Maximum work week reduced from 44 to 40 hours
- Six-day workweeks banned for all workers
- Affects over 30 million workers, primarily in service industries
- Implementation timeline to be determined by subsequent legislation
Political Context: Lula's Victory Ahead of Runoff
The approval comes less than two weeks before Brazil's presidential runoff, where Lula faces far-right senator Flávio Bolsonaro. Lula has championed the amendment as a win for workers, while Bolsonaro initially opposed it but reversed his stance on Tuesday, saying "the majority of Brazilian workers" supported it. On Wednesday, he joined 75 senators in approving the reform; only one senator, Hamilton Mourão, voted against it.
Lula celebrated on social media, writing: "Ending the 6x1 schedule is about more than changing working hours. It's about restoring dignity to those who build this country." The timing suggests the amendment could boost Lula's support among working-class voters ahead of the runoff.

Economic Impact: What It Means for Businesses
The reduction in working hours could increase labor costs for employers, particularly in labor-intensive sectors like retail and hospitality. However, proponents argue that shorter work weeks can boost productivity and improve worker well-being. Similar reforms in other countries have shown mixed results, with some businesses reporting higher efficiency and lower turnover.
| Country | Standard Work Week | Impact on Productivity |
|---|---|---|
| Brazil (new) | 40 hours | Expected to improve work-life balance |
| France | 35 hours | Stable productivity, higher labor costs |
| Germany | 40 hours | High productivity, strong worker protections |
| Japan | 40 hours | Overwork culture persists despite law |
Business groups have expressed concerns about the speed of implementation and potential cost increases. The government is expected to introduce transition measures to help small businesses adapt.
FAQ
When will the 40-hour work week take effect in Brazil?
The amendment has been approved by Congress but requires promulgation and subsequent regulation to determine the exact implementation timeline. Experts expect a phased rollout over the next 12 to 24 months.
Which workers will be affected by the change?
The reform primarily impacts workers in retail, restaurants, and hotels, as well as others currently working six-day weeks. Over 30 million workers are expected to benefit from the reduced hours.
Will workers receive the same pay for fewer hours?
Yes, the constitutional amendment does not allow for proportional salary reductions. Workers will maintain their current pay while working fewer hours, which could increase labor costs for employers.
The reform marks a significant shift in Brazil's labor landscape and could set a precedent for other emerging economies. As the country prepares for the runoff, the political ramifications are likely to resonate beyond the workplace.
