Brazil's lower house has approved a landmark constitutional amendment establishing a 40-hour, five-day workweek, marking a historic shift in labor protections for millions of workers who currently face six-day schedules with minimal additional compensation.
The amendment, sponsored by President Luiz Inácio Lula da Silva and approved Wednesday, will eliminate the sixth workday without reducing pay for at least 37 million people. It guarantees two consecutive 24-hour rest days each week, preferably Saturdays and Sundays. Currently, Brazilians work five eight-hour days and four hours on a sixth day for 44 hours total.
Who Bears the Burden
The change directly addresses inequality in Brazil's labor market. Paulo Pimenta, Brazil's government whip in the lower house, framed the amendment as an issue of basic fairness: "People who have this workweek from Monday to Saturday are the ones that have to work the hardest and are paid the least. We need to be brave and do justice."
The amendment is widely popular ahead of presidential elections in October, reflecting public support for stronger worker protections. Many opposition lawmakers voted for it after months of pressure from their constituents, demonstrating the grassroots demand for labor reform.
Business Concerns and Compromise
The amendment gives businesses 14 months to adapt to the new requirements—a key concession negotiated during the legislative process. Many business leaders and lawmakers had initially wanted the changes to be made gradually over 10 years, but the amendment's drafters resisted a prolonged transition.
Leo Prates, who drafted the amendment in the lower house, defended the approach: "This was built with a lot of responsibility, thinking about workers and families in Brazil. We need to accomplish this for the Brazilian people."
Some lawmakers continued to express concerns about implementation. Kim Kataguiri cautioned that "workers should know they might end up worse than they are now if business leaders stop hiring," though such arguments were outweighed by the vote.
Regional Momentum for Worker Protections
Brazil's move joins a broader regional trend toward stronger labor standards. In February, Mexican lawmakers approved a proposal by President Claudia Sheinbaum to trim the 48-hour workweek, with working hours to be shortened gradually to 40 hours by 2030. Chile passed the so-called 40-Hour Law in 2023, which reduced its workweek to 40 hours without reducing pay, applying to all workers under Chile's Labor Code.
However, the regional picture is mixed. Argentina has moved in the opposite direction under libertarian President Javier Milei. A labor overhaul package passed earlier this year extends the maximum workday from eight to 12 hours and scraps overtime pay, among other measures that Argentine labor unions say favor companies over employees.
Next Steps
The lower house vote Wednesday sent the amendment to Brazil's Senate, which has not set a date for its vote and could make changes before Lula's approval for the constitution to be amended. Brazil's main opposition figure, Sen. Flávio Bolsonaro, has proposed an alternative approach: replacing the current workweek system with a more flexible payment-by-the-hour strategy, which so far appears popular only among some business leaders.
Why This Matters:
The amendment addresses a structural inequality in Brazil's labor market where millions of workers—disproportionately lower-wage employees—have borne the cost of extended work schedules without proportional compensation. By establishing a constitutional floor for rest time and eliminating the six-day workweek without pay reduction, the measure treats worker wellbeing as a collective responsibility requiring institutional protection rather than individual negotiation. The 14-month implementation period reflects a deliberate choice to balance worker rights with business adjustment capacity, rejecting both indefinite delays and immediate disruption. The amendment's passage demonstrates how labor standards can be reformed through democratic processes when public pressure aligns with political will, offering a counterpoint to Argentina's recent labor deregulation and highlighting ongoing regional contestation over whose interests—workers' or employers'—should be prioritized in labor policy.
