Lula-Backed 40-Hour Work Week Proposal Reaches Critical Senate Committee

The Brazilian Senate’s most influential committee has received a proposal to reduce the maximum work week from 44 to 40 hours, a move backed by the Lula administration that would represent the country’s most significant labor law change in years. Senate President Davi Alcolumbre sent the Constitutional Amendment Proposal (PEC 221/19) to the Constitution and Justice Committee (CCJ) this week, setting the stage for a contentious debate over labor costs and worker rights ahead of the next major election. The proposal, which already passed the lower Chamber of Deputies, guarantees two days of paid weekly rest, effectively ending the common “6x1 scale” where a worker gets only one weekly day off.

The referral follows direct negotiations between Alcolumbre and President Luiz Inácio Lula da Silva, marking the proposal as a political priority for the government. The move signals a thaw in relations between the two leaders, which had been strained earlier this year. For the Lula administration, the measure is seen as a way to boost consumer purchasing power by ensuring no salary reduction for a four-hour reduction in work time—an effective increase in hourly wages—and fulfilling a key promise to the worker base that supported his return to office.

The CCJ, which is considered the Senate’s most important gatekeeper, must first decide on the proposal’s constitutionality before it can advance to the full Senate floor. The committee's scrutiny is critical; if the CCJ rejects the PEC, the proposal is generally considered dead. If approved, the reduction would be phased in: workers would first see a reduction to 42 hours and a guaranteed second day of rest within two months of the law’s promulgation, with the full 40-hour work week implemented about a year later. The text preserves the possibility of collective agreements for special regimes like the 12x36 shift and essential activities such as healthcare and security, provided the two paid weekly rest days are maintained.

The proposed labor reform will face intense opposition from the business sector, which argues that a mandatory wage-neutral reduction will lead to a significant increase in labor costs and a decrease in productivity, especially for small and medium-sized enterprises. The debate within the Brazilian Senate will now center on the CCJ, where a rapporteur, Senator Omar Aziz (PSD-AM), has been assigned to draft an opinion. His report will kick off a high-stakes legislative battle that requires a three-fifths majority in the full Senate, across two separate votes, to successfully amend the constitution.

What it touches The mandatory reduction in the work week without a corresponding reduction in pay represents a direct and quantifiable increase in hourly labor costs for companies across all sectors of the Brazilian economy, particularly those operating with low margins or large hourly workforces. Conversely, the expected rise in the real income of millions of workers could provide a boost to consumer-facing sectors, potentially affecting retail and consumer goods stocks traded on the B3 stock exchange.
