Brazil’s Labor Reform Push: 40-Hour Work Week Advance Triggers Cost Alert for Service Sector
Brazil's Senate is set to vote on a constitutional amendment to reduce the work week from 44 to 40 hours without a pay cut, raising labor cost concerns.
A constitutional amendment that would reduce Brazil’s maximum work week from 44 to 40 hours without a corresponding salary cut is advancing quickly through the National Congress, triggering a significant cost alert for labor-intensive sectors in the country. The proposed amendment, which is strongly backed by the Workers’ Party (PT) and President Luiz Inácio Lula da Silva, has already passed the lower house and was recently approved by a key Senate committee, setting it up for a final vote in the full Senate. If approved, the measure will effectively end the common "6x1" work schedule—six days of work followed by one day of rest—and impose an immediate 10% increase in the hourly cost of labor for nearly one-third of Brazil's formally employed workers.
The proposal, known as PEC 221/2019, will introduce the change gradually to mitigate the impact on businesses. Within two months of its enactment, the maximum weekly workload would fall from 44 to 42 hours, with all employees guaranteed two paid rest days per week. The definitive reduction to 40 hours is mandated to take effect 14 months after enactment. Because the amendment strictly prohibits any reduction in nominal or proportional salary, it mandates that companies pay the same monthly wage for fewer hours worked, directly raising the cost of each man-hour.
Analysts and business groups have warned that the change will particularly pressure Brazil’s service, retail, and manufacturing sectors. For businesses with significant shift-work operations, such as pharmacies, restaurants, and apparel retailers in shopping malls, the elimination of the 6x1 schedule is expected to force immediate structural and financial adjustments. One study estimates that the reduction could increase the total costs for companies in some service sectors by nearly 7%. Another analysis suggests the measure could reduce the EBITDA of affected Brazilian retailers by between 10% and 15%.
This legislative push to hike the cost of labor is part of a broader shift in labor policy under the current administration. The PT's platform also includes a continued commitment to increase the national minimum wage above the inflation rate, a policy that has already resulted in significant real gains for workers. Concurrently, the administration has vowed to curb the practice of pejotização, a corporate cost-saving measure where workers are hired as legal entities (PJs) to avoid mandated benefits and labor taxes under the Consolidation of Labor Laws (CLT). The Supreme Federal Court (STF) has taken a key case with general repercussion to define the legal limits of this practice, which will have a binding effect on all companies across the country.
The constitutional amendment now moves to the Senate floor, where it requires the support of three-fifths of the senators to pass. With elections approaching, the proposal is highly popular, making it politically difficult for opposition lawmakers to reject outright, despite arguments that it will fuel inflation and hurt small businesses. Should the Senate pass the measure, it will mark the most significant change to Brazil's labor relations since the 2017 Labor Reform, forcing employers to model the financial impact and begin reviewing existing collective bargaining agreements and operational structures.
What it touches
The increased labor costs are expected to affect the valuations of companies in highly labor-intensive sectors, particularly Retail (including supermarkets and department stores), Food Service, and certain areas of Manufacturing where labor represents a large portion of operational expenses. Companies with existing thin profit margins and heavy reliance on the current 6x1 schedule face the most immediate need to adjust staffing and pricing models.
