End of 6×1 Shift Advance Could Change Work Hours in Five Affected Sectors, with Impacts on Labor Market and Costs.
According to information published on September 1, 2026, by Poder360, the end of the 6×1 shift has progressed in Congress and could alter the operations of companies dependent on continuous processes. The PEC 221/2019 was approved by the Senate’s Constitution and Justice Committee (CCJ) on September 1, 2026, and is ready for Plenary analysis. The text proposes a gradual reduction of the work week to 40 hours, two paid rest days, and maintenance of salaries.
However, the Brazil Logistics Institute (IBL) warns of potential effects on costs, hiring, and the functioning of essential activities. In the entity’s assessment, five affected sectors deserve special attention: rail, road, port, aviation, and agribusiness.
Advancement of the 6×1 Shift Changes the Debate on Work Hours
The proposal under discussion establishes that the maximum weekly work hours be reduced from 44 to 40 hours without a reduction in pay. The text also stipulates two paid weekly rest days, with a preference for one to be on Sunday.

The change would not occur abruptly. According to the text approved by the CCJ, the workweek would initially be reduced to 42 hours and then reach the proposed 40-hour week. The 5×2 shift would become the general standard. The PEC still requires a vote by the Senate Plenary in two rounds, needing 49 favorable votes out of 81 senators for approval.
6×1 Shift Requires Adaptation in Continuous Activities
The IBL’s concern primarily lies in the necessity to maintain operations that cannot simply halt when a work hour reduction occurs.
According to the entity, logistics and infrastructure encompass essential services, continuous operations, and roles that depend on specialized workers. A rapid change could require new teams, shifts adjustments, and additional training.
The institute advocates for transitioning that considers the characteristics of each activity. The proposal includes collective bargaining, differentiated regimes, and mechanisms for adapting infrastructure contracts, concessions, and public-private partnerships.
The Five Sectors Affected by the Changes
The IBL provided specific estimates for the segments represented in its council. The numbers are not official government projections but are part of the assessment released by the entity regarding the potential effects of the change.
Among the main points raised are:
- increased need for workers in certain operations;
- greater pressure on overtime, training, and operational costs;
- difficulties in quickly replacing specialized professionals;
- the necessity to reorganize shifts and rest periods.
These factors can have different effects depending on the structure of each company. Therefore, the affected sectors should not be evaluated as if they had the same labor needs.
Rail Sector May Face Cost and Qualification Pressure
In the rail sector, the IBL estimates an impact of R$ 168 million per year. The organization also notes a possible increase in overtime and concerns about worker fatigue.
Another challenge lies in the availability of skilled professionals. Training these workers can take time, which complicates a prompt response when companies need to expand their teams.
Road Sector Faces Challenges in Trip Reorganization
In road transportation, the main difficulty highlighted is in organizing rest periods during long-distance trips. A shorter work shift may require more workers to maintain operational coverage. The IBL also cites a potential reduction in productivity, depending on how the new schedules are structured.
The impact could be significant since road transport is directly linked to supply, product distribution, and cargo movement across different regions of the country.
Ports and Aviation Depend on Specialized Teams
Port and airport activities have particularities that make personnel planning even more critical. In both cases, it is not enough to simply reduce hours: it is essential to ensure that there are workers available to maintain operations.
In the port sector, the IBL anticipates rising costs to maintain current production levels. The organization also mentions a minimum additional cost of 50% and operational deficits in a sector that already struggles to find qualified professionals.
Specialized training also presents a concern. When a role requires specific technical knowledge, replacing workers or rapidly expanding teams may not be straightforward.
Aviation May Face Impact on Routes and Teams
In aviation, the institute highlights operational safety, variable pay, and the availability of certified teams. The need for qualified professionals makes work schedule reorganization particularly sensitive. Depending on the operation, a company may need to review schedules, team compositions, and even the economic viability of certain routes.
This does not mean that the change will necessarily lead to cancellations or reduced flights. It is a risk highlighted by the IBL if adequate adaptation mechanisms are not in place.
Agribusiness Can Absorb Additional Costs
Among the figures presented by the IBL is an estimate of over R$ 800 million in additional costs just in the state of Mato Grosso. The calculation considers new hires and increased grain production costs.
Agribusiness operates in cycles of intensified activity and relies on a supply chain that includes production, storage, transportation, and distribution. Changes in worker availability may therefore require advance planning.
The estimate of R$800 million should be understood as a projection presented by the institute, rather than an official calculation of national economic impact.
Labor Market Will Play a Central Role in the Transition
The debate on the end of the 6×1 work schedule also involves the labor market. Proponents of reducing work hours argue that more rest can enhance quality of life and contribute to productivity. The PEC’s own record in the Senate notes potential consequences such as job creation, productivity gains, and the maintenance of wages.
On the flip side, labor-intensive sectors need to assess how to maintain their operations. If productivity per worker does not offset the reduction in hours, additional hiring may be necessary. The outcome will depend on factors such as the availability of professionals, training capacity, productivity, collective bargaining, and internal process adaptation.
End of the 6×1 Work Schedule May Also Change Contracts and Shifts
The IBL proposes a specific transition for essential activities. Suggested alternatives include schedules like 12×36, 4×4, and 3×3, along with a sectoral transition of 14 months in a single phase.
The entity also advocates for the rebalancing of infrastructure contracts, concessions, and PPPs. There is concern that contracts established under certain working conditions may incur cost increases after a constitutional change.
Thus, the institute’s proposal seeks to reconcile the reduction of working hours with the continuity of services. The aim is to prevent companies from having to make abrupt adjustments in operations that rely on long-term planning.
What Companies and Workers Should Monitor
As the PEC awaits deliberation by the Senate Plenary, companies and workers need to monitor the proceedings before considering any definitive changes to shifts.
Several points will be particularly important:
- definition of the effective schedule for reducing working hours;
- regulation of differentiated schedules;
- effects on collective agreements and conventions;
- rules for operations on Sundays and holidays;
- transitional measures for specific companies and sectors.
The PEC also allows for differentiated schedules applicable to specific activities, as per the rules outlined in the text and corresponding legislation.
A New Reality for the Labor Market
The end of the 6×1 schedule could represent one of the most significant changes in work hour organization in decades. The proposal combines a reduction in working hours, two days of paid rest, and the preservation of wages.
At the same time, the IBL’s warnings indicate that the transition will not be uniform across all companies. Railroads, road transport, ports, aviation, and agribusiness have distinct operational structures and depend, to varying degrees, on specialized professionals.
The challenge will be to find a model capable of increasing worker rest without compromising essential services or causing cost increases that ripple through the supply chain.
For the labor market, the discussion is merely entering a new phase. Approval by the CCJ signifies an important advancement, but the text still needs to pass through the Senate Plenary. Until then, companies, workers, and sectoral entities will need to closely monitor upcoming decisions and their potential effects on the Brazilian economy.
