The 6×1 schedule is not a detail. It is the foundation of food retail
For decades, the Brazilian supermarket sector has been built on a silent pillar: the 6×1 schedule. Working six days and taking one day off is not a cultural preference. It is an operational response to a business that runs seven days a week, with peaks concentrated on weekends and extremely tight margins.
Constitutional Amendment Bill 148 of 2015, particularly following the amendments approved by the Committee on the Constitution and Justice in 2025, directly addresses this very pillar. For the first time, the 6×1 rotation system is no longer merely a practice open to question; it is now structurally precluded by the text of the Constitution.
What will actually change as a result of PEC 148
The latest version of the PEC introduces three points that, combined, make the 6×1 schedule impracticable in food retail:
A limit of up to five working days per week
Requirement for at least two days’ paid weekly rest
Full pay retained, even with reduced working hours
In practice, this does away with the six-day working week for employees. Not as a result of negotiation, but by constitutional design.
The planned transition keeps the 44-hour week until the end of the year of enactment, reduces it to 40 hours the following year, and continues down to 36 hours per week. But the most significant impact is not just the reduction in hours. It is the disruption of the scheduling model.
Why is the supermarket sector feeling the pinch more than other sectors?
The supermarket sector operates under very specific conditions:
Stores open 12 to 18 hours a day
Open seven days a week
High labor density per square meter
Reliance on rotating shifts to cover peak periods
Net margins between 1.5 and 3 percent
In an environment like this, the 6×1 schedule is not a luxury. It is what balances cost, coverage, and service level.
By eliminating this schedule, the supermarket needs to redesign its entire operating logic.
The direct impact of eliminating the 6×1 schedule
Complete re-engineering of work schedules
With just five working days per employee, there are more shifts, more swaps, greater management complexity, and less flexibility to cover absences and demand peaks.
Inevitable increase in headcount
The reduction from 44 to 36 hours represents about 18 percent fewer available hours per person. To maintain the same level of service, it will be necessary to hire between 15 and 25 percent more employees, depending on the store format.
Structural increase in costs
Salaries cannot be cut. Payroll charges rise proportionally. In a sector with minimal margins, this puts direct pressure on EBITDA and turns operational efficiency into a matter of survival.
The weekend becomes a critical bottleneck
With two days of weekly rest, preferably on Saturday and Sunday, supermarkets face understaffing precisely on their highest-revenue days.
The result is predictable:
Higher cost of premium labor
Operational stress at peak times
Drop in service level
A genuine debate on Sunday closing
Closing on Sundays is no longer taboo
Since March 2026, supermarkets in Espírito Santo have been closing on Sundays under the terms of a collective agreement. The trial will run until October, with a review scheduled.
This shows something important: Sunday closing is no longer ideological and has become an operational engineering tool for dealing with the shock of costs and working hours.
The hidden risk created by the end of the 6×1 schedule
Closing stores on Sundays or operating with minimal staff has a side effect that is rarely discussed: long periods without human inspection.
A typical shutdown results in around 34 hours without operational presence, from Saturday evening until Monday morning.
During this interval, failures in refrigeration, cold rooms, or refrigerated display cases can progress silently. When the store reopens, the situation may include massive product loss, financial loss, health risk, and reputational damage.
With fewer staff in the store, operational risk grows non-linearly.
Automation is no longer just a strategy. It has become infrastructure
The elimination of the 6×1 schedule accelerates an inevitable transformation.
Supermarkets are now relying more on:
Building automation
Continuous monitoring of refrigeration, power and HVAC
Smart alarms and automatic prioritization
Remote operations and 24/7 operations centers
Interestingly, a constitutional amendment designed to protect jobs may actually accelerate the replacement of low-skilled work with automated systems. Not for ideological reasons, but for reasons of operational mathematics.
Large chains are able to invest. Regional chains are seeing their margins squeezed. Independent stores face a real risk of becoming unviable.
There is a possible offset in energy costs
When implemented effectively, Sunday closures can significantly reduce energy consumption.
Based on NEO operational data, closed and properly managed stores consume 40 to 60 percent less energy during this period, which represents a reduction of about 7 percent in total monthly consumption.
But this gain only happens with automation and continuous monitoring. Without technology, the risk outweighs the benefit.
What will change for supermarkets from now on?
Whatever the final outcome of the PEC, one thing is already clear. The 6×1 schedule is no longer a safe assumption.
Supermarkets will have to choose between:
Raise prices
Reduce service level
Reduce opening hours
Automate aggressively
Or combine all these levers
Final summary
The debate over the 6×1 schedule is not a labor issue. It is a structural one.
By making this model unviable, PEC 148 forces a deep reorganization of food retail. Fewer people in the store, fewer available hours, and greater operational risk call for a clear response.
For supermarkets, efficiency is no longer a competitive advantage but a prerequisite for survival. For those operating critical infrastructure, monitoring and automation are no longer merely supplementary tools but form the very foundation of the business.
In short, the end of the 6×1 schedule does more than just reduce working hours. It redefines how the supermarket operates.
With the end of the 6×1 schedule, operating with fewer staff has become the rule.
