End of the 6x1 Work Schedule: What Constitutional Amendment No. 141/2026 Changes for Businesses

The 6x1 work schedule, a model in which the employee works six days for just one day of rest, has long been a subject of debate among business owners, unions and lawmakers. Enacted and published on October 16, 2026, Constitutional Amendment No. 141 permanently changes this scenario, imposing a structural transition in the weekly work schedule and paid rest for Brazilian workers. For business owners, HR managers and accountants, the change is not merely symbolic: it directly affects shift schedules, payroll, collective bargaining agreements and existing contracts.

Understanding the deadlines, the legal requirements and the practical effects on wages and the paid weekly rest period, known as DSR, is essential so that the adjustment happens without labor liabilities and without surprises on the payroll.

What changes in the work schedule and weekly rest

The amendment establishes a staggered reduction of the maximum weekly work schedule. Starting December 16, 2026, the maximum schedule becomes 42 hours per week, with the right to two days of paid weekly rest, one of which should preferably fall on Sunday. In a second phase, starting December 16, 2027, the maximum schedule drops again, to up to 40 hours per week. In practice, this means the logic behind the 6x1 schedule loses ground to models that guarantee two days off, bringing Brazil closer to broader rest standards than those previously practiced in several sectors, such as retail, services and customer-facing work.

One point that deserves extra attention from managers is the express prohibition on reducing wages or the salary floor because of this change, set out in Article 2 of the amendment. In other words, the reduction in working hours can never be used as justification for cutting an employee's pay. The cost of adjusting the work schedule therefore falls on the company, not on the worker.

Deadlines every manager needs on the calendar

To organize internal planning, it helps to have a clear picture of the dates that take effect. On October 16, 2026, the amendment is enacted and published, marking the starting point for counting the other deadlines. On December 16, 2026, the maximum 42 hour work week and the two days of paid rest take effect, with a preference for one of them falling on Sunday, along with the loss of effect of any collective bargaining clauses that are incompatible with the new rule, under Article 3. On October 16, 2027, the one year deadline expires for contracts signed with government entities to be amended and brought into line with the new schedule. On December 16, 2027, the second phase of the reduction takes effect, with the maximum schedule dropping to 40 hours per week. This staggered timeline gives companies a window to reorganize shift schedules, but it requires advance planning, since the first change already affects operations this year.

Impact on hourly wages and the DSR calculation

One of the most sensitive effects on payroll involves the divisor used to calculate the hourly wage. With the 44 hour work week currently practiced by many companies, the usual divisor is 220. With the schedule dropping to 42 hours starting in December 2026, the divisor becomes 210, and in the second phase, with the 40 hour schedule, the divisor adjusts to 200. Since the salary stays the same, dividing it by a smaller number results in a higher hourly rate, which automatically raises the cost of overtime and other amounts calculated based on that divisor.

In addition, the increase in the number of paid weekly rest days within the month proportionally raises the amount of DSR owed on regular overtime and commissions. This happens because the DSR is calculated based on the average of these variable amounts, divided by the number of business days and multiplied by the number of rest days in the period. With more rest days in the month, the result of this calculation tends to be higher. For salaried employees, the DSR is already built into the fixed salary amount, but the impact still shows up in the calculation of overtime and commissions paid on top of the monthly salary.

Collective bargaining agreements and alternative compensation arrangements

The amendment makes clear that collective bargaining clauses that are incompatible with the new rule lose their effect starting December 16, 2026. This means that companies that currently rely on collective agreements to maintain different shift schedules will need to review those instruments with the relevant unions before that date, or risk having the general rule applied automatically. Forms of compensation other than the 5x2 model, meaning five days of work for two days off, can only be adopted through an agreement or collective bargaining convention, always respecting the average of two rest periods per month and guaranteeing at least one rest day in each week actually worked. This allows some flexibility for sectors with specific operational needs, but it requires formal, documented negotiation.

Government contracts, MEI, ME and EPP businesses

Companies that hold contracts with government entities have until October 16, 2027, that is, one year from the enactment of the amendment, to amend those contracts and bring them into line with the new work schedule, which may involve revising prices and contractual terms given the increased labor cost. As for individual microentrepreneurs (MEI), microenterprises (ME) and small businesses (EPP), the amendment provides that transition rules will only exist if a specific supplementary law addresses the matter. Until that supplementary law is enacted, there is no automatic differentiated regime for these business sizes, which reinforces the need to keep track of future regulations.

How companies should prepare

Given this scenario, the practical recommendation is to begin the internal review as soon as possible. Companies need to reorganize work schedules to accommodate the two days of weekly rest already starting in December 2026, review current collective agreements and conventions to identify clauses that may lose effect, adjust payroll and timekeeping systems to reflect the new divisor and the new DSR calculation, and map out government contracts that will require amendment within the one year deadline. Companies enrolled in Simples Nacional or classified as ME or EPP should closely monitor the enactment of any supplementary law on transition rules for these business sizes.

Since this change involves constitutional rules, collective bargaining agreements and direct impacts on payroll, each company should ideally assess its specific situation with specialized legal support before altering employment contracts, shift schedules or internal compensation policies, avoiding both noncompliance with the new rule and mistaken interpretations that could create unnecessary labor liabilities.
