Brazil’s attention is on the aftermath of the election. Underneath that noise, a change to the Constitution that touches every employment contract in the country is already running on a clock.

From 16 December 2026, every employee in Brazil gets two paid rest days a week and a 42-hour cap. Twelve months later the cap drops to 40 hours. Salaries stay where they are, so the price of an hour of Brazilian labour rises by about 10% over 14 months, and any collective agreement built on 44 hours stops working on the day the first cap arrives.

If you employ people in Brazil through an EOR, or your clients do, this reaches you whichever way the political story ends.

WHAT WAS, AND WHAT WILL BE

Before, the legal maximum was 44 hours a week with one day off. Employers could spread that over six days, the 6x1 pattern, or over five days with longer shifts and Saturday compensated.

After, the maximum is 40 hours and two paid days off a week. The eight-hour day stays, so the reduction comes from fewer hours across the week, and the amendment bans any pay cut to match.

The impact falls on every 44-hour contract, which is the standard Brazilian employment contract. The Labour Ministry counts around 37 million people on them. For an employer the practical effect is the same in an office or a warehouse. The same salary now buys four fewer hours, the arrangements that made longer days legal lose their basis in December, and payroll, timekeeping and contract records have to catch up.

WHAT IT COSTS

Pay cannot go down. The amendment says so in plain terms, and it protects union-agreed minimums too. So the monthly salary stays where it is and the hours it buys shrink. Four fewer hours on the same money is roughly a 10% rise in the cost of each hour worked, and the government's own research institute puts the average across the economy at just under 8% once you account for people already on shorter weeks.

The hourly rate matters beyond the headline number, because overtime, night premiums and deductions for absence are all calculated from it. Every one of those gets more expensive at the same time. Anyone paid by the hour needs their rate raised, or their monthly pay falls, which is not allowed.

Sales teams on commission are a case of their own. Commission attracts a paid rest top-up calculated on the ratio of rest days to working days, and with a second rest day each week that top-up roughly doubles.

The quieter cost is coverage. A client that needs 44 hours of cover per role now needs a tenth more headcount, overtime at the higher rate, or a tighter rota. That is a conversation to have with clients before December, not after.

AGREEMENTS THAT STOP WORKING ON 16 DECEMBER

Article 3 of the amendment voids any collective agreement clause on hours or rest that conflicts with the new rules, two months after publication. A convention that fixes 44 hours over six days and runs until August 2027 loses that clause on 16 December 2026, without anyone denouncing it or going to court.

The common Saturday compensation arrangement, where staff work 48 extra minutes a day from Monday to Friday in exchange for Saturday off, loses its purpose. Saturday is now a rest day in a Monday to Friday schedule. Keep the 48 minutes and you are running 8h48 days against an 8-hour limit, which is overtime from day one.

Spreading 42 hours across five days means 8h24 a day, and that needs a collective agreement under Article 7. An individual agreement does not carry it. Without a union clause the safe route is eight hours a day, five days a week, which is 40 hours and gets you to the final cap a year early.

Hour banks survive. Annual banks still need a collective agreement and six-month banks still work on a written individual agreement, but the point at which an hour enters the bank moves on 16 December. Balances accrued under the old threshold need reviewing before then. 12x36 shift patterns average 42 hours and fit the transition, but at 40 hours in December 2027 their footing is unsettled and needs negotiating in advance.

WHAT THIS MEANS FOR EORS, STAFFING AGENCIES AND THEIR CLIENTS

If you employ people in Brazil, directly or through an EOR, you hold the contracts and the liability. The new limits apply to existing contracts on their own, with no addendum needed for them to take effect, but one is recommended anyway to avoid disputes later about which schedule applied on which day. More importantly, what has to move is everything around the contract. Payroll, timekeeping and eSocial records need to show the new hours. Overtime claims in Brazil reach back five years and can be filed up to two years after a contract ends, so a rota that is wrong in December 2026 is still a cost in 2031.

For staffing and outsourcing providers, the price of a placement changes twice in 14 months. Rate cards built on 44 hours a week need rebasing. Fixed-fee contracts signed before October are the ones to open first.

EORs serving overseas clients have a translation job. A client in London or New York paying a fixed monthly fee will see no change on the invoice, but their Brazilian team's capacity drops by four hours a week per person. Tell them now, with the dates, so the conversation is about planning rather than a surprise.

WHERE THIS LEAVES YOU

The rules themselves are not complicated. The hours drop, the pay does not, the Saturday arrangement goes, and the records have to catch up. What separates a tidy transition from an expensive one is timing, because every month a rate card or a rota stays on 44 hours is a month of overtime and paid rest building up in the background.

The first deadline is six weeks away and the second is already on the calendar. It’s time to take action.
