Supreme Court Justice Flávio Dino said Tuesday that he expects to issue a decision by Friday on unresolved questions surrounding Brazil’s transition to a five-day workweek. The dispute centers on how to implement Constitutional Amendment 141/2026, which eliminates the six-day work schedule and gradually reduces the maximum workweek to 40 hours.

Dino, who is overseeing two constitutional challenges, ADIs 8041 and 8042, made the announcement at the end of a conciliation hearing at Brazil’s Supreme Federal Court. The proceedings brought together representatives of employers and labor unions to discuss the timeline and practical consequences of the new rules.
