Opposition parliamentarians in the Brazilian Senate are evaluating an alternative constitutional amendment to block or modify the proposal to end the 6x1 work schedule.

This legislative maneuver represents a strategic effort to prevent the ruling coalition from claiming sole credit for labor reforms. By introducing a competing proposal, the opposition aims to protect workers' interests while maintaining political leverage over the final version of the law.

The 6x1 schedule currently allows for six consecutive work days followed by one day off [1]. The original proposal to end this system, known as PEC 221/2019, was previously approved by the Chamber of Deputies [2].

To counter this, Senator Davi Alcolumbre sent an alternative proposal, PEC 12/2026, to the Senate’s Comissão de Constituição e Justiça (CCJ) in late May [3]. This "plan B" focuses on a more flexible regime rather than a total ban on the 6x1 structure.

One key component of the opposition's alternative approach involves a reduction in the overall weekly work limit. The proposed amendment would reduce the standard workweek from 44 to 40 hours [4].

Lawmakers in the CCJ have spent recent sessions debating the merits of the different proposals. The opposition has criticized the original PEC during these votes, saying their alternative provides a more sustainable transition for businesses, and still benefits the workforce [5].

The clash between PEC 221/2019 and PEC 12/2026 highlights a broader political struggle in Brazil over labor rights and legislative branding. While both sides ostensibly support reducing worker fatigue, the opposition's push for a 40-hour week and flexible regimes suggests a preference for gradual systemic change over the more abrupt shift proposed by the ruling coalition.
