A constitutional amendment to end the six-day-on, one-day-off work schedule is moving to the Brazilian Senate after passing through the Chamber of Deputies [1].

The proposal, known as the "escala 6x1," aims to improve working conditions for millions of laborers. However, its progression now depends on Senate leaders who may delay the vote or alter the text to include broader labor flexibility measures [2, 3].

Minister Guilherme Boulos said on April 12, 2026, that while the vote in the Chamber was practically guaranteed, the Senate could "shelve" the project or change its content [1]. This transition marks a critical juncture for the government's labor reform agenda as it moves from the lower house to the more conservative upper house in Brasília [1, 3].

Senate President Davi Alcolumbre has signaled a cautious approach to the legislation. Alcolumbre said the Senate would not be merely a "rubber-stamping house" and that the text must pass through committees before a final vote [3].

Industry groups are actively lobbying against the measure. Paulo Skaf, president of the industry group FIESP, said the organization would reinforce its actions in the Senate by meeting with party leaders, and the Senate president, to discuss the amendment [1].

Reports from May 14, 2026, indicate that the amendment is currently a target for an offensive to include other labor changes [2]. These potential modifications could shift the focus from a simple reduction of work days to a more complex restructuring of employment contracts.

Senator Izalci Lucas (PL-DF) has also commented on the legislative trajectory, emphasizing the need for thorough examination within the Senate's committee structure to ensure the economic impact is fully understood [3].

The Senate could “shelve” the project or change its content.

The shift of the 6x1 PEC to the Senate transforms a popular labor movement into a complex political negotiation. By insisting on committee reviews, Senate leadership is creating a window for industry groups like FIESP to negotiate concessions, potentially trading the end of the 6x1 schedule for broader deregulation or flexibility in other labor laws.
