Topic 1,046 of Brazil’s Supreme Federal Court (STF) confirmed that negotiated agreements take precedence over statutory law in labor matters. It also reignited the debate over the limits of Article 611-B of the CLT (Brazil’s Consolidated Labor Laws), especially in situations such as extended working hours in unhealthy environments.

The Scope of the Thesis Set by the Supreme Court

In judging Topic 1,046, the Supreme Federal Court held that collective agreements and collective bargaining conventions are constitutional when they, taking into account negotiated sectoral adequacy, limit or set aside certain labor rights, as long as absolutely unwaivable rights are respected. The decision reinforced the autonomy of collective will as a legitimate tool for regulating labor relations.

The thesis rested on the recognition that labor unions and employer unions have constitutional standing to shape waivable rights, weighing gains and losses for the benefit of the workers’ category. Article 7, item XXVI, of the Federal Constitution, which gives weight to the recognition of collective conventions and agreements, served as the central pillar of the argument.

The Supreme Court itself, however, drew the boundary: absolutely unwaivable rights remain beyond the reach of collective bargaining, even though Article 611-B of the CLT contains what appears to be an exhaustive list of non-negotiable subjects.

Article 611-B of the CLT and Its Illustrative Nature

The 2017 Labor Reform introduced Article 611-B, listing thirty items of rights that cannot be eliminated or reduced through collective bargaining. They include rules on professional identification, the minimum wage, the thirteenth-month salary, paid weekly rest, vacation, and constitutional additional pay.

The sole paragraph of that provision, however, states that rules on working hours and rest breaks are not considered occupational health, hygiene, and safety rules for purposes of item XVII. That wording has produced conflicting interpretations, especially on whether working hours may be extended in unhealthy environments through a simple collective agreement, without the prior license from the competent authority required by Article 60 of the CLT.

Most legal scholars and a significant share of the case law have held that the list in Article 611-B is illustrative, not exhaustive. Rights tied to a worker’s dignity, health, and physical integrity form an unwaivable core that goes beyond the literal text of the statute, as the Superior Labor Court (TST) has repeatedly recognized.

The Sensitive Issue of Extended Hours in Unhealthy Environments

The controversy comes into sharp focus when you look at the extension or offsetting of working hours in unhealthy activities. Article 60 of the CLT requires prior licensing from the authorities responsible for occupational medicine, a condition that has historically been treated as a public-order rule tied to protecting workers’ health.

After the Reform, and in light of the thesis in Topic 1,046, an argument emerged that this requirement could be set aside through collective bargaining. Recent decisions, however, have signaled that occupational health, hygiene, and safety rules remain unwaivable, even though the literal wording of the sole paragraph of Article 611-B may seem to suggest otherwise. By its nature, a worker’s health cannot be the subject of a collective deal without a prior technical assessment of the work environment.

Precedent Summary (Súmula) 85 of the TST, together with the settled understanding that hazard pay for unhealthy work and exposure to harmful agents are part of health protection, supports the view that unrestricted flexibilization would hollow out constitutional guarantees.

The Substantive Limits of Collective Autonomy

The debate over Topic 1,046 goes beyond the literal reading of isolated provisions. The question is how far collective autonomy can go without violating the essential core of fundamental labor rights, which make up a minimum civilizing standard.

Absolutely unwaivable rights include those whose elimination would affect a worker’s human dignity, health, safety, and life. These legal interests cannot be given up, even in exchange for economic compensation, because their protection stems directly from the constitutional order and from international treaties ratified by Brazil, notably the conventions of the International Labour Organization.

On the other hand, relatively unwaivable rights can be shaped through collective bargaining, provided the negotiation meets minimum standards of proportionality and real compensation, avoiding one-sided waivers disguised as agreements. Negotiated sectoral adequacy requires balance.

Frequently Asked Questions

What does Topic 1,046 of the Supreme Federal Court establish?

Topic 1,046 set a thesis of general repercussion recognizing the constitutionality of collective agreements and conventions that limit or set aside labor rights, as long as absolutely unwaivable rights are respected. The decision gives weight to the autonomy of collective will and to negotiated sectoral adequacy, balancing flexibility and protection.

Which rights cannot be made flexible through collective bargaining?

Absolutely unwaivable rights remain non-negotiable. These are rights tied to the minimum civilizing standard and to a worker’s human dignity, health, safety, and life. Article 611-B of the CLT lists non-negotiable subjects, but most legal scholars and case law understand that list as illustrative, not exhaustive.

Why is extending working hours in an unhealthy environment controversial?

Because Article 60 of the CLT requires prior licensing from the competent occupational medicine authority, a requirement traditionally tied to protecting workers’ health. The question is whether that requirement is part of the unwaivable core of health and safety rules, in which case collective bargaining could not set it aside, or whether it was swept up in the flexibilization brought by the Labor Reform.
