The enactment of Law No. 15,371/2026 introduces significant changes to the legal framework governing paternity leave in Brazil. The new statute gives definitive effect to the right provided for in the Federal Constitution and creates paternity pay as a social security benefit. It amends the Consolidation of Labor Laws, Law No. 8,213/1991 and Law No. 8,212/1991, bringing about a broader restructuring that affects both labor law and social security law.
One of the key changes is the gradual extension of paternity leave. The leave period is no longer limited to the five days provided for in the Transitional Constitutional Provisions Act and will now follow a progressive model of up to twenty days. The law also allows the leave period to be split, provided that the mandatory initial period is taken immediately after the birth, adoption or grant of judicial custody.
Another central feature of the statute is the creation of paternity pay, a social security benefit payable to the insured employee during the leave period. As a result, a significant portion of the cost associated with paternity leave will no longer be borne exclusively by the employer, but will instead be absorbed by the General Social Security System, in a manner similar to the existing maternity pay model.
The legislation also strengthens employee protection by providing for job protection during the leave period and for an additional period afterwards. This reinforces the legal protection afforded to family relationships and brings the paternity leave framework closer to the regime already consolidated for maternity leave.
Why does paternity pay reshape the funding logic of employment relationships?
The introduction of paternity pay changes how employee leave is treated from an economic standpoint. Although the extension of paternity leave, in principle, increases the period during which the employee is absent from work, shifting the financial burden to Social Security reduces the direct impact on businesses.
This transfer of costs reflects a change in the nature of the right itself. Paternity leave is no longer treated primarily as a matter of the employment contract and is instead framed as an element of social protection. At the same time, the measure increases pressure on the social security system, which will now assume a new obligation in an environment already marked by structural funding challenges.
The debate therefore extends beyond labor law and now also involves the sustainability of the social security system, requiring an integrated legal and economic analysis.
What are the impacts for businesses and employment relationships?
From a business perspective, the new legislation will require meaningful adjustments. The longer leave period, combined with the possibility of splitting the leave, calls for a review of internal policies, workforce planning and contractual arrangements.
The provision on job protection is also likely to affect workforce management, particularly in termination scenarios close to the period in which the benefit is granted. This may lead to an increase in disputes over the validity of employment terminations.
On the other hand, the redistribution of leave-related costs and the strengthening of fathers’ participation in family care may have positive effects in the workplace. These changes can contribute to a better balance in employment relationships and help companies align their practices with contemporary people-management standards.
How does Brazil compare internationally?
The extension of paternity leave and the creation of a specific social security benefit bring Brazil closer to models adopted in several countries that have developed more balanced parental leave systems. These systems generally combine leave periods for both parents with public funding mechanisms, with the aim of reducing gender inequality and encouraging greater participation by fathers in childcare.
Although the Brazilian model remains more limited than those of jurisdictions with longer and more flexible shared parental leave arrangements, the new legislation represents an important step toward a system that is more aligned with social change and the contemporary demands of the labor market.
What changes in the structure of Brazil’s labor and social security systems?
Law No. 15,371/2026 reflects a reshaping of Brazil’s legal framework by creating a deeper connection between labor law and social security law. By assigning a social security nature to the benefit, the statute reinforces the role of the State in protecting parenthood-related events and redistributes the burdens associated with time away from work.
This movement brings the Brazilian model closer to systems that treat family protection as a collective responsibility, rather than merely as a contractual obligation between employee and employer.
The new law therefore shows that paternity leave is no longer a residual right. It now occupies a strategic position in the organization of employment relationships and in the structure of the social security system. In this context, a proper understanding of the changes introduced by the statute will be essential to ensure legal certainty and efficient implementation for businesses, employees and the social security system itself.
