Non-Payment of the Seniority Bonus

Legal Nature of the Seniority Bonus

The seniority bonus is recognized as a non-waivable right directly linked to the employee’s length of service. Its mandatory nature means that it cannot be disregarded through agreements between the parties or omitted by the employer.

This right is grounded in constitutional principles such as labor protection and the primacy of reality, as recognized by the Political Constitution of the State. In addition, implementing regulations establish that it is calculated on the basis of the national minimum wage, applying a progressive percentage scale.

When this benefit is not paid during the employment relationship, the obligation remains in force and must still be fulfilled even at the time of termination.

Judicial Principles Applicable to Non-Compliance with the Seniority Bonus

Protective Principle and Substantive Justice

Labor judges prioritize substantive justice over excessive formalism. This means that even where there are formal deficiencies in the claim, the aim is to protect the employee’s substantive right.

Reversal of the Burden of Proof

One of the most important mechanisms is the reversal of the burden of proof. In these proceedings, it is not the employee who must prove that the bonus was not paid; rather, it is the employer who must prove compliance through valid documentation.

This rule responds to the structural inequality between the parties, considering that the employer holds payroll records and payment documentation.

Non-Waivability and Non-Extinguishment to the Employee’s Detriment

The bonus cannot be waived or extinguished by the passage of time to the detriment of the employee. Even if it was not claimed in a timely manner, it remains judicially enforceable.

How to Judicially Claim Payment of the Seniority Bonus

Labor Claim for Employment Benefits

The employee may file a labor claim seeking payment of the seniority bonus as part of employment benefits. In this proceeding, the judge will assess the employment relationship and the length of service.

If the employer fails to prove payment, the court will order the corresponding reimbursement.

Flexible Evaluation of Evidence

Judges apply the principle of free evaluation of evidence, which means they may consider various elements such as:

• Payroll records
• Employment contracts
• Internal records
• Witness testimony

Even non-traditional documents may be admitted if they help establish conviction regarding the existence of the employment relationship and the time worked.

Certificate of Years of Service (CAS)

Although there is legislation referring to this certificate, case law has established that it is not always mandatory.

It is not required when the employee has provided continuous service within the same entity and there are other means of proving seniority.

It is necessary when the employee seeks to accumulate years worked across different institutions.

Requiring this document in every case may amount to a violation of the protective principle in labor matters.

What Happens If the Employer Does Not Pay the Seniority Bonus?

When the employer fails to pay the seniority bonus, the following legal consequences arise:

• Obligation to pay the outstanding amount
• Possible adjustment or reimbursement of the benefit
• Judicial recognition of the right through a court ruling
• Evidentiary burden against the employer

Where the employer claims to have paid the benefit, that assertion must be supported by reliable documentation; otherwise, the judge may presume non-compliance.

Relevant Case Law Interpretation

The case law of the Supreme Court of Justice has reinforced fundamental criteria:

• The bonus is a vested and enforceable right
• Non-payment creates a subsequent obligation
• Excessive formal requirements cannot be imposed when the time worked is sufficiently established
• The employer cannot benefit from its own omission

These criteria strengthen employee protection and ensure the effectiveness of the judicial claim.

In summary, non-payment of the seniority bonus activates a series of judicial mechanisms aimed at protecting the employee, especially the reversal of the burden of proof, the relaxation of excessive formal requirements, and the comprehensive evaluation of evidence. Both legislation and case law favor the actual employment reality over formalism, ensuring that this right is effectively recognized and paid.
