Statute of Limitations in Spanish Labor Law: Deadlines for Expats

🇪🇸 Read the original in Spanish

In Spain's dynamic job market, time is just as crucial as the legal right you are claiming. Many employees and employers are unaware that claims arising from an employment contract cannot be made indefinitely. Instead, they are subject to strict time limits which, if exceeded, extinguish the possibility of obtaining effective judicial protection. Understanding the difference between losing a right simply due to the passage of time and the mechanisms to stop that clock is fundamental to safeguarding your financial and professional interests. In this detailed guide, we will analyze the limitation and expiration periods in Spanish labor law under the strict framework of the Estatuto de los Trabajadores (Workers' Statute) and current case law.

The Regulatory Framework: Prescription vs. Caducity in Labor Law

To safely navigate any labor claim in Spain, it is essential to distinguish between two legal concepts that, although similar in their practical effects (the loss of the right to claim), operate very differently: prescripción (prescription/statute of limitations) and caducidad (caducity/expiration).

The main regulatory framework is established in Real Decreto Legislativo 2/2015, de 23 de octubre, por el que se aprueba el texto refundido de la Ley del Estatuto de los Trabajadores (ET) (Workers' Statute), specifically in its Article 59, as well as in Ley 36/2011, de 10 de octubre, reguladora de la jurisdicción social (LRJS) (Law Regulating Social Jurisdiction). Secondarily, and to understand the rules of calculation, we refer to the Código Civil (Civil Code) (Articles 1969 and following).

• La Prescripción (Prescription): This is a legal mechanism by which the passage of time extinguishes the action to claim a right, but it allows for interruption. This means that if the worker makes a formal claim before the deadline expires, the clock is reset to zero and the entire period starts counting all over again.
• La Caducidad (Caducity/Expiration): This is a much more rigid and strict deadline. It does not allow for interruption, but only suspension in legally foreseen cases (such as filing a conciliation petition). When the period is suspended, the clock does not reset to zero; instead, it "freezes" and resumes from the exact day it stopped once the procedure is completed.

Key Prescription and Caducity Deadlines in Spanish Legislation

Spanish labor legislation establishes very short deadlines compared to civil law, aiming to provide legal certainty to production relations and prevent the indefinite accumulation of financial liabilities for companies.

1. The General Prescription Period of One Year (Salary Claims)

*Article 59.1 of the Estatuto de los Trabajadores establishes a general deadline of one year* for exercising actions derived from an employment contract that do not have a specially designated time limit.

This 1-year period is the star deadline applied to reclamaciones de cantidad (monetary claims for unpaid salaries, overtime, salary differences due to incorrect application of the collective bargaining agreement, night shift or rotating shift bonuses, and extraordinary payments).

• When does the countdown start? The 1-year period begins to run from the day the action could first be exercised. In the case of salaries, this is from the day they should have been received (usually at the end of the month or on the payment date established by agreement or custom).

2. The Caducity Period of 20 Business Days (Dismissals and Sanctions)

For the most critical actions in an employment relationship, the legislator has imposed an extremely brief deadline of 20 business days, regulated in *Article 59.3 of the Estatuto de los Trabajadores*** and in the LRJS. This deadline applies to:

• Despidos (Dismissals): Whether disciplinary, objective, or collective.
• Termination of temporary contracts: When the worker considers that the termination of the temporary contract is actually an unfair dismissal due to a contract concluded in fraud of law.
• Modificaciones sustanciales de las condiciones de trabajo (Substantial modifications of working conditions): Geographical relocation, changes to working hours, schedule, or work systems that the employee decides to challenge.

Crucial note on the calculation: The 20 days are business days (días hábiles), which means that Saturdays, Sundays, and public holidays (national, regional, and local holidays in the municipality where the court is located) are excluded from the count. The month of August is non-business (inhábil) for dismissal actions in the judicial phase, although this comes with specific details that demand extreme caution.

3. Specific Social Security Deadlines

In the area of Social Security benefits, regulated by Real Decreto Legislativo 8/2015, de 30 de octubre, por el que se aprueba el texto refundido de la Ley General de la Seguridad Social (LGSS) (General Social Security Act), the deadlines vary significantly:

• Prescription of benefits: The right to the recognition of benefits prescribes after 5 years, counted from the day following the day on which the event giving rise to the benefit occurs (Article 53 of the LGSS), except for retirement, death, and survivor benefits which, as a general rule, are imprescriptible (never expire).
• Caducity of single-payment benefits: The right to receive lump-sum, one-off benefits expires after one year, counting from the day following the notification of its approval to the interested party.

Practical Examples with Real Figures

To understand how these deadlines operate in daily life, we will analyze two common scenarios in the Spanish labor market.

Example 1: Claiming Unpaid Salaries (Prescription)

Let's imagine Carlos, a web developer working in Madrid. His company fails to pay his salary for October 2023, which amounted to €2,100 net, and which should have been paid on October 31, 2023.

• Start of the countdown: The 1-year period to claim this €2,100 starts on November 1, 2023.
• Initial deadline: Carlos has until October 31, 2024, to file a lawsuit or interrupt the prescription.
• Carlos's action: On June 15, 2024, Carlos sends a formal burofax (certified registered mail) to the company demanding payment of his salary.
• Legal effect: Since this is a prescription period, the burofax interrupts the deadline. The 1-year clock resets completely. Now, Carlos has until June 15, 2025, to file a lawsuit if the company still refuses to pay.

Example 2: Challenging a Disciplinary Dismissal (Caducity)

Now let's look at Elena, who is dismissed on disciplinary grounds on Friday, March 1, 2024.

• Start of the countdown: The 20 business days start counting on Monday, March 4, 2024 (the weekend does not count).
• Day-by-day calculation:
• Week 1 (March 4 to 8): 5 days elapsed. 15 remaining.
• Week 2 (March 11 to 15): 5 days elapsed. 10 remaining.
• Week 3 (March 18 to 22): Let's assume March 19 is a public holiday in her autonomous community. That week counts as 4 business days. 6 remaining.
• Week 4 (March 25 to 29): It is Easter (Semana Santa). March 28 (Maundy Thursday) and March 29 (Good Friday) are public holidays. That week counts as only 3 business days. 3 remaining.
• Week 5 (April 1 to 3): The final 3 days are used.
• Deadline: The caducity period to file the conciliation petition or the lawsuit expires on April 3, 2024. If Elena files her claim on April 4, 2024, her action will have expired (caducado), the dismissal will be completely unchallengeable, and she will lose any right to severance pay.

Step-by-Step Practical Steps to Claim and Stop the Clock

If you face a breach of contract by your employer or a dismissal, you cannot go straight to the Juzgado de lo Social (Labor Court) in most cases. You must follow a mandatory, prior administrative procedure.

Step 1: Drafting and Filing the Papeleta de Conciliación

Before taking judicial action, you are required to attempt an out-of-court agreement through the Servicio de Mediación, Arbitraje y Conciliación (SMAC — Mediation, Arbitration, and Conciliation Service, or the equivalent body in your Autonomous Community).

• You must draft a Papeleta de Conciliación (conciliation petition) detailing the facts, the amounts claimed, or the reasons why you are challenging the dismissal.
• Effect on deadlines: Filing this petition suspends the 20-day caducity period (in case of dismissal) and interrupts the prescription period (in case of monetary claims).

Step 2: The Suspension Period and the Conciliation Hearing

Once the petition is filed, the caducity period for the dismissal stops for a maximum of 15 business days (Article 65.1 of the LRJS).

• If the conciliation hearing has not taken place within those 15 business days, the 20-day clock starts running again from day 16.
• If the hearing takes place within that window, the period resumes the day after the hearing (regardless of whether it ends con avenencia [with agreement] or sin avenencia [without agreement]).

Step 3: Filing the Lawsuit before the Labor Court

If the conciliation hearing ends sin avenencia (without agreement) or the company fails to appear, you must draft and file a formal lawsuit before the Juzgados de lo Social (Labor Courts).

• You must attach the official SMAC certificate to the lawsuit to prove that you have attempted the mandatory prior conciliation.
• You must strictly respect the remaining days of the caducity period that resumed after the conciliation hearing.

Mistakes You Must Avoid

Making a mistake with deadlines in Spanish labor law is usually irreversible due to the rigidity of the labor courts. Avoid these errors at all costs:

• Confusing business days with calendar days: Counting Saturdays, Sundays, or holidays within the 20 days for dismissal can cause you to file a lawsuit much earlier than necessary out of fear, or worse, calculate incorrectly by forgetting to subtract local holidays, believing you have more time than you actually do.
• Relying on verbal negotiations: Verbal promises from the company ("we are looking into your case," "we will pay you next month") do not stop the prescription or caducity clock. Only a formal written claim (a burofax with acknowledgment of receipt and certified text) or the papeleta de conciliación has the legal power to interrupt or suspend deadlines.
• Forgetting the SMAC suspension limit: Believing that the dismissal deadline remains frozen indefinitely from the moment you file the conciliation petition until the hearing takes place is a critical mistake. Remember, the suspension limit is 15 business days; from day 16, the 20-day countdown resumes even if the SMAC has not yet scheduled your appointment.
• Letting the year pass to claim severance settlements: The finiquito (severance settlement) is a liquidation of salary concepts and proportional parts of extra payments. Although linked to the termination of the contract, the deadline to claim the amounts reflected in it (or omitted from it) is 1 year, not 20 days. However, you should not delay, to prevent concepts from the beginning of the year from prescribing.

Frequently Asked Questions (FAQ)

What happens if the last day of the caducity period falls on a Saturday or holiday?

If the expiration date of a procedural deadline (such as the 20 days for dismissal) falls on a non-business day (Saturday, Sunday, or holiday), the deadline is automatically extended to the very next business day. However, for legal safety, it is always recommended not to wait until the last minute to avoid technical issues on filing platforms like LexNET.

Can I claim unpaid salaries from three years ago if I am still working at the company?

No. The prescription period to claim salaries is 1 year from the time they should have been received. Therefore, any monthly payments older than 12 months will have prescribed, and the company will have no legal obligation to pay them, even if they admit the debt existed at the time, provided you have not made intermediate claims that interrupted the deadline.

If I am on medical leave (Incapacidad Temporal), does the deadline to challenge my dismissal stop?

No. A worker's temporary disability status does not suspend or interrupt the 20 business days caducity period to challenge a dismissal. The worker must file the conciliation petition and the lawsuit within the legal timeframe, and can be represented by a legal representative or a lawyer via a power of attorney.

What is the deadline to claim damages for a workplace accident?

The deadline to claim compensation for damages resulting from a workplace accident or occupational illness is 1 year (prescription). The calculation of this year begins from the moment the worker is fully recovered or when the permanent sequelae are officially determined by the corresponding resolution of the Instituto Nacional de la Seguridad Social (INSS — National Social Security Institute).

Summary

• Monetary claims (salaries, overtime, bonuses) prescribe after 1 year from the moment they could be claimed.
• Challenging dismissals, sanctions, or modifications of working conditions has a strict caducity period of just 20 business days.
• Prescription can be interrupted indefinitely through an out-of-court claim (such as a burofax), resetting the clock to zero.
• Caducity cannot be interrupted; it can only be suspended temporarily (for a maximum of 15 business days) by filing a conciliation petition with the SMAC.
• Ignorance of these deadlines or relying on informal negotiations with your employer usually leads to the irreversible loss of your financial and labor rights in Spain.
