Spanish Dismissal Deadline: The 20-Working-Day Rule

Quick answer: a worker who wants to challenge a dismissal in Spain will generally have 20 working days from the effective date of dismissal. This is a limitation period, not a recommendation, and an incorrect calculation can cause the claim to expire.

What does the 20-working-day rule mean?

Article 103 of Spain’s Labour Jurisdiction Act states that a worker may challenge a dismissal within the 20 working days following the dismissal. The period is one of caducidad: once it expires, the dismissal claim may no longer be brought.

For this statutory calculation, Saturdays, Sundays and public holidays at the seat of the competent court are not counted. “Twenty working days” therefore does not mean 20 calendar days or simply four weeks.

When does the period begin?

The relevant date is normally the date on which the dismissal takes effect, which may differ from the date a letter was prepared, delivered or signed. The dismissal letter, payroll records, digital communications and the employee’s last working day may all be relevant.

If you are asked to sign a document, record the date you received it and retain a complete copy. Signing receipt of a letter is not necessarily the same as agreeing with its contents, but individual advice should be obtained before adding statements or waivers.

Does a conciliation request stop the clock?

Article 65 of the Labour Jurisdiction Act provides that filing the applicable prior conciliation or mediation request suspends the limitation period from the filing date. The calculation resumes under the statutory rules after the conciliation is attempted or after the relevant period passes without it taking place.

This is not a reason to delay. The number of days already used before filing remains important, and errors concerning the competent body, employer identity or claims included may create procedural problems.

Common mistakes made by international employees

• Counting calendar days rather than working days.
• Assuming negotiations with HR automatically suspend the limitation period.
• Waiting for a final payroll or severance payment before obtaining advice.
• Confusing notice of a future dismissal with its effective date.
• Assuming a PIP, settlement proposal or resignation document has no legal consequences.
• Relying on the rules of the employee’s home country instead of Spanish employment law.

What should you prepare for an initial review?

• The dismissal or termination letter and the date it was received.
• The employment contract and relevant amendments.
• Recent payslips and information about bonus, commission or equity.
• The effective termination date and last day worked.
• Relevant PIP, warning, HR or settlement communications.
• A short chronology of the important events.

Do not send extensive confidential material before the lawyer confirms the appropriate channel. A concise chronology and the key dates are usually the best starting point.

What happens during a case assessment?

1. Urgency and jurisdiction: the apparent deadline and connection with Spanish employment law are reviewed.
2. Documents and objectives: the dismissal grounds, contractual position and practical objectives are considered.
3. Available routes: the lawyer explains the relevant process, possible options and professional fees. No particular outcome can be guaranteed.
