Company collective agreements in Spain represent one of the most relevant tools for organisations seeking to adapt certain employment conditions to their own business reality.
Unlike sectoral collective agreements, which establish a common framework for all companies operating within a particular activity, a company collective agreement allows an organisation to develop specific rules taking into account its organisational, production-related and economic characteristics.
For many organisations, particularly those with complex structures, international operations or specific working models, having their own collective framework can provide greater consistency and stability in their employment relationships. However, negotiating a company collective agreement should not be understood solely as an opportunity for adaptation. It also involves significant legal requirements relating to the standing of the negotiating parties, compliance with legal limitations and the need to conduct a genuine and transparent negotiation process.
A properly designed collective agreement can become a business organisation tool. Conversely, poorly structured negotiations can generate collective disputes, judicial challenges and problems with future implementation.
What Is a Company Collective Agreement in Spain?
A company collective agreement in Spain is a statutory agreement negotiated between the company and the duly authorised representatives of its employees that regulates employment and working conditions within the organisation.
Its regulation is primarily contained in Title III of the Employees’ Statute, which establishes both the rules applicable to collective bargaining and the requirements for a collective agreement to have general legal effect (erga omnes). Unlike a sectoral collective agreement, a company collective agreement does not apply to all companies operating within a particular economic activity, but only to the organisation that negotiates it and to the employees included within its functional and territorial scope.
Its content may address different aspects of the employment relationship, including work organisation, certain remuneration systems, professional classification, working hours, the distribution of working time or specific measures for business adaptation. However, this regulatory capacity is not unlimited. A company collective agreement must comply with mandatory employment rules and the minimum rights recognised by applicable legislation.
The Strategic Value of a Company Collective Agreement for Organisations
The main advantage of a company collective agreement is the ability to adapt employment regulation to the organisation’s specific needs. Every company has a different reality. Its business model, internal structure, production processes, international presence or working systems may not fully correspond to the framework established by a sectoral collective agreement.
In these circumstances, an internal collective agreement can establish rules that are more closely aligned with the way in which the company operates. This adaptation can provide greater legal certainty, reduce uncertainty and facilitate more structured management of employment relationships.
However, negotiating a company collective agreement should form part of a medium- and long-term employment strategy. It should not be viewed solely as a tool for modifying certain financial conditions, but rather as an instrument for building a stable framework between the company and its workforce.
Negotiating a Company Collective Agreement: Legal Requirements Regarding Standing
A company cannot unilaterally establish its own collective agreement or negotiate it with any interlocutor. Negotiations must take place with employee representatives who have the standing required under employment legislation.
In accordance with Article 87.1 of Royal Legislative Decree 2/2015 of 23 October, approving the consolidated text of the Employees’ Statute, standing to negotiate company collective agreements on behalf of employees belongs to:
- The works council or employee representatives.
- Trade union sections, where they exist, provided that together they hold the majority of the members of the works council.
Public policy limitation: The absence of employee or trade union representation within the company prevents the negotiation of a statutory collective agreement. It is not legally possible to replace the absence of permanent legal representatives by appointing an ad hoc committee temporarily elected for the purpose of negotiation, as confirmed by the High Court of Justice of the Canary Islands in its judgment of 2 June 2016.
If a company wishes to have its own collective agreement, it must have permanent legal representation elected through an electoral process with all the applicable safeguards.
Company Collective Agreement and Sectoral Collective Agreement: Priority of Application and Limitations
The relationship between a company collective agreement and the applicable sectoral collective agreement is strictly regulated by employment legislation in order to prevent the deregulation of minimum sectoral conditions.
In accordance with Article 84.2 of Royal Legislative Decree 2/2015 of 23 October, approving the consolidated text of the Employees’ Statute (as amended on 22 May 2024 by BOE-A-2024-10235), a company collective agreement takes priority over a national, regional or lower-level sectoral collective agreement only in the following areas:
- Payment or compensation for overtime and specific remuneration for shift work.
- Working hours and the distribution of working time, shift work arrangements and annual holiday planning.
- Adaptation of the professional classification system to the company level.
- Adaptation of aspects of employment contract arrangements that the Employees’ Statute assigns to company collective agreements.
- Measures promoting shared responsibility and reconciliation of professional, family and personal life.
Critical limitation regarding overlapping collective agreements: Outside these specified matters, the principle of chronological priority under Article 84.1 of the Employees’ Statute applies. This means that a subsequent company collective agreement cannot reduce the salary conditions or maximum annual working time established in a higher-level sectoral collective agreement that remains in force, as determined by the Spanish Supreme Court (Roj: STS 3661:2025 · ECLI: ES:TS:2025:3661).
Matters That Can Be Regulated by a Company Collective Agreement
Within the applicable legal framework, a company collective agreement can regulate different aspects of employment organisation. These may include matters relating to:
- Professional structure and adaptation of the classification system.
- Work organisation and the implementation of new production systems.
- Certain working-time, shift and flexible working arrangements.
- Criteria for professional classification and workforce categorisation.
- Remuneration matters and salary supplements linked to company performance, within the applicable legal limits.
- Professional promotion systems and training plans.
The choice of matters to be negotiated should respond to the company’s actual needs. An effective collective agreement is not one that regulates the greatest possible number of issues, but one that establishes a clear, useful and organisation-specific framework.
The Importance of Good Faith During Negotiations
Good faith is one of the fundamental principles of collective bargaining, established in Article 89.1 of Royal Legislative Decree 2/2015 of 23 October, approving the consolidated text of the Employees’ Statute. This means that the company and employee representatives must participate in a genuine process of exchange.
The obligation to negotiate in good faith does not mean that the parties must necessarily reach an agreement. Negotiations may be properly conducted even where no consensus is ultimately reached. What matters is that there has been a genuine willingness to negotiate, with an exchange of information, consideration of proposals and a real opportunity for dialogue.
The courts have repeatedly emphasised that collective bargaining cannot become a mere formal or apparent procedure for imposing unilateral decisions, as analysed in the judgment of the National High Court of 28 September 2011.
Legal Risks of a Poorly Structured Company Collective Agreement
Although a company collective agreement offers significant opportunities, it can also create serious risks if it is not properly designed:
- Judicial challenge to the collective agreement: This is brought through the procedural mechanism established in Article 163 of the Labour Jurisdiction Act. If defects are identified in the constitution of the negotiating table, the signatories lack sufficient representativeness or mandatory legal provisions have been breached, the court may declare the statutory collective agreement null and void, as reflected in the doctrine of the Spanish Supreme Court (Roj: STS 2238:2026 · ECLI: ES:TS:2026:2238).
- Collective disputes: These may arise from conflicts between company and sectoral collective agreements or from the failure to apply minimum salary conditions.
- Individual monetary claims: Employees may bring claims for salary differences resulting from the incorrect application of the company collective agreement instead of the applicable sectoral agreement, as analysed by the Spanish Supreme Court in its judgment of 23 February 2016 (appeal).
- Link: Spanish Supreme Court (Roj: STS 3003:2025 · ECLI: ES:TS:2025:3003).
For this reason, the legal certainty of a collective agreement does not depend solely on the final signed text, but on the entire process that preceded it. Documentation of meetings, the information provided and the traceability of negotiations are decisive in the event of subsequent judicial review.
The Role of Human Resources in Negotiating a Company Collective Agreement
Human Resources departments play an essential role in preparing, negotiating and implementing a company collective agreement.
Before the process begins, HR should analyse the organisation’s current situation, identify its needs and coordinate business objectives with legal requirements. During negotiations, HR must ensure appropriate management of information and consistent communication with the parties involved.
After the agreement is signed, it will be necessary to ensure its proper implementation in order to avoid contradictory interpretations or disputes arising from its application. A collective agreement does not end with its signature. Its effectiveness depends on how it is integrated into day-to-day employment management.
Company Collective Agreements in International Groups
For international groups with a presence in Spain, a company collective agreement can be particularly relevant. Many multinational companies have global Human Resources policies that need to be adapted to the Spanish employment framework.
In these circumstances, the challenge is to find a balance between international corporate standards and the particularities of the Spanish collective bargaining system. The company must ensure that its internal policies are compatible with Spanish legislation and that any local adaptation complies with the legal requirements governing negotiation and implementation.
Good Practices for Negotiating a Company Collective Agreement
- Rigorous verification of standing: Ensure that the negotiating committee is constituted in compliance with the representativeness percentages required by Articles 87 and 88 of the Employees’ Statute.
- Planning and meeting timetable: Establish an organised negotiation plan and respond to proposals from employee representatives in a reasoned and written manner.
- Documentary traceability: Prepare detailed minutes of each negotiation session, signed by both sides, in order to demonstrate good-faith bargaining and the genuine exchange of proposals.
- Prior analysis of overlapping collective agreements: Assess the applicable sectoral collective agreement to ensure that the company collective agreement does not regulate prohibited matters or matters where it does not have priority of application.
The Company Collective Agreement as a Tool for Employment Stability
A company collective agreement in Spain can become a strategic instrument for organisations that need to adapt their employment framework to a specific reality. Its usefulness lies not only in the possibility of establishing specific conditions, but also in its ability to create an organised, coherent employment system aligned with the company’s business strategy.
However, its effectiveness will always depend on negotiations being properly structured, compliance with legal limitations and appropriate subsequent implementation. For companies, the real challenge is not simply to negotiate a collective agreement, but to build an employment framework that can be maintained and legally defended over the long term.

Frequently Asked Questions About Company Collective Agreements in Spain
What is a company collective agreement in Spain?
It is a statutory agreement with general effect (erga omnes) negotiated between a company and the duly authorised representatives of its employees, works council, employee representatives or trade union sections, regulating working conditions, employment and productivity within the organisation.
Can a company without employee representatives negotiate a company collective agreement?
No. In accordance with Article 87.1 of the Employees’ Statute and established case law, negotiating a statutory company collective agreement requires the involvement of permanent employee or trade union representatives. The temporary appointment of ad hoc committees for this purpose is not valid. These committees are reserved for consultation periods concerning specific collective measures, such as collective dismissals or substantial modifications to employment conditions.
Does a company collective agreement take priority over a sectoral collective agreement regarding salary?
No. Following recent legislative reforms, the amount of base salary and salary supplements is no longer included among the matters where company collective agreements have priority of application under Article 84.2 of the Employees’ Statute. Therefore, a company collective agreement must respect the minimum salary conditions established by the applicable higher-level sectoral collective agreement, unless the company collective agreement is more favourable to employees.
How is a company collective agreement challenged?
A challenge is brought before the Employment Courts through the procedural mechanism established in Article 163 of the Labour Jurisdiction Act. Proceedings may be initiated by the labour authority on grounds of illegality or detriment, by trade unions with sufficient presence within the relevant scope, or by third parties alleging infringement of their legitimate rights. A final judgment declaring the collective agreement null and void will have general res judicata effect and will render the collective text inapplicable.
