What mediation and arbitration do
Employment mediation helps parties develop a solution with an impartial person’s assistance. Arbitration entrusts a third party with a decision that is binding within the applicable legal framework. An internal negotiation meeting, formal mediation and an arbitral award do not automatically have the same effects. In occupational safety and health, they can help resolve disagreements about organisation, interpretation of agreements or implementation of safety improvements, without making the mandatory minimum level of protection negotiable.
Three questions should be separated: which risk needs immediate control, which disagreement can be settled and which procedure applies. A dispute over breaks during a shift may involve technical, collective and individual issues. Describing these separately helps identify a concrete solution and avoids treating every safety complaint as a dispute that must be referred to arbitration.
Protection cannot wait for agreement
The employer’s protection duties continue during negotiations. Where a serious and imminent risk exists, the measures and rights in Article 21 of Spain’s Occupational Risk Prevention Law (LPRL) apply; arranging mediation does not authorise continued exposure until the meeting ends. Technical control of the danger and processing the disagreement can proceed alongside each other.
Parties cannot validly waive rights established by mandatory legislation or made non-waivable by a collective agreement. For example, financial compensation does not legitimise working with a mandatory safeguard removed. They can discuss how to implement legally compliant solutions, which technically suitable alternative to adopt or how to verify an additional improvement. The agreement should state that distinction clearly, rather than replacing an existing duty to act with a promise of future action.
Identify the category of dispute
The initial analysis identifies the people affected, the claim and its basis: collective interpretation of an agreement, an individual claim, preventive organisation or a commercial dispute between businesses. Mentioning safety does not place all these matters under the same procedure. A contractual disagreement with a supplier about the cost of an adaptation is different from an employment dispute about protecting the people who use the equipment.
In Spain, Law 60/2003 excludes employment arbitration from its scope, and Law 5/2012 excludes employment mediation. Those exclusions mean the corresponding labour framework applies; they do not prohibit these mechanisms. A commercial arbitration clause should not be transferred to employees as though it removed their routes to redress. Where several fields overlap, distinct records and decisions should be defined so that they do not contradict one another.
Participation and legitimate representation
Prevention representatives and the safety and health committee have preventive participation and consultation functions. Their involvement contributes knowledge of actual work, but does not automatically give the committee standing to enter every collective agreement or arbitration submission. Who can act must be checked against the dispute, the affected constituency and the applicable instrument.
For collective disputes over interpretation or application of a collective agreement, Article 91 of the Spanish Workers’ Statute provides for prior involvement of its joint committee. Representatives need sufficient information and an opportunity to assess alternatives. Technical minutes can record facts and proposals without pretending that everyone attending has authority to bind third parties. Identity, capacity, constituency and the extent of each mandate are important case records, alongside the signature itself. Preventive expertise and legal standing are related but distinct requirements.
Choose the appropriate system
Spain’s Interconfederal Mediation and Arbitration Service (SIMA) operates under the VI ASAC agreement, which defines particular territorial, functional and personal scopes. It is not a universal service for every individual occupational safety dispute. The agreement covers certain collective disputes spanning autonomous communities and other expressly defined situations; regional systems or administrative services may be appropriate elsewhere. As checked on 8 November 2026, the SIMA Foundation states that the VI ASAC remains effective until 31 December 2028.
Before requesting intervention, check the collective agreement, territory, subject matter, standing and preliminary steps. The VI ASAC also permits preventive mediation at both parties’ request where circumstances could develop into a covered conflict. Preventing escalation can be useful, but does not allow a mandatory procedure to be skipped or powers to be attributed to an institution that does not possess them.
Prepare information and procedural safeguards
A useful case file separates established facts, technical assessments and proposed solutions. It may contain the relevant risk assessment, measurements, task descriptions, shift arrangements, related incidents and measures already implemented. It should identify missing information, responsibility for obtaining it and how its quality will be checked. An isolated photograph or uncorroborated complaint does not replace assessment, although it may justify investigation or an interim protective measure.
Impartiality, an opportunity to be heard and the ability to respond to the other party are important procedural safeguards. Document-access arrangements must respect information rights, medical confidentiality and applicable legislation. Medical histories should not be circulated to demonstrate an organisational disagreement. Nor should confidentiality provisions be used to obstruct legitimate action by the Labour Inspectorate or the courts. Necessary disclosure and appropriate restrictions should be defined rather than assumed.
Time limits and access to the employment courts
Spain’s Employment Jurisdiction Act (LRJS) generally requires a prior attempt at conciliation or mediation, subject to exceptions. These include certain social security matters, protection of fundamental rights and other expressly listed proceedings. Consequently, private mediation should not always be demanded before a person uses the competent legal route, and not every meeting fulfils the statutory preliminary requirement.
Article 65 governs effects on limitation and expiry periods and was amended in 2025. Formal filing, the meeting itself and the passage of the specified periods can affect the calculation differently. An internal conversation does not automatically suspend the clock. A tracking record should retain the date, procedure, filing evidence and next action validated by competent advice. A software reminder can support administration, but cannot determine which legal time limit applies or replace checking the current procedural rules.

Draft an enforceable preventive agreement
The outcome of mediation should identify the matter resolved, parties, commitments, responsible persons and verification conditions precisely. For prevention, separating the immediate measure, permanent solution and subsequent verification is useful. If a technical option is included, the agreement should explain what evidence establishes its suitability and what happens if new risks arise or working conditions change.
Legal effect depends on procedure and standing, not the document’s filename. Certain conciliation or mediation agreements constitute enforceable instruments under the LRJS; collective agreements can have the effect provided by the Workers’ Statute when its requirements are met. Ordinary internal minutes do not automatically acquire those effects. Routes to challenge agreements also exist: a signature does not make an unlawful or harmful clause valid. Operational clarity and legal validity therefore require separate, complementary checks before implementation.
Arbitration: define the question and boundaries
An arbitration submission should specify the question to be decided, the parties involved, governing framework and conditions of the intervention. Under the VI ASAC, arbitration normally rests on both parties’ express agreement, subject to specific situations provided for in collective agreements. It should not be described as universally voluntary in every context or as a general unilateral power of the employer.
An award is binding within its scope, but is not beyond legal scrutiny. The LRJS and Workers’ Statute provide challenges on specified grounds, such as deciding matters outside the submission, essential procedural defects or breach of mandatory rules, depending on the applicable procedure. A challenge is not an unrestricted rehearing of every substantive issue. Before accepting arbitration, the parties need to understand its subject, effects and review mechanisms. They cannot confer public powers on the arbitrator that they do not themselves possess.
Inspection, harm and liability
An agreement about preventive organisation does not replace the Labour Inspectorate or by itself eliminate possible liability arising from an accident. Workers and their representatives may approach the Inspectorate when they consider protective measures insufficient, under the LPRL. Where administrative or judicial proceedings are already open, relevant information must be preserved and lawful requests addressed.
Resolving a prospective disagreement must also be distinguished from settling a claim for harm already suffered. The ability to settle, representation and legal effects require specific analysis; adding a blanket waiver of every claim as a condition for correcting a risk is inappropriate. An agreement can document improvements and implementation responsibilities without claiming to certify absence of fault, erase earlier facts or automatically bind an insurer or third parties who did not participate. The same document cannot be assumed to resolve every consequence of an incident.
Hypothetical example: disagreement over shift arrangements
In a fictional example, an employer with several sites and employee representatives disagree about breaks and relief arrangements for physically demanding work. The prevention service analyses tasks, recovery and organisation; justified interim measures are implemented in the meantime. The parties establish whether the disagreement concerns application of the collective agreement and refer it to its joint committee where required.
If the competent mediation system accepts the dispute, evidence-based alternatives are presented: redistribution of tasks, sufficient staffing for relief and a verification timetable. A possible agreement identifies responsibilities, conditions and review following changes; it does not guarantee that one arrangement suits every person or job. If no agreement is reached, the outcome is recorded and legal routes remain available, while necessary protective measures continue. This is an organisational illustration, not an actual case or a mandatory technical solution.
Follow-up, indicators and document management
Useful indicators include time to bring the risk under control, completion of agreed measures, verification of their effectiveness and recurrence of the same disagreement. Counting signed agreements does not establish improved safety: documentary consensus can coexist with measures that were never implemented. A fall in complaints should not be rewarded where it coincides with reporting barriers or fear of retaliation.
For management supported by Sabentis, the case can be structured around documents, responsibilities, evidence and reviews, after checking the capabilities available in the actual configuration. This is an organisational proposal, not a claim that software resolves disputes or validates awards. Versions and dates should be retained, sensitive data restricted, and proposals, agreements, implementation and verification clearly distinguished. Closing the case requires evidence of the preventive outcome as well as the signed document; reopening criteria should address material changes and ineffective measures.
Frequently asked questions
Can an agreement allow work without a mandatory safeguard?
No. Non-waivable rights and preventive obligations do not disappear by agreement. Necessary measures must be taken while the disagreement is processed.
Does Spain’s general Arbitration Act govern employment arbitration?
Law 60/2003 excludes it from its scope. The relevant labour framework must be identified, including collective agreements, autonomous dispute-resolution agreements and the LRJS.
Does an internal meeting suspend the time limit for a claim?
Not automatically. Effects depend on the formal procedure and current limitation or expiry rules, which must be checked for the specific claim.
Does an award remove judicial scrutiny?
No. Challenges remain available on legally defined grounds. They are not an unrestricted rehearing of the entire substantive dispute.
