Strike, Court, or Negotiation Table: How Europe Resolves Labor Conflicts Through Mediation

When discussing mediation in labor relations, it is worth clarifying precisely what is meant, because three different concepts hide beneath this single term. The first is individual disputes between an employee and an employer, such as those regarding dismissal, unpaid wages, or discrimination. The second is collective disputes, where a trade union or another employee representative stands on one side, and an employer or an employer association stands on the other. The third is internal workplace conflicts between colleagues or between a manager and a subordinate, which often lack any formal legal claim but destroy a team no less than a lawsuit. This article is primarily dedicated to the first two, while I merely note the third, as it is closer to corporate and HR practice than to labor law.

In previous articles of this series, labor disputes were mentioned in passing. The article on GEMME noted judges specializing in labor law among the organization’s members, while the article on CMAP described internal corporate mediation with fee structures tied to company size. Now it is time to consider this field separately, as it operates under its own rules, and Europe demonstrates perhaps the greatest diversity of approaches here among all areas of mediation.

Why Labor Disputes Live by Their Own Rules

The best explanation for this distinct character is provided by the EU Mediation Directive 2008/52/EC itself, to which a dedicated article in this series is devoted. The Directive applies to cross-border civil and commercial disputes but explicitly excludes rights and obligations that the parties are not free to dispose of under the applicable law. In its preamble, the EU legislature clarifies that such non-disposable rights and obligations are particularly prevalent in family and labor law, explicitly naming these two sectors as examples. Thus, within the very text designed to create a common framework for mediation across the Union, labor law was designated as a realm where the use of mediation requires heightened caution.

The logic behind this reservation is clear to anyone who has worked with labor cases. A significant portion of employee rights—such as minimum wage guarantees, safety requirements, protection against discrimination, and mandatory notice periods for termination—has an imperative (statutory) nature. Consequently, parties cannot waive these rights even if both genuinely wish to do so. This does not render mediation impossible. 

Parties remain free to negotiate matters within their discretion, such as the terms and date of employment termination, compensation amounts, the wording of the severance rationale, reference letters, payment schedules, or future post-employment relations. However, a mediator in a labor dispute operates within a corridor of mandatory norms and must ensure the resulting agreement does not violate them—a boundary that is rarely necessary in purely commercial disputes between two corporations.

There is a second circumstance that is easily overlooked. The Directive applies exclusively to cross-border disputes, whereas the vast majority of labor conflicts in Europe are purely national in scope. As a result, labor mediation models were shaped not by Brussels legislation, but under the influence of local traditions of collective bargaining and social dialogue, many of which predate the directive by decades. Scandinavian conciliation services have operated since the first half of the last century, while the British ACAS has functioned since the mid-1970s. The 2008 Directive arrived in a world where labor mediation already possessed its own institutions, vocabulary, and internal logic, leaving them substantially unaltered.

Individual and Collective Disputes: Why They Are Different Worlds

To avoid confusion going forward, a clear line must be drawn between the two types of disputes. An individual labor dispute concerns a specific person and a specific employment contract. It is typically handled by labor courts, tribunals, or specialized commissions, where mediation serves to help negotiate the terms of ending the employment relationship or, far less frequently, preserving it. A collective dispute has a fundamentally different nature: it involves a group of employees acting through a trade union or another representative body, with the potential weapon in such a conflict being a strike.

Within collective disputes, European legal systems generally distinguish between disputes of rights and disputes of interests. A dispute of rights arises when the parties interpret an existing collective bargaining agreement differently, and it is resolved by a court or a specialized body. In Denmark, for instance, the Labor Court deals primarily with such disputes—specifically breaches of collective agreements—whereas conflicts of interests, meaning disagreements over the terms of a new agreement, are settled through negotiation, assisted if necessary by an official conciliator, or through industrial action. It is precisely in disputes of interests that mediation and conciliation play the most crucial role, because there is no existing legal norm for a judge to apply, and a new rule must emerge from a compromise.

The right to strike, upon which the entire logic of collective mediation rests, is recognized in most countries worldwide, although it is restricted or barred for certain professions with high societal impact. In France, for example, this applies to categories such as the police or the military. The presence of the strike as a last resort explains why collective disputes demand a completely different set of tools than individual ones: time works against everyone, and the cost of failure falls heavily on third parties, such as patients, passengers, and students.

A separate word should be said about terminology, which is particularly tangled in this field. The British ACAS consistently distinguishes between collective conciliation, mediation, and arbitration, offering mediation through an independent panel of mediators. In other countries, the terms “conciliation,” “mediation,” and “intervention” are used almost synonymously. Throughout this text, I use “mediation” in a broad sense, and where the distinction is fundamental, I explicitly note whether conciliation or a mediator’s proposal is being referred to.

The British Model: Voluntary, Yet with Mandatory Communication

For most European lawyers, the image of labor mediation is associated primarily with the British Advisory, Conciliation and Arbitration Service, universally known as ACAS. Operating since the mid-1970s, the Service is publicly funded, yet users—according to academic studies—value it precisely for the impartiality and professionalism of its conciliators. ACAS serves both domains—individual and collective disputes—and its practice clearly illustrates how differently a single institution operates across these two spheres.

In collective disputes, the ACAS approach remains strictly voluntary. How this works in practice was detailed in a previous article on how British mediators helped save British Airways from a major strike in 2010, so I will highlight only the core principle here. No British rule obliges a trade union or an employer to undergo conciliation before declaring a strike; nevertheless, according to the International Labour Organization (ILO), between 2013 and 2014 ACAS participated in over 850 collective labor disputes, achieving a resolution rate exceeding ninety percent. Interestingly, formal collective mediation accounts for a modest share of this work. According to research covering organizations with internal collective dispute resolution procedures, collective conciliation is requested most frequently (37 percent of cases), followed by arbitration (25 percent), while mediation conducted by an independent panel of mediators is chosen in only nine percent of instances.

The individual dimension tells a completely different story, one that resonates deeply with the themes explored in our article on the EU Mediation Directive. Since May 6, 2014, pursuant to the Enterprise and Regulatory Reform Act 2013, anyone intending to lodge a claim with an employment tribunal must first notify ACAS and undergo the Early Conciliation procedure. Without a certificate issued by ACAS following this step, the tribunal simply rejects the claim.

It is crucial to understand that what is mandatory is the initial contact, not agreeing to a settlement. The parties may refuse to engage in discussions, in which case ACAS issues the certificate and the case proceeds to the tribunal. Furthermore, during Early Conciliation, the limitation period for bringing a tribunal claim is paused—a mechanism strongly echoing the EU directive’s rule on preserving limitation periods during mediation. In the classification proposed by Giuseppe De Palo and colleagues for the European Parliament, four models are identified: fully voluntary, voluntary with incentives and sanctions, mandatory initial session, and fully mandatory. The British scheme formally falls into none of these categories, but in spirit it aligns most closely with the third, as it requires an individual to at least step through the door without compelling them to negotiate.

First-year operational figures demonstrate that the government’s objective was largely achieved. In April 2014, while the procedure remained voluntary, ACAS received approximately 1,000 notifications per week; in May and June, when it became mandatory, weekly notifications jumped to roughly 1,600. Only three percent of initial notifications in the first quarter came from employers, meaning the process was almost invariably initiated by employees. Overall, between April 2014 and March 2015, ACAS processed over 83,000 cases: 75 percent of employees and employers agreed to attempt conciliation, 63 percent of cases did not proceed to a tribunal, an additional 15 percent concluded with a formal settlement (documented via a COT3 agreement in the UK), and only 22 percent resulted in a tribunal claim. Of those that did reach a tribunal, over half were subsequently settled through ACAS. Recent reviews estimate that the service now receives well over 100,000 such notifications annually.

For readers following this series, a familiar pattern emerges. As in the case of CEDR, Britain achieved practical results not through a sweeping mandatory mediation law, but via an administrative gateway that alters human behavior without stripping individuals of their right to decide whether to settle. 

When Conciliation Attempts Become a Precondition for a Strike

The British and Dutch systems belong to those where workers may initiate strike action without a prior attempt at mediation. In the Netherlands, the services of the Social and Economic Council (SER) are similarly provided on a voluntary basis. However, this approach is far from universal.

Comparative studies of collective labor conflicts in Europe emphasize that in Spain, Portugal, and Belgium, an attempt to resolve the conflict through conciliation or mediation must precede any industrial action—that is, before a strike can be declared. Spain introduced these systems in the 1990s as a mandatory preliminary procedure for collective conflicts prior to declaring a strike or applying to court.

Behind this divergence lies the same debate seen in the history of Italian mandatory mediation. Proponents of mandatory procedures argue that strikes inflict collateral damage not only on the immediate parties but also on third parties and society at large, giving the public the right to demand that all negotiation avenues be exhausted. Opponents respond that forced negotiations turn mediation into a tick-box formality performed merely to obtain a procedural stamp. In the labor sector, however, there is a fundamental distinction from commercial disputes. An obligation to undergo a procedure almost never implies an obligation to reach an agreement; instead, it often serves as a cooling-off period that allows tempers to flare down and tests whether genuine room for compromise exists. In my view, this is precisely why mandatory steps in collective relations are met with far greater acceptance than in commercial matters.

Denmark: The Conciliator with the Power to Pause

Denmark presents perhaps the most fascinating structure of all, combining voluntary negotiation with formidable procedural instruments to pressure the parties. The central role is played by the State Conciliator, operating within the Conciliation Board (Forligsinstitutionen). In documents submitted by the Danish Government to the Council of Europe, it is stressed that the government has no influence over the State Conciliator during the renewal of collective agreements, a independence that forms the bedrock of party trust. According to research on Scandinavian practice, mediation in Denmark and Norway has long been an integral component of the collective bargaining system itself, rather than an add-on service.

A trade union intending to call a strike must provide advance notice to employers, usually via a first notice given at least fourteen days prior. It is during this window that the State Conciliator intervenes. If the Conciliator believes an agreement is attainable, they have the statutory right to postpone the strike twice, for up to fourteen days on each occasion—a total of up to 28 days. The second postponement requires a finding by the Board as a whole that the strike would have far-reaching societal consequences. Additionally, the Conciliator can require parties to resume negotiations on specific points, demand factual clarifications, and draft a formal settlement proposal (forligsskitse) that, under certain conditions, must be submitted to a vote by the membership of the respective organizations.

The most powerful tool in the Danish system is the technique known as the linking of proposals (sammenkædning). The Conciliator has the authority to combine several settlement proposals concerning different collective agreements into a single package. Voting then takes place on the entire package, preventing a dissatisfied minority in a specific sector from blocking an overall settlement supported by the majority. This is a striking example of how a mediation procedure can be embedded within the internal democracy of trade unions while offering protection against hold-out tactics.

The practical significance of this framework is well illustrated by real events. In 2018, when a major portion of the public sector—including healthcare, transport, education, and the prison system—was threatened by a combined strike and lockout, the Conciliation Board twice postponed the conflict for two-week periods, with the second delay announced after nineteen consecutive hours of negotiations. The very act of issuing a postponement is perceived in Denmark as a signal that the Conciliator views a deal as reachable.

At the same time, Danish experience candidly reveals the limits of conciliation. In 2021, members of the nurses’ union voted against a proposed collective agreement, and subsequently rejected a second proposal put forward by the Conciliation Board. The strike commenced on June 19 and lasted until August 27, when Parliament intervened by enacting legislation that imposed the very proposal formulated by the Board. This scenario is typical of Scandinavian countries, where the state legislates as a last resort if a conflict threatens vital public interests. Thus, even in the most sophisticated models, mediation does not eliminate the strike; it merely makes it less probable and less prolonged.

Portugal: State Mediation Without the Right to Choose the Mediator

The Portuguese model is intriguing due to a contrasting emphasis. In collective disputes, mediation is conducted by the Directorate-General for Employment and Labor Relations (DGERT), with services provided free of charge to the parties. The mediator is appointed directly by DGERT, and the parties have no right to choose the individual. According to ILO documentation, once the Directorate accepts a request for mediation, the parties can no longer refuse to participate, and the mediator is required to submit a formal proposal to the parties within thirty days of appointment.

Research covering cross-country practices notes that DGERT employs a specialized team of eleven specially trained mediators. According to staff members, applications originate predominantly from trade unions, as they are most frequently dissatisfied with existing terms. This arithmetic is noteworthy in itself, demonstrating that even within a system featuring mandatory participation, the initiative remains largely with the party seeking change.

For individual disputes, Portugal created a separate framework: the Labor Mediation Service (Sistema de Mediação Laboral), established under a 2006 tripartite protocol among social partners. Unlike collective mediation, this procedure is entirely voluntary, and parties may withdraw at any time. This dual structure—where participation is mandatory in collective disputes once a request is accepted, but voluntary in individual disputes—clearly shows that a single country can seamlessly combine different operational logics for different types of conflict. Belgium adopted a similar approach, assigning conciliation functions to specialized civil servants within a dedicated unit who blend multiple roles.

The Role of Trade Unions: Party, Initiator, and Ratifier

Trade unions appear so frequently in this narrative that a dedicated discussion of their role is essential. In labor mediation, trade unions fulfill at least three functions simultaneously, fundamentally distinguishing labor mediation from commercial practice.

The first function is representation. In Sweden, according to ILO data, the law grants trade unions formal standing to represent their members—as well as non-members covered by the collective agreement, encompassing roughly ninety percent of all workers—in the Labor Court. This framework positions the union as a natural mediator between the employee and formal court procedures, resulting in a vast number of individual grievances being settled before ever reaching a mediator. However, this privileged role for trade unions is not uniform across all jurisdictions. Where union influence is weaker, ILO experts observe that state labor administrations and dispute resolution agencies step in to fill the gap, providing fast and free services.

The second function is procedural expertise. Studies of British practice indicate that trade unions are generally far better informed about collective dispute resolution mechanics than employers; HR professionals on the employer side may not have handled such a procedure for years. The practical consequence is obvious: for a mediator handling a collective conflict, asymmetry of experience between the parties can prove as formidable an obstacle as asymmetry of interests, often requiring the mediator to spend significant time aligning both sides’ understanding of the process itself.

The third function—the most fascinating from a theoretical perspective—is ratification. The Danish example, featuring linked voting and two rejected nurse proposals, shows that an agreement reached between union leaders and management is not yet a final resolution. The ultimate word remains with the rank-and-file membership. The mediator, in essence, works on two levels simultaneously: between the two opposing sides, and within each side, bridging leadership and the general membership. This complexity is virtually absent in commercial mediation, where a representative’s authority is typically clearly delineated and the outcome is finalized by their signature.

Germany and France: Seeking the Neutral Inside the Enterprise

Germany offers a prime example of how labor conflicts can be resolved without trade unions acting as a direct party. At the enterprise level, the central role is played by the works council (Betriebsrat), operating under the Works Constitution Act. An employee has a statutory right to lodge a complaint with the works council if they believe they have been treated unfairly, and, as practical guides explain, a council member can support the employee or mediate between the employee and management.

For disputes between the works council and the employer, the law provides for a specialized conciliation committee known as the Einigungsstelle (regulated by Sections 76 and 76a of the Act). The committee comprises an equal number of representatives appointed by the employer and the works council, alongside an independent chairperson—most frequently a serving or retired labor court judge. If the parties cannot agree on the chairperson, the labor court appoints one. The costs of the committee are borne entirely by the employer. For a broad range of co-determination matters set out in Section 87, the decision of the Einigungsstelle can replace an unreached agreement and carry binding force, though a party contending that the committee exceeded its jurisdiction may appeal to the labor court. A textbook application is the social plan (Sozialplan) negotiated during mass redundancies, which, in the absence of mutual consent, can be bindingly determined through the conciliation committee.

To be rigorous regarding terminology, the Einigungsstelle is closer to a hybrid of conciliation and arbitration than classical mediation, as it issues binding decisions on certain matters. However, its value lies in the fact that before taking a vote, the committee continues negotiations between the parties, providing a mandatory institutional space to which the employer and the works council must return. It is also telling that the chairperson is typically a judge—someone who knows precisely how the case would unfold in a courtroom, a factor both sides weigh heavily.

The conciliatory element is built into the German judicial process itself. Prior to a hearing on the merits, the presiding judge conducts a preliminary conciliation hearing (Güteverhandlung), and the case can also be referred to a conciliation judge (Güterichter), who does not adjudicate the dispute but assists the parties in reaching a settlement. This mechanism, described in the German report submitted to the 26th Meeting of European Labor Court Judges, demonstrates how the court system itself can serve as the primary forum for conciliation.

France presents a picture defined more institutionally than statutorily. The CMAP center, which I covered in a separate article, offers internal corporate mediation with fee structures determined not by the claim value, but by company size measured by headcount. The registration fee is fixed at 500 euros, while professional fees range from 1,000 euros for companies with up to ten employees to hourly rates of 400–500 euros for organizations with over 250 staff. This approach is a direct response to the difficulty of assigning a monetary claim value to internal corporate conflicts, making organizational size a practical proxy for conflict scale.

Labor Court Judges and the Bridge to GEMME 

In the article on GEMME, I noted that the core membership of the organization consists of career judges across various jurisdictions, including civil, family, and labor law. The reason for this alignment should now be clearer. Labor courts are inundated with cases where a formal judgment rarely satisfies either party. An employee who wins a reinstatement claim may not actually want to return to the workplace, while an employer who wins may suffer reputational damage and a toxic workplace climate. In such cases, mediation offers what a verdict cannot: a conversation focused on the future. Judges who witness this gap daily naturally become its strongest advocates.

A comparison of the countries examined in this article reveals who steps in first across different systems. In Britain, it is the administrative service ACAS, standing at the gateway to the tribunal. In Denmark, it is the State Conciliator, armed with the power to pause industrial action when a strike looms. In Portugal, it is a government directorate appointing a mediator. In Germany, it is either a works council with a conciliation committee or a labor court judge conducting a conciliation hearing at the very outset of litigation. What all these models share is that entry into the procedure is facilitated by the state, the judiciary, or social partners, rather than by a private market of independent mediators as is typical in commercial disputes.

Ukraine: Two Tracks That Have Yet to Meet

Ukraine possesses a unique feature that is uncommon elsewhere: two parallel systems constructed at different times and according to different logics. The first governs collective disputes; the second addresses individual ones. 

Collective disputes in Ukraine are handled by the National Mediation and Conciliation Service (NMCS), established under the Law of Ukraine “On the Procedure for Resolving Collective Labor Disputes (Conflicts)” of 1998. The NMCS is a permanent state body funded by the national budget that facilitates dispute resolution through mediation and conciliation. The scale of its work is evident from its annual reports: the Service facilitated the resolution of 143 collective labor disputes in 2023, and 103 in 2024 (including three at the national level, four at the sectoral level, and 11 registered directly at enterprise level). Furthermore, to prevent disputes from arising, the Service placed 356 enterprises on its monitoring register in 2024. This preventive work closely mirrors the Danish model, where the conciliator intervenes before an open conflict erupts, rather than after a strike has already begun.

The martial law period warrants special attention. An analytical report by the NMCS covering the period from February 24, 2022, to February 29, 2024, notes that martial law significantly impacted social and labor relations; as of March 1, 2024, 75 disputes were in the process of being resolved. Concurrently, the Service engages in legislative drafting. In August 2022, work commenced on a draft law “On Collective Labor Disputes”—encompassing 56 drafting sessions—and the 2024 report confirms that the draft bill has been submitted to the Verkhovna Rada. Another notable milestone was the official approval of the professional standard for “Labor Mediator (Mediator in Labor Disputes),” intended to serve as the foundation for specialized training, alongside ongoing development of a “Labor Arbitrator” standard. This reflects the themes discussed in our article on the IMI, where mediator qualifications are verified through distinct specializations, demonstrating that the concept of labor mediation as a distinct profession is embedding itself in Ukraine’s regulatory framework. 

The second track—individual disputes—emerged much later. The Law of Ukraine “On Mediation” of November 16, 2021 (No. 1875-IX), which came into force on December 15, 2021, explicitly applies to employment relations. Simultaneously, the Labor Code of Ukraine was amended with Article 222-1, providing for the resolution of labor disputes through mediation; notably, this new provision was placed strictly within the chapter dedicated to individual labor disputes. The law also mandates that a court must stay proceedings for up to ninety days if the parties agree to enter mediation and submit a corresponding joint motion. Practitioners note that enterprise labor dispute commissions, while handling individual grievances, remain elected internal bodies rather than neutral, independent mediators.

Herein lies the gap highlighted by Ukrainian legal scholars. The placement of the mediation norm exclusively within the chapter on individual disputes means that the legislature effectively restricted the application of the general Mediation Act to this category, leaving collective disputes under the purview of the NMCS framework and its separate statutory base. In academic literature, this bifurcation has been directly criticized, with scholars emphasizing the need to extend general mediation mechanisms to collective disputes and harmonize terminology between the Mediation Act and labor legislation. In essence, the two tracks along which Ukrainian labor mediation travels have not yet intersected, and bridging them will be a primary task in the coming years. 

Viewed through the lens of European models, Ukraine’s framework already contains several familiar elements. A state agency empowered to intervene mirrors the Danish State Conciliator. Preventive monitoring of enterprises echoes ACAS’s early-stage conflict management. Court stays granted during mediation resemble the British suspension of limitation periods. What remains missing is the overarching unifying logic that integrates these components into a seamless system where an individual or a trade union knows precisely which door to enter at every stage of a conflict. 

The European experience demonstrates that while answers vary, the underlying questions are always the same. Who intervenes first: the state, the court, or the social partners? Is an attempt at conciliation mandatory, and if so, is it merely a gateway (as in Britain) or a cooling-off period (as in Denmark and Spain)? And who places the final stamp of approval: the union leader, the rank-and-file members, or parliament if negotiations fail? A country that answers these questions clearly and consistently will acquire not merely a statute on labor mediation, but a living, functioning practice. 

In gathering material for this article, what struck me most was that successful European models never relied on merely convincing parties of the theoretical merits of mediation. Instead, they relied on establishing a procedure that makes open conversation the simplest, cheapest, and least risky first step. The British gateway, the Danish pause, the German conciliation committee, and the Portuguese cost-free state mediator are designed differently, but they share a single core idea: dialogue must be made the default norm long before parties find themselves forced to choose between a strike and a courtroom. For Ukraine, as it builds its labor mediation architecture amidst war and profound labor market shifts, this is perhaps the most valuable lesson of all from the European experience.
