ACAS vs. Strike: How British Mediators Saved British Airways in 2010

In November 2009, British Airways CEO Willie Walsh made a decision that triggered one of the longest and most destructive labour disputes in British aviation history. Without consulting the union, he reduced cabin crew numbers on flights — a move dictated by the recession and the airline’s catastrophic losses. The Unite union responded with a strike ballot. Thus began nearly two years of conflict that cost the company over £150 million, 22 strike days, and reputational damage that defies easy quantification. And which ultimately ended not in a courtroom, but at a negotiating table — thanks to an institution little known in Ukraine: the Advisory, Conciliation and Arbitration Service, or simply ACAS.
This case is more than a chronicle of a labour dispute. It is a detailed illustration of how an effective system of mediation in labour conflicts works, why it succeeds even in the most bitter confrontations, and what a Ukrainian equivalent of such a model might look like. But to understand why mediation ultimately worked, one must first understand why it failed for so long — and what made this conflict so difficult to resolve.
British Airways 2010: A Chronicle of the Crisis That Could Have Destroyed the Company
To understand why mediation in this case was so difficult, it is worth tracing the chronology of the conflict — because by the time ACAS was able to truly influence the situation, both sides had already travelled a long road of mutual escalation, legal manoeuvres, and public accusations.
At the start of 2009, British Airways was in an extremely precarious financial position. The global recession had crushed demand for air travel. The company, long a symbol of British commercial pride, was approaching losses in the hundreds of millions of pounds. Walsh, regarded as a tough and effective manager, decided to act decisively: reduce the number of flight attendants per flight, freeze wages, and revise working conditions. He did so unilaterally, without reaching agreement with Unite — the union representing approximately 12,000 cabin crew members.
For the cabin crew, this decision was not merely a deterioration in working conditions. It became a symbol of contempt for their rights. Unite held a ballot among its members — and the result was unambiguous: the majority supported strike action. But BA immediately went to court, claiming the union had breached ballot procedures. A court in December 2009 blocked the strike. This ruling only deepened the anger: the union felt that management was using legal technicalities to strip workers of their right to lawful protest.
February 2010 brought a fresh ballot — this time procedurally impeccable. March 2010 brought seven days of strikes, which cost the company up to £45 million. But no less destructive was what followed: BA announced the withdrawal of travel perks from all cabin crew who had participated in the strike. For people who had spent years proudly enjoying this privilege and passing it on to their families, it became a personal affront. The conflict ceased to be purely economic — it acquired an emotional dimension that made compromise far more difficult.
May and June 2010 brought a new series of five-day strikes. ACAS attempted to organise negotiations, but they collapsed for several reasons. First, representatives of the hard-left Socialist Workers Party physically disrupted one of the sessions. Second, Unite leader Derek Simpson was caught using an electronic device to stream closed-door talks live to union supporters. This was a flagrant violation of the confidentiality principle upon which any mediation process depends. Trust between the parties fell to zero.
The public rhetoric of both sides left no room for compromise. Walsh told journalists that Unite had “failed to paralyse British Airways” and that he had no intention of yielding. “This is a question of the airline’s future viability,” he repeated. Unite’s deputy general secretary Len McCluskey accused management of a “bunker mentality” and claimed that BA’s real goal was not to cut costs but to “destroy the union.” Every public statement made retreat increasingly painful. By the end of June 2010, the total number of strike days had reached 22, and BA’s losses for the financial year stood at £531 million.
But the conflict had another dimension that made it especially difficult to resolve: it unfolded against a backdrop of massive external shocks. In April 2010, the eruption of Iceland’s Eyjafjallajökull volcano closed European airspace for six days and cost BA approximately £100 million in additional losses. The company was fighting on two fronts simultaneously — against the union and against nature. In these circumstances, BA’s management was even less inclined to make concessions: every pound saved through new working conditions was a matter of survival.
It was this combination of factors — personal grievance, public rhetoric, legal combat, external losses, and collapsed negotiations — that explains why the conflict lasted so long and why ACAS required so many attempts before its intervention bore fruit.
ACAS as an Institution: Why Both Sides Trust It
It is precisely in this context that the role of ACAS proves especially valuable — and instructive for understanding what an institution of mediation in labour disputes should look like.
ACAS — the Advisory, Conciliation and Arbitration Service — is an independent public body of Great Britain, founded in 1974 in the wake of the mass labour conflicts that swept the country during that period. Its mission is simple and clear: to prevent and resolve labour disputes. The organisation is state-funded but legally independent of the government, employers, and trade unions. It is precisely this independence that is the key to its authority: neither side can accuse ACAS of lobbying for another’s interests.
But independence is only one component of trust in ACAS. Equally important is competence. Over decades of work, the organisation has accumulated unique expertise in labour relations: its specialists understand sectoral specifics, grasp the psychology of negotiations, and have experience handling conflicts of every scale — from local disputes at individual enterprises to nationwide confrontations threatening entire sectors of the economy. This reputation has accumulated over years and constitutes an independent asset that encourages parties to agree to participate in the ACAS process even when they do not trust each other.
ACAS has no power to compel parties to reach an agreement. It cannot oblige anyone to sit at the negotiating table or accept a particular outcome. But it can offer a neutral venue, experienced facilitators, and — critically — confidentiality. Negotiations involving ACAS are not public. Meeting places are not announced in advance. This allows parties to speak frankly without fearing that every concession will immediately become a newspaper headline or be used against them in court.
In the BA case, this was of critical importance. Both parties were under colossal public pressure. BA — from shareholders, passengers, and a government that openly urged the parties to reach a settlement. Unite — from its own members, some of whom had been dismissed or penalised for striking and who demanded protection. Any public concession would have been seen as betrayal: Walsh could not “surrender” to the union in front of shareholders, while Unite’s leaders could not agree to terms that members would interpret as capitulation. ACAS provided a space where solutions could be sought without public capitulation — and this was no less important than any specific proposal it placed on the table.
It is also worth noting how ACAS approached this conflict in terms of its choice of role. At different stages, the organisation acted in different capacities. Initially — as a venue for conciliatory negotiations: ACAS simply provided premises and a neutral environment, without imposing its own vision of a solution. Then, in the summer of 2010, when talks reached an impasse, ACAS chair Peter Harwood personally put forward new proposals and initiated a fresh round of negotiations — the organisation shifted from passive facilitation to active conciliation. Finally, as part of the ultimate agreement, ACAS took on the role of arbitrator in the cases of dismissed and penalised workers, with its decisions agreed by both parties to be binding.
This flexibility — the capacity to move from the role of facilitator to active conciliator to arbitrator depending on the needs of the situation — is one of ACAS’s greatest strengths and substantially distinguishes it from an ordinary judicial or administrative process, where the body’s role is rigidly fixed in advance.
It is precisely this multi-layered role of the mediator — simultaneously facilitator, conciliator, and, when necessary, arbitrator — that I examine in detail in my book Mediation: Ukrainian Experience and European Choice, also available in e-book format. This is not a theoretical survey of concepts, but a practical guide: it contains specific tools for working with each stage of a conflict and step-by-step algorithms for choosing the mediator’s role depending on the parties’ readiness — so that the correctly chosen format of mediation becomes the decisive factor. The book is written so that it can be opened in the middle of difficult negotiations and yield an answer to a concrete question.
The Mechanics of the Agreement: What the Union Proposed, and What BA Accepted
By autumn 2010, new figures had entered the conflict — and this proved decisive. Len McCluskey replaced Tony Woodley as Unite general secretary. Keith Williams replaced Willie Walsh as BA’s chief executive. Both new leaders arrived without personal grudges or public commitments that would have complicated compromise. One participant in the negotiations later observed that a “wind of change” was felt in the company — and this was not empty rhetoric.
McCluskey met Williams privately several times, outside formal negotiations. He later publicly described the new BA director as “strong, courageous, and brave” — a compliment that, in the context of two years of confrontation, sounded like a serious signal. “I was convinced that he wanted an honest negotiated settlement,” McCluskey said. This personal sense of trust in the other side’s intentions is one of the most important factors that makes mediation possible: without the basic conviction that the opponent also wants to reach agreement, no procedural mechanism will help.
In October 2010, ACAS organised a new meeting, still including Walsh and Woodley. Sources close to the talks reported “substantial progress.” Unite submitted fresh peace proposals to BA. One of the key signals was that the union removed the question of crew numbers from the negotiating agenda — effectively acknowledging the structural changes BA had introduced at the outset of the conflict. This was an important concession that allowed both sides to focus on what was actually blocking the agreement: the fate of penalised strikers and the question of travel perks.
It was precisely these two issues that formed the heart of the final negotiations — and they perfectly illustrate the difference between positions and interests, which is central to mediation theory. BA’s position on the perks was: “We grant them to those who demonstrate loyalty to the company.” Unite’s position: “Withdrawing the perks is a punishment for exercising the lawful right to strike.” Both positions were incompatible. But the interests of the two parties were entirely compatible: BA needed symbolic recognition of its managerial authority; Unite needed rehabilitation for its members. Finding a solution that satisfied both interests was the mediator’s task.
The agreement ultimately reached contained several key elements. BA agreed to restore travel perks for all cabin crew who had taken part in the strikes — a matter of principle for the union, since the withdrawal of those perks had been experienced as collective punishment for exercising the right to strike. However, restoration came without seniority rights in seat allocation — a small detail that allowed BA to save face by formally not abandoning the principle of differential treatment between those who had struck and those who had not.
In addition, the company offered a two-year pay deal: salary increases of up to 4% in the first year and 3.5% in the second, tied to productivity improvements. The cases of dismissed and disciplinarily penalised workers — over 100 individuals, including 14 who had been dismissed — were referred to ACAS for determination, with its rulings recognised as binding on both parties. This solution was elegant: it removed the most painful individual cases from the field of public battle and handed them to an independent body that both sides trusted.
For its part, BA received from Unite formal acknowledgment that the structural changes to cabin crew operations were permanent. This meant the union was abandoning any claim to return to pre-crisis crew staffing standards — the very issue from which the entire conflict had begun. The company also secured agreement on the “modernisation of industrial relations” with the crew — language that in practice meant a commitment by the union not to repeat such conflicts in future.
Symbolically important was the reaction of one participant in the union representatives’ meeting at which the terms were discussed. Duncan Holley — himself one of those dismissed by BA during the strikes — said the company had taken “brave steps” and the union must respond in kind. This remark precisely captures the essence of what had happened: the agreement became possible not because one side had broken the other, but because both had found the courage for mutual bravery.
McCluskey called the deal “fair” and declared: “We always said this dispute could only be resolved through negotiation, not confrontation or litigation. And that is exactly what happened.” Unite members voted to accept the agreement. A two-year war was over.
The ACAS Model as a Template for Labour Mediation in Ukraine
The BA–Unite conflict ended with an agreement that suited both parties. But the most important lesson of this story lies not in the details of the agreement, but in the role that the institution of mediation played in achieving it. And it is precisely this lesson that is most relevant for Ukraine.
In Ukraine, labour disputes are traditionally resolved through one of two channels: either through the courts or through public pressure. Both options are costly, time-consuming, and destructive to relations between employers and employees. A court delivers a ruling, but does not restore trust. Public exposure provides momentum, but deepens the divide. And in both cases, the underlying question that sparked the conflict often remains unresolved — or is resolved in conditions that make further cooperation impossible.
It should be acknowledged that Ukraine does have certain mechanisms for reconciliation in labour disputes. The National Mediation and Reconciliation Service (NMRS) formally performs functions similar to those of ACAS. In practice, however, its effectiveness remains limited for several reasons: insufficient institutional independence, a weak culture of trust in mediation bodies from both employers and unions, and — not least — the absence of a tradition of voluntary participation in mediation processes before a conflict escalates into open confrontation.
The ACAS model offers concrete benchmarks for improving this system. The first and most important element is institutional independence that is real, not merely declarative. ACAS does not answer to the government’s current political interests, does not depend on individual employers, and does not represent unions. This independence is not merely a principle — it is the practical foundation of trust without which mediation is impossible. The second element is process confidentiality. Publicity forces parties to play to the gallery rather than seek solutions. Any effective system of labour mediation must guarantee that what is said at the negotiating table will not become a weapon in the public struggle.
The third element is role flexibility. ACAS can be facilitator, conciliator, or arbitrator depending on what is needed at a particular stage. This flexibility allows adaptation to the dynamics of a conflict rather than imposing a rigid procedure upon it. In the BA case, ACAS changed its approach several times — and each time it corresponded to the real needs of the situation. The fourth element is the binding force of arbitration decisions on specific issues when the parties agree to this. This gives the mediation process genuine authority without compelling participation: the parties themselves decide which questions they entrust to an independent arbitrator — and this choice is their own decision, not one imposed from outside.
The fifth element, often overlooked, is the preventive function. ACAS works actively not only when a conflict has already exploded, but at early stages of tension: it conducts training for employers and unions, publishes recommendations on best practices in labour relations, and helps companies build internal dispute-resolution mechanisms. This is an approach in which mediation is not an emergency measure, but part of the culture of labour relations. It is precisely this culture that Ukraine lacks most of all.
For Ukraine, where labour legislation remains imperfect and the culture of negotiation between employers and unions underdeveloped, the introduction of an effective institution modelled on ACAS could radically transform the situation. This is especially relevant in the context of post-war reconstruction, when large-scale restructuring of the economy will inevitably sharpen the contradictions between employers who need flexibility and workers who need protection. In these conditions, effective mediation in labour disputes is not a luxury, nor an alternative for those who wish to avoid litigation. It is a systemic necessity.
The experience of ACAS demonstrates that mediation in labour disputes is neither a concession by the weak to the strong nor a way of evading accountability. It is a mechanism that allows both parties to receive more than they would have obtained through a court or a strike. BA preserved the structural changes it needed for survival. Unite preserved the rights of its members and restored the perks they considered their own. And both parties emerged from the conflict with the possibility of continuing to work together — which in a business where employer and union are condemned to coexist for years is no less important than any specific concession at the negotiating table.
Conclusion
The British Airways–Unite conflict lasted nearly two years, passing through the courts, mass strikes, public accusations, collapsed negotiations, and personal grievances. It could have ended in the airline’s bankruptcy or the union’s complete defeat. Instead, it ended in agreement — imperfect for each party, but acceptable to both and one that allowed the company and the union to move forward.
Why was this possible? Not because one side proved stronger or wiser. And not because external circumstances suddenly improved. It became possible through the convergence of several factors: a change of leaders who were free from the burden of personal confrontation; the willingness of both sides finally to separate the essential from the secondary; and the existence of an institution that could provide a neutral venue, confidentiality, and active support in the search for a solution when the parties finally demonstrated readiness to reach agreement.
ACAS did not save British Airways. That was done by the people who ultimately found the will to compromise. But ACAS created the conditions in which that will could be realised — and did so consistently, repeatedly, in different formats, without surrendering after each successive collapse of talks. That is the essence of effective mediation: not to replace the parties’ will to reach agreement, but to make it possible when it finally emerges. And to build a system in which that will emerges earlier, rather than after two years of destructive confrontation.
