Airbus Spain Faces Indefinite Strike From 24 August After Workers Reject Pay Deal

Why Airbus Spain Is Heading for an Open-Ended Strike on 24 August

Airbus's Spanish operations are facing an open-ended strike from 24 August after the unions CGT, UGT and UTIL began proceedings on Friday to call an indefinite stoppage at every Airbus center in Spain. The move revives a labour conflict that had appeared close to resolution: a four-week strike led by the Sipa union ended when Sipa withdrew early this week, following a failed vote by workers on a preagreement negotiated with management and also backed by CCOO.

The rejected deal would have raised salaries by 5% in 2026 and a further 5% in 2027, added 0.5% a year to a fund compensating repetitive strain injuries and 0.5% a year for promotions, paid a €2,000 gross end-of-cycle bonus, and introduced a wage guarantee system. Airbus has said that text will not disappear and will remain 'the central element' in the mediation process it asked Spain's SIMA foundation to run, arguing that it represents months of work and 'very significant advances'.

The ballot defeat on 24 July exposed divisions inside the worker side. Sipa, which had convened the earlier strike, pulled back after the vote; UGT, which had urged an immediate return to negotiations, has now joined CGT and UTIL in pushing for an indefinite strike. The three convening unions together hold 45 of the 182 union delegate seats at Airbus Spain — 19 for UGT, 19 for CGT and 7 for UTIL — while CCOO holds 65, Sipa 40 and ATP 32.

The next three weeks will test whether mediation can bridge the gap before the strike date. If it cannot, the indefinite strike would be the first open-ended walkout in this conflict and would shut down all Airbus centers in Spain with no fixed end date.

The Rejected Deal, the Split Union Camp and the Mediation That Now Decides the Conflict

A Fragmented Union Map Complicates the Mandate

The strike notice highlights how fractured labour representation has become at Airbus Spain. CCOO is the largest force with 65 delegates (35.7% of 182), followed by Sipa with 40 (22%) and ATP with 32 (17.6%). The three unions that filed the indefinite strike notice — CGT, UGT and UTIL — together account for 45 seats, roughly 24.7%. That does not mean the strike lacks support, since Sipa had just led a four-week stoppage and UGT was already calling for stronger measures. But it does mean the unions are not speaking with one voice: a majority of elected delegates are in organisations that had either backed the rejected text or, in Sipa's case, withdrawn from the conflict after the failed vote.

Why the Rejected Text Is Still the Battleground

The substance of the dispute is pay and working conditions rather than a single symbolic demand. The rejected package combined a two-year 5% plus 5% general salary review, annual top-ups for the repetitive strain injury compensation fund and for promotions, a €2,000 gross end-of-cycle payment and a wage guarantee. Airbus has made clear it will treat that text as the baseline in mediation. For the unions calling the strike, the core question is why the workforce voted it down — the margin and the reasons were not disclosed in the announcements — and whether mediation can produce enough changes to win a second ballot. SIMA's role is therefore not to design a new deal from scratch, but to determine whether the existing package can be adjusted enough to be accepted.

The Calendar Leaves Little Room for a Fix

The sequence is tight. Airbus requested professional mediation through SIMA on the day before the strike announcement; the unions filed the indefinite strike notice on Friday; and the stoppage is scheduled for 24 August. With the previous four-week strike just ended and a no vote already on the record, the default outcome is escalation unless mediation produces something workers can accept. The practical choice for both sides is whether to use the time before 24 August to reopen elements of the wage package or to allow the dispute to move from a time-limited strike to one with no end date.

What an Open-Ended Stoppage Would Change

An indefinite strike is a different risk from the four-week action that just concluded. The announcement does not specify which programmes or delivery schedules would be affected, but the coverage of all Airbus centers in Spain means the stoppage would halt work across the company's entire Spanish footprint and create planning risk for suppliers and customers linked to those sites. None of this is certain: the SIMA mediation is already underway and could produce an agreement before 24 August. What the strike notice has done is set a hard deadline for the negotiation, with the failed preagreement still at the centre of the table.

What Airbus Management, Unions and Suppliers Should Do Before 24 August

For Airbus management and the unions in the SIMA process:

• Treat the 24 August strike date as the binding deadline for mediation. Airbus requested SIMA mediation the day before the strike notice was filed, so the process now has roughly three weeks to produce a result.
• Address the specific elements of the rejected text rather than restating them: the 5% reviews for 2026 and 2027, the 0.5% annual top-ups for the RSI fund and promotions, the €2,000 gross end-of-cycle payment and the wage guarantee were all rejected in the workforce consultation on 24 July.
• Prepare for a second consultative vote if a revised offer emerges. The previous preagreement failed at the ballot stage, so any mediation outcome should be tested with the workforce in a clearly explained vote before the strike starts.

For suppliers and customers exposed to Airbus Spain:

• Seek written continuity plans from Airbus covering the centers included in the 24 August notice. The four-week July strike already demonstrated that the unions are willing to sustain prolonged action.
• Avoid locking in revised delivery assumptions until the SIMA outcome is known; a settlement before 24 August would remove the strike risk entirely.

For employees and union members:

• Watch for any new consultation on a mediated text. The 24 July vote rejected the previous preagreement, so the next ballot — not the strike notice itself — is likely to determine whether the indefinite strike actually starts.
