Spanish Unions Call General Strike as European Wave Highlights Differing Economic Costs

Spain’s major trade unions, Comisiones Obreras and Unión General de Trabajadores, have called a 24-hour national general strike for Wednesday to protest over living costs, wage levels, and public services. The nationwide walkout takes place 18 days prior to Spain’s scheduled snap general election on 29 November.

The Spanish protest reflects a broader wave of industrial action across the European Union following what preliminary figures from the European Trade Union Institute show was the highest year for strike activity in 2025 since 1991. France logged a national strike over living costs on 5 November, while Italy’s CGIL union has scheduled a general strike for 20 November, and Belgian trade unions have threatened coordinated action for late November.

Theoretical economic models based on Eurostat data show that a single-day strike involving one-fifth of the workforce costs Germany’s economy approximately €2.5 billion in lost output. Under the same calculation, daily output losses would reach €1.6 billion in France, €1.2 billion in Italy, and €930 million in Spain, where total annual economic output reached €1.69 trillion last year. Smaller economies face smaller absolute daily figures, with Belgium estimated at €350 million and Portugal at €170 million per strike day.

Central bank data indicates that single-day walkouts rarely translate into equivalent permanent losses to gross domestic product. Analysis by the Banque de France and the national statistics agency INSEE showed that pension protests in early 2023 reduced quarterly growth by 0.1 percentage points before economic activity rebounded by the same margin in the following quarter. While delayed production and rescheduled services recover over time, unrecoverable losses primarily affect hotel bookings, airline travel, lost wage income, and government tax revenues.

Economic researchers point to repeated labor disputes as a primary driver of long-term economic friction compared to isolated walkouts. Figures from the European Trade Union Institute show Belgium recorded 1,354,845 lost working days in 2025, representing 313 lost days per 1,000 workers. By comparison, the Netherlands recorded nearly 60,000 lost days across 23 strikes, while Germany’s Institute of Economic and Social Research reported 645,000 lost working days during the same year.

Financial markets have shown limited reaction ahead of the Spanish strike, with Madrid’s IBEX 35 stock index maintaining a 14.1 percent gain for the year at 19,742.5 points on Monday. Shares in Spanish airport operator Aena and hotel group Meliá Hotels International remain up 21 percent and 38 percent respectively over the year to date. Early turnout estimates in Spain will be derived from morning power consumption data from grid operator Red Eléctrica, ahead of the snap election on 29 November.
