What does the strike mean for travellers and residents on 30 October?

Anyone who has booked a ferry between the islands on 30 October should allow extra time. The strike is announced for Friday 30 October 2026 between 13:00 and 15:00.

During that period, the union says cargo handling will stop in all Spanish ports of general interest. Atlántico Hoy explicitly names Las Palmas and Santa Cruz de Tenerife as affected.

Ferries due to dock or depart in that window could be delayed. Goods handling for supermarkets may also be held up.

Travellers should check directly with their ferry operator.

Why are the port workers striking?

The port workers want to stop civilian ports being used for military purposes. The Coordinadora Estatal de Trabajadores del Mar therefore rejects the EU Port Strategy adopted on 4 March 2026.

According to the union, this strategy promotes dual-use facilities in order to prioritise military mobility. The port workers fear civilian terminals will become logistics centres for troops and weapons.

According to Atlántico Hoy, the union warns that ports could become military targets as a result. Handling explosives also poses a risk to workers.

There is also a labour law dispute: the union says the Ley de Puertos allows Ministry of Defence freight to be excluded from regular port services. The Coordinadora sees this as a risk of outsourcing and job losses.

Which ports are affected by the strike?

According to Atlántico Hoy, the strike notice applies to all ports of general interest in Spain. These include the ports of Las Palmas on Gran Canaria and Santa Cruz de Tenerife.

An official list of participating Canary Island ports had not been published by Friday. According to Nueva Revolución, the international mobilisation covers more than 40 ports in the Mediterranean and Europe.

The form of the action is decided by the respective unions and national legislation. According to Diario Octubre, the underlying declaration was adopted in Istanbul in May 2026 by unions from more than 35 ports.

It calls for ports not to be used for weapons, ammunition, military equipment or troops. That is the common thread of the action.

Which questions remain open before the strike?

The main unknown is which Canary Island ports will take part: as of Friday 23 October 2026, this had not been confirmed. Strike times and minimum services for the Canary Islands had also not been officially set.

The available report from Diariodelpuerto names neither the affected Canary Island ports nor strike times or minimum services. No official resolution on minimum services for 30 October 2026 was found.

Whether ferries and essential supplies will actually be affected remains open. There is currently no evidence of long-term supply or price consequences.

Travellers should ask their ferry operator and the relevant port about confirmed timetable changes before departure. That way they will know early whether their connection is affected.

What is behind the international day of action?

The strike is part of an international mobilisation under the slogan "Contra la guerra y la militarización, puertos por la paz y por el trabajo digno". It stems from the III Reunión Internacional de Sindicatos de Estibadores in Istanbul in May 2026.

According to Progressive International, the unions are calling for more transparency about freight and the exclusion of weapons and military transport. They also demand better wages, permanent employment and stronger health and safety rules.

The Coordinadora also criticises the fact that maritime transport falls under the EU Emissions Trading System ETS. The union says this shifts cargo handling to non-European ports such as Tanger Med in Morocco or East Port Said in Egypt.

According to Observatorio EU-ETS, the market share of European ports in transhipment traffic fell from 51 to 26 percent. The union sees this as a threat to the connectivity of the ports of Tenerife and Las Palmas.

What further actions follow after 30 October?

The port strike is not the last mobilisation announced in Spain. A 24-hour general strike for affordable housing is announced for 11 November 2026.

According to Atlántico Hoy, this is backed by CCOO and UGT together with the Sindicato de Inquilinas and other groups. A doctors' strike is also under way in the Canary Islands.

For the port strike, 30 October remains the next fixed date. The sources do not indicate whether further actions will follow.

Anyone who has booked a ferry on 30 October 2026 should contact the operator. There is currently no guarantee of delays or cancellations.
