Greek seafarers and Italy’s formal strike notice widen Friday’s port action
Greece ties up its ships on Friday as the port protest passes 50 ports. Greek seafarers will keep ships docked at seven ports on Friday 30 October, including Piraeus, ot.gr reported on 27 October. Kuehne+Nagel now puts the wider dock action at “over 50 ports”. Italy has formally registered a 24-hour national port strike. Our view: the real disruption will be in Italy and Greece. Elsewhere, expect mostly rallies. Move Friday cut-offs forward now. Our prediction: by Wednesday 4 November, at least one major carrier will publish an advisory of delayed or skipped calls at Genoa or Gioia Tauro linked to the strike.
Greece ties up its ships as Friday’s port protest passes 50 ports. The damage will land in two countries
Greek seafarers will keep ships docked at seven ports on Friday 30 October. On 27 October, the Greek business site ot.gr opened its report with: “Ships are expected to remain docked on Friday, Oct. 30, at Greece’s main ports on account of a seafarers strike.” It named Piraeus, Rafina, Lavrio, Patra, Igoumenitsa, Elefsina and Rio-Antirrio.
It falls on the same day as a coordinated day of dock action that already includes Greek unions and Piraeus. Kuehne+Nagel now counts more than 50 ports in it. Unions in several countries planned the day to protest arms shipments through civilian ports.

Here is our view. The headline count overstates the risk for most lanes and understates it for two countries. Italy and Greece are where cargo will actually stop. Hamburg, Oakland and Veracruz look like solidarity, not shutdowns. Forwarders should plan around that split instead of reacting to the number 50.
What is confirmed for Friday
Start with Greece. According to ot.gr, the seafarers’ main demands include “a 12% increase in pay under collective bargaining agreements”. They also want dangerous waters, such as war zones, formally designated as dangerous maritime areas. Their other demands are better crew staffing, a seven-hour working day and a doctor on board ships, citing risks from armed conflicts.
Shore staff are also taking part. The Federation of Permanent Port Employees of Greece has called a three-hour stoppage from 10:00 to 13:00. The Piraeus Labor Center plans a 24-hour strike and a 10:00 rally in the city’s Municipal Theater Square. The Panhellenic Union of Merchant Marine Sailors will gather earlier, at 9:15, in the Agia Triada area of Piraeus. All of this comes from ot.gr’s 27 October report.
Then the wider picture. Kuehne+Nagel’s customer advisory, dated 26 October, says: “On 30 October, an industrial action is set to take place at over 50 ports across Europe, the Mediterranean and other regions.” It names Tangier, Marseille, Piraeus, Gioia Tauro, Genoa and Mersin. It says Germany’s ver.di union plans to join at Hamburg. Citing Splash247, it says support has been reported from ILWU Local 10 in San Francisco and Oakland, and it says dockworkers at Veracruz in Mexico plan to join. Its Italian list adds Livorno, Trieste, Civitavecchia, Ancona and Ravenna.
The most important line for Italy is this one: “The Italian transport ministry has formally registered a nationwide 24-hour port workers’ strike for 30 October.”
Kuehne+Nagel’s own caveat matters just as much: “The effect on port operations is expected to differ by location.” It says some ports face walkouts and others will see demonstrations rather than full stoppages.
Why we think Italy and Greece carry the risk
Our reasoning is about legal standing and depth of support.
In Italy, a registered national strike is not a rally. It is a formal 24-hour stoppage that terminals and carriers must plan around. Italy also has the most named ports. Ports Europe, citing Shipping Italy, lists eight: Ancona, Civitavecchia, Genoa, Gioia Tauro, Livorno, Ravenna, Salerno and Trieste. Gioia Tauro is a transhipment hub, where boxes move between big mainline ships and smaller feeder ships. If one call slips there, the connecting feeders slip too.
Ports Europe also reports that the Italian union USB has widened its action into a general strike. Its private-sector transport group is backing the port action. That makes it more likely that trucking and rail around the ports will be thin on Friday as well.
In Greece, the action hits ships and shore staff at the same time. The 10:00 to 13:00 stoppage is short. But a 24-hour strike called by the Piraeus Labor Center, plus seafarers refusing to sail, can cost more than a single shift. Several of the named ports, including Patra, Igoumenitsa and Rafina, are mainly ferry and ro-ro (roll-on, roll-off) ports. Patra and Igoumenitsa are the main ferry gateways from Greece to Italy. That means trailer freight on the Adriatic, and to the islands, is exposed as well as containers at Piraeus.
Outside those two countries, the evidence points to protest more than paralysis. Ver.di plans to join at Hamburg, and support has been reported at Oakland. Neither amounts to a declared stoppage in the advisory we read. We would not re-route on that basis. We would watch for updates on Thursday.
The unions say the ports involved handle about 40% of Mediterranean container activity, Ports Europe reports. That is the unions’ own figure, not an independent measure. Treat it as a measure of ambition, not of Friday’s likely disruption.
What happened last time
This is the campaign’s second coordinated international day. The first gives a useful guide to what Friday may look like.
On 6 February 2026, dockworkers shut down 21 ports across the Mediterranean, including Bilbao and Tangier, In These Times reported in July. The Maritime Executive reported on 6 February that USB’s 24-hour strike blocked container and ro-ro terminals in Genoa. The blockade backed up road and rail traffic. The union reported a 78% stoppage at La Spezia. It also reported a broad impact on intermodal operations out of Trieste, the rail and road links that carry boxes inland, reaching Austria and Germany.
Ships felt it too. According to union reports carried by the Maritime Executive, Zim Virginia was holding off Livorno. Zim New Zealand held at Fos-sur-Mer after being scheduled for Genoa. Zim Australia held at the Koper anchorage in Slovenia after being due at Venice and Ravenna. MSC Eagle III was reportedly diverted toward Koper. Most of these details came from the union and were not independently verified. Still, the pattern is clear. Italian calls slipped, and ships waited or moved to the nearest port that was working.
The campaign has grown since then. In February, 21 ports were shut. By late July, the unions said they represented workers at 40 ports, according to In These Times. Now Kuehne+Nagel counts more than 50. The aims have also widened, from arms shipments alone to the automation of ports and, in Italy, limits on the right to strike, Ports Europe reports.
The Italian roots go back further. During Italy’s general strike of 22 September 2025, dockers at Civitavecchia walked off and shut their port. They then learned that workers in Livorno and Genoa had done the same, In These Times reported. Riccardo Petrarolo, who sits on USB’s national coordination body for Italy’s ports, described it: “They were saying the exact same thing was happening at the other harbors.” Italian dockers have now stopped work at least twice in just over a year.
What forwarders should do this week
These are our recommendations, based on the facts above.
First, list every container due to gate in (be delivered to the terminal) or discharge on Friday at Genoa, Gioia Tauro, Livorno, Trieste, Ravenna, Ancona, Civitavecchia, Salerno or Piraeus. For exports, ask the carrier whether Friday’s cut-off (the last time a box can be delivered for a sailing) moves to Thursday. Push to get boxes in early. For imports, expect discharge to slip a day or more, and tell consignees now.
Second, raise charges before the strike, not after. Demurrage is the fee for leaving a box at the terminal. Detention is the fee for keeping the carrier’s box too long. Ask carriers in writing whether they will add free days for a declared strike day. Some will. Many will only do so if asked before the event.
Third, watch transhipment. Cargo routed through Gioia Tauro or Piraeus to smaller Mediterranean, Adriatic or Black Sea ports can miss its feeder connection. A one-day stop at a hub can turn into a week’s delay at the final port if the next feeder sails without the box.
Fourth, check ro-ro and ferry bookings between Greece and Italy, and to the Greek islands, for Friday and Saturday. Trailers may be held on the quay.
Fifth, keep an eye on Marseille-Fos, Tangier and Mersin. All three are on the named list. In February, at least one diverted ship ended up at Fos. If Fos also stops, the nearest alternatives for Italian cargo narrow to ports such as Koper.
On cost, we do not expect a one-day stoppage to move Mediterranean spot rates. The likely cost is in extra handling, storage charges and missed connections, not in freight rates.
Our prediction
Our prediction: by Wednesday 4 November, at least one major carrier will have published an advisory of delayed or skipped calls at Genoa or Gioia Tauro linked to the 30 October strike. We expect Italian terminal and gate backlogs to take two to three working days to clear, so they will run into the week of 2 November. We also expect the unions to call a third day of action before the end of Q1 2027, given how much this campaign has grown since February.
