Port Unions Stage Coordinated Strikes at 113 Ports in 22 Countries

Inside the Global Port Strike: What's Happening and Why

A coordinated wave of labour action is sweeping through global ports, with more than 25 unions staging strikes and demonstrations at 113 ports across 22 countries and territories. The scale marks a significant escalation from a February mobilisation that involved just 20 ports in seven countries, signalling growing momentum behind the campaign.

The action is primarily framed as opposition to military cargo shipments passing through civilian ports, but unions are also pressing demands for better wages, improved working conditions and protections against automation. Key gateways affected include Hamburg, Le Havre, Marseille, Genoa, Gioia Tauro, Piraeus, Tangier Med, Mersin and India's Nhava Sheva — a list that spans some of the world's most critical trade corridors.

France's CGT union has called a 24-hour walkout at approximately 24 ports and forecasts that up to 95% of national port activity could be halted. Italy has recorded a nationwide 24-hour ports strike running alongside a broader general strike affecting other transport sectors. In Greece, seafarers' unions have called 24-hour stoppages expected to disrupt ferry services at Piraeus, Rafina, Lavrio, Patras and Igoumenitsa.

Organisers estimate that participating unions represent workers handling roughly 40% of Mediterranean container traffic, with as many as 40,000 containers potentially delayed. However, the real extent of disruption remains unclear — some ports are staging demonstrations rather than halting cargo operations, and Genoa's port authority expects comparatively limited impact. No additional globally coordinated strike date has been announced, though separate actions loom: a possible November 1 strike involving 250 port watchmen threatens Los Angeles and Long Beach, and Italy faces another national general strike on November 20.

What the Port Strikes Mean for Supply Chains and Trade

Why the Mediterranean Is the Epicentre

The concentration of strike activity across French, Italian, Greek and North African ports places the Mediterranean at the heart of this disruption. Organisers claim participating workers handle roughly 40% of the region's container traffic — a figure that, if accurate, would represent a substantial choke point for goods moving between Asia, Europe and North Africa. The inclusion of Tangier Med, a critical transshipment hub connecting Africa and Europe, and Piraeus, a major gateway for Eastern European trade, amplifies the potential knock-on effects.

The Military Cargo Dimension

The campaign's stated focus on opposing war-related cargo handling through civilian ports introduces a geopolitical layer that distinguishes it from conventional wage disputes. This framing may attract broader public sympathy but also risks drawing ports into political controversies beyond labour relations. For context, civilian ports have historically handled military logistics under commercial contracts, and unions in several countries have periodically challenged this practice on ethical grounds.

Automation: The Underlying Tension

Beyond immediate wage demands, the unions' call for safeguards against automation points to a structural anxiety reshaping port labour globally. Port operators increasingly invest in automated container handling to boost efficiency and reduce costs, but unions view these technologies as direct threats to jobs. This tension is not new — similar disputes have played out at ports in the US, Europe and Asia — but the coordinated nature of this action suggests unions are attempting to build collective leverage against a common threat.

What the Disruption Means for Supply Chains

With up to 40,000 containers potentially delayed, shippers and freight forwarders face rerouting costs, inventory timing issues and potential demurrage fees. However, the actual impact remains uncertain: some ports are staging demonstrations rather than full stoppages, and Genoa's port authority expects limited disruption. The disparity between organisers' claims and on-the-ground reality means businesses should prepare for variability rather than assume uniform disruption across all 113 locations.

Looking Ahead: November Flashpoints

Two additional threats loom. A potential November 1 strike involving 250 port watchmen could disrupt Los Angeles and Long Beach — the largest US container gateway — though talks to avert the stoppage are ongoing. Italy's November 20 general strike adds another layer of uncertainty for European logistics. The absence of a new globally coordinated strike date suggests this wave may be a peak rather than a sustained campaign, but the November actions could extend disruption well into the fourth quarter.

How Businesses Should Respond to Port Disruption

Shippers and freight forwarders with cargo moving through Mediterranean or European ports should immediately assess which of their shipments are affected and identify alternative routing options before delays compound.

• Contact carriers and port agents to confirm whether specific ports on your supply chain are staging full strikes or demonstrations — the operational impact varies significantly by location.
• For cargo destined for French ports, expect up to 95% disruption per CGT forecasts; consider rerouting via Spanish, Belgian or Dutch gateways where possible.
• Monitor the November 1 situation at Los Angeles and Long Beach, where a strike involving 250 port watchmen could disrupt the largest US container gateway; talks are ongoing but contingency plans should be prepared.
• Build additional lead time into delivery schedules for Mediterranean-bound goods, factoring in potential delays of several days to a week for affected container traffic.
• For Italian operations, note the November 20 general strike date and plan around potential transport sector disruption.

Metrics to watch: Confirmation of whether the November 1 LA/Long Beach strike proceeds; official port authority statements on actual disruption levels versus union claims; any announcement of a new globally coordinated strike date.
