300 pilots choke Antwerp-Bruges port

By late May, more than 40 vessels were sitting outside Antwerp-Bruges, waiting for permission to move. They could neither enter nor leave Europe's second-largest port because roughly 300 maritime pilots, organised by Belgium's ACOD public-sector union, had stopped work at a harbour that carries chemicals, car parts and perishable food through northern Europe (Port of Antwerp-Bruges).

There was no easy workaround. Belgium has no minimum-service law for its ports, and there is no pool of replacement pilots ready to step in. When the pilots stop, the port stops.

Maritime pilots are usually former merchant navy captains who have spent years learning the channels, currents and depths of a particular harbour. International rules require them to be on board large commercial vessels entering port (IMO).

That knowledge cannot simply be borrowed from elsewhere. A pilot certified for Rotterdam cannot be drafted in to cover Antwerp. The system is deliberately lean, with about 300 pilots serving Antwerp and Zeebrugge together. Economists call this chokepoint labour: a small group of workers whose specialised and irreplaceable role gives them power over a much larger system.

The pilots have used that position before. In November 2025, a similar walkout blocked 110 ships and forced three key locks to shut entirely (akm.ru). Even when pilots return, the backlog takes days to unwind because berthing schedules and tidal windows knock into each other. The May 2026 strike is at least the third major disruption in under a year.

The pension fight behind the picket line

The dispute at Antwerp is part of a wider Belgian union campaign against the government's pension reform. The new rules raise the retirement age to 67 and narrow what counts as a full working year. Under the reform, a worker must record at least 156 working days in a year for that year to count towards pension entitlement (tvl.be).

Anyone retiring early without meeting the new career-length rules faces a permanent cut in their monthly pension. Unions say that punishes people in physically demanding or irregular jobs, and particularly women, whose working lives are more likely to be interrupted by childcare or part-time work.

The government says pension spending is rising faster than the economy can carry and that reform cannot be avoided. After more than 18 months of rolling strikes across sectors, neither side has shifted enough to break the deadlock.

Who pays when ships wait

A ship stuck outside port can cost its operator tens of thousands of euro a day in idle charter charges. Those costs do not stay at sea. Carriers pass on delay surcharges to importers, importers push up prices for retailers, and smaller businesses without alternative routes or spare stock are left with the sharpest bill.

For perishable goods, the calculation is even more brutal. Delay means spoilage, and spoilage means the whole cargo can be lost.

The effects move quickly beyond Belgium. Antwerp is home to Europe's largest integrated petrochemical cluster, supplying raw materials to Dutch chemical plants and handling parts for German carmakers. Dutch unions have already flagged the disruption, pointing out that supply chains through Antwerp feed factories and distribution centres across the Netherlands, Germany and further afield (cnv.nl).

Rotterdam is not a simple substitute. The Dutch port has its own congestion problems, and moving freight overland from there is significantly more expensive.

All of this lands on a European shipping network already under pressure. Vessels are being rerouted around Africa to avoid conflict zones, adding weeks to transit times. Every fresh bottleneck at a destination port eats into the small amount of schedule slack left in the system.

Europe's unresolved contradiction

The EU's Critical Entities Resilience Directive treats ports as critical infrastructure, but its focus is on physical threats such as terrorism or natural disasters, rather than labour disputes (European Commission). Article 153(5) of the EU Treaty, which governs EU social policy, places the right to strike outside EU-level regulation.

That leaves the rules to national governments. Italy requires minimum port services during strikes. Belgium does not. There is no EU-wide mechanism to bridge the gap between protecting the right to strike and keeping critical trade infrastructure moving.

At Antwerp, those two commitments keep colliding. Until the law finds a way to reconcile them, 300 pilots with local knowledge no outside workforce can replace will retain leverage over a continental trade artery, and Europe's supply chains will keep paying for it.
