Between October 2024 and early 2026, dockworkers or the truckers feeding them walked off the job on
three continents. The East and Gulf Coasts of the US shut down for three days. Vancouver, Prince
Rupert, and Montreal all stopped moving containers within the same twelve months. Rotterdam, Antwerp,
Hamburg, and Bremerhaven are still absorbing the aftershocks. None of it was unpredictable. Every one of
these disputes had a visible run up measured in months.
This isn’t a piece about whether dockworkers or truckers were right to walk out, or whether the wage
increases they won were fair. It’s about a pattern that shows up regardless of which side of any given
dispute you find sympathetic: the disruption always lands on cargo owners who had no seat at the
negotiating table and, often, no idea the contract expiration was coming.
Three Regions, Three Different Mechanisms
North America: The Contract Cliff
The October 2024 ILA strike that closed 36 US East and Gulf Coast ports, handling roughly 43 percent
of US containerized imports, was not a surprise to anyone tracking the master contract’s expiration
date. Automation and a 77 percent wage demand over six years were public sticking points for months
before the walkout. The strike itself lasted three days before a tentative wage deal, but full
settlement, a contract now running through September 2030, took until January 2025 to finalize.
Canada saw the same mechanism twice in one year: a 13 day strike at Vancouver and Prince Rupert,
followed weeks later by a lockout at the Port of Montreal, each time requiring the federal labor
minister to intervene directly to force operations back.
Europe: Disruption Layered on Disruption
Rotterdam, Antwerp, Hamburg, and Bremerhaven entered 2025 already dealing with alliance restructuring
and record low inland water levels affecting barge traffic. Strikes since April added roughly 15
percent capacity loss on top of that from crane refurbishment delays, pushing container dwell times
past eight days at the worst affected terminals, the most sustained port congestion in the region
since the pandemic. A strike that would have been absorbable on its own became compounding when it
landed on a system that had no slack left.
Asia: A Different Chokepoint
Asia’s largest terminals have not seen dockworker strikes on the scale of North America or Europe in
this period. The disruption there has tended to arrive one layer upstream, in trucking: cargo truckers
in South Korea have repeatedly blockaded access to the Port of Busan during broader labor disputes,
leaving the terminal itself fully staffed while nothing could physically move in or out. The outcome
for a cargo owner, a container that doesn’t move, looks identical regardless of which layer of the
chain the walkout happens in.
The common thread. Every one of these disputes was preceded by a publicly known
contract expiration date, a publicly known sticking point, and weeks or months of visible tension
before the walkout itself. The companies that rerouted cargo early, or diversified which port their
freight moved through, were reacting to information that was already public. The companies caught
flat footed usually weren’t tracking the contract calendar at all.
Prevention: Treat the Labor Calendar Like a Supply Risk
A port strike is one of the more predictable disruptions in global trade, precisely because labor
contracts have known expiration dates and negotiations happen in public. The gap isn’t information. It’s
that most companies have no process for connecting “this contract expires in four months” to “this is
the port 30 percent of our imports move through” until the walkout has already started.
How ScopeMatch Maps to Each Failure Point
Six places where knowing which vendors route through which port, ahead of time, changed the outcome.
Vendor risk ratings and dashboard rollups
Vendor and location records roll up to show exactly how much volume moves through a single port
or region, so “what happens to us if the ILA contract isn’t renewed on time” is a question with
an answer already on file.
Workflow based qualification
Qualifying an alternate port, carrier, or inland route runs through a defined pipeline, stages,
checklists, document requirements, started while a contract negotiation is still ongoing rather
than after the picket line goes up.
Document tracking with expiry alerts
Carrier agreements, customs paperwork, and routing documentation are centralized per vendor with
automated expiry alerts, so a fast reroute doesn’t also mean discovering missing paperwork at an
alternate port.
Checklist notes with document evidence
When a carrier confirms an alternate routing during a live disruption, that confirmation attaches
directly to the relevant checklist item with a note and any supporting document, rather than
living only in a phone call made during a crisis.
Incidents with resolution records
A strike-driven delay becomes a logged incident, type, severity, status, owner, rather than a
disruption reconstructed from memory when a customer asks what happened three months later.
Assignment, roles, and comments
Every vendor has a named owner, with admin, manager, reviewer, and viewer roles controlling who
can act. When a port closes overnight, comments on the affected vendor records notify the right
people immediately instead of scattering across separate calls.
The Broader Point
Port strikes are, almost uniquely among supply chain disruptions, telegraphed in advance. The contract
expires on a known date. The sticking points are public. What separates the companies that absorbed
the 2024 to 2026 wave of walkouts from the ones that got stuck wasn’t foresight into labor relations.
It was already knowing which of their own vendors, and which of their own cargo, ran through the port
in question. ScopeMatch exists to keep that answer current before the calendar forces the question.
