US Port Labor 2026: How the ILWU Contract and Port Automation Disputes Affect Import Lead Times

The ILWU contract runs until 2028, but automation disputes, early positioning for the next negotiation, and the ILA strike precedent are already reshaping import lead times. Procurement teams that treat port labor as a 2028 problem are making a mistake.

In June 2026, the International Longshore and Warehouse Union (ILWU) and the Pacific Maritime Association (PMA) began early discussions toward the next West Coast port labor contract. The current six-year deal does not expire until July 1, 2028. But the early talks signal something procurement teams cannot ignore: port labor on the West Coast is already a live risk factor, even though the contract deadline is two years away. [1]

The ports of Los Angeles and Long Beach handle more than 30% of all containerized imports entering the United States. [2] Another 10% moves through Oakland, Seattle, and Tacoma — all ILWU-represented. Combined, West Coast ports process roughly 40% of U.S. container imports. [3] When labor tension rises at these gateways, the entire U.S. import supply chain feels the pressure — longer lead times, higher freight costs, and inventory risk that procurement teams must account for in their planning assumptions.

This article examines the current state of ILWU labor relations, the unresolved automation disputes that fuel mistrust, the cargo volume shifts underway, and what procurement teams should do about it in 2026 and beyond.

The 2023 contract: a fragile truce, not a solution

The ILWU ratified its current six-year contract in September 2023 with 75% member approval. [4] The contract covers 22,000 workers across 29 West Coast ports. It came after 13 months of contentious negotiations, multiple local union job actions, and growing fears of a strike that would have crippled supply chains at the busiest U.S. import gateway. The agreement made the contract retroactive to July 1, 2022 and set the expiration date for July 1, 2028. [4]

The ratification was a relief for importers who had watched the 2022–2023 negotiations unfold with alarm. During the talks, ILWU Local 13 withheld workers on April 6 and April 7, 2023, effectively shutting down the ports of Los Angeles and Long Beach. [5] In March 2023, workers stopped staggering their lunch breaks, shutting the ports for an extra two hours each day and triggering significant delays. [5] These were not strikes — they were informal job actions that nonetheless produced measurable disruptions in container flow.

The lesson for procurement is uncomfortable but clear: the existence of a ratified contract does not eliminate labor risk. The 2023–2028 contract reduced the probability of a catastrophic strike, but it did not resolve the structural conflicts that drive operational slowdowns during periods of tension.

Automation: the dispute that will not go away

Automation is the central unresolved issue in West Coast port labor relations. It was the main sticking point during the 2022–2023 negotiations and remains the primary source of mistrust between the ILWU and terminal operators. [6]

The ILWU underwrote a study released in June 2022 that found automation at two San Pedro Bay terminals — Long Beach Container Terminal and TraPac at the Port of Los Angeles — eliminated the equivalent of 572 full-time ILWU jobs annually. [6] The PMA countered with its own study arguing that automation increased overall ILWU job opportunities and noted that throughput per acre was 44% higher at automated terminals compared to manual ones. [6]

Both sides can cite data to support their position. What matters for procurement is the operational consequence: the automation dispute creates an environment where any new technology deployment at a West Coast terminal becomes a flashpoint. Terminal operators who invest in automation risk provoking resistance from the union. The ILWU resists automation because it has resisted it for the last two decades, viewing it as an existential threat to jobs. [7] The result is that West Coast terminals lag global peers in automation adoption. Ports in Rotterdam, Antwerp, Singapore, and even the automated terminals being built on the U.S. East Coast are moving ahead. West Coast ports are not.

In June 2026, ILWU President Bobby Olvera Jr. spoke at the Agriculture Transportation Coalition meeting in Tacoma, Washington, and argued that recent disputes between the union and PMA have strained labor-management relations during the current contract term. He cited ongoing fights over work jurisdiction at automated terminals, where the two sides continue to disagree over which jobs should be performed by ILWU members and which can be assigned to outside workers or contractors. [8]

The automation issue also spreads beyond the West Coast. During the 2024 ILA contract negotiations on the East and Gulf Coasts, automation was similarly a central sticking point. The dispute contributed to a two-day strike across 36 ports from Texas to Maine in October 2024. [9] The ILA strike demonstrated that port labor disruption is not a West Coast-specific issue — and that the automation dispute is a nationwide structural challenge for the U.S. port system.

East Coast port strike: the precedent that reshaped assumptions

The October 2024 ILA strike was short — two days — but its implications for procurement are long-lasting. Halting operations at 36 ports from Texas to Maine demonstrated that labor disruption at U.S. ports is not hypothetical. It happened. Carriers diverted cargo. Backups accumulated. Importers who had shifted volume from the West Coast to East Coast ports as a labor hedge discovered that East Coast ports carried their own labor risk. [9]

The ILA strike also raised the stakes for the next ILWU negotiation cycle. Industry observers noted that the gains the ILWU achieved in 2023 placed added pressure on ILA negotiations. [10] That dynamic runs both ways: any gains the ILA secures in its next contract will influence ILWU expectations in 2028. The two unions do not coordinate formally, but contract terms in one coast ripple into expectations on the other.

Volume shift: cargo is already leaving the West Coast

Importers have been voting with their routing decisions for years. The West Coast share of U.S. container imports declined steadily through the 2010s and 2020s. By 2023, the LA-Long Beach port complex handled just 33% of U.S. container traffic. [11] By 2025, LA and Long Beach processed 10.1 million TEUs combined, but their market share continued to erode as Houston, Savannah, Virginia, Charleston, and New York and New Jersey absorbed a growing proportion of import flows. [11]

The 2014–2015 ILWU contract negotiations produced months of slowdowns that cost significantly more than any freight cost differential importers were managing. [11] The 2002 ILWU lockout cost the U.S. economy an estimated $1 billion per day. [11] Every importer who routed cargo through West Coast ports during those periods experienced delays that disrupted supply chains.

Importers now use a four-corner approach: splitting volume across West Coast, East Coast, Gulf Coast, and Mexican border gateways. [11] The strategy adds complexity — multiple customs bonds, multiple drayage networks, multiple warehouse networks — but it reduces the downside of any single port disruption. Many importers now maintain dual-coast warehousing as a standard contingency, not an emergency measure. [7]

Why 2026 matters despite the 2028 contract

Procurement teams that dismiss the ILWU situation as a 2028 problem are making a mistake. Three dynamics make 2026 a year when port labor risk is relevant to procurement planning.

First, early negotiations create uncertainty. The early discussions between West Coast ports and the ILWU for the next contract, while intended to pre-empt disruption, signal that both sides anticipate a challenging negotiation. [1] Early positioning means public statements, posturing, and the potential for local job actions as the 2028 deadline approaches. The 2022–2023 experience shows that informal disruptions can start well before a contract deadline.

Second, automation disputes are continuous. The fight over automation does not pause between contract cycles. Terminal operators continue to invest in technology. The ILWU continues to resist. Each new automation announcement at a West Coast terminal is a potential trigger for resistance. Procurement teams routing goods through semi-automated terminals at LA-LB, or through TraPac's automated facility, face different labor relations profiles than those routing through fully manual terminals. [8]

Third, the volume shift is creating a two-tier port system. As importers divert volume to East and Gulf Coast ports, those ports face capacity constraints that were previously concentrated on the West Coast. Savannah handled 5.7 million TEUs in 2025, up 2.6%. Houston is expanding rapidly. [11] The diversion strategy works only until the destination ports reach capacity — at which point congestion and delays shift east, not disappear.

How import lead times get disrupted

Port labor disruption affects import lead times through multiple mechanisms, and procurement teams need to understand each one to build effective contingency plans.

Berth delays. The first observable impact is vessels waiting offshore for available berths. During the 2014–2015 slowdown, vessel queues at LA-LB stretched to ten or more ships at anchor. Each day of waiting adds to total transit time from factory to warehouse. For a shipment from Shanghai to a Los Angeles distribution center, the ocean segment is typically 12–14 days. Even five extra days at anchor represents a 35–40% increase in total transit time.

Crane productivity. Work-to-rule actions reduce crane moves per hour. The ILWU does not need to strike to slow operations. When workers strictly follow every safety procedure, rotate positions more frequently, or take breaks at precisely scheduled intervals, container throughput drops by 15–25% without any formal work stoppage. [5] During the 2023 lunch break dispute, operations effectively shut for two extra hours per day — a 25% reduction in daily working time.

Container availability. When vessels are delayed and crane productivity drops, containers take longer to move from ship to terminal yard to chassis. Importers face extended dwell times, demurrage charges, and the inability to retrieve cargo on schedule. For time-sensitive goods — retail seasonal merchandise, perishables, manufacturing inputs — these delays translate directly into missed sales or production stoppages.

Rail and truck bottlenecks. Port slowdowns cascade inland. When containers stack up at marine terminals, the rail and truck networks that serve the port become congested. Railcar availability drops. Chassis pools empty. Truck turnaround times at terminal gates increase. [11] For procurement teams that rely on intermodal rail to move containers from West Coast ports to inland distribution centers in Chicago, Dallas, or Memphis, a port labor disruption creates a secondary disruption in the inland leg that can take weeks to clear after the port itself returns to normal operations.

What the data tells us about disruption frequency

The pattern of West Coast port labor disruption is not random. It follows the contract cycle. The last three ILWU contract negotiations — 2002, 2014–2015, and 2022–2023 — all produced significant operational disruption. The 2002 lockout was the most severe, with a direct economic impact estimated at $1 billion per day. [11] The 2014–2015 negotiations produced months of slowdowns that drove importers toward permanent routing changes. [7] The 2022–2023 talks generated a full year of uncertainty and multiple local job actions. [4]

This pattern is now predictable enough that importers build it into their routing and inventory strategies. The frequency of disruption may decrease with longer contract durations — the current six-year deal is the longest in recent ILWU history — but the severity of any single disruption event is not necessarily lower. A more contentious negotiation after a longer contract period could produce more severe disruption, not less.

Procurement action plan for 2026–2028

Procurement teams should treat West Coast port labor as a structural risk factor from now through at least the 2028 contract ratification. The following actions are specific, measurable, and implementable with existing resources.

1. Quantify West Coast port dependency. Measure the share of your import volume that moves through ILWU-represented ports. Break it down by SKU, by business unit, and by revenue impact. Organizations that know their exact exposure can prioritize contingency investments. Organizations that estimate are guessing.
2. Build port routing flexibility into ocean contracts. Current ocean procurement contracts should include options to reroute via alternate ports. Clarify cost-sharing for diversion when labor issues materially impair performance. Without this language, carriers have no obligation to offer alternatives at contract rates.
3. Increase safety stock for critical SKUs. For products with long lead times, low demand flexibility, or high revenue impact per unit, hold additional safety stock in west coast or inland distribution centers. Historical data shows inventory carrying costs are lower than the cost of stockouts plus emergency freight during labor disruptions.
4. Establish monitoring triggers. Define objective signals that automatically initiate diversions: average vessel wait time exceeding 5 days at LA-LB, reported ILWU job actions, or public breakdown of early contract discussions. Pre-authorized triggers remove decision delay during a disruption.
5. Align suppliers upstream. Push Asian suppliers to dispatch shipments earlier against seasonal deadlines when labor risk is elevated. The 2022-2023 experience showed that congestion builds quickly once slowdowns start. Early shipments buffer against the first weeks of reduced throughput.

The four-corner strategy: diversification with discipline

Diversifying port routing has become the standard risk management response to ILWU labor uncertainty. But the strategy has limits that procurement teams need to understand.

The Port of Savannah handled 5.7 million TEUs in 2025. [11] Houston has invested heavily in new capacity. The Port of Virginia and the Port of Charleston continue to expand. These are effective alternatives, but they are not infinite capacity reservoirs. If a significant share of West Coast volume diverts east simultaneously, the destination ports will congest. Shipping lines will face equipment repositioning challenges — containers ending up on the wrong coast for their next load. Drayage capacity in Savannah or Houston may not scale proportionally to a sudden surge in volume.

The four-corner strategy works best when it is pre-planned and gradual, not reactive and sudden. Procurement teams should identify alternative routing options for each high-volume SKU or supplier group, pre-qualify drayage carriers at alternate ports, and maintain the logistics relationships needed to execute a diversion on short notice. The time to establish a relationship with a Savannah warehouse provider is not the same week you need to divert your first container there.

Cost implications: 50–100% freight rate spikes are plausible

Severe labor actions at West Coast ports can trigger ocean freight rate increases of 50–100%. [3] When port capacity becomes constrained, the scarcity of available berth slots allows carriers to raise spot rates. Accessorial charges — demurrage, detention, chassis and storage — compound the cost increase. Importers may be forced into airfreight for critical shipments, multiplying transportation costs by 5–10x for the most time-sensitive goods.

For a procurement team managing $100 million in annual ocean freight spend, a 50% rate increase translates to $50 million in unbudgeted cost. This is the magnitude of financial exposure that makes port labor risk a board-level conversation, not a logistics-only issue. The mitigation strategies — longer contract commitments, multi-port routing, safety stock — have costs, but those costs are known and capped. The cost of an unmitigated disruption is unknown and potentially far larger.

Looking ahead: 2028 contract risks are being set now

The decisions made between 2026 and 2028 will determine whether the next ILWU contract negotiation is smooth or disruptive. ILWU President Olvera has been clear that the union's trust in terminal operators is fragile. Automation disputes are ongoing. The early discussions that began in 2026 will set the tone for what happens when the contract actually expires. [8]

Terminal operators face competitive pressure to automate. Global container throughput rose 2.1% in Q1 2026. [1] E-commerce growth continues to drive import volumes. The Panama Canal faces ongoing drought-related transit restrictions that add to the attractiveness of West Coast routing — but only if West Coast ports can offer reliable throughput. [1] The tension between efficiency demands and labor protection is structural. It will not be resolved by any single contract.

For procurement, the appropriate response is not to predict the outcome but to prepare for the range of possible outcomes. Assume that port labor will be a risk factor for at least the next two years. Build routing flexibility, inventory buffers, and contract language that protects against disruption. Monitor the signals — early negotiation progress, automation announcements, ILWU-PMA statements — and be ready to act when the indicators change.

The ILWU contract may expire in 2028, but the risk to import lead times is already present in 2026. Procurement teams that prepare now will be the ones managing stable supply chains two years from now. The teams that wait will be the ones paying spot rates and explaining delays to their stakeholders.
