Dockers’ strikes: a chain reaction of disruption in global trade

Dockers’ strikes have become a recurring issue in the global supply chain landscape. As key players in trade exchanges between countries, dockworkers significantly influence logistics and operational efficiency within the maritime sector and international trade. Any labor shortages extend beyond port operations and can disrupt the interconnected web of logistics that relies on the timely and efficient movement of goods. This analysis explores the ramifications and potential disruptions caused by dockers’ strikes, focusing on logistics, operational challenges, and possible solutions to mitigate these impacts.

Notable dockers strikes at major cargo ports these past years

Port congestion poses a significant challenge to global trade, and one contributing factor is docker strikes. Such situations often arise from disputes over wages, working conditions, or job security. These strikes can vary in duration and scale, affecting local, national, and even international trade. As ports serve as vital nodes in global supply chains, any interruption at these locations can have a cascading effect on various stakeholders, from manufacturers to retailers.

Several major ports worldwide have faced substantial disruptions in recent years due to prolonged docker strikes. These notable examples underscore the significant impact such actions can have on logistics operations and the broader economy. Prolonged disruptions can affect port operations and ripple across retail, automotive, and technology industries, causing significant financial losses.

US East Coast ports in 2024

A strike initiated by the International Longshoremen’s Association (ILA), representing 45,000 workers, began on October 1st. This action paralyzed operations at numerous ports along the Eastern and Gulf Coasts, from Maine to Texas, causing widespread disruption to trade in the region. A major point of contention in the labor dispute centers on the introduction of new technologies at US ports. Workers fear that these technologies could lead to job losses. The union is demanding a complete halt to the automation of cranes, gates, and container handling equipment, as well as substantial wage increases.

The effects of this first shutdown in almost 50 years forced the diversion of some cargo to West Coast ports, which were already operating at full capacity, leading to widespread congestion across the country. This strike further exposed vulnerabilities in the U.S. supply chain infrastructure, already weakened by the post-pandemic surge in demand and limited port capacities.

Port of Vancouver (Canada) in 2023

In 2023, dockworkers in the Port of Vancouver staged work stoppages for 13 days, between July 1st and 13th, over contract negotiations. With over 7,000 workers involved, the action brought Vancouver, which is British Columbia—Canada’s busiest port—to a standstill, halting an estimated $10 billion in trade. The ripple effect impacted not only Canadian industries but also global trade routes, further compounding existing supply chain challenges across North America.

Port of Los Angeles and Port of Long Beach in 2022

In 2022, dockworkers at the Port of Los Angeles and Port of Long Beach, in the United States, participated in various work stoppages and labor actions over contract negotiations with Pacific Maritime Association (PMA). The ILWU represents nearly 29,000 dockworkers at 29 ports along the West Coast that handle approximately 50% of all container traffic in the United States. The PMA represents nearly 70 terminal operators at these ports. This labor shortage, coupled with a surge in imports at these major ports on the US West Coast, exacerbated congestion issues that had already plagued the ports during the COVID-19 pandemic

Port of Felixstowe in 2022

In 2022, dockworkers at the Port of Felixstowe, the UK’s primary hub for container shipping, launched a strike over pay disputes. This 8-day action, which disrupted nearly half of the UK’s container trade, further strained the British economy, already reeling from the impacts of Brexit and the COVID-19 pandemic. The delays caused by the strike had a cascading effect on industries such as retail, manufacturing, and automotive across the United Kingdom.

Unexpected ramifications of dockers’ strikes on supply chain efficiency

Docker strikes can have far-reaching effects on supply chains, impacting logistics operations, local economies, and even overall market stability. Beyond immediate operational delays, dockers’ strikes often trigger inflationary pressures on shipping rates, cause supply shortages, and impact consumer prices, with economic consequences reaching far beyond the ports themselves.

A barrier to smooth logistics operation

One of the most immediate effects of dockers’ strikes is the delay in shipments. When dockworkers halt operations, vessels may be unable to unload cargo or load new shipments, leading to increased waiting times for ships. This disruption can create bottlenecks in the supply chain, preventing timely delivery of goods to consumers and businesses alike. For example, the delays at U.S. ports during the 2022 strikes contributed to inventory shortages, particularly affecting the retail and automotive industries, which rely on just-in-time deliveries.

Furthermore, port capacities may not be restored quickly, even after dockworkers resume their duties. Operators may struggle to manage incoming and outgoing cargo effectively, exacerbating congestion and operational inefficiencies. The backlog of cargo at ports can overwhelm terminals and warehouses. For shipping lines, upcoming shipping schedules are disrupted due to longer wait times for vessels.

For businesses, port slowdowns or shutdowns make inventory management a daunting task. Companies that rely on just-in-time (JIT) inventory systems may find themselves unable to maintain optimal stock levels, leading to potential shortages or overstock situations. For manufacturers, this can halt production lines, while retailers may face empty shelves. Perishable items are highly susceptible to damage from extended storage. This underscores the broader economic implications of these strikes, with entire industries suffering from cascading disruptions.

The broader economic and financial implications

Delays due to strikes create a backlog of cargo ships waiting to dock and delays in unloading containers, disrupting the flow of goods. This situation results in a cascade of financial consequences. Some analysts estimate that extended port strikes could reduce GDP by several percentage points, especially in countries highly dependent on international trade.

Shipping lines face increased operational costs. Each additional day a ship waits to dock incurs extra expenses for fuel, crew wages, and port fees. Idle containers at the terminal also create charges from port operators. Overcharges and limited capacity sometimes force ocean carriers to increase freight rates. Companies may need to reassess their logistics strategies to meet their delivery commitments and customer demand. This could involve rerouting shipments or shifting to alternative modes of transportation, such as air freight. These options are often more expensive and complex, potentially straining relationships with freight forwarders and logistics partners. Retailers and manufacturers are left to absorb higher costs, including shipping, demurrage, and detention fees, which are ultimately passed down to end consumers.

Beyond the immediate effects on the supply chain, dockers’ strikes often have broader economic repercussions. Many businesses rely on specific routes and ports for their imports and exports. Small and medium-sized businesses (SMBs) are particularly vulnerable to shortages, as even a few weeks of disruption can impact their payroll and jeopardize their viability.

In certain regions, local industries depend on raw materials or products from abroad, while others sell their goods to overseas customers. In the interconnected global trading system, a strike at one major port can disrupt industries in landlocked countries that lack direct access to the ocean. The interconnectedness of modern economies means that even landlocked regions far from the coast feel the economic shockwaves of dockers’ strikes, illustrating the far-reaching implications of such disruptions.

In 2022, dockworkers at the Port of Los Angeles and Port of Long Beach, in the United States, participated in various work stoppages and labor actions over contract negotiations with Pacific Maritime Association (PMA). The ILWU represents nearly 29,000 dockworkers at 29 ports along the West Coast that handle approximately 50% of all container traffic in the United States. The PMA represents nearly 70 terminal operators at these ports. This labor shortage, coupled with a surge in imports at these major ports on the US West Coast, exacerbated congestion issues that had already plagued the ports during the COVID-19 pandemic

Strategies to mitigate the impact of dockers’ strikes and build resilient supply chains

In light of the challenges posed by dockers’ strikes, businesses can adopt various strategies to enhance their supply chain resilience and minimize disruptions.

To mitigate the impact of dockers’ strikes, businesses can diversify their supply chain routes and modes of transport. By establishing relationships with multiple ports or exploring alternative transport methods, companies can reduce reliance on any single point of failure. This approach can help maintain the flow of goods even during disruptions.

Enhance inventory buffering

Businesses may consider adopting more robust inventory management strategies, including maintaining safety stock to buffer against potential disruptions. This approach can help absorb the shock of delays, allowing companies to meet customer demands despite temporary setbacks in supply chains. Notably, larger firms have been adopting this strategy to anticipate unforeseen disruptions, helping them remain competitive despite global supply chain challenges.

Invest in technology

Leveraging technology can enhance supply chain visibility and communication. Implementing real-time tracking systems and analytic tools can provide businesses with up-to-date information on shipment statuses and potential disruptions. A wide range of specialized tools is now available to businesses across various sectors to enhance supply chain management. These tools leverage artificial intelligence, machine learning, the Internet of Things (IoT), and real-time data processing software. This improved visibility enables more informed decision-making and helps companies respond effectively to changing conditions.

Foster collaboration

Strengthening collaboration among supply chain partners can enhance resilience. Companies can engage in joint planning efforts with suppliers, logistics providers, and even competitors to develop contingency plans and share resources during disruptions. Collaborative initiatives can foster a more resilient supply chain ecosystem.

Address labor relations

Engaging in proactive negotiation with labor unions can help mitigate the frequency and severity of strikes. Companies can work towards understanding and addressing the root causes of dockers’ grievances, such as wage disparities, job security concerns, or unsafe working conditions. Building positive labor relations can minimize the risk of strikes and work stoppages.

Conclusion

The global economy’s increasing reliance on international trade, compounded by the rise of e-commerce, has heightened the stakes of supply chain disruptions caused by dockers’ strikes. As seen in recent years, even short-term strikes can lead to significant economic ramifications. However, by adopting robust supply chain management strategies, businesses can mitigate these disruptions and maintain resilience in the face of global uncertainty.
