iStock; Rebecca Zisser/BIThe International Longshoreman's Association will strike on October 1 if its wage demands aren't met.The strike would impact the import and export of goods across most industries, from retail to cars.Just a two-week strike could disrupt supply chains until 2025, one expert said.A major maritime workers strike is looming, and it could mean a shutdown of key goods — from cars to food — across the East and Gulf Coasts.The International Longshoreman's Association, the largest union of maritime workers in the US, announced last week that it was prepared to strike on October 1 if demands in their union contract, primarily higher wages, are not met."A sleeping giant is ready to roar on Tuesday, October 1, 2024, if a new Master Contract Agreement is not in place," ILA President Harold Daggett said in a statement.According to an ILA press release, the union wrote in a letter to its membership that its workers, who primarily work on shipping docks to load, unload, and inspect cargo and operate heavy machinery, are "struggling to pay their mortgages and rent, car payments, groceries, utility bills, taxes, and in some cases, their children's education," emphasizing the need for boosted pay in its upcoming contract.A strike would have widespread implications across the US, with significant shipment delays that could set off a chain reaction of disruptions."A prolonged strike could lead to weeks, or possibly months, of shipping delays and backlogs, worsened by limited rerouting options, high costs and time constraints," Abe Eshkenazi, CEO of the Association for Supply Chain Management, told BI.
