Dockworker Union Threatens to Close Shipping Ports Handling 60 Percent of Traffic

Dockworkers say they’ll strike on Sept. 30 if no new contract is in place, potentially halting activity at ports from Maine to Texas that collectively handle more than 60% of total U.S. container volume. The International Longshoremen’s Association suspended negotiations in June over a technical dispute, and no new talks have been scheduled.
