The Port Authority of New York and New Jersey is "coordinating with partners across the supply chain to prepare for any impacts" from a possible work stoppage by workers represented by the International Longshoremen's Association as they negotiate with the United States Maritime Alliance (USMX), a Port Authority spokesperson told CBS MoneyWatch on Friday. "We urge both sides to find common ground and keep the cargo flowing for the good of the national economy," added the spokesperson, noting that $240 billion in goods move through the two ports each year and that such trade supports more than 600,000 local jobs. According to the union, a strike would affect ports from Maine to Texas. A stoppage could involve up to 45,000 workers at ports that account for roughly 60% of U.S. shipping traffic, leading to a major disruption of shipments, Oxford Economics said in a report.
