Container terminals at the Port of New York and New Jersey were idled Friday morning when International Longshoremen’s Association workers walked off the job. The walkout began about 10 a.m., and reportedly affected all port terminals. Trucking company dispatchers advised drivers to avoid joining queues outside terminal gates. There was no official confirmation of the cause of the walkout. However, multiple sources said it was due to ILA unhappiness with hiring rules of the Waterfront Commission of New York Harbor (WCNYH), which oversees port hiring.
