Longshoremen remain on strike at ports in New Jersey and New York despite a judge ordering them back to work.
New York Shipping Association spokeswoman Beverly Fedorko says the work stoppage entered its second day Tuesday.
Twelve ships waited to be unloaded in New York and New Jersey on Monday. Fedorko says passenger ship terminals on New York's west side were not affected.
The association says the action by International Longshoremen's Association members is related to a protest over the move of some work done by ILA workers in Camden, N.J., to a non-ILA facility in Gloucester.
Florida-based Fresh DelMonte Produce said it decided to move operations because it needed more space.
Longshoremen said the company was trying to undercut the union. International Longshoremen Association members in Philadelphia on Labor Day tossed pineapples into the Delaware River in protest.
