Amid an increasingly damaging labor dispute, 29 West Coast seaports which handle billions of dollars of goods will be mostly closed four of the next five days.
The announcement was made Wednesday by companies that employ dockworkers.
Negotiations for a new contract were to resume Wednesday, but were canceled. The two sides last met Friday.
The employers now say they won't hire crews to load or unload ships Thursday, Saturday, Sunday or Monday — when they'd have to pay holiday or weekend wages. Instead, smaller crews will focus on clearing already-unloaded containers off dockside yards.
Cargo is struggling to cross the docks amid historically bad levels of congestion. Employers blame crowded docks on longshoremen staging work slowdowns; dockworkers deny slowing down and say companies are exaggerating to cut their shifts.
