The Pacific Maritime Association (PMA) has accused a dockers union of unlawfully disrupting operations at the ports of Los Angeles and Long Beach.

The PMA, which represents 70 ocean carriers and terminal operators at 29 west coast ports in the US, made the accusations against International Longshore and Warehouse Union (ILWU) Local 13 a week after dockworkers at both ports did not show up for work on 6 and 7 April.
