Dockworkers walked off their jobs Tuesday morning at several marine terminals at the ports of Los Angeles and Long Beach, disrupting the movement of cargo for two hours before they were ordered back.
Workers with the International Longshore and Warehouse Union are negotiating a new contract with their employers at 29 West Coast ports, but their action was unrelated to those talks.
Instead, dockworkers left their posts at three of the twin ports' 14 terminals in solidarity with truck drivers involved in a separate dispute. A spokeswoman for the drivers said they began picketing the terminals after trucks from three companies they have been trying to unionize went there to load or drop off containers.
Within two hours, an arbitrator had ordered the dockworkers to resume loading and unloading ships.
