Truckers who haul cargo in and out of the massive seaports in Los Angeles and Long Beach are again demonstrating against what they call unfair labor practices.
On Thursday, dozens of demonstrators set up outside eight of the twin ports' 15 container terminals.
Spokesmen for the ports reported minimal impact on port operations.
The action comes amid broader discord on the docks. The union representing longshoremen and the association representing their employers are trading blame over the slow movement of goods, even as they negotiate a contract to cover all 29 West Coast ports. Those ports handled nearly $900 billion in trade each year.
Truckers have periodically targeted several companies they say improperly classify them as contractors, not full-time employees, to minimize wages and benefits
