Teamster President Jim Hoffa joined striking port truck drivers Tuesday in Long Beach, saying the misclassification of these workers must end.

“You have the support of the 1.4 million Teamster members,” Hoffa said. “We will bring justice to port truck drivers and warehouse workers nationwide.”

The truck drivers who ferry goods to the ports of Los Angeles and Long Beach walked off the job Monday, but port officials said Monday the labor action had minimal impact on cargo operations.

The “unfair labor practice” strike includes drivers “misclassified as independent contractors” rather than employees by Pacific 9 Transportation and XPO Logistic, said Barb Maynard of the International Brotherhood of Teamsters. Truckers have announced several job actions and strikes over the last two years.

Representatives from area trucking companies have said that most truck drivers want to remain independent for the flexibility and the ability to own their own small businesses.

Shipping terminals remained open despite the strike, port officials said.

Port of Long Beach spokesman Art Wong said about 1,000 different trucking firms serve the port’s terminals.
