Truck drivers for a transportation company serving the Los Angeles and Long Beach ports entered their 10th week protesting what they say are more than $6 million in wages and expenses stolen by their employer, a Teamsters official said Monday.

The drivers picketing at Pacific 9 Transportation’s Carson truck yard say they should be on the pay roll as employees but are instead misclassified as independent contractors.

Teamsters officials say 38 drivers who work for Pac 9 have given testimony to the California Division of Labor Standards Enforcement in the past six weeks and presented evidence showing they were cheated out of $6 million in expenses, unpaid meal and rest breaks and illegal deductions, as well as $2 million in liquidated damages, interest and waiting time penalties.

The Labor Commissioner’s Office is expected to make a decision on the drivers’ claims in the upcoming weeks.

The Pac 9 drivers haul goods for retailers such as Hewlett-Packard, Costco, Microsoft and Foot Locker.
