Three Southern California port truck drivers filed a class action lawsuit Monday against a prominent logistics company accusing their management of routinely denying workers owed wages and flouting state labor laws.

The lawsuit, filed in Los Angeles Superior Court, represents about 160 workers at XPO Logistitics Cartage LLC with offices in Commerce and San Diego. It’s the latest effort to push back on a common industry practice of contracting with big rig drivers instead of hiring them as employees, which allows companies to forgo payroll taxes and other worker protections.

Despite working five days a week, sometimes 14 hours a day, “it’s not uncommon for these drivers to take home $100 a week,” said Julie Gutman Dickinson, a lawyer representing drivers in the lawsuit filed Monday. Worse, she said workers are at times left in debt at the end of the pay period, “keeping them in indentured servitude.”

A spokesperson for the company said it had yet to receive the lawsuit.

The lawsuit alleges the company, a subsidiary of Connecticut-based XPO Logistics, routinely denied workers hourly wages even though the company treated the drivers like regular employees. Under the independent contractor model, employees are paid by the load, but must pay operational expenses including the use of tablet computers necessary to provide information about the hauls.

The fast-growing company, valued by investors at $11.89 billion, has been criticized by the Teamsters union. Last year union drivers staged a protest outside of an annual shipping conference in Long Beach, where the company’s CEO Bradley Jacobs suggested their jobs will soon be replaced by computers.

The once union-dominated trucking industry was deregulated in the 1980s, and since then short-haul trucking near Southern California ports has become dominated by companies that use independent contractors. Los Angeles and Long Beach city councils have been grappling with how to address persistent complaints from truckers.

In recent years, the California Labor Commissioner has received hundreds of complaints regarding the misclassification of port truckers and has awarded more than $35 million in back wages and penalties.

The lawsuit asks for damages, compensation for back wages and requests that the company end the practice.
