The California Labor Commission slammed 35 Southern California car wash businesses for failing to pay adequate wages to more than 400 employees. The commissioner’s office cited the businesses $1.3 million, according to a report from WorkersCompensation.com.

The car washes were violating minimum wage laws and failing to pay workers overtime. Seventeen car wash businesses did not carry workers’ compensation insurance as required by law.

“These citations serve as a reminder that wage theft will not be tolerated. The Labor Commissioner’s office targets its enforcement efforts on employers who intentionally skirt the law,” said Christine Baker, Director of the Department of Industrial Relations (DIR), which oversees the Labor Commissioner’s Office.
