misterOne of the largest national car wash chains in the country is in hot water after allegation of racial discrimination surfaced recently. Mister Car Wash has been accused in a lawsuit filed by the U.S. Equal Employment Opportunity Commission of passing over black workers for management positions and promotions. The news came on Thursday, the same week the car wash chain announced its expansion into the state of California.

Fox News reports that the lawsuit claims both Mister Car Wash and Mister Hot Shine Carwash engaged in practices of promoting less-qualified white workers over their black colleagues when it came to awarding senior positions. The lawsuit also claims that the chain would even train those white employees it promoted once they were in the higher position.

The lawsuit was filed in the U.S. District Court in Northern Alabama. Mister Car Wash is headquartered in Arizona and employs more than 2,000 people across more than 200 locations in 20 states. Executives with the chain told Fox News that the allegations in the lawsuit have no merit.

AL.com shared the statement from the chain which read: “Mister Car Wash does not make employment decisions based on race. We believe the claims made in the EEOC lawsuit are without merit and we will vigorously defend ourselves in court.”
