Seven Denver area warehouse workers were reportedly awarded nearly $15 million in a discrimination lawsuit filed in 2010, after a federal jury found that they were being segregated because of their race and constantly being racially insulted by their White bosses and colleagues.

The jury found that the managers and supervisors at Matheson Trucking and Matheson Flight Extenders forced Blacks to work on one side of the Commerce City warehouse while Whites worked on the other side, according to CBS Denver. The Sacramento, Calif.-based company transports mail for the U.S. Postal Service and private vendors, including UPS and the Federal Express.

White supervisors and staff were accused of calling employees racial slurs, even going as far as calling them “lazy, stupid Africans,” and using the N-word to refer to Black workers.

The plaintiffs in the lawsuits were Ernie Duke, Mahamet Camara, Andre De Oliveira, Bemba Diallo, Salif Diallo, Macire Diarra, and Dean Patricelli. The workers were reported to be immigrants from the African nation of Mali and Brazil, and one White whistleblower from the United States.

The White plaintiff, Dean Patricelli, was fired when he spoke out against the racist practices of the supervisors. Patricelli said he was ostracized by his bosses and peers when he spoke out against the racial segregation and was labeled as the “tribe’s assistant,” according to the Denver Post.

“Basically, I did the right thing,” he told the Denver Post. “This isn’t 1960 anymore.”

The Post also reported that the plaintiffs were able to retrieve internal company memos that proved supervisors were “using a downsizing to target Black employees for firing, including Duke who had been working at the company for nine years and was second in seniority.”

The workers also claimed that their working conditions grew worse in 2007, when Leslie Capra took charge as the station manager. Capra was reported to be more hostile and crude towards the Black employees, and she encouraged supervisors to convey the same attitude.

The lawsuit stated that “under Ms. Capra’s management, Black employees were discriminated against with respect to almost every aspect of their employment.”

The verdict included a $14 million monetary reward in punitive damages, $318,000 in back pay for workers who were fired for being Black, in addition to $650,000 for emotional distress.
