A Georgia auto repair shop that went viral last year for allegedly giving a former employee his final paycheck in thousands of oil-covered pennies, requiring nearly seven hours of cleaning, is now being sued by the Department of Labor.

A OK Walker Autoworks and its owner, Miles Walker, in Peachtree City are accused of unlawfully retaliating against Andreas Flaten with the greasy penny payment and of publishing defamatory comments about him online after Flaten contacted the department early last year about not receiving his final paycheck.

The business, located southwest of Atlanta, is further accused in the lawsuit filed Dec. 30 of failing to pay its employees overtime since at least April 5, 2019, and of failing to keep adequate and accurate records of employees pay rates and work hours, as required by law.

Flaten, in an email to HuffPost on Tuesday, described himself as pleasantly surprised by the Labor Departments filing.
