About 2,500 former and current Dollar General store managers filed a joint lawsuit in the U.S. District Court for the Northern District of Alabama this week, the law firm representing the plaintiffs said.

The suit alleges that Dollar General intentionally misclassified the managers as “executives” in order to avoid paying the store managers overtime pay, a violation of the Fair Labor Standards Act, said Beasley, Allen Crow Methvin Portis & Miles of Montgomery, Ala.

A second lawsuit was filed in the same federal court by a single plaintiff who set out the same claims. That suit asks for certification as a “collective action” for everyone pursuing overtime pay for Dollar General store managers.

Beasley Allen, which also represents the single plaintiff, said that the federal court system has established a single multi-district litigation court to handle all these Fair Labor Standards Act claims against Dollar General.

Dollar General could not be reached for comment.
