The lawsuit says minority workers at the Capital Grille do not have the same opportunities as white employees. Reuters reported Monday that the lawsuit claims white employees are given the better-paying front-of-the-house jobs such as serving and bartending positions, while minority employees are relegated to invisible jobs such as washing dishes and preparing food.

The lawsuit also claims workers at the Capital Grille are forced to work without pay, do not get rest breaks, and have to share their tips with other employees, Reuters reported.

The suit was filed on behalf of Capital Grille employees in Chicago, as well as in New York and in Washington, D.C., Reuters reported.

Capital Grille’s Chicago location is at 633 N. St. Clair St. in the Streeterville neighborhood. There are also suburban locations in Rosemont and Lombard.
