Maria Cardenas, a Latina woman, worked for Aramark as a housekeeper at McCormick Place convention center for over 20 years. It was a long-standing rule for employees that they could not remove any items from a trade show for personal use, even if an exhibitor gave them away. Employees found in violation of this rule would be immediately fired. In October 2004, Cardenas and a co-worker, Juanita Williams, were stopped by a security guard who noticed them carrying food items away from a convention that had just ended. Both employees were discharged, but Williams was later reinstated because she was a newer employee and allegedly had been told by Cardenas that it was okay to take the items in question. Cardenas filed a national origin discrimination suit against Aramark. What does Cardenas need to show to prove that her termination was in violation of Title VII, and how might Aramark defend its decision if she states a prima facie case?[Cardenas v. Aramark, 101 FEP Cases 1114 (N.D. Ill. 2007).]
