CHICAGO - The Seventh Circuit U.S. Court of Appeals on Oct. 26 affirmed a federal district court's decision granting summary judgment in favor of the postmaster general of the U.S. Postal Service, finding that an employee failed to prove that he was retaliated and discriminated against in relation to his claims that exposure to mold at work made him sick (John D. Anderson v. Patrick R. Donahoe, Postmaster General of the United States Postal Service, Great Lake Operations, No. 11-3784, 7th Cir.; 2012 U.S. App. LEXIS 22218).
