Eugene Kilpatrick, who worked for Tyson Foods for 27 years, was terminated at age 68 and replaced by a much younger employee. His only evidence of age discrimination is an email from the manager stating that he understood how long Kilpatrick had worked for Tyson, but that Kilpatrick was not effectively doing his job. Is this enough to establish age discrimination? [Kilpatrick v. Tyson Foods, Inc., 268 Fed. Appx. 860 (11th Cir. 2008).]
