The plaintiffs are several of the thousands of employees laid off by MCI, Inc. (“MCI”), from 2001 through 2004 pursuant to reductions in force (“RIF’s”). They *251 allege that they were chosen for the RIF’s because of their age, in violation of the Age Discrimination in Employment Act of 1967, 29 U.S.C. § 623, and that MCI retaliated by failing to re-hire them after they had filed age discrimination claims with the Equal Employment Opportunity Commission. The district court entered summary judgment for MCI.

The district court carefully explained its ruling in an impressive opinion of more than one hundred pages. The court examined each plaintiffs claim and analyzed why he or she is not entitled to relief. We have reviewed the briefs and applicable law and pertinent portions of the record and have heard the arguments of counsel. The judgment is AFFIRMED, essentially for the reasons given by the district court.
