Supervisor Altered Sign-in Times

How accurate is accurate? The Federal Circuit Court of Appeals recently upheld the discipline of a Postal Service supervisor who had falsified at least 17 time records to show that employees had returned to the office before the 5:00 P.M. (Davis v. United States Postal Service, C.A.F.C. No. 2007-3255, 12/10/07). The supervisor had claimed that he had only been entering correct return times for employees who had returned on time but failed to clock in as they should have. Thanks to Fedsmith for the link.
