BURLINGTON CITY, N.J. (AP) — A state appellate court has upheld a southern New Jersey school teacher’s legal victory in an ongoing dispute over using a sick day during last year’s Philadelphia Eagles Super Bowl victory parade. The panel on Wednesday upheld a state Public Employment Relations Commission decision that the teacher’s union can challenge a decision to deny Robert Gurry sick leave. The judges found the “football flu” grievance can be decided by an arbitrator.
