No. Kentucky courts have ruled that an employee fired because he or she refuses to commit perjury in a legal proceeding may pursue a claim for wrongful discharge to recover their damages as well as punitive damages. Hill v Kentucky Lottery Corp, 327 SW3d 412 (Ky 2010) and Northeast Health Mgmt., Inc. v. Cotton, 56 S.W.3d 440, 449 (Ky App. 2001). The Sixth Circuit recently upheld a jury's verdict in a fired employee's favor where the jury found that the employee was fired for refusing to commit perjury in regard to a sex discrimination case against the employer. Burton v. Zwicker & Associates, No 13-5406 (August 22, 2014).
The Burton decision is discussed further on Robert Abell's Kentucky Employment Law Blog: An Employer Cannot Fire An Employee Because the Employee Refuses to Commit Perjury.
