Significant cases dealing with defamation of character in the context of employment and labor include Bahr v. Boise Cascade Corporation and O'Donnell v. City of Buffalo, according to the William Mitchell Journal of Law and Practice. Both of these cases took place in Minnesota.
Bahr v. Boise Cascade Corporation dealt with the balance between defamation and an appropriate investigation of harassment and other inappropriate behavior in the workplace. The decision by the Minnesota Supreme Court confirmed that companies following a strict investigation plan with ample privacy protections for employees generally cannot be held liable for defamation, according to the William Mitchell Journal of Law and Practice. In O'Donnell v. City of Buffalo, a Minnesota appellate court applied the Minnesota Supreme Court's ruling to the context of harassment charges against public officials.
