In State ex rel. McKnabb v. Indus. Comm. (2001), 92 Ohio St.3d 559, 561, 2001 Ohio 1285, 752 N.E.2d 254, the court held that the rule or policy supporting an employer's voluntary abandonment claim must be written. The court explained: Now at issue is Louisiana-Pacific's reference to a written rule or policy. Claimant considers a written policy to be an absolute prerequisite to precluding TTC. The commission disagrees, characterizing Louisiana-Pacific's language as merely illustrative of a TTC-preclusive firing. The commission believes that there are common-sense infractions that need not be reduced to writing in order to foreclose TTC if violation triggers termination. This argument, however, contemplates only some of the considerations. Written rules do more than just define prohibited conduct. They set forth a standard of enforcement as well. Verbal rules can be selectively enforced. Written policies help prevent arbitrary sanctions and are particularly important when dealing with employment terminations that may block eligibility for certain benefits.
