This case is significant for two reasons. First, it continues the Ohio Supreme Court's trend towards the reinvigoration of employment at-will, which started in Wiles v. Medina Auto Parts (as an interesting side note, the same lawyer was on the losing side of both Wiles and Leininger). Given the decision in Wiles, though, Leininger's result is not a surprise.
Perhaps more significant is the underlying effect of this decision on the statute of limitations for age discrimination claims. Common law wrongful discharge claims have a four-year statute of limitations. Because state age discrimination claims are now limited to the statute, such claims will be controlled by the statute's 180-day statute of limitations for age claims (unless the employee elects to pursue the lesser remedies of reinstatement/back pay and attorneys' fees available under R.C. 4112.14 and its six-year statute of limitations). It is safe to assume that this case will also do away with public policy claims for all other forms of discrimination, although that effect will most likely not be felt, since R.C. 4112.99 has a six-year statute of limitations for all types of discrimination other than age. As a result of Leininger, and at least as far as state age claims are concerned, employers will have a greater degree of certainty regarding adverse employment decisions after six months (as opposed to four years) have elapsed.
