The issues certified to this court are “whether R.C. 4113.52 is the exclusive remedy for whistleblowers and whether R.C. 4113.52 preempts the formation of a Greeley v. Miami Valley Maintenance [Contrs., Inc.] (1990), 49 Ohio St.3d 228, 551 N.E.2d 981, public-policy exception to the employment-at-will doctrine within the specific context of whistleblowing.”
We are unable to reach the certified questions in this case for the simple reason that those questions were improperly certified. We say this because Haynes is a member of a union and not an employee at will. Thus, she cannot bring a Greeley cause of action. See Greeley, supra, paragraph two of the syllabus. The fact that she cannot bring a Greeley cause of action, of course, makes moot the question of whether R.C. 4113.52 provides the exclusive remedy for whistleblowers.
In Greeley, an employer allegedly had fired an at-will employee solely because of a court-ordered child support wage assignment of the employee’s wages. Pursuant to R.C. 3113.213(D), which prohibits an employer from using an order to withhold personal earnings as a basis for discharging an employee, the employee sued the employer for his wrongful discharge. Stressing that R.C. 3113.213(D) merely imposes a modest fine against an employer who violates the statute and fails to provide a remedy for the aggrieved employee, this court held that the employee stated a cause of action in tort for wrongful discharge. Id., 49 Ohio St.3d. at 233, 235, 551 N.E.2d at 986, 987. We reasoned that the absence of *258a civil remedy for violations of R.C. 3113.213(D) would frustrate the policy and purposes of child support enforcement and that it was “our job to enforce, not frustrate, that policy.” Id. at 233-234, 551 N.E.2d at 986. Within this context, we held that “[p]ublic policy warrants an exception to the employment-at-will doctrine when an employee is discharged or disciplined for a reason which is prohibited by statute.” Id., paragraph one of the syllabus.
Greeley provides an exception to the employment-at-will doctrine. Thus, as stated above, in order for an employee to bring a cause of action pursuant to Greeley, supra, that employee must have been an employee at will. The identifying characteristic of an employment-at-will relationship is that either the employer or the employee may terminate the employment relationship for any reason which is not contrary to law. Mers v. Dispatch Printing Co. (1985), 19 Ohio St.3d 100, 19 OBR 261, 483 N.E.2d 150; Boggs v. Avon Products, Inc. (1990), 56 Ohio App.3d 67, 564 N.E.2d 1128. Haynes clearly does not qualify as an employee at will. As a member of a union, the terms of her employment relationship were governed by a collective bargaining agreement. That agreement specifically limited the power of the zoo to terminate Haynes and, as a result, took her outside the context of employment at will. Because she was not an employee at will, she is outside the class of employees for whom Greeley provides protection.
For the foregoing reasons, we reverse the judgment of the court of appeals with respect to the Greeley claim and enter judgment in favor of the zoo with respect to that claim.
Cause dismissed.
