delivered the opinion of the court:
Plaintiff appeals from the December 9, 1985, order of the circuit court which denied rehearing of the order which dismissed her two-count complaint with prejudice. She contends that the decision of the Illinois Department of Labor hearings referee, adopted by the Illinois Department of Labor Board of Review, denying her unemployment compensation benefits because she was discharged for misconduct connected with her work, did not preclude an action in the cirсuit court based on retaliatory discharge.
We affirm.
Pertinent to our disposition are the following facts. Plaintiff was employed by defendant from September 4, 1976, to August 30, 1983, at which time she was fired. On August 17, 1982, the plaintiff filed an application for adjustment of claim with the State of Illinois Industrial Commission for the injuries she sustained while working on April 6, 1982. The applicаtion was still pending before the Industrial Commission on the date defendant terminated the plaintiff’s employment. Plaintiff alleges that on June 15, 1983, she was told by an agent of defendant that her work would be closely scrutinized as a result of the filing of the application. On August 30, 1983, plaintiff was late to work and was subsequently fired.
Shortly after her discharge plaintiff applied for and received unemployment compensation benefits. Defendant appealed that grant of unemployment benefits beforе a hearings referee of the Illinois Department of Labor. The hearings referee, after hearing the evidence presented, ruled against plaintiff, concluding that:
“The claimant’s continued tardiness after so many warnings indicates a conscious disregard of the employer’s best interests. She was discharged for misconduct connected with work.”
Pursuant to statute, plaintiff appealed to the Board of Review of the Department of Labor. In its decision the Board of Review аdopted the findings of fact and decision of the hearings referee and disqualified plaintiff from receiving unemployment benefits. Plaintiff did not appeal the deсision of the Board of Review.
Plaintiff then filed the instant action in the circuit court of Cook County alleging that defendant wrongfully discharged her for exercising her rights and remedies under the Illinois Workers’ Compensation Act. (Ill. Rev. Stat. 1985, ch. 48, par. 138.4.) Defendant moved to dismiss pursuant to section 2 — 619 of the Illinois Code of Civil Procedure (Ill. Rev. Stat. 1985, ch. 110, pаr. 2 — 619(a)(4)) alleging that an essential element of plaintiff’s claim, the cause of her discharge, had been adjudicated in a prior proceeding between the parties. On September 3, 1985, defendant’s motion was granted. On September 27, 1985, plaintiff filed a motion for rehearing. On December 9, 1985, that motion was denied.
Opinion
The doctrine of res judicata bars a second adjudication where there is a former adjudication on the merits by a court of competent jurisdiction. (Yan v. Beeghly (1982),
Plaintiff contends that the Illinois Department of Labor’s (Department’s) finding is not binding upon her subsequent retaliatory discharge action because the claims do not constitute the same cause of action. We do not agree. To prevail in an action for retaliatory discharge an employee must show that he was discharged in violation of clearly mandated public policy. Gonzalez v. Prestress Engineering Corp. (1986),
Plaintiff was terminated because of excessive tardiness. The termination of her employment was therefore not in violation of clearly mandated public policy. Furthermore, the identical issue of why plaintiff was fired was presеnted in both proceedings. The Department found that the firing of plaintiff was not wrongful. Plaintiff is precluded pursuant to the doctrine of res judicata from now alleging that hеr discharge was wrongful.
However, plaintiff also contends that the doctrine of res judicata is inapplicable because the issue of whether her terminatiоn was a result of her rights under the Workers’ Compensation Act was never raised before the Department. This contention misapprehends the applicatiоn of the doctrine of res judicata. When properly invoked the judgment in the former suit is conclusive not only as to all questions actually decided, but also as to all questions which could have been litigated in the action. Neuberg v. Michael Reese Hospital & Medical Center (1983),
In the proceedings before the Department plaintiff allеged that she was wrongfully discharged. The record does not reveal her specific aUegations in support of her claim. Nevertheless, the Department fоund that plaintiff was discharged as a result of continued tardiness. In the instant case, plaintiff again alleges that she was wrongfully discharged, specifying that her discharge wаs the result of her filing her claim with the Department. The circuit court correctly ruled that the finding that plaintiff was not wrongfully discharged has a preclusive effect upоn this litigation. Res judicata is designed to enhance judicial economy by prohibiting repetitive litigation and to protect litigants from the burden of repetitive litigatiоn. Spiller v. Continental Tube Co. (1983),
Plaintiff had an opportunity to raise her claim of retaliatory discharge before the hearings referee to show that defendаnt’s charge of excessive tardiness was pretextual. Having failed to raise in the Department of Labor her contention that she was fired for filing a workers’ cоmpensation claim, plaintiff is precluded by res judicata from raising it now.
In addition plaintiff contends that if she is barred from, bringing a cause of action for retaliatory discharge, she has a civil tort cause of action against the defendant for interfering with, restraining or coercing her in the exercise of her rights under the Workers’ Compensation Act. In support of this contention, plaintiff cites Kelsay v. Motorola, Inc. (1978),
In so holding the court cited Robertson v. Travelers Insurance Co. (1983),
“To permit such a course would invite the indefinite prolonging of litigation and risk double recoveries and inconsistent findings of fact, a result which the legislature, in enacting a system of compensation in place of common law remedies certainly wished to avoid.”
Similarly, we find there to be no independent cause of action upon which plaintiff can base her recovery. Her remedy was exclusively within the Workers’ Compensation Act.
For the foregoing reasons the judgment of the circuit court of Cook County is affirmed.
Affirmed.
