trict Court, Oklahoma, against Kmart on December 29, 1992, alleging age discrimination in violation of federal law, wrongful discharge, and intentional infliction of emotional distress. It is undisputed that prior to filing suit, employees had not filed charges of age discrimination with the Oklahoma Human Rights Commission or the Equal Employment Opportunity Commission (“EEOC”). Based on diversity jurisdiction, Kmart removed the action to federal district court. After an answer, a motion for summary judgment, and a response were filed, the parties consented to proceed before a magistrate judge.
The magistrate judge entered summary judgment in favor of Kmart as to all causes of action. The court concluded Employees’ entire suit is time barred unless the doctrine of equitable tolling is applied.
DISCUSSION
We review the entry of summary judgment de novo, drawing all reasonable inferences in favor of the nonmovants.
Applied Genetics Int’l, Inc. v. First Affiliated Sec., Inc., 912 F.2d 1238, 1241 (10th Cir.1990). Summary judgment is appropriate only when the moving party shows there is no “genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Ped.R.Civ.P. 56(c). To avoid summary judgment, the nonmovant must make a showing sufficient to establish an inference of the existence of each element essential to the ease.
Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 2552, 91 L.Ed.2d 265 (1986). The nonmovant “may not rest upon mere allegation or denials of his pleadings, but must set forth specific facts showing that there is a genuine issue for trial.”
Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 256, 106 S.Ct. 2505, 2514, 91 L.Ed.2d 202 (1986).
Employees argue their cause of action did not accrue until the time they suspected their demotions and transfers were motivated by age discrimination. They assert they did not know this until they watched the television program, “A Current Affair,” in December of 1992.
A cause of action accrues under the Age Discrimination in Employment Act (“ADEA”) “on the date the employee is notified of an adverse employment decision.” Gray v. Phillips Petroleum Co., 858 F.2d 610, 613 (10th Cir.1988) (citing Delaware State College v. Ricks, 449 U.S. 250, 256-59, 101 S.Ct. 498, 503-04, 66 L.Ed.2d 431 (1980)). “Generally, an employee is notified of an adverse employment decision when a particular event or decision is announced by the employer.” Gray, 858 F.2d at 614.
It is undisputed that the allegedly discriminatory actions by Kmart against Employees were the demotions and transfers. As such, Employees’ cause of action accrued on the dates Kmart notified them of their new assignments, i.e., February 9, 1990, and February 1, 1989.
In the alternative, Employees argue the statute of limitations under the ADEA should be equitably tolled in this case because they were constructively discharged. We are not persuaded.
It is well settled that “equitable tolling of the ADEA ... is appropriate only where the circumstances of the case ‘rise to the level of active deception’ ... “where a plaintiff has been “lulled into inaction by her past employer, state or federal agencies, or the courts.” ’ ” Gray, 858 F.2d at 615 (quoting Cottrell v. Newspaper Agency Corp., 590 F.2d 836, 838-89 (10th Cir.1979), and Martinez v. Orr, 738 F.2d 1107, 1110 (10th Cir.1984)). When such deception is alleged on the part of an employer, “[t]he limitations period will not be tolled unless an employee’s failure to timely file results from either a ‘deliberate design by the employer or actions that the employer should unmistakably have understood would cause the employee to delay filing his charge.’ ” Olson v. Mobil Oil Corp., 904 F.2d 198, 201 (4th Cir.1990) (quoting Price v. Litton Business Sys., Inc., 694 F.2d 963, 965 (4th Cir.1982)).
We are not convinced that a constructive discharge, even if shown, is sufficient to invoke the doctrine of equitable tolling. The essence of a constructive discharge claim is the employee is subjected to such intolerable
