*396 Opinion
In what is fundamentally an action for damages for wrongful constructive termination of employment, plaintiff appeals from summary judgment in favor of defendants.
Factual and Procedural Background
Plaintiff’s second amended complaint (complaint) contained causes of action for age discrimination (Gov. Code, § 12940 et seq.), sex discrimination (ibid.), wrongful constructive termination in breach of employment contract, wrongful constructive termination in breach of implied covenant of good faith and fair dealing, intentional infliction of emotional distress, negligent infliction of emotional distress, intentional interference with contractual relations, libel, slander, negligence, prima facie tort, and conspiracy.
After answering the complaint defendants 1 moved for summary judgment or, in the alternative, summary adjudication of issues. In support of the motion defendants presented plaintiff’s deposition. The following statement of facts is based on plaintiff’s deposition testimony and the parties’ joint statement of undisputed facts.
In 1966 plaintiff was hired by Lockheed Corporation as an electronic data processing typist. When plaintiff was hired she signed a document wherein she acknowledged that “no representation of employment conditions . . . shall be valid.” Plaintiff was employed by Lockheed from 1966 to 1986. During the last 10 years of that period plaintiff worked in the payroll department; she never held a managerial position at Lockheed. In 1986 plaintiff applied for a position with defendant Cadam, Inc., a subsidiary of Lockheed. Plaintiff was required to fill out a new employment application at Cadam. She was hired by Cadam to work in its payroll department. Upon accepting employment with Cadam, plaintiff again signed a document stating that “no representation of employment conditions. . . shall be valid.” In 1987 plaintiff was promoted to payroll manager; in that position she supervised one full-time employee.
Early in 1989 Cadam acquired defendant P-Cad Systems, Inc. As a result of the acquisition plaintiff’s supervisor left and was replaced by defendant Ronald Egy. In April 1989 plaintiff was promoted to manager of employee *397 services and reported directly to Egy who, in turn, reported to defendant James Pardee. As manager of employee services plaintiff supervised five employees and was responsible for various service functions as well as payroll activities. In June and August 1989 Pardee distributed memoranda setting out the goals for each manager and stating what each had accomplished. Egy met with plaintiff and advised her that she needed to spend more time training the fiill-time employees under her supervision.
On August 23, 1989, Egy prepared a written evaluation of plaintiff’s job performance. Egy divided the evaluation into two time periods: before and after plaintiff’s promotion to manager of employee services. For the period prior to her promotion Egy rated plaintiff’s performance as good; for the period following her promotion he rated her performance as “needs improvement,” but did not rate any specific job skill as unsatisfactory. Plaintiff’s overall performance was rated as good. Plaintiff and Egy discussed the performance evaluation item by item. Plaintiff disagreed with the evaluation and in September 1989 she informed Egy in writing that she felt unduly criticized. Plaintiff testified that she did not object to constructive criticism, but thought Egy should have told her about perceived shortcomings in her job performance at the time they occurred so that she could have corrected them. In plaintiff’s view it was unfair to withhold criticisms until the time of the written evaluation of her performance, which became part of her permanent record. Plaintiff further testified that she did not object to the performance rating in the evaluation, but only to the wording of the evaluation.
In a memorandum to plaintiff dated November 14, 1989, Egy informed plaintiff of her immediate reassignment (demotion) from the position of employee services manager to member of the financial staff; the memorandum explained that the reassignment would not affect plaintiff’s salary or her bonus for 1989. Plaintiff received the memorandum on November 15. She reported for work for the last time on November 17, 1989; she stayed for only half an hour and then went home because she was too upset to work. Plaintiff never returned to Cadam. On November 22, 1989, she consulted a psychologist who placed her on sick leave based on his diagnosis that she was under severe emotional distress and needed some time away from work. On January 17, 1990, while plaintiff was still on sick leave, her attorney notified defendants that plaintiff’s employment “was terminated” (i.e., plaintiff resigned) effective February 5, 1990, and that she regarded her termination as a constructive discharge by defendants. By letter dated January 30, 1990, defendants informed plaintiff that she was “absolutely welcome” to return to her job. On June 6, 1990, defendants, through counsel, offered to meet with plaintiff to alleviate any concern she might have about returning to her job. Plaintiff rejected defendants’ offers of reinstatement and commenced the present action in February 1990.
*398 in opposition to the motion for summary judgment plaintiff submitted her declaration wherein she stated inter alia: 2 Throughout the period of her employment at Lockheed, she received promotions, merit salary increases, achievement awards, and A’s and B’s on all of her job performance ratings. After plaintiff went to work for Cadam, and through 1988, all periodic appraisals of plaintiff’s work rated her performance as good; she received a promotion and merit salary increases. While plaintiff never was given an express promise that her employment would be terminated only for good cause, she believed that such a promise was implied because of her 23 years of service to Lockheed and Cadam, her promotions, and the salary increases which she received.
The motion for summary judgment was granted. Judgment was entered in favor of defendants and against plaintiff on all causes of action. Plaintiff appeals from the judgment.

I
Standard of Review
Summary judgment is proper where the evidence submitted by the moving party is sufficient to sustain a judgment in its favor and the opposing party does not present evidence sufficient to raise a triable issue of material fact.

Constructive Discharge
“[A]n employee who is forced to resign due to actions and conditions so intolerable or aggravated at the time of his resignation that a reasonable person in the employee’s position would have resigned, and whose employer had actual or constructive knowledge of the intolerable actions and conditions and of their impact upon the employee and could have remedied the situation, but did not, is constructively discharged. Absent a contract of employment, express or implied, the employee must also show, as in all tortious wrongful termination cases [citation], that the actions and conditions that caused the employee to resign were violative of public policy.”
(Zilmer
v.
Carnation Co.
(1989)
Plaintiff relied on both theories—breach of implied contract of employment and violation of public policy—to establish constructive discharge.
A
Breach of Implied Contract
The complaint alleged: At all times in the course of her employment by Lockheed and Cadam, plaintiff performed her job in a satisfactory manner; based on the length of her service, substantial pay increases and superior job evaluations, Lockheed and Cadam impliedly promised plaintiff that as long as she performed her job satisfactorily her employment would continue. Defendants breached said employment agreement by providing plaintiff with false evaluations of her performance as manager of employee services and demoting her from that position to member of financial staff, thereby making the conditions of plaintiff’s employment so intolerable that she was forced to resign.
Labor Code section 2922, which provides that an employment relationship of unspecified duration may be terminated at the will of either party, establishes a presumption of at-will employment. This presumption may be
*400
overcome by evidence of an implied agreement that the employment would continue indefinitely, pending the occurrence of some event such as the employer’s dissatisfaction with the employee’s services or the existence of a cause for termination.
(Foley
v.
Interactive Data Corp.
(1988)
Defendants contend they established the absence of an implied agreement that plaintiff’s employment would be terminated only for good cause by evidence that when plaintiff began working at Lockheed, and again when she was hired by Cadam, she signed a document which stated “no representation of employment conditions or rates of pay, other than set forth above, shall be valid.” As
Foley
notes, factors other than express terms are relevant in determining the existence of an implied employment agreement. Defendants presented no evidence showing the absence of such factors, while plaintiff’s declaration showed the presence of some of them (length of plaintiff’s service, promotions, salary increases, and superior performance ratings). Such evidence was sufficient to raise a triable issue regarding the existence of an implied agreement that plaintiff would not be discharged except for good cause. (See
Luck
v.
Southern Pacific Transportation Co.
(1990)
To prevail, however, plaintiff also must prove that the implied contract of employment was breached by conduct of defendants constituting constructive discharge.

“Whether conditions were so intolerable as to justify a reasonable employee’s decision to resign is normally a question of fact. [Citation.] Situations may exist, however, where the employee’s decision to resign is unreasonable as a matter of law.”
(Valdez
v.
City of Los Angeles
(1991)
The allegedly intolerable working conditions which forced plaintiff to resign consisted of an evaluation of plaintiff’s performance to which she
*401
objected and her demotion from manager of employee services to member of the financial staff. The fact that an employee received a poor performance rating will not support a finding of constructive discharge.
(Valdez
v.
City of Los Angeles, supra,
In another context our Supreme Court stated: “In order to properly manage its business, every employer must on occasion review, criticize, demote, transfer and discipline employees. . . . [(j[] . . . [W]hen the misconduct attributed to the employer is actions which are a normal part of the employment relationship, such as demotions, promotions, criticism of work practices, and frictions in negotiations as to grievances, an employee suffering emotional distress causing disability may not avoid the exclusive remedy provisions of the Labor Code by characterizing the employer’s decisions as manifestly unfair, outrageous, harassment, or intended to cause emotional disturbance resulting in disability.”
(Cole
v.
Fair Oaks Fire Protection Dist.
(1987)
B
Violation of Public Policy
The rule that an employee may pursue an action for tortious constructive discharge in violation of public policy is not limited to situations where, as a condition of employment, the employer coerces the employee to commit an act that violates public policy or restrains the employee from exercising a fundamental right. Such an action will lie wherever the basis of the discharge contravenes a fundamental public policy, such as the public policy against sex discrimination in employment.
(Rojo
v.
Kliger
(1990) 52
*402
Cal.3d 65, 90-91 [
The complaint alleged that at or about the time defendants demoted plaintiff, a female over the age of 40, from her position as manager of employee services, they replaced plaintiff with one David Laeha, a male under 40. It was further alleged: “To the extent that Soules’ age [and/or sex] . . . was a substantial factor contributing to defendants’ unsatisfactory rating of Soules, her demotion from manager of employees services department and the final wrongful constructive discharge of Soules, defendants’ aforesaid acts and conduct constituted employment discrimination because of age [and/or sex] which was a substantial factor in causing damages and injury to Soules” in violation of Government Code sections 12940, subdivisions (a) and (i), and 12941, subdivision (a). 4
In general, a single, isolated instance of employment discrimination is insufficient as a matter of law to support a finding of constructive discharge. Hence, a plaintiff alleging constructive discharge must show aggravating factors such as a continuous pattern of discrimination.
(Watson
v.
Nationwide Ins. Co.
(9th Cir. 1987)
The foregoing evidence presented by defendants establishes that plaintiff was not the victim of even a single, isolated instance of age or sex discrimination, much less the target of a pattern of continuous discrimination. Accordingly, summary judgment was properly granted on plaintiff’s cause of action for constructive discharge based on violation of public policy, 6 and on her causes of action for age and sex discrimination to the extent they are asserted independently and not as a basis of plaintiff’s claim of constructive discharge.
III
Causes of Action Sounding in Tort
In
Foley
v.
Interactive Data Corp., supra,
Plaintiff’s remaining tort causes of action (intentional infliction of emotional distress, negligent infliction of emotional distress, intentional interference with contractual relations, libel, slander, negligence, prima facie tort, *404 and conspiracy) are founded on defendants’ conduct which formed the basis of the causes of action for wrongful constructive discharge in breach of the contract of employment and the implied covenant of good faith and fair dealing: evaluating plaintiff’s job performance and demoting her.
It has been held that under
Foley
damages for emotional distress are not recoverable in a wrongful discharge action.
(Fidler
v.
Hollywood Park Operating Co.
(1990)
A defendant’s motion for summary judgment necessarily includes a test of the sufficiency of the complaint.
(Centinela Hospital Assn.
v.
City of Inglewood
(1990)
Disposition
The judgment is affirmed.
Johnson, J., and Woods (Fred), J., concurred.
Appellant’s petition for review by the Supreme Court was denied March 12, 1992.
Notes
The defendants are: Cadam, Inc., a subsidiary of Lockheed Corporation; Personal Cad Systems, Inc. (P-Cad), a corporation acquired by Cadam, Inc.; International Business Machines Corporation, which acquired the assets of both Cadam and P-Cad subsequent to plaintiff’s alleged constructive discharge; Ronald Egy, a P-Cad employee who was plaintiff’s supervisor; and James Pardee, an officer of P-Cad who was Egy’s supervisor.
The normal policy of liberal construction given to declarations opposing a motion for summary judgment does not apply where the declaration contradicts declarant’s earlier admissions in a deposition.
(Kerr
v.
Rose
(1990)
The same conduct on defendants’ part is alleged to constitute both breach of the employment contract and breach of the implied covenant of good faith and fair dealing inherent in the contract. Inasmuch as the nature and extent of the obligations imposed by the covenant depend on the contract and the parties’ justified expectations
(Sheppard
v.
Morgan Keegan & Co.
(1990)
Government Code section 12940 provides in pertinent part: “It shall be an unlawful employment practice, unless based upon a bona fide occupational qualification, or, except where based upon applicable security regulations established by the United States or the State of California: [5] (a) For an employer, because of the . . . sex of any person, ... to discharge the person from employment. . . or to discriminate against the person in compensation or in terms, conditions or privileges of employment. . . . [f] (i) For an employer . . . to fail to take all reasonable steps necessary to prevent discrimination and harassment from occurring.”
Government Code section 12941 reads in relevant part: “(a) It is an unlawful employment practice for an employer to refuse to hire or employ, or to discharge, dismiss, reduce, suspend, or demote, any individual over the age of 40 on the ground of age, except in cases where the law compels or provides for such action. . . .”
While replacement by someone younger, without more, does not support an inference of age discrimination, a substantial difference in the ages may be circumstantial evidence that
*403
gives rise to such inference.
(Maxfield
v.
Sinclair Intern.
(3d Cir. 1985)
The parties argue at length the issue whether defendants had actual or constructive knowledge of the intolerable conditions in plaintiff’s workplace which allegedly constituted constructive discharge. (See
