The plaintiff, Cynthia Fincher, is an African-American woman who was employed by the defendant, Depository Trust and Clearing Corporation (“DTCC”). She first held the position of product manager in the company’s International Tax Department. Thereafter, she was a Senior Auditor in the Financial/Operations Division of the company’s Audit Department. She resigned her employment on June 5, 2006. She subsequently brought suit in the United States District Court for the Southern *716 District of New York alleging that she was the victim of racial discrimination with respect to training opportunities, performance evaluations, and salary decisions during her time in the Audit Department. She also claimed that she was subjected to unlawful retaliation, a hostile work environment, and constructive discharge. Central to the latter three claims was Fincher’s contention that DTCC failed to investigate a complaint of discrimination that she allegedly made to the company’s senior director of employee relations.
Upon motion for summary judgment by DTCC, the district court (William H. Pauley, Judge) dismissed all of Fincher’s claims. Fincher appeals, arguing that DTCC’s failure to investigate her complaint of discrimination was itself an act of retaliation for making the discrimination complaint, and that it also contributed to a hostile work environment and her constructive discharge. Fincher also challenges the dismissal of her underlying discrimination claims on the ground that the district court improperly disregarded her deposition testimony that her manager at the defendant’s auditing department told her that she had been given inadequate training because of her race.
Accepting as we must at this stage of the proceedings that Fincher’s testimony to the effect that DTCC failed to investigate her complaint of racial discrimination is true, we nonetheless conclude that such a failure does not constitute an adverse employment action taken in retaliation for the filing of the same discrimination complaint. We also conclude that Fincher has failed to raise a triable issue of material fact as to her other claims of retaliation, or her claims of hostile work environment or constructive discharge. And inasmuch as Fincher has failed to support her underlying discrimination claims with more than a “scintilla of evidence,” summary judgment as to those claims was also proper.
We therefore affirm the judgment of the district court.
BACKGROUND
Fincher was employed by DTCC from February 2001 to June 2006. She worked as a product manager for the company’s International Tax Department until that position was eliminated in October 2004. She then moved to the company’s Financial/Operations Division of the Audit Department, where she was a Senior Auditor despite a lack of auditing experience. Between October 2004 and May 2006, in order to perform her duties, she relied upon several training courses provided to all auditors in her department, an audit manual, and guidance from co-workers.
Fincher testified that a co-worker on her first assignment worked with an experienced manager. Fincher’s first manager was, by contrast, a consultant unfamiliar with DTCC auditing procedures. And on one occasion, two of Fincher’s co-workers underwent unspecified training at a session that Fincher was not asked to attend.
In March 2005, Fincher received an official “Performance Appraisal” for her first two months in the Audit Department during 2004. It was signed by the Audit Department manager, Mark Hudson. It contained a handwritten note addressed to Fincher explaining that she had received “[a] good first review but further audit skill development is needed before more indepth [sic] feedback can be given. Keep trying----” 2004 Appraisal at 1. She received a mark of “Fully Competent” in every performance category for which she was graded. “Fully Competent” was in the middle of the grading scale, which ranged from “Unacceptable” to “Exceptional.”
*717 Fincher’s Performance Appraisal for 2005, compiled in this instance by Finch-er’s supervisor Donald Simpson, and then approved by Hudson on January 11, 2006, reflected a grade of “Requires Improvement” for most of the performance categories. For this performance evaluation, managers were instructed to give a grade of “Requires Improvement” only to employees in the bottom 5-15% of the company. Fincher’s review contained several “Fully Competent” evaluations, reserved for employees in the middle 55-65% of the company, but also several “Unacceptable” grades, reserved for the bottom 0-5% of employees. For example, Fincher received a grade of “Unacceptable” under “Demonstrates the technical/functional skills to do the job,” and under “Can be counted on to complete assignments with minimal follow-up.” 2005 Appraisal at 2, 3. A concluding section labeled “Manager’s Comments” asserted that Fincher frequently failed to meet deadlines and indicated that the department’s managers had a poor overall impression of Fincher’s work. Id. at 4.
On March 1, 2006, Fincher received by email attachment a Project Evaluation for a particular audit that she had completed. It reflected the grade of “Requires Improvement” in every category for which an evaluation was given.
On March 23, 2006, Fincher received a written “Performance Warning” from Hudson. It purported to document various perceived shortcomings in Fincher’s work, including failure to complete tasks “within allotted timeframes.” It also informed Fincher that she was “being placed on written warning for poor performance .... [Fjailure to immediately improve and sustain an acceptable level of performance, or further performance deficiencies, will result in further disciplinary action, up to and including termination of your employment.” Memorandum from Mark Hudson to Cynthia Fincher, “Written Performance Warning,” Mar. 23, 2006.
In late March 2006, Fincher had a conversation with Charles Smith, the Senior Director of Employee Relations at DTCC, in the lobby of their office building. They were professional and social acquaintances who occasionally lunched together. According to Fincher, she complained to Smith that “black people were set up to fail at [the Auditing] department because they were not provided and given the same training opportunities as the white employees.” Fincher Dep. 202. Smith’s recollection is different. 1
About one week later, Fincher and Smith had another conversation as to which their recollections also conflict. According to Fincher, she asked Smith whether he or his manager was planning to take action in response to the complaint of discrimination she had made during their first conversation. Smith told her that the complaint would not be addressed. 2
Fincher also testified to a conversation she had with her manager, Mark Hudson, in his office in May 2006. He “admitted to me,” she said, “that he was forced to write me up, and he ... had informed [Human *718 Resources Employee Elizabeth] Baez that I did not receive proper training, and he admitted that I was discriminated against.” Fincher Dep. 125. She said he said that “[she] was not the only one being discriminated against.” He allegedly named one Herb Fray as also having been subjected to discrimination. Id. 3
On June 5, 2006, Fincher resigned her employment. In a letter addressed to Baez, she said that her resignation was “due to [ ] racial discrimination,” including “receiving inadequate training.” Resignation Letter to Elizabeth Baez, June 5, 2006. The letter concluded: “I was forced out because of racial discrimination and because I am aware of the fact that the company did not act on racial discrimination complaints brought forth by myself and others.” Id.
In a second letter, also dated June 5, addressed to Meriam Murphy-Jones, a Vice President in the Audit Department, Fincher announced her resignation, explaining that she had been “offered a position as Vice-President at another firm; therefore my last day will be on Friday June 16th.” Resignation Letter to Meriam Murphy-Jones, June 5, 2006.
Then, without first making a complaint to the Equal Employment Opportunity Commission (“EEOC”), Fincher brought this employment discrimination action against DTCC in the United States District Court for the Southern District of New York. She alleges violations of the Civil Rights Act of 1991, 42 U.S.C. § 1981, Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e et seq. (“Title VII”), New York State Executive Law § 296, and the New York City Administrative Code § 8-502 (the New York State and New York City Human Rights Laws, or the HRL and CHRL, respectively).
Count I of her complaint alleges that she was subjected to racial discrimination with respect to training opportunities, performance reviews, and salary decisions. Count II alleges that she was the victim of retaliation for making a complaint of racial discrimination to Smith, and that she was subjected to a hostile work environment. Both the retaliation claim and the hostile work environment claim were based on DTCC’s alleged failure to investigate Fincher’s complaint of racial discrimination to Smith. Count II of the complaint also asserted a claim of constructive discharge based on the allegations of retaliation and hostile work environment made in the same claim for relief. See Compl. ¶ 17 (“[Fincher] was compelled to leave the firm for these reasons.”). The complaint did not indicate which alleged conduct she was challenging under which of the statutes she invoked.
DTCC moved for summary judgment. On September 17, 2008, the district court issued a Memorandum and Order granting DTCC’s motion and dismissing Fincher’s claims in their entirety.
Fincher v. Depository Trust & Clearing Corp.,
No. 06 Civ. 9959,
As to her discrimination claims under 42 U.S.C. § 1981, the district court concluded that Fincher had failed to show that the circumstances of her training, performance evaluations, or compensation gave rise to
*719
an inference of discrimination, and that she had therefore failed to establish a
prima facie
case of discrimination.
Id.,
Turning next to Fincher’s retaliation, hostile work environment, and constructive discharge claims under section 1981, the district court concluded that Fincher had failed to show that she suffered any retaliation for complaining of discrimination to Smith because DTCC’s failure to investigate that complaint was not an adverse employment action.
Id.,
Finally, the district court concluded that Fincher had failed to establish a claim under the New York State and City Human Rights laws, because the court was of the view that discrimination claims under those laws were analyzed under the same standards as those used for claims brought under section 1981.
Id.,
Fincher argues on appeal that DTCC’s failure to investigate her alleged complaint of discrimination constituted retaliation for her bringing that same complaint. She also argues that the failure to investigate her complaint, in light of the “totality of the circumstances,” created a hostile work environment, and amounted to a constructive discharge. Finally, she argues that the district court did not give sufficient consideration to her testimony about Hudson’s alleged admission to her that she was the victim of racial discrimination. 4
*720 DISCUSSION
I. Standard of Review
“We review a district court’s grant of summary judgment
de novo,
construing the evidence in the light most favorable to the non-moving party and drawing all reasonable inferences in its favor.”
Allianz Ins. Co. v. Lemer,
II. Retaliation
A. Federal Retaliation Claims
Retaliation claims made under 42 U.S.C. § 1981, like those made under Title VII, are evaluated using a three-step burden-shifting analysis.
5
See, e.g., Taitt v. Chemical Bank,
In this case, the district court granted summary judgment in favor of DTCC based on the court’s conclusion that Fincher had failed to establish a prima facie case of unlawful retaliation. In order to establish such a prima facie case,
a plaintiff must adduce evidence sufficient to permit a rational trier of fact to find (1) that [s]he engaged in protected [activity] under [the anti-discrimination statutes], (2) that the employer was aware of this activity, (3) that the employer took adverse action against the plaintiff, and (4) that a causal connection exists between the protected activity and the adverse action, i.e., that a retaliatory motive played a part in the adverse employment action.
Kessler v. Westchester County Dep’t of Soc. Servs.,
*721
The district court concluded that Fincher had failed to establish a
prima facie
case of retaliation because even accepting, for purposes of summary judgment, her testimony that she complained of discrimination to Smith in late March 2006 and that the company failed to investigate that complaint, such a failure to investigate did not constitute an adverse employment action. The anti-retaliation law “protects an individual not from all retaliation, but from retaliation that produces an injury or harm.”
Burlington N. & Santa Fe By. Co. v. White,
[A] plaintiff must show that a reasonable employee would have found the challenged action materially adverse, which in this context means it well might have dissuaded a reasonable worker from making or supporting a charge of discrimination. We speak of material adversity because we believe it is important to separate significant from trivial harms.
Id.
at 68,
Because we must resolve all factual ambiguities against DTCC, we accept for purposes of this appeal that Fincher made a complaint of discrimination to Smith in late March 2006 and that Smith was aware that Fincher was making a complaint. Fincher has thus satisfied the first two elements of her prima facie case. We further accept for purposes of this appeal that the company failed to investigate Fincher’s complaint. We agree with the district court, however, that any such failure did not constitute an adverse employment action against Fincher.
We have said that “there are no bright-line rules” with respect to what constitutes an adverse employment action for purposes of a retaliation claim, and therefore “courts must pore over each case to determine whether the challenged employment action reaches the level of ‘adverse.’ ”
Wanamaker v. Columbian Rope Co.,
“Affirmative efforts to punish a complaining employee are at the heart of any retaliation claim.”
Id.,
*722
We do not mean to suggest that failure to investigate a complaint cannot ever be considered an adverse employment action for purposes of a retaliation claim. It can be if the failure is in retaliation for some separate, protected act by the plaintiff. In
Rochon v. Gonzales,
Here, by contrast, a reasonable employee in Fincher’s place had nothing to lose by bringing this complaint, or another one following it, because the result of bringing the complaint and not bringing the complaint under the conditions alleged was the same: the complaint would not be investigated. No action has been attributed to the defendant here except for the disposition — or lack thereof — of the same complaint that allegedly provoked the retaliatory response.
A contrary rule could have odd consequences. A person not in fact discriminated against could complain of discrimination nonetheless. If the miffed accused employer were, because of his or her anger, to decline to investigate what was in fact a false claim, the employee might have a viable suit for retaliatory failure to investigate. We do not think that to be the law.
Summary judgment dismissing Finch-er’s retaliation claims under 42 U.S.C. § 1981 was therefore proper. 8
*723 B. State and City Retaliation Claims
The dismissal of Fincher’s state- and city-law retaliation claims must also be affirmed, notwithstanding that it was based in part on the court’s arguably incorrect view that the city-law claims were to be “analyzed under the same standards as § 1981.”
Fincher,
The functional difference, if any, between the CHRL standard and that used for federal and state retaliation claims has never been fully articulated. The Appellate Division, First Department, has said that the CHRL “rejects a materiality requirement,” while under
Burlington,
federal retaliation claims must involve an action by the employer that is “materially adverse.”
Compare Williams,
It is unnecessary for us to determine on this appeal whether or to what extent the “reasonably likely to deter” standard of the CHRL differs from Burlington’s “well might have dissuaded” test. Fincher has not made any argument touching on the CHRL in her brief or at oral argument. Thus any assertion that she might have made to the effect that her retaliation claim should survive the arguably broader CHRL inquiry has been abandoned.
See United States v. Joyner,
III. Hostile Work Environment and Constructive Discharge
In order to establish a hostile work environment claim under 42 U.S.C. § 1981, a plaintiff “must show that the workplace was so severely permeated with
*724
discriminatory intimidation, ridicule, and insult that the terms and conditions of her employment were thereby altered.”
Alfana v. Costello,
Fincher argues that DTCC’s failure to investigate her discrimination complaint, considered in light of “the totality of the circumstances,” created a hostile work environment for her. But the failure to investigate did not by itself alter the terms and conditions of Fincher’s employment; rather, it preserved the very circumstances that were the subject of the complaint. Therefore the failure to investigate Fincher’s complaint could not itself have contributed to or constituted a hostile work environment.
Cf. Robles v. Argonaut Rest. & Diner, Inc.,
No. 05 Civ. 5553,
Indeed, although this Circuit has not ruled on the question, in the analogous context of hostile work environment claims based on allegations of sexual harassment, “[federal] courts (including district courts in this circuit) appear to have uniformly rejected the notion that a failure adequately to remediate sexual harassment itself constitutes an act that may contribute to a hostile work environment claim.”
Chan v. N.Y. City Transit Auth.,
No. 03 Civ. 6239,
Fincher does not identify the facts to which her phrase, “the totality of the circumstances,” refers. The evidence that she presented to the district court was to the effect that on at least one occasion, two of her co-workers were invited, without her, for unspecified training, and that on at least one occasion, one of her co-workers was assigned to work with a supervisor who was better qualified than Fincher’s supervisor. We conclude that these sporadic events, none of which was personally abusive, as a matter of law do not amount to a series of abusive and pervasive incidents of discrimination, nor do they include a single extraordinary one. The hostile work environment claim fails. 10
*725
The district court also correctly granted summary judgment dismissing Fincher’s constructive discharge claim. Fincher’s complaint, which does not raise constructive discharge as a separate allegation, makes clear that the acts which she alleges gave rise to a hostile work environment were the same as those upon which her constructive discharge claim was based. Where an alleged constructive discharge stems from an alleged hostile work environment, a plaintiff “must show working conditions so intolerable that a reasonable person would have felt compelled to resign.”
Pa. State Police v. Suders,
IV. Underlying Section 1981 Discrimination Claims
The district court granted summary judgment dismissing Fincher’s underlying section 1981 discrimination claims because it concluded that Fincher had presented no evidence giving rise to an inference of discrimination with respect to her training, salary, or performance evaluations. On appeal, Fincher makes only one argument challenging this conclusion: that the district court gave insufficient consideration to her testimony about Hudson’s alleged admission that, she had been the victim of discrimination with respect to training.
11
Fincher emphasizes that Hudson’s alleged statements were not hearsay, although the district court gave no indication that it regarded the statements as being such and did not rule them inadmissible. Rather, the district court appeared to disbelieve Fincher’s assertion that Hudson had made the statements attributed to him: “Fincher’s testimony that Hudson believed she and another co-worker had been discriminated against is not supported by anything other than Fincher’s
ipse dixit.” Fincher,
To be sure, there is an exception for “the rare circumstance where the plaintiff relies almost exclusively on his own testimony, much of which is contradictory and incomplete.”
Jeffreys v. City of N.Y.,
That exception is not applicable in this case, however. Fincher relies exclusively upon her own testimony for the assertion that Hudson made the disputed statements, but her testimony was not contradictory or rife with inconsistencies such that it was facially implausible. Discrimination cases also tend to be particularly ill-suited to the assessment of a plaintiffs credibility at the summary judgment stage, because in such cases “the only direct evidence available very often centers on what the defendant allegedly said or did,” and “the defendant will rarely admit to having said or done what is alleged, and ... third-party witnesses are by no means always available.”
Danzer v. Norden Sys., Inc.,
Although we thus accept for purposes of this appeal that Fincher’s account of her conversation with Hudson is accurate, we conclude that his remarks do not provide an adequate evidentiary basis for the denial of the motion for summary judgment. Summary judgment cannot be defeated by the presentation by the plaintiff of but a “scintilla of evidence” supporting her claim.
Anderson v. Liberty Lobby, Inc.,
The disputed remarks were, moreover, a purported concession that Fincher was discriminated against; they were not themselves discriminatory.
13
Summary judgment might not have been justified were Hudson’s alleged remarks themselves imbued with discriminatory animus, rather than a report of purportedly discriminatory action.
See, e.g., Forman v. Small,
CONCLUSION
For the foregoing reasons, we affirm the judgment of the district court.
Notes
. Although we are required to and do credit Fincher's account at this stage of the proceedings, we note that according to Smith, Finch-er only made a casual remark that "if you are white they hold your hand and if you are black, they don't.” Smith testified that he did not understand Fincher to be lodging a complaint of discrimination. Smith Dep. 124.
. According to Smith, Fincher simply repeated her remark that "if you are white they hold your hand and if you are black, they don’t.” Smith Dep. 125. Smith testified that he asked Fincher whether she was making a serious complaint, and that, when she indicated that she was, Smith "put the wheels in motion to investigate.” Id.
. Hudson, who was not deposed, submitted an affidavit in which he denied that the conversation took place.
. A fourth argument made by Fincher, that summary judgment should not have been granted because Smith allegedly contradicted himself in the course of his deposition, does not warrant extended discussion. The contradiction identified by Fincher is the tension between Smith's initial testimony that he did not learn that Fincher had complained of racial discrimination until she resigned, Smith Dep. 48, and his later testimony that he had heard her complain about discrimination before she resigned but had not thought that she was making a serious complaint, Smith Dep. 124. First, to the extent this tension can be considered an inconsistency, it is immaterial, because the district court accepted, for purposes of summary judgment, Fincher’s testimony that her late-March 2006 remarks to Smith constituted an actual complaint that he and the company failed to investigate, and we make the same assumption. Second, Smith’s alleged mendacity could not in itself constitute sufficient evidence to establish a
prima facie
case of discrimination.
Cf. Reeves v. Sanderson Plumbing Prods., Inc.,
. Fincher does not challenge the district court’s finding that her Title VII claims are barred because she failed to file an EEOC complaint, and we do not review that finding here.
See, e.g., United States v. Joyner,
. Although we refer to an "adverse employment action” in applying the test,
see also, e.g., Schiano v. Quality Payroll Sys., Inc.,
. Of course, in Rochon, the separate complaint that was allegedly ignored as a result of the filing of the initial complaint was of a particularly serious nature. We need not decide here whether an employer’s failure to investigate a complaint of discrimination in retaliation for the filing of a separate, earlier complaint of discrimination would rise to the level of an adverse employment action. That question is simply not before us.
. Because we conclude that the failure to investigate a complaint cannot be considered an adverse employment action taken in retaliation for the filing of that same complaint, we do not address DTCC’s argument in the alternative, which the district court also did not reach, that even if the failure to investigate Fincher’s complaint could be considered an adverse employment action, she could not and did not demonstrate the requisite causal connection between her filing the complaint *723 and DTCC's failure to investigate it to make a prima facie case of retaliation.
. The New York Court of Appeals has not yet ruled on the issue.
. Several federal district courts, as well as the New York Appellate Division, First Department, but not the New York Court of Appeals, have concluded that “less egregious conduct than that required under Title VII [or § 1981] may support a hostile work environment claim under the [ ]CHRL.“
Panzarino v. Deloitte & Touche LLP,
No. 05 Civ. 8502,
*725
. Fincher drew the connection between her argument about Hudson’s alleged admission and her underlying discrimination claims at oral argument, although that connection was not drawn, at least explicitly, in her brief.
. That is not to say that Hudson’s alleged remarks themselves were not conclusory. See infra.
. Moreover, even as a purported concession the disputed remarks were indirect, with Hudson referring vaguely to the discriminatory motives of others at the company, not his own, as compelling his actions toward Finch-er.
