OPINION AND ORDER

JOHN G. KOELTL, District Judge:

Pro se plaintiff Nicole Lawtone-Bowles brings this action against the City of New York, Department of Sanitation ("DSNY") and Kadaya Pouncie, alleging employment discrimination, retaliation, failure to accommodate, assault, and negligent supervision and retention under various provisions of state and federal law.1 The DSNY has moved to dismiss the plaintiff's claims against it under Rules 12(b)(1) and 12(b)(6) of the Federal Rules of Civil Procedure.2

I.

In deciding a motion to dismiss pursuant to Rule 12(b)(6), the allegations in the complaint are accepted as true, and all reasonable inferences must be drawn in the plaintiff's favor. McCarthy v. Dun & Bradstreet Corp., 482 F.3d 184, 191 (2d Cir.2007). The Court's function on a motion to dismiss is "not to weigh the evidence that might be presented at a trial but merely to determine whether the complaint itself is legally sufficient." Goldman v. Belden, 754 F.2d 1059, 1067 (2d Cir.1985). The Court should not dismiss the complaint if the plaintiff has stated "enough facts to state a claim to relief that is plausible on its face." Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007). "A claim has facial plausibility when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged." Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009). While the Court should construe the factual allegations in the light most favorable to the plaintiff, "the tenet that a court must accept as true all of the allegations contained in the complaint is inapplicable to legal conclusions." Id.

When faced with a pro se complaint, the Court must "construe [the] complaint liberally and interpret it to raise the strongest arguments that it suggests." Chavis v. Chappius, 618 F.3d 162, 170 (2d Cir.2010) (citation and internal quotation marks omitted). "Even in a pro se case, however, ... threadbare recitals of the elements of a cause of action, supported by mere conclusory statements, do not suffice." Id. (citation omitted). Thus, although the Court is "obligated to draw the most favorable inferences" that the complaint supports, it "cannot invent factual allegations that [the plaintiff] has not pled." Id.; see also Seymore v. Dept. of Corr. Servs., No. 11 Civ. 2254, 2014 WL 641428, at *1 (S.D.N.Y. Feb. 18, 2014).

When presented with a motion to dismiss pursuant to Rule 12(b)(6), the Court may consider documents that are referenced in the complaint, documents that the plaintiff relied on in bringing suit and that are either in the plaintiff's possession or that the plaintiff knew of when bringing suit, or matters of which judicial notice may be taken. See Chambers v. Time Warner, Inc., 282 F.3d 147, 153 (2d Cir.2002); see also Winfield v. Citibank, N.A., 842 F.Supp.2d 560, 564 (S.D.N.Y. 2012).

To survive a motion brought under Rule 12(b)(1), the plaintiff bears the burden of proving the Court's jurisdiction by a preponderance of the evidence. Makarova v. United States, 201 F.3d 110, 113 (2d Cir.2000). Moreover, in considering such a motion, the Court generally must accept the material factual allegations in the complaint as true, but the Court does not draw all reasonable inferences in the plaintiff's favor. J.S. ex rel. N.S. v. Attica Cent. Sch., 386 F.3d 107, 110 (2d Cir.2004); Graubart v. Jazz Images, Inc., No. 02 Civ. 4645, 2006 WL 1140724, at *2 (S.D.N.Y. Apr. 27, 2006). Indeed, where jurisdictional facts are disputed, the Court has the power and the obligation to consider matters outside the pleadings, such as affidavits, documents, and testimony, to determine whether jurisdiction exists. See APWU v. Potter, 343 F.3d 619, 627 (2d Cir.2003).

II.

The following facts are accepted as true for purposes of this motion to dismiss.

A.

In June 2012,3 the plaintiff was employed by the DSNY in a probationary capacity as a Sanitation Enforcement Agent. (See Am. Compl. at 3, 7; LaRose Decl., Ex. 1 at 6.) The plaintiff alleges that she made a complaint to her supervisor against Defendant Pouncie, a fellow DSNY employee, after a verbal altercation with Pouncie on June 4, 2012. (See Am. Compl. at 7.) Two days after the plaintiff complained about Pouncie, on June 6, 2012, Pouncie assaulted her during her shift. (See Am. Compl. at 3, 7.) On the same day, the plaintiff was suspended from her employment. (Am. Compl. at 9.) On June 21, 2012, the plaintiff's probationary employment with the DSNY was terminated. (See Am. Compl. at 7, 9; LaRose Decl., Ex. 1 at 6.) The plaintiff alleges that prior to the assault, the DSNY had knowledge that Pouncie "had a drug problem and was in several work place violence incidents with other employees." (Am. Compl. at 9; see also Am. Compl. at 3.)

The plaintiff also alleges that at some time during her probationary employment with the DSNY, she was ordered to work on foot patrol in the rain. (Am. Compl. at 9.) In response, the plaintiff informed her supervisor that it would be difficult for her to work on foot patrol because she has degenerative joint disease in her knees. (See Am. Compl. at 9.) The plaintiff's supervisor nevertheless required the plaintiff to work the foot patrol shift, which the plaintiff was unable to complete because of swelling in her knees. (Am. Compl. at 9.)

Finally, the plaintiff alleges that at some unspecified time during her training, she "filed an[] EEO complaint against an employee... because he constantly verbally abused [her]." (Am. Compl. at 9; see also Am. Compl. at 3.) Her EEO complaint was denied. (Am. Compl. at 9.)

B.

On July 10, 2012, the plaintiff filed an Article 78 petition in the New York State Supreme Court, New York County, alleging, among other things, that her termination from the DSNY was an impermissible disability-related discharge, and that the DSNY had failed to provide her with a reasonable accommodation for her disability. (LaRose Decl., Ex. 1 at 1-2.)4 The court concluded that the record did not yield any inference that the plaintiff's termination was for any improper reason, and that altercations between the plaintiff and her peers and supervisors provided sufficient reason for her termination. See Lawtone-Bowles v. City of N.Y. Dep't of Sanitation, No. 401513/12, at 2-3 (N.Y.Sup.Ct. Feb. 27, 2013). Accordingly, the plaintiff's Article 78 petition was denied. Id. at 3.

On July 11, 2012, the plaintiff filed a complaint with the New York State Division of Human Rights ("SDHR"), alleging that her termination arose from discrimination on the basis of age, arrest record, conviction record, disability, domestic violence victim status, marital status, race, ethnicity, and sex, and that her termination was also due to unlawful retaliation for a complaint that the plaintiff had filed against other DSNY employees before she was fired. (LaRose Decl., Ex. 3 at 2-3.)5 The plaintiff also alleged that the DSNY failed to accommodate her disability. (LaRose Decl., Ex. 3 at 3-4.) The SDHR concluded that there was no probable cause to believe that the plaintiff's probationary employment was terminated for any unlawful reason and dismissed the plaintiff's complaint. See Determination and Order After Investigation, Lawtone-Bowles v. City of N.Y., Dep't of Sanitation, No. 10156089, at 3 (N.Y.S.Hum.Rts.Div. Jan. 3, 2013). The plaintiff did not seek judicial review of this determination.

On March 4, 2013, the plaintiff filed this lawsuit, in which she alleged that she was assaulted, denied accommodation for disability, and unlawfully terminated. The DSNY moved to dismiss the Complaint, arguing that the plaintiff's claims were foreclosed by the determination in the Article 78 proceeding in state court, and that the plaintiff had failed to state any claims upon which relief could be granted. In her opposition to the motion, the plaintiff indicated that she wished to amend her Complaint to include additional claims and allegations. The Court therefore granted the plaintiff leave to file an amended complaint and denied the DSNY's motion without prejudice. On October 8, 2013, the plaintiff filed her Amended Complaint using a form complaint. In her Amended Complaint, the plaintiff lists numerous statutes that she claims were violated by virtue of her termination by the DSNY, including Title VII, the ADEA, the ADA, the NYSHRL, and the NYCHRL. The Amended Complaint also includes tort claims against both defendants. The DSNY now moves to dismiss all claims against it.

III.

The DSNY proffers three grounds upon which the plaintiff's claims against it should be dismissed. First, the DSNY argues that the plaintiff is collaterally estopped from bringing her discrimination, retaliation, and failure to accommodate claims in this Court. Next, the DSNY argues that the plaintiff's claims must be dismissed because the plaintiff has failed to plead sufficient facts to state a plausible claim for relief. Finally, the DSNY argues that the Court lacks jurisdiction over the plaintiff's state- and city-law discrimination claims because these claims are barred by the doctrine of election-of-remedies. The plaintiff has not responded to any of the DSNY's arguments. Instead, the plaintiff has submitted an affirmation in opposition to the DSNY's motion in which she attests that a New York State Workers' Compensation Board hearing has been scheduled to address her injuries, and that this proves that she was terminated for an impermissible reason.6

A.

The DSNY argues that the plaintiff's discrimination, retaliation, and failure-to-accommodate claims must be dismissed on the merits because they are barred by the doctrine of collateral estoppel.7 The federal full faith and credit statute provides, in relevant part, that the "judicial proceedings of any court of any... State ... shall have the same full faith and credit in every court within the United States ... as they have by law or usage in the courts of such State ... from which they are taken." 28 U.S.C. § 1738. Under the full faith and credit statute, "a federal court must give to a state-court judgment the same preclusive effect as would be given that judgment under the law of the State in which the judgment was rendered." Migra v. Warren City Sch. Dist. Bd. of Educ., 465 U.S. 75, 81, 104 S.Ct. 892, 79 L.Ed.2d 56 (1984). Therefore, New York law governs this Court's collateral estoppel analysis.

The doctrine of collateral estoppel — also known as issue preclusion — prohibits a party from re-litigating an issue in certain circumstances. Under New York law, collateral estoppel bars claims where "(1) the issue in question was actually and necessarily decided in a prior proceeding, and (2) the party against whom the doctrine is asserted had a full and fair opportunity to litigate the issue in the first proceeding." Colon v. Coughlin, 58 F.3d 865, 869 (2d Cir.1995) (citations omitted); see also Phifer v. City of New York, 289 F.3d 49, 56 (2d Cir.2002). "Collateral estoppel is a flexible doctrine and whether to apply it in a particular case depends on general notions of fairness involving a practical inquiry into the realities of the litigation." Peterson v. City of New York, No. 11 Civ. 3141, 2012 WL 2148181, at *1 (S.D.N.Y. June 13, 2012) (citation omitted). The DSNY, as the party asserting issue preclusion, bears the burden of showing that the identical issue was previously decided, while the plaintiff bears the burden of showing the absence of a full and fair opportunity to litigate in the prior proceeding. Colon, 58 F.3d at 869.

The New York test for collateral estoppel has been met with respect to the plaintiff's claims arising under the ADA because those claims are predicated on issues litigated and decided in the plaintiff's Article 78 proceeding — namely, whether the plaintiff was fired because of her disability or because she requested accommodation for her disability, and whether the DSNY failed to accommodate her disability. In her Article 78 petition, the plaintiff alleged that she brought her disability to her supervisors' attention and was subsequently denied accommodation and terminated. (See LaRose Decl., Ex. 1 at 1-2.) The plaintiff has made the same factual allegations before this Court — namely, that she brought her disability to the attention of her supervisor, was not offered any accommodation, and thereafter was suspended and then terminated. (See Am. Compl. at 9.) The state court concluded that there was no evidence that the plaintiff had been terminated because of her disability or for any unlawful reason. Lawtone-Bowles, No. 401513/12, at 2-3. The issues underlying the plaintiff's ADA claims in this action are therefore identical to issues that were actually and necessarily decided in the plaintiff's Article 78 proceeding. Because the plaintiff does not dispute that she had a full and fair opportunity to litigate these issues in her Article 78 proceeding or that Article 78 court determinations have preclusive effect in contexts such as this one, both prongs of the New York test for collateral estoppel have been met, and the plaintiff's claims for discrimination, retaliation, and failure to accommodate under the ADA must be dismissed.8

B.

The DSNY next argues that the plaintiff's claims against it must be dismissed in their entirety under Rule 12(b)(6) because the plaintiff has failed to state any claims upon which relief may be granted. The Court addresses the DSNY's arguments with respect to each individual remaining claim in turn.

1.

The plaintiff checked a box on her form complaint indicating that some of her claims arise under Title VII. (Am. Comp. at 1.) Elsewhere, she checked boxes indicating that she alleges that her termination was the result of discrimination based on, among other categories, race, color, sex, religion, and national origin. (Am. Compl. at 2-3.)

To state a claim for employment discrimination under Title VII, a plaintiff must allege that she suffered an adverse employment action because of her race, color, religion, sex, or national origin. 42 U.S.C. § 2000e-2(a). Although a plaintiff is not required to allege facts establishing a prima facie case of discrimination to survive a motion to dismiss, Swierkiewicz v. Sorema N.A., 534 U.S. 506, 508, 122 S.Ct. 992, 152 L.Ed.2d 1 (2002), a plaintiff must plead "sufficient factual matter, accepted as true, to state a claim to relief that is plausible on its face." Iqbal, 556 U.S. at 678, 129 S.Ct. 1937 (citation and internal quotation marks omitted); see also Rullan v. N.Y. City Sanitation Dep't, No. 13 Civ. 5154, 2014 WL 2011771, at *6 (S.D.N.Y. May 16, 2014).

In this case, the plaintiff alleges that she is a member of multiple protected classes, but she has not alleged any facts that yield an inference that she was discharged because of her membership in these protected classes. See, e.g., Patane v. Clark, 508 F.3d 106, 112 (2d Cir.2007) (affirming dismissal of a Title VII claim for failure to allege discriminatory animus based on sex); Williams v. Wellness Med. Care, P.C., No. 11 Civ. 5566, 2013 WL 5420985, at *6 (S.D.N.Y. Sept. 27, 2013) (dismissing Title VII claims for failure to allege discriminatory animus based on race); Jenkins v. N.Y. City Dep't of Educ., No. 10 Civ. 6159, 2011 WL 5451711, at *4 (S.D.N.Y. Nov. 9, 2011) (dismissing Title VII claims for failure to allege discriminatory animus based on race or sex), aff'd, 508 Fed.Appx. 66 (2d Cir.2013) (summary order). Although a plaintiff need not allege each element of a prima facie claim to survive a motion to dismiss, the facts alleged must support a plausible inference of discrimination on the basis of a protected characteristic. Rullan, 2014 WL 2011771, at *6. Even construing the plaintiff's pro se Complaint liberally to raise the strongest arguments it suggests, the plaintiff has failed to state a claim that is plausible on its face. See Saidin v. N.Y. City Dep't of Educ., 498 F.Supp.2d 683, 687 (S.D.N.Y. 2007), reconsid. denied, 245 F.R.D. 175 (S.D.N.Y.2007). Her claim for employment discrimination under Title VII must therefore be dismissed. See Patane, 508 F.3d at 112; Rullan, 2014 WL 2011771, at *6; Williams, 2013 WL 5420985, at *6; Jenkins, 2011 WL 5451711, at *4; Jackson v. NYS Dep't of Labor, 709 F.Supp.2d 218, 226-27 (S.D.N.Y.2010), appeal dismissed, 431 Fed.Appx. 21 (2d Cir.2011) (summary order).

2.

The plaintiff also alleges employment discrimination in violation of the ADEA. (See Am. Compl. at 1, 3.) To plead a claim of age discrimination under the ADEA, the plaintiff must allege sufficient facts to support a plausible inference that she suffered an adverse employment action because of her age. 29 U.S.C. § 623(a); see also Caskey v. Cnty. of Ontario, 560 Fed.Appx. 57, 58, 2014 WL 1099232, at *1 (2d Cir.2014) (summary order) (citation omitted).

The plaintiff, who was born on December 4, 1971, (see Am. Compl. at 3), alleges that she was within a protected class for ADEA purposes, see 29 U.S.C. § 631(a) ("The prohibitions in this chapter shall be limited to individuals who are at least 40 years of age."), but she fails to allege any facts supporting an inference of adverse employment action due to her membership in this protected class. The sine qua non of a discrimination claim is that the discrimination was because of a protected characteristic. Patane, 508 F.3d at 112; Das v. Duane Reade, No. 14 Civ. 1717, 2014 WL 1894359, at *4 (E.D.N.Y. May 8, 2014). Because the plaintiff has failed to allege any facts supporting an inference of age discrimination, her ADEA claim must be dismissed.9 See, e.g., Das, 2014 WL 1894359, at *4; Stoner v. Young Concert Artists, Inc., No. 13 Civ. 4168, 2014 WL 661424, at *6-7 (S.D.N.Y. Feb. 7, 2014); Ercole v. LaHood, No. 07 Civ. 2049, 2011 WL 1205137, at *10 (E.D.N.Y. Mar. 29, 2011), aff'd, 472 Fed.Appx. 47 (2d Cir. 2012) (summary order), cert. denied, ___ U.S. ___, 133 S.Ct. 1479, 185 L.Ed.2d 380 (2013).

3.

The plaintiff alleges that her suspension and termination constituted unlawful retaliation under Title VII and the ADEA.10 To state a claim for retaliation under either Title VII or the ADEA, a plaintiff must plead facts tending to show that: "(1) she participated in a protected activity known to the defendant; (2) the defendant took an employment action disadvantaging her; and (3) there exists a causal connection between the protected activity and the adverse action." Patane, 508 F.3d at 115 (citation omitted) (Title VII); see also Mabry v. Neighborhood Defender Serv., 769 F.Supp.2d 381, 397 (S.D.N.Y.2011) (ADEA). "With respect to the first element, participation in protected activity, the plaintiff need not establish that the conduct she opposed was actually a violation of [the statute], but only that she possessed a good faith, reasonable belief that the underlying employment practice was unlawful under that statute." Galdieri-Ambrosini v. Nat'l Realty & Dev. Corp., 136 F.3d 276, 292 (2d Cir.1998) (citations and internal quotation marks omitted); see also Dinicola v. Chertoff, No. 05 Civ. 4968, 2007 WL 1456224, at *5 (E.D.N.Y. May 16, 2007). The reasonableness of the plaintiff's belief is to be evaluated in light of the totality of the circumstances. Galdieri-Ambrosini, 136 F.3d at 292.

Here, the plaintiff alleges that she "filed an[] EEO complaint against an employee while in training because he constantly verbally abused [her]," (Am. Compl. at 9; see also Am. Compl. at 3), and that she "filed a verbal complaint against [Defendant Pouncie] with [Pouncie's] supervisor because [Pouncie] was rude and obnoxious to her when [they] had to work together." (Am. Compl. at 7.) Nothing about the alleged EEO complaint yields any basis for concluding that the plaintiff had an objectively reasonable belief that the conduct she was complaining about had anything to do with her membership in a protected class. See, e.g., McManamon v. Shinseki, No. 11 Civ. 7610, 2013 WL 3466863, at *5 (S.D.N.Y. July 10, 2013); Santucci v. Veneman, No. 01 Civ. 6644, 2002 WL 31255115, at *4-5 (S.D.N.Y. Oct. 8, 2002); cf. Freeman v. Dep't of Envtl. Protection, No. 10 Civ. 1555, 2013 WL 817221, at *10 (E.D.N.Y. Feb. 5, 2013) (Report and Recommendation of the Magistrate Judge) (collecting cases), adopted by 2013 WL 801684 (E.D.N.Y. Mar. 5, 2013); Springle v. Metro. Transp. Auth., No. 06 Civ. 734, 2008 WL 331362, at *11 (S.D.N.Y. Feb. 1, 2008). Where, as here, the plaintiff "[m]ere[ly] complain[s] of unfair treatment by an individual," there is no basis for a finding of unlawful retaliation. Filippi v. Elmont Union Free Sch. Dist. Bd. of Educ., No. 09 Civ. 4675, 2012 WL 4483046, at *16 (E.D.N.Y. Sept. 27, 2012). Even construing the Amended Complaint liberally, the plaintiff has failed to allege a plausible claim of retaliation in violation of Title VII or the ADEA, and her retaliation claims must therefore be dismissed.

C.

For the foregoing reasons, all federal claims against the DSNY must be dismissed.11 In addition to her federal claims, the plaintiff brings several claims against the DSNY and Pouncie under state law. These include claims for discrimination under the NYSHRL and the NYCHRL, and tort claims for assault and negligent supervision and retention. (See Am. Compl. at 1, 3, 7, 9.) The DSNY argues that the state-law discrimination claims against the DSNY should be dismissed under the election-of-remedies doctrine, see N.Y. Exec. Law § 297(9) and N.Y.C. Admin. Code § 8-502(a); that any claim against the DSNY for vicarious liability stemming from the alleged assault should be dismissed for failure to state a claim under Rule 12(b)(6); and that, although Pouncie has not been served and counsel for the DSNY has not appeared on Pouncie's behalf, all claims against Pouncie should be dismissed sua sponte for the reasons that apply to the claims against the DSNY. The DSNY proffers no basis for dismissal of the negligent supervision and retention claims, which it appears to have overlooked.12

A district court may decline to exercise supplemental jurisdiction over state-law claims if "the district court has dismissed all claims over which it has original jurisdiction." 28 U.S.C. § 1367(c). When all federal claims are eliminated before trial, the balance of factors to be considered — including judicial economy, convenience, fairness, and comity — typically points towards declining to exercise supplemental jurisdiction over any remaining state-law claims. Kolari v. N.Y.-Presbyterian Hosp., 455 F.3d 118, 122-24 (2d Cir. 2006). Having dismissed all of the claims over which this Court has original jurisdiction,13 declining to exercise supplemental jurisdiction over the state-law claims is appropriate at this early stage in the litigation. See, e.g., Elgendy v. City of New York, No. 99 Civ. 5196, 2000 WL 1119080, at *6 (S.D.N.Y. Aug. 7, 2000) (declining to exercise supplemental jurisdiction over state-law claims after granting the defendant's motion to dismiss the federal claims). The Court therefore dismisses the plaintiff's state-law claims against the DSNY and Pouncie without prejudice. See Chen v. Major League Baseball, 6 F.Supp.3d 449, 460-61, 2014 WL 1230006, at *9 (S.D.N.Y.2014).

CONCLUSION

The Court has considered all of the arguments of the parties. To the extent not specifically addressed above, the remaining arguments are either moot or without merit. For the foregoing reasons, the DSNY's motion to dismiss the plaintiff's ADA, ADEA, and Title VII claims is granted, and all federal claims are dismissed. The plaintiff's state-law claims are dismissed without prejudice. The Clerk is directed to close Docket No. 30, to enter judgment, and to close this case.

SO ORDERED.
