In November 2009, pro se plaintiff Gloria Gear, former employee of the New York City school system, filed a second amended complaint against defendants-appellees United Federation of Teachers ("UFT"), Gear's union, and the New York City Department of Education ("DOE"),
As to Gear's claims against UFT, we review de novo dismissals under subsections (b)(1) and (b)(6) of Rule 12. See Chambers v. Time Warner, Inc., 282 F.3d 147, 152 (2d Cir. 2002); Scherer v. Equitable Life Assurance Soc'y of U.S., 347 F.3d 394, 397 (2d Cir. 2003). The district court correctly dismissed Gear's claims against UFT for breach of the duty of fair representation under the National Labor Relations Act and Labor Management Relations Act because Gear was an employee of DOE, a political subdivision of a state, and those acts exclude public employees from coverage. See Ford v. D.C. 37 Union Local 1549, 579 F.3d 187, 188 (2d Cir. 2009) (per curiam) (affirming dismissal of public employee's federal duty of fair representation claim). Insofar as the district court erred by failing to construe Gear's claim of "failure to represent correctly" as raising a fair representation claim under state law, see N.Y. Civ. Serv. Law § 209-a(2)(c), we affirm the dismissal of any such claim Gear may be construed to have alleged because the court properly declined to exercise supplemental jurisdiction over Gear's state claims upon its dismissal of the federal claims. In addition, the district court correctly dismissed Gear's Title VII claims against UFT because she made only conclusory allegations and provided no factual allegations in support. See Harris v. Mills, 572 F.3d 66, 72 (2d Cir. 2009).
As to Gear's Title VII claims against DOE, we review de novo a district court's grant of summary judgment. See Miller v. Wolpoff & Abramson, L.L.P., 321 F.3d 292, 300 (2d Cir. 2003). Summary judgment is appropriate "[w]here the record taken as a whole could not lead a rational trier of fact to find for the non-moving party." Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986).
The district court correctly granted summary judgment as to Gear's claim of discriminatory suspension and termination because DOE provided evidence that its actions were based on Gear's disciplinary violations, and Gear provided no evidence—other than her own unsubstantiated denials—that this proffered legitimate justification was pretextual. See, e.g., St. Mary's Honor Ctr. v. Hicks, 509 U.S. 502, 515 (1993).
Gear's hostile environment claim also fails because, even assuming arguendo that the alleged abusive conduct was sufficiently "severe or pervasive" under Harris v. Forklift Sys., Inc., 510 U.S. 17, 21 (1993), the claim is time-barred: the alleged racist conduct occurred more than 300 days before Gear filed her Equal Employment Opportunity Commission charge. See Van Zant v. KLM Royal Dutch Airlines, 80 F.3d 708, 712 (2d Cir. 1996).
Finally, the court properly granted summary judgment as to Gear's retaliation claims because Gear failed to establish a causal connection between any protected activity and adverse employment actions. Gear's 2005 charge was too temporally remote from her 2007 termination to establish a causal connection, and her March 2007 charge was filed after she was suspended and terminated. Gear's informal complaints cannot support a retaliation claim because Gear admitted that these complaints were unrelated to any arguable Title VII violation. See Galdieri-Ambrosini v. Nat'l Realty & Dev. Corp., 136 F.3d 276, 292 (2d Cir. 1998) (explaining that "protected activity," requires a showing that the plaintiff "possessed a good faith, reasonable belief" that the conduct violated Title VII (internal quotation marks omitted)).
We have considered all of Gear's remaining arguments and find them to be without merit. Accordingly, we
