Affirmed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Robert Wheeler appeals the district court’s order granting Defendant’s Fed. R.Civ.P. 12(b)(6) motion and dismissing his civil action for failure to state a claim upon *351 which relief may be granted. We have reviewed the record and find no reversible error. Wheeler’s allegations fail to state a plausible claim for relief for breach by Defendant of its duty of fair representation. See Air Line Pilots Ass’n, Int’l v. O’Neill, 499 U.S. 65, 67, 111 S.Ct. 1127, 113 L.Ed.2d 51 (1991) (explaining that a union breaches its duty of fair representation “if its actions are either arbitrary, discriminatory, or in bad faith” and that union action is arbitrary “only if, in light of the factual and legal landscape at the time of the union’s actions, the union’s behavior is so far outside a wide range of reasonableness as to be irrational” (internal quotation marks and citation omitted)); Jeffreys v. Commc’ns Workers of Am., 354 F.3d 270, 275-76 (4th Cir. 2003) (explaining that the duty of fair representation “prohibits only invidious discrimination, such as discrimination based on constitutionally protected categories like race or gender, or discrimination that arises from animus or prejudice,” and that the bad faith inquiry turns on “the subjective motivation of the union’s officials”).

Accordingly, although we grant leave to proceed in forma pauperis, we affirm the district court’s order. Wheeler v. UFCW Local 27, No. 1:13-cv-00761-CCB (D.Md. Apr. 17, 2013). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

AFFIRMED.
