MEMORANDUM OPINION AND ORDER
Defendant General Teamsters Union, Local 673 ("Local 673") moves to dismiss  Plaintiffs' one-count complaint alleging breach of the duty of fair representation. Defendant claims that its failure to file a timely notice with Plaintiff's employer is insufficient to support Plaintiff's claim that Defendant breach its duty to fairly represent Plaintiffs. For the following reasons, Defendant's motion is denied.
According to Plaintiffs' complaint, Defendant operates as a "labor organization" under the Labor Management Relations Act of 1947 ("LMRA"). Plaintiffs are employed by UChicago Argonne, LLC ("Argonne"). Pursuant to a collective bargaining agreement ("the agreement") between Local 673 and Argonne, Local 673 is the exclusive bargaining representative of Plaintiffs in their dealings with Argonne. Plaintiff Thomas Begeske, at all times relevant to Plaintiffs' complaint, was a union steward with Local 673, responsible for interacting with the union concerning labor disputes and the filing of grievances. Local 673's business agent at all relevant times was Javier Najera. Section 17.2 of the agreement contained a two-year wage-reopener clause which stated:
Notwithstanding the preceding sentences in this Section 17.2, the Union or the Laboratory may reopen Appendix A for the purpose of negotiating basic hourly rates to be effective on March 9, 2009 and March 8, 2010. This Agreement will be reopened for such purpose only if either party notifies the other in writing at least sixty (60) calendar days prior to March 6, 2009 that it desires to reopen the Agreement. Failing receipt by either party of such written notice prior to said sixty days, this Agreement shall continue in full force and effect until its expiration date.
Local 637 was aware of this clause, as the union had negotiated the agreement with Argonne on behalf of its members.
Plaintiffs contend that Local 637 customarily reopened collective bargaining agreements containing wage reopener clauses. The agreement required Local 637 to notify Argonne on or before January 5, 2009, that it desired to reopen the agreement to negotiate wages. In late November or early December 2008, Plaintiffs allege that Begeske called Najera and reminded him that the time to give notice pursuant to the wage reopener clause would expire shortly. Najera allegedly told Begeske not to worry because a reminder would "pop up" automatically in the computer. In early January 2009, Begeske again reminded Najera of the notice date for the wage reopener clause, and Najera again told him not to worry. Despite these reminders and the common practice of reopening agreements, Local 637 failed to notify Argonne on or before January 5, that it desired to reopen the agreement and negotiate wages; instead, the union notified Argonne on January 14, nine days after the deadline.
On February 13, 2009, Argonne informed Defendant that Argonne would not reopen the agreement because Defendant had missed the deadline. On May 20, 2009, Argonne notified Defendant that it would have negotiated the wages in good faith if Defendant had timely requested to reopen the agreement. On previous occasions when Defendant and Argonne negotiated wages pursuant to a wage reopener clause, Defendant's members have received between 2.6% and 3.0% raises per year. On June 9, 2009, Argonne renegotiated its contract with SEIU, a union similar to Defendant, and SEIU's members received a raise of 2.8% to 3.4% for the 2009-2010 year.
As a result of Defendant's failure to timely file a request to reopen the agreement, Plaintiffs filed a one-count complaint against Local 637 for breach of the duty of fair representation.
II. Legal Standard on a Rule 12(b)(6) Motion
A motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6) tests the sufficiency of the complaint, not the merits of the case.See Gibson v. City of Chicago, 910 F.2d 1510, 1520 (7th Cir. 1990). To survive a Rule 12(b)(6) motion to dismiss, the complaint first must comply with Rule 8(a) by providing "a short and plain statement of the claim showing that the pleader is entitled to relief" (FED. R. CIV. P. 8(a)(2)), such that the defendant is given "fair notice of what the * * * claim is and the grounds upon which it rests." Bell Atlantic Corp. v. Twombly, 550 U.S. 544, 555 (2007) (quoting Conley v. Gibson, 355 U.S. 41, 47 (1957)). Second, the factual allegations in the complaint must be sufficient to raise the possibility of relief above the "speculative level," assuming that all of the allegations in the complaint are true. E.E.O.C. v. Concentra Health Servs., Inc., 496 F.3d 773, 776 (7th Cir. 2007) (quoting Twombly, 550 U.S. at 555). "Detailed factual allegations" are not required, but the plaintiff must allege facts that, when "accepted as true, * * * 'state a claim to relief that is plausible on its face.'" Ashcroft v. Iqbal, --- U.S. ----, ----, 129 S.Ct. 1937, 1949 (2009) (quoting Twombly, 550 U.S. at 555). "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."
Iqbal, 129 S.Ct. at 1949. "[O]nce a claim has been stated adequately, it may be supported by showing any set of facts consistent with the allegations in the complaint." Twombly, 550 U.S. at 563. The Court accepts as true all of the well-pleaded facts alleged by the plaintiff and all reasonable inferences that ...
