G. R. SMITH, Magistrate Judge.
Pro se plaintiff Faustin Kidibu brought this employment discrimination case against his ex-employer, The Fresh Market, Inc. (TFM). Doc. 1-1 at 2. He alleges that TFM "wrongfully terminated his employment effective August 14, 2012 on the ground that he purported[ly] applied for Family Medical Leave of Absence (FMLA)[,] which he never did." Id. at 3. Moving to dismiss, TFM cites as a litigation bar the arbitration agreement Kidibu signed upon his employment. Doc. 5-1; see also doc. 5-2 at 4. TFM's motion thus relies on that agreement, even though it is not part of the parties' pleadings. But it is attached to TFM's motion and is integral to the parties' contract,
Id.
FTM says Kidibu did not arbitrate his FMLA claim, which does not involve "worker's compensation and unemployment compensation claims." Doc. 5-1 at 5. In substance, Kidibu agrees. He insists that the FTM "and Management refused to discuss or talk with [p]laintiff when they know that there was an Arbitration Agreement between Employer and Employee. Plaintiff, Faustin Kidibu, contacted TFM by certified mails, by phone calls and in person in the store, but nobody agreed to talk with Plaintiff (Faustin Kidibu)." Doc 7 at 1.
Plaintiff's factual response is unsworn and otherwise not subject to a perjury-penalty declaration under 28 U.S.C. § 1746. Ordinarily, then, such "briefing assertions" cannot be considered as facts to support a court ruling. But his response may be construed as a judicial admission that the arbitration agreement exists and applies to him. See McCorvey v. United States, 2014 WL 4594475 at *9 (S.D. Ala. Sept. 11. 2014) (collecting judicial admission cases). So viewed, the Court concludes that Kibidu wants to arbitrate, otherwise presents no "gateway" matters,
Sampson v. Washington Mut. Bank, 453 F. App'x 863, 866 (11th Cir. 2011); see also Hoffman-Pugh v. Ramsey, 312 F.3d 1222, 1225 (11th Cir. 2002) (holding, in a libel case, that the entire allegedly defamatory book "was properly before the court on the motion to dismiss," even though it had not been attached to the complaint, "because [the plaintiff] referred to it in her complaint and it [was] central to her claims"), quoted in FindWhat Investor Group v. FindWhat.com, 658 F.3d 1282, 1297 n. 15 (11th Cir. 2011). Here plaintiff does not dispute the existence of the arbitration agreement and that it forms part of the core relationship between the parties. So, it is properly considered under Rule 12(b)(6).
