On November 16, 2001, Guardsmark, Inc. indefinitely suspended its employee, security officer Carl Thomas, after he suggested in a televised interview that Guardsmark did not adequately screen its employees for prior felony convictions. Almost a year later, Thomas filed suit against Guardsmark, alleging retaliatory discharge in violation of Illinois public policy. After removing to federal district court, Guardsmark successfully moved for judgment on the pleadings pursuant to Fed. R. Civ. P. 12(c). Guardsmark argued, and the district court agreed, that Thomas was “effectively discharged” at the time he was suspended, and thus his action was barred by a six-month limitations period found in his Employment Agreement with Guardsmark. For the reasons discussed below, we reverse and remand to the district court for development of the record regarding Thomas’s employment status after Guardsmark indefinitely suspended him in November 2001.
I
In September 1998, Guardsmark hired Thomas to work as a security officer for a CITGO oil refinery in Lemont, Illinois. As a condition of his employment, Thomas signed an Employment Agreement, which detailed the terms and conditions of his employment. The Agreement specified that “[ejxcept for charges or claims filed with the Equal Employment Opportunity Commission or under any of the statutes enforced by said agency, any legal action or proceeding related to or arising out of this Agreement or the employment of Employee by Guardsmark must be brought by Employee within six months of the date the cause of action arose or it shall be time-barred.” It also provided that Tennessee law would “govern the interpretation, validity, and effect of this Agreement.” Thomas and a Guardsmark representative signed the Agreement on September 21, 1998.
In November 2001, an investigative reporter for a local news station contacted Thomas in connection with a story about regulation of the security industry in Illinois. In an on-camera interview, Thomas stated that a fellow Guardsmark security officer at the CITGO refinery had bragged about his felony record. Thomas also opined that convicted felons should not be trusted to provide security at installations that are likely terrorist targets, such as oil refineries. The story was broadcast on November 8, 2001, and eight days later, Edward Healy, Vice President and Manager of Guardsmark’s Chicago office, informed Thomas that his employment was indefinitely suspended because of his unauthorized interview with the news station. *704 Since then, Guardsmark has not compensated Thomas or allowed him to perform services for the company.
On October 31, 2002, Thomas filed a one-count complaint against Guardsmark and Healy in the Circuit Court of Cook County, alleging retaliatory discharge in violation of the public policy of the State of Illinois. Guardsmark removed to federal district court, arguing that Thomas, an Illinois citizen, had improperly joined Healy, also an Illinois citizen, and that full diversity would exist if the latter were dismissed. When Thomas filed suit, Guardsmark was a Delaware corporation with its principal place of business in Tennessee; by the time it filed its notice of removal, it had converted into a limited liability corporation, with members who are citizens of New York and Tennessee.

As a preliminary matter, we briefly address Guardsmark’s motion to strike, which asks that we disregard several pages of Thomas’s supplemental appendix that were not included in the record before the district court. These materials document his efforts to access his Guardsmark 401 (k) retirement plan following his indefinite suspension. We deny Guardsmark’s motion, on the ground that Thomas provided these materials not for evidentiary, but rather for illustrative purposes — that is, not to establish the truth of their contents, but to show that there might be a set of facts consistent with his allegations in the complaint, such that the Agreement’s six-month limitations period would not bar his claim. In any event, as the discussion that follows makes clear, we have not taken these documents into account in holding that Guardsmark cannot prevail on its motion for judgment on the pleadings.
We review
de novo
Rule 12(c) motions for judgment on the pleadings.
Midwest Gas Servs., Inc. v. Ind. Gas Co.,
Thomas presents three arguments in support of his position that his retaliatory discharge claim is not barred by the six-month limitations period provided in the Employment Agreement. First, he contends that the Agreement does “not constitute a binding and enforceable contract.” In order to evaluate this point, we must determine what body of law governs the validity of the Agreement. The Agreement itself provides that Tennessee law “governfs] the interpretation, validity, and effect of this Agreement.” In a diversity case, the federal court must apply the
*705
choice of law rules of the forum state to determine applicable substantive law.
Klaxon Co. v. Stentor Elec. Mfg. Co.,
Thomas argues that the Agreement is unenforceable both because Guardsmark did not review and approve the Agreement, as required by the Agreement itself, and because the Agreement “create[d] no obligation on Guardsmark.” Neither of these arguments is persuasive. The preamble of the Agreement says that “[t]he Agreement shall not become binding upon Guardsmark until reviewed and approved by the Compliance Control Officer in Guardsmark’s Executive Offices in Memphis, Tennessee.” Thomas asserts that “[t]here is no evidence to show that Guardsmark ever fulfilled this lone obligation,” but the record indicates otherwise. Guardsmark attached to its answer to Thomas’s complaint a document entitled, “Guardsmark: Personnel File Review,” which lists Thomas’s name and date of hire. This document is initialed by a “Selection Controller” and has a check next to the heading “APPROVED.” Thomas nonetheless insists that Guardsmark cannot rely on this document because its “purpose and authenticity ... is completely unexplained.” See
N. Ind. Gun & Outdoor Shows, Inc. v. City of South Bend,
Thomas also argues that the Agreement is invalid because “[t]here is simply nothing that Guardsmark agrees to do in exchange for the many obligations it seeks to impose on Mr. Thomas.” It is well-established that consideration consists of some detriment to the offeror, some benefit to the offeree, or some bargained-for exchange between them.
Doyle v. Holy Cross Hosp.,
Thomas next argues that, even if the Agreement is a valid contract, his claim is not barred because the six-month limitations period is unenforceable. Under the terms of the Agreement, the enforceability of this provision is governed by Tennessee law. As we have already noted, Illinois courts respect a contractual choice-of-law clause if the contract is valid, and the law chosen is not contrary to Illinois’s fundamental public policy.
Fulcrum,
Neither Guardsmark nor Thomas suggests that Tennessee law upholding contractual limitations periods is contrary to Illinois’s public policy, as both states have routinely upheld contractual provisions shortening a limitations period otherwise provided by statute. See
Taylor v. W. & S. Life Ins. Co.,
In Tennessee, “it is a well established general rule that in the absence of a prohibitory statute, a contract provision is valid which limits the time for bringing suit, if a reasonable period of time is provided, and that the general statutes of limitations are not prohibitory of such contractual provisions as between private individuals or corporations.”
State v. Evans,
We turn, then, to Thomas’s final argument: that his retaliatory discharge claim is not barred by the Agreement’s limitations period because his cause of action did not arise more than six months before he filed suit. Illinois law governs our analysis of this issue, because it relates to an aspect of the statute of limitations not addressed in the agreement. A federal court sitting in diversity must follow the statute of limitations that the state in which it is sitting would use. See
Guaranty Trust Co. v. York,
In general, Illinois courts hold that “a limitations period begins to run when facts exist that authorize one party to maintain an action against another.”
Feltmeier v. Feltmeier,
The problem with this position is that only an
actual
termination can support an employee’s retaliatory discharge claim under Illinois law. In the closely related area of discriminatory termination cases, the Tennessee Supreme Court has held that a discriminatory discharge is complete “when the plaintiff is given unequivocal notice of the employer’s termination decision, even if employment does not cease until a designated date in the future.”
Weber v. Moses,
The Illinois Supreme Court “has consistently sought to restrict the common law tort of retaliatory discharge.”
Fisher v. Lexington Health Care, Inc.,
In light of these decisions, we decline to find Thomas’s retaliatory discharge claim barred on the theory that Guardsmark’s action in November 2001 was equivalent to a discharge. Such a holding would contravene Illinois law, see
Prince v. Rescorp Realty,
Because this case comes to us on a Rule 12(c) motion for judgment on the pleadings, we lack sufficient information to determine when, if ever, Thomas’s indefinite suspension became an actual discharge. Discovery might reveal more about Guardsmark’s corporate practices with respect to indefinite suspensions, including whether such a suspension is the equivalent of a discharge because no suspended employee is in fact ever recalled. In addition, Guardsmark’s employee and insurance records and information regarding Thomas’s access to the funds in his 401(k) retirement plan might assist in clarifying Thomas’s employment status during the period between November 2001 and October 2002. While this case may ultimately prove appropriate for summary judgment, Guardsmark cannot prevail as a matter of law at this stage in the proceedings, given that a disputed question of fact remains as to whether Thomas was discharged and, if so, when he was.
Ill
As it is not beyond doubt that Thomas will be unable to prove any facts that would support his claim for relief, we Reverse the district court’s judgment for Guardsmark and Remand for proceedings consistent with this opinion.
