This is аn appeal from summary judgment against workers claiming that they had been wrongfully discharged by their employer and inadequately represented by their union. The district court determined that all claims against the defendants were either time barred or preempted by Section 301 of the Labor Management Relations Act, 29 U.S.C. sec.l85(a). We now affirm the district court’s decision.
Background
The plаintiffs, Bryan Chappie, Robert Hughes, Danny Wimbleduff and Paul Miller, were employed by National Starch and Chemical Company (“National Starch”) in its Indianapolis plant. In the spring of 1995, National Starch instituted an undercover investigation in response to allegations of illegal drug use by its employees. The investigation identified twenty-one employees, including the plaintiffs,, as either users or dealers of illegal substances. On November 15, 1995 the company discharged the plaintiffs and ten others.
Claiming that the firings were improper, the plaintiffs submitted their grievances to binding arbitration pursuant to the collective bargaining agreement then in effect between National Starch and plaintiffs’ union, Local 706 of the Oil Chemical and Atomic Workers International (“Local 706”). In additiоn to the arbitration procedure, the bargaining agreement contained a management rights clause reserving to National Starch the right to discharge employees for cause and to manage the plant in accordance with the terms of the agreement and in a manner consistent with state and federal law.
Local 706 appointed attorney Robеrt Rifkin to represent the discharged employees in the arbitration procedure. On February 15, 1996, Rifkin wrote to National Starch’s attorney, Hudnall A. Pfeiffer, asserting that the company had missed a reply deadline set out in the arbitration procedures. Rifkin indicated that the union considered this a default entitling the discharged workers to immediate reinstatement with full back pay and benefits. The following day, Pfeiffer faxed a letter to Rifkin explaining that the union’s Unit Chairman Willie Williams and Chief Steward Bob Westerfield had granted National Starch an oral extension of time to respond, something the Local 706 had routinely done in the past. The plaintiffs maintain, however, that no extension was ever granted and that the union should have insisted on reinstatement. The events surrounding Rifkin’s letter form the basis of the plaintiffs’ federal claims against the union and National Starch.
In September, 1997, the four plaintiffs filed related suits against Local 706 for failure to represent their interests and against National Starch for breach of the collective bargaining agreement, wrongful termination and intentional infliction of emotional distress.
On June 25, 1998, Judge Hamilton granted summary judgment
Discussion
Time Barred Claims
Summary judgment is only appropriate if, “there is no genuine issue as to any material fact and ... the moving party is entitled to judgment as a matter of law.” Fed. R.CrvP. 56(c); Salima v. Scherwood South, Inc.,
The district court correctly held that the plaintiffs’ failure to reprеsent and breach of collective bargaining claims had not been filed within the limitations period. Both were brought pursuant to Section 301 of the LMRA, and are therefore subject to its six month statute of limitations. See DelCostello v. International Brotherhood of Teamsters,
Equitable Tolling
The plaintiffs first argue that their late filing should be excused because they were unable to discover essential evidence necessary to establishing their claim until the limitations period had expired. Cada v. Baxter Healthcare Corp.,
The plaintiffs argue that because they did not actually obtain a copy of the Rifkin letter until August 1997, after the statute of limitations expired, their claims should be tolled. We are not persuaded by this argument for two reasons. First, the plaintiffs fail to explain why the letter was essential to bringing the claim. They admitted both in district court and at oral argument before this court that they were aware of Rifkin’s letter by at least March or April of 1997, months before the limitations period for Chappie and Miller had expired. This should hаve been enough to put the plaintiffs on notice that they may have been wronged in the manner they now allege. As this court has emphasized, the tolling inquiry asks only whether the plaintiff was unable to learn of the possibility of its claim within the limitations period; it does not ask whether the plaintiff was unable to obtain solid proof.

Second, even if the information contained in the letter was not known to the plaintiffs prior to August 1997 (and assuming it was neсessary to bring suit), the plaintiffs have still failed to demonstrate diligence in attempting to obtain the information , during the limitations period. As the district court correctly concluded, aside from their assertions, the plaintiffs point to no record evidence on which a jury could reasonably base a finding that they pursued vital information concerning the claim but were unable to file it in a timely manner. See McCool v. Strata Oil Co.,
Equitable Estoppel
The plaintiffs’ second argument relies on the doctrine of equitable estoppel, sometimes referred to as fraudulent concealment. Under this doctrine, a defendant who conceals vital information about the existence of a plaintiffs claim or makes representations to the plaintiff causing it to delay bringing the claim, сan be es-topped from relying on the statute of limitations as a defense. Thelen v. Marc’s Big Boy Corp.,
As with equitable tolling, the plaintiffs have failed to demonstrate a genuine issue of material fact concerning the applicability of equitable estoppel. First, the plaintiffs have not shown that the defendants took any affirmative steps to conceal their causes of action beyond those which form the basis of the failure to represent and breach of collective bargaining claims. Cada,
Because the plaintiffs’ suit was filed after the limitations period applicable to Section 301 had expired, and because neither the tolling nor estoppel theories prevent its operation in this case, we hold that the court correctly granted summary judgment in favor of the defendants on both federal claims.
Preemption of State Law Claims
The plaintiffs filed state law claims against National Starch for wrongful discharge and intentional infliction of emotional distress. These claims are based on the same facts which underlie their claim for breach of the collective bargaining agreеment against the company. ' The plaintiffs allege that they were fired without cause and that the drug testing policy they were subjected to violated their privacy rights. The district court dismissed the plaintiffs’ state law claims holding that both were preempted by Section 301 because the resolution of each would depend upon the court’s interpretation of the collective bargaining agreement. See Avco v. Aero Lodge No. 735, Int’l Ass’n of Ma
We do not agree with the plaintiffs’ suggestion. Whether the plaintiffs were wrongfully discharged or not depends on whether the company acted properly in setting up the drug investigation and had sufficient cause to fire the plaintiffs. The answers tо these questions would require a court to decide if the employer wás acting within the scope of the management rights clause of the collective bargaining agreement. See Amoco Petroleum Additives Co.
Conclusion
We agree with the district court that the plaintiffs’ federal claims are time barred and their state law claims are preempted by Section 301. We therefore Affirm that court’s decision.
Notes
.The wrongful discharge and intentional infliction of emotional distress claims were originally filed in Indiana state court. National Starch then had them removed to federal court. The district court held that federal jurisdiction was supported by diversity, and therefore found it unnecessary to decide whether the court also had federal question jurisdiction under Section 301 and the doctrine of complete preemption. See Smith v. Colgate-Palmolive Co.,
. The court treated the defendants' motion as one for summary judgment because it was supported by affidavits, and the plaintiffs were pеrmitted to respond with affidavits of their own. See Fed.R.Civ.P. 12(c) & (d); Hentosh v. Herman M. Finch University of Health Sciences,
. In their brief, the plaintiffs argue at length that summary judgment was improper here because a genuine issue of material fact exists as to whether the union had actually granted National Starch an extension prior to Rifkin's
. The accrual date is not the day on which they were actually injured (their discharge date, earlier than the accrual date) nor the day they obtained what they consider to be their smoking gun evidence — a copy of the letter written by Rifkin (later than the accrual date). Instead it is the date on which the plaintiffs should reasonably have been aware that they had been wronged, because the termination became final. See DelCostello,
. The plaintiffs do not allege, for instance, that they sought a copy of the Rifkin letter and were refused, or ever asked about the deadline issue once they knew about it. Instead, they merely allege that they may have inquired from time to time about the status of their claims and were never told about the deadline issue.
