OPINION
Plaintiff-Appellant Titan Tire Corporation of Bryan appeals from the district court’s summary judgment in favor of Defendant-Appellee United Steelworkers of America, Local 890L. Titan challenges the district court’s refusal to vacate a labor arbitration award finding that Titan lacked just cause to terminate Linda Tracy, a Titan employee and Union member. For the following reasons, we AFFIRM the judgment of the district court.
I. BACKGROUND
On March 8, 2008, Linda Tracy injured her wrist as a result of an equipment malfunction while performing her job at Titan. She was sent to the hospital for treatment. While there, she was tested for drugs in accordance with the drug policy originally negotiated between the Union and Titan’s predecessor, Continental General Tire, Inc., and later adopted by Titan in a letter of understanding attached to the parties’ collective bargaining agreement (“CBA”). Tracy tested positive for marijuana use, and was subsequently terminated by Titan based exclusively on the positive test result.
The Union grieved the termination, arguing that it was excessive and unjust. The parties submitted the dispute to arbitration pursuant to the CBA. Before the arbitrator, the Union argued that there was no just cause for the termination because neither Titan nor Continental had provided its employees, including Tracy, advance notice of the drug policy and the consequences for testing positive, as was required under the policy. Titan, on the other hand, claimed that there was just cause for Tracy’s termination given language in the drug policy stating that individuals who test positive are “subject to termination,” which Titan interpreted as providing for automatic termination.
After conducting an evidentiary hearing, the arbitrator sustained the Union’s grievance on October 16, 2008. The arbitrator concluded that Titan lacked just cause to terminate Tracy because Tracy — a nine-year and otherwise “satisfactory” employee — was not given adequate advance notice of the drug policy and the consequences for violating it as required by Section V of the policy. Although the arbitrator found Titan’s interpretation of the “subject to termination” language in the drug policy to be “intellectually inviting,” he ultimately rejected Titan’s argument that “subject to termination” means automatic termination. His conclusion was partially based on evidence that the pertinent language was a compromise between Continental and the Union. During negotiations, Continental apparently proposed the language “will be terminated,” but Union negotiators successfully had it changed to “subject to termination,” so that it would not provide for automatic termination. The arbitrator concluded that though Titan was unaware that “subject to termination” was a compromise, it still adopted bargaining intent when it accepted the existing drug program. Find *371 ing that Tracy’s summary discharge did not adhere to just cause criteria, the arbitrator modified her termination to a ninety-day suspension and reinstated her to work with backpay. He also authorized Titan to subject Tracy to unannounced random drug testing for one year after her reinstatement.
On December 19, 2008, Titan filed this action in the Northern District of Ohio, asking the district court to vacate the arbitrator’s award. The parties filed cross motions for summary judgment and the district court held a hearing on the matter. Titan’s primary contention before the district court was that the arbitrator violated Article 19.04 of the CBA by relying on the negotiating history between Continental and the Union in construing the phrase “subject to termination.” Among other things, Article 19.04 provides that Titan is not bound by any “oral representations with any previous employer regarding ... the Agreements .:. or past practices ... unless specifically adopted by [Titan] in writing.” It also requires the Union to give Titan thirty days advance notice before introducing in an arbitration proceeding evidence of the negotiating parties’ intent at the bargaining table.
On October 26, 2009, the district court granted the Union’s motion and denied Titan’s motion. Recognizing that a court must enforce an arbitration award if the arbitrator even arguably construed or applied the contract, the court affirmed the arbitrator’s award because it was “indisputable that the arbitrator was construing and applying” the particular provisions of the CBA “relevant to the just cause standard, as well as the ‘subject to termination’ language that is the subject of the parties’ dispute.” Furthermore, the court concluded that even if citing the negotiating history between Continental and the Union was error, such error was harmless, because the language of the CBA alone could justify the arbitrator’s conclusion. According to the district court, the plain meaning of “subject to termination” indicates that permanent discharge is “an option” for employees who test positive for drugs, but it is not automatic. Titan filed this timely appeal.
II. ANALYSIS
A. Standard of Review
“This Court reviews a district court’s grant of summary judgment in a labor arbitration dispute
de novo.” Totes Isotoner Corp. v. Int’l Chem. Workers Union Council/UFCW Local 664C,
B. Limited Judicial Review of Labor-Arbitration Decisions
Federal labor arbitration ease law is shaped largely by the strong congressional policy encouraging the resolution of labor disputes through arbitration procedures selected by the parties. Section 203(d) of the Labor Management Relations Act provides, “[f]inal adjustment by a method agreed upon by the parties is declared to be the desirable method for settlement of grievance disputes arising over the application or interpretation of an existing collective-bargaining agreement.” 29 U.S.C. § 173(d). The seminal Supreme Court instruction on this national policy is found in the Steelworkers Trilogy, 1 three cases si *372 multaneously decided in 1960. Their key lesson is that the judiciary shall defer to the method selected by the parties to settle their differences, usually a grievance procedure culminating in final and binding arbitration.
Such judicial deference is grounded in the unique realities of workplace governance through collective bargaining agreements. While commercial contracts deem resort to courts or arbitration as a “breakdown in the working relationship of the parties,”
the grievance machinery under a collective bargaining agreement is at the very heart of the system of industrial self-government. Arbitration is the means of solving the unforeseeable by molding a system of private law for all the problems which may arise and to provide for their solution in a way which will generally accord with the variant needs and desires of the parties.

[1] Did the arbitrator act outside his authority by resolving a dispute not committed to arbitration? [2] Did the arbitrator commit fraud, have a conflict of interest or otherwise act dishonestly in issuing the award? [3] And in resolving any legal or factual disputes in the case, was the arbitrator arguably construing or applying the contract?
Id. (internal quotation marks omitted). If the arbitrator “does not offend any of these requirements, the request for judicial intervention should be resisted even though the arbitrator made serious, improvident or silly errors in resolving the merits of the dispute.” Id. (internal quotation marks omitted).
C. Arbitrator’s Construction of the Titan-Union CBA
Titan and the- Union jointly submitted the just-cause question to the arbitrator pursuant to the CBA, and Titan does not allege that the arbitrator acted with fraud, a conflict of interest, or dishonesty in issuing his decision. Consequently, the first and second questions posed by Michigan Family Resources are not implicated in this appeal. The only issue is whether, in making the just-cause determination, the arbitrator arguably construed or applied the contract. Id. Titán primarily contends that the arbitrator did not do so because, in construing the “subject to termination” clause, he considered evidence of bargaining history in violation of Article 19.04 of the CBA. 3
Titan’s argument is foreclosed by this Court’s

At issue in
Michigan Family Resources
was an arbitrator’s construction of ambiguous language contained in a collective bargaining agreement. In construing the language in favor of the union, the arbitrator considered evidence of past practices between the parties, despite a provision in the agreement prohibiting the use of such evidence to bind the parties.
This Court acknowledged, however, that “[a]n interpretation of a contract ... could be so untethered to the terms of the agreement ... that it would cast doubt on whether the arbitrator indeed was engaged in interpretation.” Id. at 753 (internal quotation marks omitted). But we rejected the argument that the arbitrator’s interpretative errors, including its reliance on evidence of past practices arguably in violation of the parties’ CBA, satisfied this standard. The ambiguity in the contract “permitted, indeed required, the arbitrator to engage in construction of the agreement, which is all [the Court is] asked to determine.” Id. at 755. “[W]e review outcomes, not opinions, while performing the exceedingly deferential task of considering whether to vacate an arbitration award.” Id. The fact that the arbitrator may have chosen the “wrong path in justifying the award” does not give us a “warrant to vacate it.” Id.
In the present case, the arbitrator interpreted the drug policy to require Titan to warn employees about discipline for positive drag tests. Section V of the policy specifically requires that employees be informed of the “[consequences for ... a positive controlled substances test.” In light of Titan’s failure to provide its employees such notice, the arbitrator concluded that Titan lacked just cause to terminate Tracy based entirely on her positive drug test. There is no indication in the arbitrator’s twenty-four-page opinion reaching this conclusion that he “was doing anything other than trying to reach a good-faith interpretation of the contract.”
Mich. Family Res.,
Moreover, it cannot be “said that the arbitrator’s decision on the merits was so untethered from the agreement that it casts doubt on whether he was engaged in interpretation, as opposed to the implementation of his ‘own brand of industrial justice.’ ”
Id.
(quoting
Enter. Wheel & Car Corp.,
Titan challenges the arbitrator’s reliance on evidence of bargaining history between the Union and Continental in construing the “subject to termination” language. It contends that Article 19.04 of the CBA prohibited the arbitrator from relying on such evidence. It is questionable whether Article 19.04, which concerns oral representations and intent evidence, even applies to the exchange of proposed written contract provisions, the bargaining-history evidence relied upon by the arbitrator. But even assuming that it does, such an error would not establish that the arbitrator’s decision “was so untethered from the agreement that it casts doubt on whether he was engaged in interpretation.”

As we held in

the fact that the arbitrator may have erred by choosing “the wrong path in justifying the award ... does not give us a warrant to vacate it.”

III. CONCLUSION
For the foregoing reasons, we AFFIRM the district court’s grant of summary judgment for the Union.

. Nor can the judiciary deliver the speedy resolution of disputes envisioned by the grievance procedure, particularly in light of the overwhelming number of grievances processed under CBAs.
. We find no record of Titan presenting its Article 19.04 argument to the arbitrator. In fact, the arbitrator expressly found that Titan neither challenged nor refuted the bargaining-history evidence.
