delivered the opinion of the Court.
This сase presents the question whether a general arbitration clause in a collective-bargaining agreement (CBA) requires an employee to use the arbitration procedure for an alleged violation of the Americans with Disabilities Act of 1990 (ADA), 104 Stat. 327,42 U. S. C. § 12101 et seq.

In 1970, petitioner Ceasar Wright began working as a longshoreman in Charleston, South Carolina. He was a member of Local 1422 of the International Longshoremen’s Association, AFL-CIO (Union), which uses a hiring hall to supply workers to several stevedore companies represented by the South Carolina Stevedores Association (SCSA). Clause 15(B) of the CBA between the Union and the SCSA provides in part as follows: “Matters under dispute which cannоt be promptly settled between the Local and an individual Employer shall, no later than 48 hours after such discussion, be referred in writing covering the entire grievance to a Port Grievance Committee ....” App. 43a. If the Port Grievance Committee, which is evenly divided between representatives of labor and management, cannot reаch an *73 agreement within five days of receiving the complaint, then the dispute must be referred to a District Grievance Committee, which is also evenly divided between the two sides. The CBA provides that a majority decision of the District Grievance Committee “shall be final and binding.” Id., at 44a. If the District Grievance Committee cannot reach a majоrity decision within 72 hours after meeting, then the committee must employ a professional arbitrator.
Clause 15(F) of the CBA provides as follows:
“The Union agrees that this Agreement is intended to cover all matters affecting wages, hours, and other terms and conditions of employment and that during the term of this Agreement the Employers will not be required to negotiate on any further matters affecting these or other subjects not specifically set forth in this Agreement. Anything not contained in this Agreement shall not be construed as being part of this Agreement. All past port practices being observed may be reduced to writing in each port.” Id., at 45a-46a.
Finally, Clause 17 of the CBA states: “It is the intention and purpose of all parties hereto that no provisiоn or part of this Agreement shall be violative of any Federal or State Law.” Id., at 47a.
Wright was also subject to the Longshore Seniority Plan, which contained its own grievance provision, reading as follows: “Any dispute concerning or arising out of the terms and/or conditions of this Agreement, or dispute involving the interpretation or application of this Agrеement, or dispute arising out of any ride adopted for its implementation, shall be referred to the Seniority Board.” Id., at 48a. The Seniority Board is equally divided between labor and management representatives. If the board reaches agreement by majority vote, then that determination is final and binding. If the board cannot resolve the disputе, then the Union and *74 the SCSA each choose a person, and this “Committee of two” makes a final determination.
On February 18, 1992, while Wright was working for respondent Stevens Shipping and Terminal Company (Stevens), he injured his right-heel and his back. He sought compensation from Stevens for permanent disability under the Longshore and Harbor Workers’ Compensation Act, 44 Stat. 1424, as amended, 33 U. S. C. § 901 et seq., and ultimately settled the claim for $250,000 and $10,000 in attorney's fees. Wright was also awarded Social Security disability benefits.
In January 1995, Wright returned to the Union hiring hall and asked to be referred for work. (At some point he obtained a written note from his doctor approving such activity.) Between January 2 and January 11, Wright worked for four stevedoring companies, none of which complained about his performance. When, however, the stevedoring companies realized that Wright had previously settled a claim for permanent disability, they informed the Union that they would not accept Wright for employment, because a person certified as permanently disabled (which they regarded Wright to be) is not qualified to perform longshore work under the CBA. The Union responded that the employers had misconstrued the CBA, suggested that the ADA entitled Wright to return to work if he could perform his duties, and asserted that refusing Wright employment would constitute a “lock-out” in violation of the CBA.
When Wright found out that the stevedoring companies would no longer accept him for employment, he contacted the Union to ask how he could get back to work. Wright claims that instead of suggesting the filing of a grievance, the Union told him to obtain counsel and file a claim under the ADA. Wright hired an attorney and eventually filed charges of discrimination with the Equal Employment Opportunity Commission (EEOC) and the South Carolina Stаte Human Affairs Commission, alleging that the stevedoring *75 companies and the SCSA had violated the ADA by refusing him work. In October 1995, Wright received a right-to-sue letter from the EEOC.
In January 1996, Wright filed a complaint against the SCSA and six individual stevedoring companies in the United States District Court for the District of South Carolina. Respondents’ answer asserted various affirmative defenses, including Wright’s failure to exhaust his remedies under the CBA and the Seniority Plan. After discovery, respondents moved for summary judgment and Wright moved for partial summary judgment with respect to some of respondents’ defenses. A Magistrate Judge recommended that the District Court dismiss the ease without prejudice because Wright had failed to pursue the grievance prоcedure provided by the CBA. The District Court adopted the report and recommendation and subsequently rejected Wright’s motion for reconsideration. The United States Court of Appeals for the Fourth Circuit affirmed, see No. 96-2850 (July 29, 1997), judgt. order reported at
In this ease, the Fourth Circuit concluded that the general arbitration provision in the CBA governing Wright’s еmployment was sufficiently broad to encompass a statutory claim arising under the ADA, and that such a provision was enforceable. The latter conclusion brings into question two lines of our case law. The first is represented by
Alexander
v.
Gardner-Denver Co.,
The second line of eases implicated here is represented by
Gilmer
v.
Interstate/Johnson Lane Corp., supra,
which held that a elaim brought under the Age Discrimination in Employment Act of 1967 (ADEA), 81 Stat. 602, as amended, 29 U. S. C. § 621
et seq.,
could be subject to compulsory arbitration pursuant to an arbitration provision in a securities registration form. Relying upon the federal policy favoring arbitration embodied in the Federal Arbitration Act (FAA), 9 U. S. C. § 1
et seq.,
we said that “statutory claims may be the subject of an arbitration agreement, enforceable pursuant to the FAA.”
There is obviously some tension between these two lines of cases. Whereas
Gardner-Denver
stated that “an employee’s
*77
rights under Title VII are not susceptible of prospective waiver,”

In asserting the existence of an agreement to arbitrate the ADA claim, respondents rely upon the presumption of arbitrability this Court has found in §301 of the Labor Management Relatiоns Act, 1947 (LMRA), 61 Stat. 156, 29 U. S. C. § 185.

v.
Enterprise

Wheel & Car Corp.,
That presumption, however, does not extend beyond the reach of the principal rationale that justifies it, which is that arbitrators are in a better position than courts
to interpret the terms of a CBA
See
AT&T Technologies, supra,
at 650;
Warrior & Gulf, supra,
at 581-582. This rationale finds support in the very text of the LMRA, which announces that “[fjinal 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) (emphasis added). The dispute in the present case, however, ultimately concerns not the application or
*79
interpretation of any CBA, but the meaning of a federal stаtute. The cause of action Wright asserts arises not out of contract, but out of the ADA, and is distinct from any right conferred by the collective-bargaining agreement. See
Gilmer, supra,
at 34;
Barrentine,
Nor is the statutory (as opposed to contractual) fоcus of the claim altered by the fact that Clause 17 of the CBA recites it to be “the intention and purpose of all parties hereto that no provision or part of this Agreement shall be violative of any Federal or State Law.” App. 47a. As we discuss below in Part IV, this does not incorporate the ADA by reference. Even if it did so, however — thereby creating a contractual right that is coextensive with the federal statutory right — the ultimate question for the arbitrator would be not what the parties have agreed to, but what federal law requires; and that is not a question which should be presumed to be included within the arbitration requirement. Application of that principle is unaffected by the fact that the CBA in this case, unlike the one in Gardner-Denver, does not expressly limit the arbitrator to interpreting and applying the contract. The presumption only extends that far, whether or not the text of the agreement is similarly limited. It may well be that ordinary textual analysis of a CBA will show that matters which go beyond the interpretation and application of contract terms arе subject to arbitration; but they will not be presumed to be so.
IV
Not only is petitioner’s statutory claim not subject to a presumption of arbitrability; we think any CBA requirement to arbitrate it must be particularly dear. In
Metropolitan Edison Co.
v.
NLRB,
We think the same standard applicable to a union-negotiated waiver of employees’ statutory right to a judicial forum for claims of employment discrimination. Although that is not a substantive right, see
Gilmer,
Respondents rely upon Clause 15(F) of the CBA, which states that “this Agreement is intended to cover all matters affecting wages, hours, and other terms and conditions of employment.” App. 45a-46a. But even if this could, in isolation, be cоnsidered a clear and unmistakable incorporation of employment-discrimination laws (which is doubtful), it is surely deprived of that effect by the provision, later in the same paragraph, that “[ajnything not contained in this Agreement shall not be construed as being part of this Agreement.” Id., at 46a. Respondents also rely upon Clause 17 of the CBA, which statеs that “[i]t is the intention and purpose of all parties hereto that no provision or part of this Agreement shall be violative of any Federal or State Law.” Id., at 47a. They argue that this requires the arbitrator to “apply legal definitions derived from the ADA” in determining whether Wright is “qualified” for employment within the meaning of the CBA. Brief for Respondents 39. Perhaрs so, but that is not the same as making compliance with the ADA a contractual commitment that would be subject to the arbitration clause. This becomes crystal clear when one contrasts Clause 17 with the provision of the CBA which states that “[t]he requirements of the Occupations [sic] Safety and Health Administration shall be binding on both Parties.” App. 46a. (Under respondents’ interpretation of Clause 17, this OSHA provision would be superfluous.) Clause 17 seems to us nothing more than a recitation of the canon of construction which would in any event have been applied to the CBA — that an agreement should be interpreted in such fashion as to preserve, rather than destroy, its validity (ut res magis valeat quarn pereat).
Finally, we do not find a сlear and unmistakable waiver in the Longshore Seniority Plan. Like the CBA itself, the plan contains no antidiscrimination provision; and it specifi- *82 eally limits its grievance procedure to disputes related to the agreement. 2
* * *
We hold that the collective-bargaining agreement in this case does not contain a clear and unmistakable waiver of the covered employees’ rights to a judicial forum for federal claims of employment discrimination. We do not reach the question whether such a waiver would be enforceable. The judgment of the Fourth Circuit is vacated, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
