opinion: Mr. Justice Brennan
  delivered the opinion of the Court.
  In this case we re-examine the holding of Sinclair Refining Co. v. Atkinson, 370 U. S. 195 (1962), that the anti-injunction provisions of the Norris-LaGuardia Act preclude a federal district court from enjoining a strike in breach of a no-strike obligation under a collective-bargaining agreement, even though that agreement contains provisions, enforceable under § 301 (a) of the Labor Management Relations Act, 1947, for binding arbitration of the grievance dispute concerning which the strike was called. The Court of Appeals for the Ninth Circuit, considering itself bound by Sinclair, reversed the grant by the District Court for the Central District of California of petitioner’s prayer for injunctive relief. 416 F. 2d 368 (1969). We granted certiorari. 396 U. S. 1000 (1970). Having concluded that Sinclair was erroneously decided and that subsequent events have undermined its continuing validity, we overrule that decision and reverse the judgment of the Court of Appeals.
  I
  In February 1969, at the time of the incidents that produced this litigation, petitioner and respondent were parties to a collective-bargaining agreement which provided, inter alia, that all controversies concerning its interpretation or application should be resolved by adjustment and arbitration procedures set forth therein and that, during the life of the contract, there should be “no cessation or stoppage of work, lock-out, picketing or boycotts . The dispute arose when petitioner’s frozen foods supervisor and certain members of his crew who were not members of the bargaining unit began to rearrange merchandise in the frozen food cases of one of petitioner’s supermarkets. A union representative insisted that the food cases be stripped of all merchandise and be restocked by union personnel. When petitioner did not accede to the union’s demand, a strike was called and the union began to picket petitioner’s establishment. Thereupon petitioner demanded that the union cease the work stoppage and picketing and sought to invoke the grievance and arbitration procedures specified in the contract.
  The following day, since the strike had not been terminated, petitioner filed a complaint in California Superior Court seeking a temporary restraining order, a preliminary and permanent injunction, and specific performance of the contractual arbitration provision. The state court issued a temporary restraining order forbidding continuation of the strike and also an order to show cause why a preliminary injunction should not be granted. Shortly thereafter, the union removed the case to the Federal District Court and there made a motion to quash the state court’s temporary restraining order. In opposition, petitioner moved for an order compelling arbitration and enjoining continuation of the strike. Concluding that the dispute was subject to arbitration under the collective-bargaining agreement and that the strike was in violation of the contract, the District Court ordered the parties to arbitrate the underlying dispute and simultaneously enjoined the strike, all picketing in the vicinity of petitioner’s supermarket, and any attempts by the union to induce the employees to strike or to refuse to perform their services.
  II
  At the outset, we are met with respondent’s contention that Sinclair ought not to be disturbed because the decision turned on a question of statutory construction which Congress can alter at any time. Since Congress has not modified our conclusions in Sinclair, even though it has been urged to do so, respondent argues that principles of stare decisis should govern the present case.
  We do not agree that the doctrine of stare decisis bars a re-examination of Sinclair in the circumstances of this case. We fully recognize that important policy considerations militate in favor of continuity and predictability in the law. Nevertheless, as Mr. Justice Frankfurter wrote for the Court, “[Sitare decisis is a principle of policy and not a mechanical formula of adherence to the latest decision, however recent and questionable, when such adherence involves collision with a prior doctrine more embracing in its scope, intrinsically sounder, and verified by experience.” Helvering v. Hallock, 309 U. S. 106, 119 (1940). See Swift & Co. v. Wickham, 382 U. S. 111, 116 (1965). It is precisely because Sinclair stands as a significant departure from our otherwise consistent emphasis upon the congressional policy to promote the peaceful settlement of labor disputes through arbitration and our efforts to accommodate and harmonize this policy with those underlying the anti-injunction provisions of the Norris-LaGuardia Act that we believe Sinclair should be reconsidered. Furthermore, in light of developments subsequent to Sinclair, in particular our decision in Avco Corp. v. Aero Lodge 735, 390 U. S. 557 (1968), it has become clear that the Sinclair decision does not further but rather frustrates realization of an important goal of our national labor policy.
  Nor can we agree that conclusive weight should be accorded to the failure of Congress to respond to Sinclair on the theory that congressional silence should be interpreted as acceptance of the decision. The Court has cautioned that “[i]t is at best treacherous to find in congressional silence alone the adoption of a controlling rule of law.” Girouard v. United States, 328 U. S. 61, 69 (1946). Therefore, in the absence of any persuasive circumstances evidencing a clear design that congressional inaction be taken as acceptance of Sinclair, the mere silence of Congress is not a sufficient reason for refusing to reconsider the decision. Helvering v. Hallock, supra, at 119-120.
  Ill
  From the time Textile Workers Union v. Lincoln Mills, 353 U. S. 448 (1957), was decided, we have frequently found it necessary to consider various substantive and procedural aspects of federal labor contract law and questions concerning its application in both state and federal courts. Lincoln Mills held generally that “the substantive law to apply in suits under § 301 (a) is federal law, which the courts must fashion from the policy of our national labor laws,” 353 U. S., at 456, and more specifically that a union can obtain specific performance of an employer’s promise to arbitrate grievances. We rejected the contention that the anti-injunction proscriptions of the Norris-LaGuardia Act prohibited this type of relief, noting that a refusal to arbitrate was not “part and parcel of the abuses against which the Act was aimed,” id., at 458, and that the Act itself manifests a policy determination that arbitration should be encouraged. See 29 U. S. C. § 108. Subsequently in the Steelworkers Trilogy we emphasized the importance of arbitration as an instrument of federal policy for resolving disputes between labor and management and cautioned the lower courts against usurping the functions of the arbitrator.
  Serious questions remained, however, concerning the role that state courts were to play in suits involving collective-bargaining agreements. Confronted with some of these problems in Charles Dowd Box Co. v. Courtney, 368 U. S. 502 (1962), we held that Congress clearly intended not to disturb the pre-existing jurisdiction of the state courts over suits for violations of collective-bargaining agreements. We noted that the
  “clear implication of the entire record of the congressional debates in both 1946 and 1947 is that the purpose of conferring jurisdiction upon the federal district courts was not to displace, but to supplement, the thoroughly considered jurisdiction of the courts of the various States over contracts made by labor organizations.” Id., at 511.
  Shortly after the decision in Dowd Box, we sustained, in Teamsters Local 174 v. Lucas Flour Co., 369 U. S. 95 (1962), an award of damages by a state court to an employer for a breach by the union of a no-strike provision in its contract.. While emphasizing that “in enacting § 301 Congress intended doctrines of federal labor law uniformly to prevail over inconsistent local rules,” id., at 104, we did not consider the applicability of the Norris-LaGuardia Act to state court proceedings because the employer’s prayer for relief sought only damages and not specific performance of a no-strike obligation.
  Subsequent to the decision in Sinclair, we held in Avco Corp. v. Aero Lodge 735, supra, that § 301 (a) suits initially brought in state courts may be removed to the designated federal forum under the federal question removal jurisdiction delineated in 28 U. S. C. § 1441. In so holding, however, the Court expressly left open the questions whether state courts are bound by the anti-injunction proscriptions of the Norris-LaGuardia Act and whether federal courts, after removal of a § 301 (a) action, are required to dissolve any injunctive relief previously granted by the state courts. See generally General Electric Co. v. Local Union 191, 413 F. 2d 964 (C. A. 5th Cir. 1969) (dissolution of state injunction required). Three Justices who concurred expressed the view that Sinclair should be reconsidered “upon an appropriate future occasion.” 390 U. S., at 562 (Stewart, J., concurring).
  The decision in Avco, viewed in the context of Lincoln Mills and its progeny, has produced an anomalous situation which, in our view, makes urgent the reconsideration of Sinclair. The principal practical effect of Avco and Sinclair taken together is nothing less than to oust state courts of jurisdiction in § 301 (a) suits where injunc-tive relief is sought for breach of a no-strike obligation. Union defendants can, as a matter of course, obtain removal to a federal court, and there is obviously a compelling incentive for them to do so in order to gain the advantage of the strictures upon injunctive relief which Sinclair imposes on federal courts. The sanctioning of this practice, however, is wholly inconsistent with our conclusion in Dowd Box that the congressional purpose embodied in § 301 (a) was to supplement, and not to encroach upon, the pre-existing jurisdiction of the state courts. It is ironic indeed that the very provision that Congress clearly intended to provide additional remedies for breach of collective-bargaining agreements has been employed to displace previously existing state remedies. We are not at liberty thus to depart from the clearly expressed congressional policy to the contrary.
  On the other hand, to the extent that widely disparate remedies theoretically remain available in state, as opposed to federal, courts, the federal policy of labor law uniformity elaborated in Lucas Flour Co., is seriously offended. This policy, of course, could hardly require, as a practical matter, that labor law be administered identically in all courts, for undoubtedly a certain diversity exists among the state and federal systems in matters of procedural and remedial detail, a fact that Congress evidently took into account in deciding not to disturb the traditional jurisdiction of the States. The injunction, however, is so important a remedial device, particularly in the arbitration context, that its availability or nonavailability in various courts will not only produce rampant forum shopping and maneuvering from one court to another but will also greatly frustrate any relative uniformity in the enforcement of arbitration agreements.
  Furthermore, the existing scheme, with the injunction remedy technically available in the state courts but rendered inefficacious by the removal device, assigns to removal proceedings a totally unintended function. While the underlying purposes of Congress in providing for federal question removal jurisdiction remain somewhat obscure, there has never been a serious contention that Congress intended that the removal mechanism be utilized to foreclose completely remedies otherwise available in the state courts. Although federal question removal jurisdiction may well have been intended to provide a forum for the protection of federal rights where such protection was deemed necessary or to encourage the development of expertise by the federal courts in the interpretation of federal law, there is no indication that Congress intended by the removal mechanism to effect a wholesale dislocation in the allocation of judicial business between the state and federal courts. Cf. City of Greenwood v. Peacock, 384 U. S. 808 (1966).
  It is undoubtedly true that each of the foregoing objections to Sinclair-Avco could be remedied either by overruling Sinclair or by extending that decision to the States. While some commentators have suggested that the solution to the present unsatisfactory situation does lie in the extension of the Sinclair prohibition to state court proceedings, we agree with Chief Justice Traynor of the California Supreme Court that “whether or not Congress could deprive state courts of the power to give such [injunctive] remedies when enforcing collective bargaining agreements, it has not attempted to do so either in the Norris-LaGuardia Act or section 301.” McCarroll v. Los Angeles County Dist. Council of Carpenters, 49 Cal. 2d 45, 63, 315 P. 2d 322, 332 (1957), cert. denied, 355 U. S. 932 (1958). See, e. g., American Dredging Co. v. Marine Local 25, 338 F. 2d 837 (C. A. 3d Cir. 1964), cert. denied, 380 U. S. 935 (1965); Shaw Electric Co. v. I. B. E. W., 418 Pa. 1, 208 A. 2d 769 (1965).
  An additional reason for not resolving the existing dilemma by extending Sinclair to the States is the devastating implications for the enforceability of arbitration agreements and their accompanying no-strike obligations if equitable remedies were not available. As we have previously indicated, a no-strike obligation, express or implied, is the quid pro quo for an undertaking by the employer to submit grievance disputes to the process of arbitration. See Textile Workers Union v. Lincoln Mills, supra, at 455. Any incentive for employers to enter into such an arrangement is necessarily dissipated if the principal and most expeditious method by which the no-strike obligation can be enforced is eliminated. While it is of course true, as respondent contends, that other avenues of redress, such as an action for damages, would remain open to an aggrieved employer, an award of damages after a dispute has been settled is no substitute for an immediate halt to an illegal strike. Furthermore, an action for damages prosecuted during or after a labor dispute would only tend to aggravate industrial strife and delay an early resolution of the difficulties between employer and union.
  Even if management is not encouraged by the unavailability of the injunction remedy to resist arbitration agreements, the fact remains that the effectiveness of such agreements would be greatly reduced if injunctive relief were withheld. Indeed, the very purpose of arbitration procedures is to provide a mechanism for the expeditious settlement of industrial disputes without resort to strikes, lockouts, or other self-help measures. This basic purpose is obviously largely undercut if there is no immediate, effective remedy for those very tactics that arbitration is designed to obviate. Thus, because Sinclair, in the aftermath of Avco, casts serious doubt upon the effective enforcement of a vital element of stable labor-management relations — arbitration agreements with their attendant no-strike obligations — we conclude that Sinclair does not make a viable contribution to federal labor policy.
  IV
  We have also determined that the dissenting opinion in Sinclair states the correct principles concerning the accommodation necessary between the seemingly absolute terms of the Norris-LaGuardia Act and the policy considerations underlying § 301 (a). 370 U. S., at 215. Although we need not repeat all that was there said, a few points should be emphasized at this time.
  The literal terms of § 4 of the Norris-LaGuardia Act must be accommodated to the subsequently enacted provisions of § 301 (a) of the Labor Management Relations Act and the purposes of arbitration. Statutory interpretation requires more than concentration upon isolated words; rather, consideration must be given to the total corpus of pertinent law and the policies that inspired ostensibly inconsistent provisions. See Richards v. United States, 369 U. S. 1, 11 (1962); Mastro Plastics Corp. v. NLRB, 350 U. S. 270, 285 (1956); United States v. Hutcheson, 312 U. S. 219, 235 (1941).
  The Norris-LaGuardia Act was responsive to a situation totally different from that which exists today. In the early part of this century, the federal courts generally were regarded as allies of management in its attempt to prevent the organization and strengthening of labor unions; and in this industrial struggle the injunction became a potent weapon that was wielded against the activities of labor groups. The result was a large number of sweeping decrees, often issued ex parte, drawn on an ad hoc basis without regard to any systematic elaboration of national labor policy. See Drivers’ Union v. Lake Valley Co., 311 U. S. 91, 102 (1940).
  In 1932 Congress attempted to bring some order out of the industrial chaos that had developed and to correct the abuses that had resulted from the interjection 6f the federal judiciary into union-management disputes on the behalf of management. See declaration of public policy, Norris-LaGuardia Act, § 2, 47 Stat. 70. Congress, therefore, determined initially to limit severely the power of the federal courts to issue injunctions “in any case involving or growing out of any labor dispute . . . § 4, 47 Stat. 70. Even as initially enacted, however, the prohibition against federal injunctions was by no means absolute. See Norris-LaGuardia Act, §§ 7, 8, 9, 47 Stat. 71, 72. Shortly thereafter Congress passed the Wagner Act, designed to curb various management activities that tended to discourage employee participation in collective action.
  As labor organizations grew in strength and developed toward maturity, congressional emphasis shifted from protection of the nascent labor movement to the encouragement of collective bargaining and to administrative techniques for the peaceful resolution of industrial disputes. This shift in emphasis was accomplished, however, without extensive revision of many of the older enactments, including the anti-injunction section of the Norris-LaGuardia Act. Thus it became the task of the courts to accommodate, to reconcile the older statutes with the more recent ones.
  A leading example of this accommodation process is Brotherhood of Railroad Trainmen v. Chicago River & Ind. R. Co., 353 U. S. 30 (1957). There we were confronted with a peaceful strike which violated the statutory duty to arbitrate imposed by the Railway Labor Act. The Court concluded that a strike in violation of a statutory arbitration duty was not the type of situation to which the Norris-LaGuardia Act was responsive, that an important federal policy was involved in the peaceful settlement of disputes through the statutorily mandated arbitration procedure, that this important policy was imperiled if equitable remedies were not available to implement it, and hence that Norris-LaGuardia’s policy of nonintervention by the federal courts should yield to the overriding interest in the successful implementation of the arbitration process.
  The principles elaborated in Chicago River are equally applicable to the present case. To be sure, Chicago River involved arbitration procedures established by statute. However, we have frequently noted, in such cases as Lincoln Mills, the Steelworkers Trilogy, and Lucas Flour, the importance that Congress has attached generally to the voluntary settlement of labor disputes without resort to self-help and more particularly to arbitration as a means to this end. Indeed, it has been stated that Lincoln Mills, in its exposition of § 301 (a), “went a long way towards making arbitration the central institution in the administration of collective bargaining contracts.”
  The Sinclair decision, however, seriously undermined the effectiveness of the arbitration technique as a method peacefully to resolve industrial disputes without resort to strikes, lockouts, and similar devices. Clearly employers will be wary of assuming obligations to arbitrate specifically enforceable against them when no similarly efficacious remedy is available to enforce the concomitant undertaking of the union to refrain from striking. On the other hand, the central purpose of the Norris-LaGuar-dia Act to foster the growth and viability of labor organizations is hardly retarded — if anything, this goal is advanced — by a remedial device that merely enforces the obligation that the union freely undertook under a specifically enforceable agreement to submit disputes to arbitration. We conclude, therefore, that the unavailability of equitable relief in the arbitration context presents a serious impediment to the congressional policy favoring the voluntary establishment of a mechanism for the peaceful resolution of labor disputes, that the core purpose of the Norris-LaGuardia Act is not sacrificed by the limited use of equitable remedies to further this important policy, and consequently that the Norris-LaGuardia Act does not bar the granting of injunctive relief in the circumstances of the instant case.
  V
  Our holding in the present case is a narrow one. We do not undermine the vitality of the Norris-LaGuardia Act. We deal only with the situation in which a collective-bargaining contract contains a mandatory grievance adjustment or arbitration procedure. Nor does it follow from what we have said that injunctive relief is appropriate as a matter of course in every case of a strike over an arbitrable grievance. The dissenting opinion in Sinclair suggested the following principles for the guidance of the district courts in determining whether to grant injunctive relief — principles that we now adopt:
  “A District Court entertaining an action under § 301 may not grant injunctive relief against concerted activity unless and until it decides that the case is one in which an injunction would be appropriate despite the Norris-LaGuardia Act. When a strike is sought to be enjoined because it is over a grievance which both parties are contractually bound to arbitrate, the District Court may issue no injunc-tive order until it first holds that the contract does have that effect; and the employer should be ordered to arbitrate, as a condition of his obtaining an injunction against the strike. Beyond this, the District Court must, of course, consider whether issuance of an injunction would be warranted under ordinary principles of equity — whether breaches are occurring and will continue, or have been threatened and will be committed; whether they have caused or will cause irreparable injury to the employer; and whether the employer will suffer more from the denial of an injunction than will the union from its issuance.” 370 U. S., at 228. (Emphasis in original.)
  In the present case there is no dispute that the grievance in question was subject to adjustment and arbitration under the collective-bargaining agreement and that the petitioner was ready to proceed with arbitration at the time an injunction against the strike was sought and obtained. The District Court also concluded that, by reason of respondent’s violations of its no-strike obligation, petitioner “has suffered irreparable injury and will continue to suffer irreparable injury.” Since we now overrule Sinclair, the holding of the Court of Appeals in reliance on Sinclair must be reversed. Accordingly, we reverse the judgment of the Court of Appeals and remand the case with directions to enter a judgment affirming the order of the District Court.
  It is so ordered.
  Mr. Justice Marshall took no part in the decision of this case.

  Shortly after Sinclair was decided, an erosive process began to weaken its underpinnings. Various authorities suggested methods of mitigating the absolute rigor of the Sinclair rule. For example, the Court of Appeals for the Fifth Circuit held that Sinclair does not prevent a federal district court from enforcing an arbitrator’s order directing a union to terminate work stoppages in violation of a no-strike clause. New Orleans Steamship Assn. v. General Longshore Workers, 389 F. 2d 369, cert. denied, 393 U. S. 828 (1968); see Pacific Maritime Assn. v. International Longshoremen, 304 F. Supp, 1316 (D. C. N, D. Cal. 1969). See generally Keene, The Supreme Court, Section 301 and No-Strike Clauses: From Lincoln Mills to Avco and Beyond, 15 Vill. L. Rev. 32 (1969).
  Section 301 (a) suits require neither the existence of diversity of citizenship nor a minimum jurisdictional amount in controversy. All § 301 (a) suits may be removed pursuant to 28 TJ. S. C. § 1441.
  The view that state court jurisdiction would not be disturbed by § 301 (a) was perhaps most clearly articulated by Senator Ferguson, a spokesman for that provision, in a Senate debate in 1946:
  “Mr. FERGUSON. Mr. President, there is nothing whatever in the now-being-considered amendment which takes away from the State courts all the present rights of the State courts to adjudicate the rights between parties in relation to labor agreements. The amendment merely says that the Federal courts shall have jurisdiction. It does not attempt to take away the jurisdiction of the State courts, and the mere fact that the Senator and I disagree does not change the effect of the amendment.
  “Mr. MURRAY. But it authorizes the employers to bring suit in the Federal courts, if they so desire.
  “Mr. FERGUSON. That is correct. That is all it does. It takes away no jurisdiction of the State courts.” 92 Cong. Rec. 5708.
  The legislative history of the federal question removal provision is meager, but it has been suggested that its purpose was the same as original federal question jurisdiction, enacted at the same time in the Judiciary Act of 1875, 18 Stat. 470, namely, to protect federal rights, see H. Hart & H. Wechsler, The Federal Courts and the Federal System 727-733 (1953), and to provide a forum that could more accurately interpret federal law, see Mishkin, The Federal “Question” in the District Courts, 53 Col. L. Rev. 157, 159 (1953). 113 U. Pa. L. Rev. 1096, 1098 and n. 17 (1965).
  See, e. g., Bartosic, Injunctions and Section 301: The Patchwork of Avco and Philadelphia Marine on the Fabric of National Labor Policy, 69 Col. L. Rev. 980 (1969); Dunau, Three Problems in Labor Arbitration, 55 Va. L. Rev. 427 (1969).
  It is true that about one-half of the States have enacted so-called “little Norris-LaGuardia Acts” that place various restrictions upon the granting of injunctions by state courts in labor disputes. However, because many States do not bar injunctive relief for violations of collective-bargaining agreements, in only about 14 jurisdictions is there a significant Norris-LaGuardia-type prohibition against equitable remedies for breach of no-strike obligations. See Bartosic, supra, n. 14, at 1001-1006; Keene, supra, n. 10, at 49 and nn. 79, 80.
  We held in Teamsters Local 174 v. Lucas Flour Co., supra, that, even in the absence of an express no-strike clause in the collective-bargaining contract, an agreement that certain disputes “will be exclusively covered by compulsory terminal arbitration” (369 U. S., at 106) gives rise to an implied promise by the union not to strike during the term of the contract in response to these arbitrable disputes. Id., at 104-106. In the present case, there was an express no-strike clause in the union-management contract. See n. 4, supra.
  As the neutral members of the A. B. A. committee on the problems raised by Sinclair noted in their report:
  “Under existing laws, employers may maintain an action for damages resulting from a strike in breach of contract and may discipline the employees involved. In many cases, however, neither of these alternatives will be feasible. Discharge of the strikers is often inexpedient because of a lack of qualified replacements or because of the adverse effect on relationships within the plant. The damage remedy may also be unsatisfactory because the employer’s losses are often hard to calculate and because the employer may hesitate to exacerbate relations with the union by bringing a damage action. Hence, injunctive relief will often be the only effective means by which to remedy the breach of the no-strike pledge and thus effectuate federal labor policy.” A. B. A. Sinclair Report 242.
  Scholarly criticism of Sinclair has been sharp, and it appears to be almost universally recognized that Sinclair, particularly after Avco, has produced an untenable situation. The commentators are divided, however, with respect to proposed solutions, some favoring reconsideration of Sinclair, others suggesting extension of Sinclair to the States, and still others recommending that any action in this area be left to Congress. See generally Aaron,, Strikes in Breach of Collective Agreements: Some Unanswered Questions, 63 Col. L. Rev. 1027 (1963); Aaron, The Labor Injunction Reappraised, 10 U. C, L. A.

  As well stated by the neutral members of the A. B. A. Sinclair committee:
  “Any proposal which would subject unions to injunctive relief must take account of the Norris-LaGuardia Act and the opposition expressed in that Act to the issuing of injunctions in labor disputes. Nevertheless, the reasons behind the Norris-LaGuardia Act seem scarcely applicable to the situation ... [in which a strike in violation of a collective-bargaining agreement is enjoined]. The Act was passed primarily because of widespread dissatisfaction with the tendency of judges to enjoin concerted activities in accordance with ‘doctrines of tort law which made the lawfulness of a strike depend upon judicial views of social and economic policy.’ [Citation omitted.] Where an injunction is used against a strike in breach of contract, the union is not subjected in this fashion to judicially-created limitations on its freedom of action but is simply compelled to comply with limitations to which it has previously agreed. Moreover, where the underlying dispute is arbitrable, the union is not deprived of any practicable means of pressing its claim but is only required to submit the dispute to the impartial tribunal that it has agreed to establish for this purpose.” A.
