OPINION OF THE COURT
Southeastern Pennsylvania Transportation Authority (SEPTA) appeals by allowance an order of Superior Court1 affirming Philadelphia Court of Common Pleas’ denial of SEPTA’s preliminary objections challenging its jurisdiction to hear and decide the case.2 We affirm.
*394I.
The sole question for our consideration is whether a public employee is totally precluded from obtaining any relief directly or indirectly, involving his public employer, for discharge in arguable breach of a collective bargaining agreement when the union has violated its duty of fair representation by failing in bad faith to pursue his grievance to impartial arbitration. SEPTA bases its main argument on its interpretation of Ziccardi v. Commonwealth, 500 Pa. 326, 456 A.2d 979 (1982), arguing that Common Pleas lacked jurisdiction over Martino’s equity suit against SEPTA for wrongful discharge because Section 903 of the Public Employe Relations Act (PERA), Act of July 23,1970, P.L. 563, No. 195, 43 P.S. § 1101.903, makes grievance arbitration the public employee’s exclusive remedy against a public employer for breaches of the bargaining agreement and does not compel the signatories to the bargaining agreement to proceed to arbitration.
We held in Ziccardi that generally an employee cannot seek reinstatement directly from a court even though the union’s failure to pursue a discharge to arbitration was in bad faith. However, where necessary to provide a meaningful remedy by arbitration, when that remedy is denied by the union’s fraud or bad faith, the employer can be joined in the employee’s action against the union for its bad faith breach of fiduciary duty and the chancellor may fashion an appropriate equitable remedy which would permit grievance arbitration nunc pro tunc.3
*395II.
SEPTA discharged Martino on August 4, 1977 alleging that he made improper fare collections. Pursuant to a collective bargaining agreement between SEPTA and the Union, the Union processed Martino’s grievance through the three permitted levels of grievance hearings. The Union represented Martino at each hearing and each hearing resulted in a decision against Martino. The Union then declined to seek impartial arbitration which is the statutorily prescribed remedy under the collective bargaining agreement for grievances unresolved by the three step internal procedure.
In his complaint, Martino sought relief against SEPTA for allegedly discharging him in violation of the collective bargaining agreement. He also sought relief against the Union for alleged breach of its duty of fair representation in, inter alia, failing to submit his discharge case to arbitration. He further claimed that he had exhausted the remedies available to him under the collective bargaining agreement. In Count Two, Martino claimed that his discharge was unsupported by competent or substantial evidence and that SEPTA based its decision at the grievance hearings on irrelevant and immaterial evidence. Martino did not allege that SEPTA had in any way participated in the Union’s breach of its duty of fair representation. Here he seeks an order compelling the Union and SEPTA to participate in an arbitration proceeding nunc pro tunc and he also asserts a claim against SEPTA under 42 U.S.C. § 1983.4
Common Pleas overruled SEPTA’s preliminary objection that Martino failed to exhaust the contractual grievance *396procedure, concluding that Vaca v. Sipes, 386 U.S. 171, 87 S.Ct. 903, 17 L.Ed.2d 842 (1967) and Falsetti v. Local Union No. 2026, UMWA, 400 Pa. 145, 161 A.2d 882 (1960) had reached diametrically opposite conclusions and for that reason, the jurisdictional issue was not clear and free from doubt.5 Superior Court affirmed en banc on reargument holding that Common Pleas had jurisdiction of the controversy because it fell within the general class of cases within Common Pleas’ original jurisdiction and the contractual grievance procedure did not oust Common Pleas of jurisdiction.6
III.
It is well settled that a court of equity has jurisdiction and, in furtherance of justice, will afford relief if the statutory or legal remedy is inadequate, or if equitable relief is necessary to prevent irreparable harm. Shenango Valley Osteopathic Hospital v. Department of Health, 499 Pa. 39, 451 A.2d 434 (1982); Pennsylvania State Chamber of Commerce v. Torquato, 386 Pa. 306, 125 A.2d 755 (1956), cert. denied sub nom., Bowman v. Pennsylvania Chamber of Commerce, 352 U.S. 1024, 77 S.Ct. 589, 1 L.Ed.2d 596 (1957).
Unlike the aggrieved employee in Ziccardi, Martino seeks arbitration of his grievance rather than a direct contract *397remedy against his employer. In Ziccardi we did not consider ñor did we preclude joining the employer where necessary to provide a just and effective remedy.7 In cases of the type we consider here, the employer approaches the status of an indispensable party to the litigation in the sense that the dispute cannot be finally resolved with equity and good conscience without his participation. See Shell Development Co. v. Universal Oil Co., 157 F.2d 421 (3d Cir.1946); Pa.R.C.P. 1032.
We therefore further define Ziccardi by holding that an employee may seek in equity under either our state or federal law by joining his employer where the union breaches its duty of fair representation when such joinder is necessary to afford him an adequate remedy. However, the union’s misconduct should not deprive the employer of all the procedural and substantive benefits of the bargained for grievance procedure, a procedure which PERA mandates. Therefore, we also hold that the employee’s relief under PERA is limited to an order from the chancellor compelling arbitration of the underlying grievance. The imposition of that limitation and its restriction to cases seeking relief under PERA requires an examination of the development of the federal law in this area and its relation to our state policies concerning public sector bargaining.
Both before and since Vaca v. Sipes, 386 U.S. 171, 87 S.Ct. 903, 17 L.Ed.2d 842 (1967), the United States Supreme Court has vacillated on whether an employee has a right to judicial relief under federal law for breach of contract against his employer when his union improperly fails or refuses to arbitrate his grievance, as well as on the nature of the relief to which he may be entitled.8
*398In Falsetti v. Local Union No. 2026 United Mine Workers, supra, a pre- Vaca case arising under the federal Labor *399Management Relations Act of 1947 (LMRA), 29 U.S.C. § 185, this Court considered the question of the employee’s right to sue his employer in equity for wrongful discharge where the union has breached its duty of fair representation.9 In Falsetti, the employee filed a complaint in equity against his former employer and named officials of his union for an alleged wrongful discharge from his employment. The employee sought reinstatement, restoration of his seniority rights and damages. Thereafter the union expelled him from membership. The employee then amended his complaint to also allege wrongful expulsion from union membership. Initially, we determined that the employee misjoined the causes of action. We then held that the trial court lacked jurisdiction of either claim.
In addition, we held that the employee could not maintain a cause of action against his union officials for breach of their duty of fair reprsentation. Instead, we said such a claim was limited to an action agianst the union itself for breach of its “fiduciary obligation.” In holding that Common Pleas lacked jurisdiction of the employee’s claim against his employer, we determined that the enforcement of third-party rights under the collective bargaining agreement between the International Union and the Company must be derived solely from the agreement itself. We stated:
We have carefully read the entire Agreement and can find no provision which authorizes appellant to enforce it. Although the seniority provisions relied upon inure directly for the benefit of the appellant-employee and do not exist simply to protect the interests of the Union, appel*400lant’s cause of action is precluded by a contractual grievance and arbitration procedure which, by its very terms, limits access thereto to the Union. The parties in drafting this Agreement provided for a simple expeditious and inexpensive grievance procedure to be administered by persons intimately familiar therewith. The procedure outlined was designed not only to promote settlement, but also to foster more harmonious employer-employee and employer-union relations. The parties expressly sought to avoid litigation, recognizing that the courts are particularly ill-equipped to assume the role of umpire in industrial disputes.

Prior to Vaca, with the law developing as outlined, see supra n. 8, at 397-399, some courts barred employee equity actions against the employer in order to effectuate a broad public policy that the union had exclusive control over the enforecement of the employer’s contract obligations in a collective bargaining agreement. These courts, seeing only the polar alternatives of a full remedy or none at all, reasoned “[t]o allow each individual employee to overrule and supersede the governing body of a union would create a condition of disorder and instability which would be disastrous to labor as well as industry.” Biancullo v. Brooklyn v. Union Gas Co., 19 Lab.Arb. 83, 85 (N.Y.Sup.Ct.1952), quoted in A. Cox Rights Under a Labor Agreement, 69 Harv.L.Rev. 601, 651 (1956). See also United States v. Voges, 124 F.Supp. 543 (E.D.N.Y.1954).
However, some commentators felt the competing policy of preventing injustice to the individual employee whose interest, including his interest in retaining his job, is flouted by the union sometimes justifies an exception:
While the rule which bars an individual employee from bringing an action on the contract when the union is unwilling to take the case to arbitration is sound if the union has made an adjustment or is satisfied that the grievance lacks merit, nevertheless it would work injus*401tice in situations where the union is unwilling to press the claim because of indifference or reluctance to suffer the expense. ... One solution would be to open arbitration proceedings to individual grievants. Another alternative is to allow the employee to bring suit against the employer and union as codefendants upon analogy to the bill in equity which the beneficiary of a trust may maintain against the trustee who fails to press a claim against a third person. The suit would fail on the merits if it appeared that the collective bargaining representative had dropped the grievance for lack of merit or had negotiated a reasonable adjustment. Perhaps the wisest solution is to give the union a choice between (a) preserving the single uniform method of administering the contract by permitting the employee to use its name at his own expense in carrying the case to the higher steps of the grievance procedure and ultimately to arbitration and (b) suffering an independent suit against it and the employer.
Cox, supra, at 652 (footnote omitted).
Then in 1967, in Vaca v. Sipes, the United States Supreme Court held that a state court had jurisdiction of an individual union member’s action against officers and representatives of his employment in violation of the collective bargaining agreement and that the union had arbitrarily and without cause refused to take the grievance to arbitration. 386 U.S. at 186. The Vaca Court also stated that a wrongfully discharged employee may bring an action against his employer under Section 301 of the LMRA in the face of a defense based upon failure to exhaust contractual remedies. See also Hines v. Anchor Motor Freight, Inc., 424 U.S. 554, 96 S.Ct. 1048, 47 L.Ed.2d 231 (1976). The Vaca Court did, however, require the employee to first prove that his union breached its duty of fair representation in handling the employee’s grievance. It reasoned:
[ajnother situation when the employee may seek judicial enforcement of this contractual rights arises if, as is true here, the union has sole power under the contract to *402invoke the higher stages of the grievance procedure, and if, as is alleged here, the employee-plaintiff has been prevented from exhausting his contractual remedies by the union’s wrongful refusal to process the grievance. ... [T]he employer in such a situation may have done nothing to prevent exhaustion of the exclusive contractual remedies____ But the employer has committed a.. .breach of that agreement.. .which could be remedied through the grievance process.. .were it not for the union’s breach of its statutory duty of fair representation____ To leave the employee remediless in such circumstances would, in our opinion, be a great injustice.
386 U.S. at 185-86, 87 S.Ct. at 914-15 (emphasis in original).
The Court then considered the employee’s appropriate remedy in such actions. It first determined that an order compelling arbitration is an available remedy because the employee’s action is based on the employer’s wrongful breach of the collective bargaining agreement coupled with the union’s alleged wrongful failure to afford him his contractual remedy. The Supreme Court declined, however, to require arbitration in all cases. It stated that:
[T]he employee’s action is based on the employer’s alleged breach of contract plus the union’s alleged wrongful failure to afford him his contractual remedy of arbitration. For this reason, an order compelling arbitration should be viewed as one of the available remedies____ But we see no reason inflexibly to require arbitration in all cases. In some cases, for example, at least part of the employee’s damages may be attributable to the union’s breach of duty, and an arbitrator may have no power under the bargaining agreement to award such damages against the union. In other cases, the arbitrable issues may be substantially resolved in the course of trying the fair representation controversy. In such situations, the court should be free to decide the contractual claim and to award the employee appropriate damages or equitable relief.
*403Id. at 196, 87 S.Ct. at 920. As set forth in Part IV of this opinion, we do not find that reasoning, which would entrust resolution of the merits of the underlying grievance to the court rather than the arbitrator, persuasive. We will not, therefore, apply it in a case arising under PERA.10
The Vaca court also determined that the damages must be apportioned between the employer and the union according to the damages caused by the fault of each. Thus, the “damages attributable solely to the employer’s breach of contract should not be charged to the union, but increases if any in those damages caused by the union’s refusal to process the grievance should not be charged to the employer.” 386 U.S. at 197-98, 87 S.Ctat 920-21.
Despite the clear language in Vaca requiring apportionment of damages between the employee and the union according to the fault of each, the Vaca Court declined to hold the union responsible to backpay accrued because of its failure to pursue arbitration. See Bowen v. U.S. Postal Services, 459 U.S. 212, 103 S.Ct. 588, 74 L.Ed.2d 402 (1983). In Vaca the employer discharged the employee on January 8, 1960. In early February, 1961, the union refused to take the grievance to arbitration. The employee’s suit was not tried until June, 1964. A factfinder could reasonably have found that an arbitrator, had he heard the case, would have probably issued an award sometime in 1961. The Vaca Court, however, determined the union’s share of damages was de minimis. See also Czosek v. O’Mara, 397 U.S. 25, 90 S.Ct. 770, 25 L.Ed.2d 21 (1970); Milstead v. Internation*404al Brotherhood of Teamster, 649 F.2d 395 (6th Cir.), cert. denied, 454 U.S. 896, 102 S.Ct. 394, 70 L.Ed.2d 211.
In an effort to dispel the confusion on the damage question Vaca created, the Bowen Court elaborated on the apportionment of damages issue to fairly allocate responsibility to each party for its own wrongful act. Bowen held that an employer who wrongfully discharges an employee protected by a collective bargaining agreement containing an- arbitration clause, is only responsible for backpay that accrues prior to the hypothetical date upon which an arbitrator would have issued an award had the employee’s union taken the matter to arbitration. Bowen further held that the union is responsible for backpay subsequent to the hypothetical arbitration date. The Court justified this additional burden on the union as follows:
The employer... must rely on the union’s decision not to pursue an employee’s grievance____ Just as a nonorganized employer may accept an employee’s waiver of any challenge to his discharge as a final resolution of the matter, so should an organized employer be able to rely on a comparable waiver by the employee’s exclusive representative.
...By seeking and acquiring the exclusive right and power to speak for a group of employees, the union assumes a corresponding duty to discharge that responsibility faithfully — a duty which it owes to the employees whom it represents and on which the employer with whom it bargains may rely. When the union, as the exclusive agent of the employee, waives arbitration or fails to seek review of an adverse decision, the employer should be in substantially the same position as if the employee had had the right to act on his own behalf and had done so.
Id. 459 at 225-26, 103 S.Ct. at 596-97.
IV.
With this history of employee suits under federal labor law in mind, we turn to PERA, the state labor statute in *405question here. PERA applies only to public employers and certain public employees.11 Specifically, PERA defines a public employer as one not subject to either the Pennsylvania Labor Relations Act, 43 P.S. § 211.1 et seq., or the LMRA. While the federal cases discussed in Part III of this opinion interpreting the rights of employees to sue their unions and employers under the LMRA are instructive, they are not authoritative on cases arising under PERA. Pennsylvania Labor Relations Board v. State College Area School District, 461 Pa. 494, 337 A.2d 262 (1975). In State College we stated:
The distinction between the public and private sector cannot be minimized. Employers in the private sector are motivated by the profit to be returned from the enterprise whereas public employers are custodians of public funds and mandated to perform governmental functions as economically and effectively as possible. The employer in the private sector is constrained only by investors who are most concerned with the return for their investment whereas the public employer must adhere to the statutory enactments which control the operation of the enterprise.
Id., 461 Pa. at 499-500, 337 A.2d at 264.
With the distinction between public and private sector employer-employee relations in mind we turn finally to Section 903 of PERA. It provides:
Arbitration of disputes or grievances arising out of the interpretation of the provisions of a collective bargaining agreement is mandatory. The procedure to be adopted is a proper subject of bargaining with the proviso that the final step shall provide for a binding decision by an arbitrator or a tri-partite board of arbitrators as the parties may agree.
43 P.S. § 1101.903.
The policy favoring arbitration of labor disputes is embodied in both PERA and the LMRA. However, PERA makes arbitration of all disputes arising under public sector collec*406tive bargaining agreements the exclusive remedy for unresolved grievances not involving police officers or firemen. As we observed in note 10, supra, at 248, the LMRA merely permits arbitration although federal case law generally encourages it. See 29 U.S.C. § 203(d); United States Steel Workers v. American Manufacturing, supra. See also Board of Education v. Philadelphia Federation of Teachers, 464 Pa. at 99, 346 A.2d at 39.
The coupling of collective bargaining with grievance arbitration is the genius of American labor law. It is the grievance procedure, capped by the possibility of arbitration in a limited number of cases, which insures peace in the workplace during a contract’s term. It does so by providing an efficient mechanism for dispute resolution by persons knowledgeable in labor-management problems. Arbitrators under collective bargaining agreements are indispensible to a workable collective bargaining process. Since freedom from strife is especially important in the public sector our legislature made arbitration a cornerstone of its policy in that sector by elevating it from a favored to an exclusive remedy. See Board of Education v. Philadelphia Federation of Teachers, supra. See also Edwards, The Developing Labor Relations Law in the Public Sector, 10 Duquesne Law Review 357 (1972).
In Ziccardi we balanced the respective interests and roles of the public employer, its employees and the employees’ collective bargaining agent with PERA’s arbitration mandate and simply enforced the provision of the collective bargaining agreement concerning grievance arbitration, which gave the union exclusive power to bring employee grievances to arbitration. We therefore held a public employee has no right to sue his employer for wrongful discharge when the union has refused to proceed to arbitration unless the employer participated in the union’s breach of its duty of fair representation. We stated:
By giving the employee an unfettered right to sue the employer for the union’s bad faith, we would relieve the wrongdoer of any effective sanction, make the plaintiff *407whole at the expense of an innocent party and bind that innocent party by the action of the plaintiff’s agent, over whom it has no control. This would be in total violation of the principles of the law of agency. Furthermore, any attempt by the employer to exercise control over the union in such matters violates fundamental principles of labor law concerning the right of the bargaining agent and its members to be free of employer coercion.
500 Pa. at 332, 456 A.2d at 982.12 See also McCluskey v. PennDOT, 37 Pa. Commonwealth Ct. 598, 391 A.2d 45 (1978).
Ziccardi does preclude an employee from directly seeking reinstatement in a court action for wrongful discharge;13 it does not prevent an equity court from fashioning a remedy which will effectutate the parties’ collective bargaining agreement so long as its decree insures compliance with *408PERA’s requirement of mandatory grievance arbitration. In requiring mandatory arbitration of public employees’ grievances, the legislature certainly did not intend to shield the employer from the natural consequences of its breach of the collective bargaining agreement, nor did the legislature intend to deprive employees of the right, under proper circumstances, to seek equitable relief compelling pursuit of the statutorily prescribed grievance arbitration procedures under a collective bargaining agreement precluding the employee from seeking his statutory remedy. Thus, the Chancellor may, under proper circumstances, order the union and employer to arbitrate the aggrieved employee’s grievance; and, where the arbitrator deems it appropriate, he may order reinstatement.
Our legislature mandates that:
In all cases where a remedy is provided or a duty is enjoined or anything is directed to be done by any statute, the directions of the statute shall be strictly pursued, and no penalty shall be inflicted, or anything done agreeably to the common law, in such cases, further than shall be necessary for carrying such statute into effect.
1 Pa.C.S. § 1504. Our holding that the chancellor lacks authority to resolve the underlying grievance is consistent with that statutory provision and the strong policy favoring arbitration of public sector grievances embodied in Section 903 of PERA. Moreover, our holding that the chancellor may, if the employee establishes the union’s breach of its duty of fair representation, order arbitration of the underlying grievance nunc pro tunc provides the employee with a complete and adequate legal remedy.14 See D. Feller, A General Theory of the Collective Bargaining Agreement, 61 Cal.L.Rev. 663, 813 (1976).15
*409We are also persuaded by Bowen that such relief must limit the employer’s liability for backpay to the period from the date of wrongful discharge to the date when arbitration would normally have commenced. In the absence of an apportionment providing meaningful sanctions against the union, incentives to comply with the grievance procedure would be diminished. See Bowen, supra16 See also Ziccardi, 500 Pa. at 332, 456 A.2d at 982.
In conclusion, we hold today that before a court in equity may entertain a complaint seeking to order arbitration, the complainant must prove that the union acted in bad faith towards its member. Once it has been determined that the union breached its duty of fair representation, the
*410Court of Common Pleas sitting in equity many order the completion of the arbitration procedure and, in cases governed by state labor law its power is limited to that remedy. The only matter before the arbitrator would be to determine whether or not the complainant was wrongfully discharged and to apportion damages for backpay in a manner consistent with this opinion, if the arbitrator concludes backpay is warranted. Under this procedure, a wrongfully discharged employee receives precisely the treatment all the employees in the unit are entitled to under the collective bargaining agreement. Based on the foregoing, the order of the Superior Court is affirmed and the record is remanded to Common Pleas for further proceedings consistent with this opinion.
