In this case, we are asked to
determine whether a union’s unexplained failure to process a member’s grievance constitutes a breach of the union’s duty of fair representation.1
*656I
Plaintiffs belonged to a group of sanitation laborers, known as white wingers, within the Environmental Protection and Maintenance Department (EPMD) of defendant City of Detroit. They wore white uniforms, and their duties consisted of picking up refuse from city streets with a hand shovel and a broom and placing it in white wheeled barrels which they pushed. Plaintiffs were represented exclusively by defendant labor union. The position of white winger was considered a light-duty job and, prior to the summer of 1975, the city’s practice was to assign that duty, for the most part, to individuals who were physically unable to work on its garbage truck crews.
However, under a 1973 collective-bargaining agreement between the city and the union, employees in the job classification of sanitation laborer were all subject to the same job duties. In the summer of 1975, the city ordered the white wingers to submit to physical examinations in order to determine if they were physically able to perform all duties required of sanitation laborers. Subsequently, several white wingers were retired, placed on leaves of absence, or placed on workers’ compensation. On September 8, 1975, a number of the white wingers contacted the union steward concerning the city’s apparently new policy. Ten days later, a conference was held between the city and the union to discuss the situation. However, the city adhered to its position that all workers within the sanitation laborer classification had to fulfill all job duties._
*657The next day, September 19, 1975, the city gave the union the following written notice:
"Employees who cannot perform regular job assignments because of failing health are eligible for sick leave according to the master agreement. Failing health is a personal problem, and we do not have light jobs in this department.”
On September 30, 1975, the union instituted grievance proceedings on behalf of plaintiffs.2 The first two steps of the grievance procedure were waived and, on October 9, 1975, the grievances were denied at the third step by the City Commission Administrative Coordinator. Under article 8 of the collective-bargaining agreement, defendant union had 15 days to proceed to step four of the *658grievance procedure by referring the grievance to the Appeal and Review Board. At a Local 26 union meeting conducted on October 24, 1975, members were told that the grievances were being processed by Council 77. Also, the District Council 77 executive director testified before the hearing referee that, as a matter of policy, he processed all step-three grievances to step four. In fact, defendant union did not proceed to step four within the 15-day time period.
On February 17, 1976, plaintiffs filed unfair labor practice charges, alleging that the city had improperly influenced union affairs to plaintiffs’ detriment and that the union had breached its duty of fair representation.
The hearing referee found, and no one disputes, that the failure to process the grievance was without explanation:
"In the present case, the white wing grievance stopped at the third step. What happened to it is a matter of conjecture. Local union president Robertson testified he pushed for arbitration. Council 77 personnel say they didn’t get the request, which brings up three possibilities. First, the local didn’t press the matter the way they said they would by written request through union channels. Secondly, Council 77 mishandled the grievance processing or thirdly, that someone in the local or council purposely dropped the entire thing. From the testimony, it appears as though either the local or Council 77 representatives mishandled the grievance by neglecting to follow procedure, to process the grievance to arbitration. The question is, then, is this lack of action, arguably, an unfair labor practice under PERA — without any further inquiry as to merit or lack of it in the grievance itself?
"In this case, there is an absence of evidence of purpose (or motive, if you will) to the failure of the union local or council to pursue the grievance. The *659subject matter had been the object of a special conference with the city. Both the local union and the union council, though passing the blame for failure to process back and forth, apparently show no hostility, animosity, or invidious motivation toward any of the white wingers, or their claim. At best, from the viewpoint of the charging party, the union local or council did not efficiently do as they said they would. Absent other considerations, such action is not, in the opinion of this writer, an unfair labor practice under Michigan law”.
Accordingly, the referee recommended dismissal of the action and, on August 11, 1979, the Michigan Employment Relations Commission issued its decision, adopting that recommendation:
"Where the union has vigorously pursued the grievance through three steps of the grievance procedure and no animosity is shown, we will presume that the union has fulfilled its collective-bargaining obligation. There is insufficient evidence to prove that the union’s handling of the grievance was discriminatory or that the employer affected its handling. The apparent negligence in failing to request arbitration does not constitute a breach of the duty of fair representation, where no unlawful intent has been proven. [Local 542, Council 77,] American Federation of State, County & Municipal Employees, AFL-CIO [v Rupinski], 1977 MERC Lab Op 861. We find that no breach of the union’s duty took place and the [hearing referee’s] disposition of this case is correct.”
The Court of Appeals affirmed the MERC:
"There is insufficient evidence to prove under Vaca [v Sipes, 386 US 171; 87 S Ct 903; 17 L Ed 2d 842 (1967)] or Lowe [v Hotel & Restaurant Employees Union, Local 705, 389 Mich 123; 205 NW2d 167 (1973)] that the union’s conduct was arbitrary, discriminatory or in bad faith. The failure to request arbitration does not consti*660tute a breach of the duty of fair representation, where no unlawful intent has been proven.”3
We granted leave to appeal on August 23, 1983.4
II
Essentially, plaintiffs claim that both the MERC and the Court of Appeals erred by requiring them to show unlawful intent in order to establish a breach of the union’s duty of fair representation. It is clear that a labor organization has a duty, imposed by various labor law statutes,5 to fairly represent its members.
*661"The statutory duty of fair representation was developed over 20 years ago in a series of cases involving alleged racial discrimination by unions certified as exclusive bargaining representatives under the Railway Labor Act, see Steele v Louisville & N R Co, 323 US 192; 65 S Ct 226; 89 L Ed 173 [(1944)]; Tunstall v Brotherhood of Locomotive Firemen, 323 US 210; 65 S Ct 235; 89 L Ed 187 [(1944)], and was soon extended to unions certified under the NLRA, see Ford Motor Co v Huffman, [345 US 330; 73 S Ct 681; 97 L Ed 1048 (1953)]. Under this doctrine, the exclusive agent’s statutory authority to represent all members of a designated unit includes a statutory obligation to serve the interests of all members without hostility or discrimination toward any, to exercise its discretion with complete good faith and honesty, and to avoid arbitrary conduct. Humphrey v Moore, 374 US [335], 342; [84 S Ct 363;] 11 L Ed 2d [370 (1964)].
"A breach of the statutory duty of fair representation occurs only when a union’s conduct toward a member of the collective-bargaining unit is arbitrary, discriminatory, or in bad faith. See Humphrey v Moore, supra; Ford Motor Co v Huffman, supra. There has been considerable debate over the extent of this duty in the context of a union’s enforcement of the grievance and arbitration procedures in a collective-bargaining agreement.
"Though we accept the proposition that a union may not arbitrarily ignore a meritorious grievance or process it in perfunctory fashion, we do not agree that the individual employee has an absolute right to have his grievance taken to arbitration regardless of the provisions of the applicable collective-bargaining agreement.
*662"[T]he union’s statutory duty of fair representation protects the individual employee from arbitrary abuses of the settlement device by providing him with recourse against both employer (in a § 301 suit) and union * * *.
"In administering the grievance and arbitration machinery as statutory agent of the employees, a union must, in good faith and in a nonarbitrary manner, make decisions as to the merits of particular grievances. See Humphrey v Moore, [supra]; Ford Motor Co v Huffman, [supra]. * * * [T]he individual employee has no absolute right to have his grievance arbitrated under the collective-bargaining agreement at issue, and * * * a breach of the duty of fair representation is not established merely by proof that the underlying grievance was meritorious”. Vaca v Sipes, 386 US 171, 177, 190, 191, 193, 194-195; 87 S Ct 903; 17 L Ed 2d 842 (1967). Also International Brotherhood of Electrical Workers v Foust, 442 US 42, 46-47, 51; 99 S Ct 2121; 60 L Ed 2d 698 (1979).
This Court too has discussed the duty of fair representation.
"A labor union has a duty fairly to represent its members.
"This duty arises from the nature of the relationship between the union and its members. The union and its members do not deal at arms length.
"The union speaks for the member. It makes a contract of employment on his behalf. The union oifers its member solidarity with co-workers, expertise in negotiation, and faithful representation. In exchange, the member pays his union dues, and gives his support and loyalty to the union.
"In many ways, the relationship between a union and its member is a fiduciary one. Certainly, it is a relationship of fidelity, of faith, of trust, and of confidence.
"If the courts have stopped short of declaring the union and member relationship a fully fiduciary one, it *663is because the union, by its nature, has a divided loyalty.
"It must be faithful to each member, to be sure, but it must be faithful to all of the members at one and the same time.
"The union must be concerned for the common good of the entire membership. This is its first duty.
"That duty of concern for the good of the total membership may sometimes conflict with the needs, the desires, even the rights of an individual member.
"When the general good conflicts with the needs or desires of an individual member, the discretion of the union to choose the former is paramount.
"When the general good conflicts with the legal or civil rights of an individual member, the courts will recognize those rights and enforce them as against the will of the majority of the union membership.
"In the area of grievances, the courts have held that the union has considerable discretion to decide which grievances shall be pressed and which shall be settled. It has been said that the union has latitude to investigate claimed grievances by members against their employers, and has the power to abandon frivolous claims. Vaca v Sipes, 386 US 171; 87 S Ct 903; 17 L Ed 2d 842 (1967).
"It has been held that an individual member does not have the right to demand that his grievance be pressed to arbitration, and the union 'obviously’ is not required to carry every grievance to the highest level, but must be permitted to assess each with a view to individual merit. Gunkel v Garvey, 45 Misc 2d 435; 256 NYS2d 953 (1964).
"Having regard for the good of the general membership, the union is vested with discretion which permits it to weigh the burden upon contractual grievance machinery, the amount at stake, the likelihood of success, the cost, even the desirability of winning the award, against those considerations which affect the membership as a whole.
"In doing so, the courts have said that the union must act without fraud, bad faith, hostility, discrimination, arbitrariness, caprice, gross nonfeasance, collusion, bias, prejudice, wilful, wanton, wrongful and malicious *664refusal, personal spite, ill will, bad feelings, improper motives, misconduct, overreaching, unreasonable action, or gross abuse of its discretion in processing or refusing or failing to process a member’s grievance.” Lowe v Hotel & Restaurant Employees Union, Local 705, 389 Mich 123, 145-147; 205 NW2d 167 (1973). Also, see generally, Anno: Union’s Liability in Damages for Refusal or Failure to Process Employee Grievance, 34 ALR3d 884.
Although Vaca, supra, and Lowe, supra, appear to set forth a simple rule, they have engendered much debate over the requisite evidentiary proofs and burdens, especially as regards union enforcement of grievance procedures embodied in collective-bargaining agreements. In Vaca, supra, p 177, the Supreme Court of the United States made it clear that a union’s duty of fair representation is comprised of three distinct responsibilities: (1) "to serve the interests of all members without hostility or discrimination toward any”, (2) "to exercise its discretion with complete good faith and honesty”, and (3) "to avoid arbitrary conduct”. A union’s failure to comply with any one of those three responsibilities constitutes a breach of its duty of fair representation.
"A union must conform its behavior to each of these three separate standards. First, it must treat all factions and segments of its membership without hostility or discrimination. Next, the broad discretion of the union in asserting the rights of its individual members must be exercised in complete good faith and honesty. Finally, the union must avoid arbitrary conduct. Each of these requirements represents a distinct and separate obligation, the breach of which may constitute the basis for civil action.” Griffin v International Union, United Automobile, Aerospace & Agricultural Implement Workers of America UAW, 469 F2d 181, 183 (CA 4, 1972). Also Tedford v Peabody Coal Co, 533 F2d 952, 957 (CA 5, 1976); Ruzicka v General Motors Corp, 523 *665F2d 306, 309-310 (CA 6, 1975), reh den 528 F2d 912 (CA 6, 1975) (Ruzicka I).
Nevertheless, it must be kept in mind that
"[t]he major goal of the duty of fair representation is to identify and protect individual expectations as far as possible without undermining collective interests. Where the individual and collective group interests clash, the former must yield to the latter. When collective bargaining agreements are executed, there may be many provisions which lead individual employees to believe they are entitled to specified benefits but, in the final analysis, the collective group interests must remain paramount. The nature of any labor policy requires an election between preserving the group interests through democratic processes and adopting external restraints to protect the minority.” Tedford, supra, pp 956-957.
In this case, plaintiffs’ unfair labor practice charge against the union did not allege discriminatory conduct. However, it did allege that the union had acted in bad faith and arbitrarily. Nevertheless, it is undisputed that plaintiffs failed to present sufficient evidence upon which to find that the union acted in bad faith. Thus, the only question before us is whether plaintiffs presented sufficient evidence to find that the union breached its duty of fair representation by arbitrary conduct in the processing of their grievances.6
*666"As in this case, courts generally have little difficulty in applying the 'discriminatory’ and 'bad faith’ standards of conduct to the facts presented to them. However, there is significant uncertainty in the cases as to what constitutes 'arbitrary’ conduct and as to how arbitrary conduct is distinguishable from negligent conduct. See Barhitte v Kroger Co, 85 CCH Labor Cases ¶ 11,081 at p 20,231 (WD Mich, 1978). Due to this difficulty, the Court finds that some general discussion of what constitutes arbitrary and negligent conduct in fair representation cases is necessary.” Dutrisac v Caterpillar Tractor Co, 511 F Supp 719, 723 (ND Cal, 1981).
A. Federal Cases.
Since Vaca, supra, the United States Supreme Court has not spoken definitively to the problem before us. However, the federal district and circuit courts have had scores of suits raising the same issue, some on remarkably similar facts. Moreover, even though there has been disagreement over the conduct required by the three responsibilities composing the duty of fair representation, it has generally been recognized that Vaca enlarged that duty.
"Vaca’s 'repeated references to "arbitrary” union conduct reflects a calculated broadening of the fair representation standard.’ * * * Thus, an inexplicable failure to fully process a grievance, without a determination of its merit, has been held to be so negligent that it amounts to 'arbitrary and perfunctory’ handling.
"[However, i]t suffices that the union decides in good faith and on the basis of objective, rational criteria that the grievance lacks sufficient merit to justify the ex*667pense of arbitration.” Curth v Faraday, Inc, 401 F Supp 678, 681 (ED Mich, 1975).7
The Curth court, while acknowledging a union’s heightened responsibilities under the duty of fair representation, nevertheless blurred the distinctions between the three separate components of that duty. Indeed, although the plaintiff’s claim was one of arbitrary union conduct, the court went on to state that the fact that "the union refused to arbitrate a claim which it believed was meritorious * * * standing alone, supports neither an inference of bad faith nor one of discriminatory intent”. Id., p 682, fn 6.8 Finally, the court held that the union’s failure to arbitrate a grievance because of a lack of local union funds and because of a perception that the arbitrator would rule against the grievance did not constitute bad-faith or arbitrary conduct.
Subsequently, in a landmark, but different, case, the Sixth Circuit made the following comments which apply with equal force to Curth:
"We believe that the District Court misread Vaca when it held that 'bad faith’ must be read into the separate and independent standards of 'arbitrary’ or 'discriminatory’ treatment. Union action which is arbi*668trary or discriminatory need not be motivated by bad faith to amount to unfair representation.” Ruzicka I, supra, p 310.
The court found that the union’s unexplained failure to process a grievance within time limits prescribed by a collective-bargaining agreement, unrelated to the merits of the grievance, was negligent and "a clear example of arbitrary and perfunctory handling of a grievance” amounting to unfair representation. Id.
"[W]hen a union makes no decision as to the merit of an individual’s grievance but merely allows it to expire by negligently failing to take a basic and required step towards resolving it, the union has acted arbitrarily and is liable for a breach of its duty of fair representation.” Id.
Concurring, Judge McCree agreed with the result, but not the reasoning, of the majority.
"I do not believe that the local union’s handling of the grievance was 'arbitrary’ or 'perfunctory’ as the majority opinion determines.
"Arbitrary and perfunctory are adjectives characterizing intentional conduct that is capricious or superficial. Here there was an unintentional failure to act that prevented appellant’s grievance from being submitted to arbitration.
"Nevertheless, I would hold that when a statutorily established exclusive bargaining representative fails to file a statement that is a prerequisite for submission of an employee’s claim to arbitration, not because the union has made a good faith judgment for a lawful reason that it should not file the document, but merely because of its negligent omission, then it has breached its duty of fair representation.
"I do not suggest, however, that a union should be *669held liable for all negligence in processing an employee’s grievance.
"Nevertheless, I believe that a total failure to act, whether negligent or intentional, except for a proper reason, is behavior so egregious that, as in the case of bad faith, hostile discrimination, arbitrariness, or per-functoriness, the union should be held responsible.” Id., pp 315-316.
Thereafter, in applying Ruzicka I, it was stated that
"[i]f a union breaches its duty of fair representation in failing to process a grievance before determining its merit, it is certainly liable for failing to initiate a grievance after acknowledging its merit.” Ruggirello v Ford Motor Co, 411 F Supp 758, 760 (ED Mich, 1976).
The Sixth Circuit has also reaffirmed the proposition that
"[b]ad faith is not, however, a necessary element of proof when alleging arbitrary or discriminatory conduct by a union. [Ruzicka I, supra.] In some instances, it is necessary to show only that the union has processed a grievance in a perfunctory fashion. Vaca v Sipes, supra, * * *. Certainly the duty of fair representation may be breached whenever a union ineptly handles a grievance because it is ignorant of those contract provisions having a direct bearing on the case.” Milstead v International Brotherhood of Teamsters, Local Union No 957, 580 F2d 232, 235 (CA 6, 1978).
The court implied that the defendant’s conduct was perfunctory, i.e., breached its duty of fair representation, because it inadequately investigated the plaintiffs grievance and because it was unprepared to effectively present the grievance to a joint employer-employee grievance committee.
*670The Eighth Circuit, noting Ruzicka I, supra, has "indicate[d] * * * that in an appropriate case, improper motivation may not be required where perfunctory conduct is alleged and proved”. Ethier v United. States Postal Service, 590 F2d 733, 737, fn 3 (CA 8, 1979), cert den 444 US 826; 100 S Ct 49; 62 L Ed 2d 33 (1979). In Ethier, although a union steward missed a grievance filing deadline, his conduct was not inexplicable as in Ruzicka I. Rather, he "pursued the grievance with vigor and erred only in failing to anticipate how the Agreement's time limits] would ultimately be construed by an arbitrator”. Thus, there was no perfunctory conduct and no breach of the duty of fair representation. Ethier, supra, p 736.
In Wyatt v Interstate & Ocean Transport Co, 623 F2d 888, 890-891 (CA 4, 1980), the Fourth Circuit reaffirmed its view of the three distinct standards of conduct comprising the duty of fair representation which it first expressed in Griffin, supra. Then, citing, among other cases, Ruzicka I, it stated that
"[t]o sustain a member’s action against his union under Griffin standards, it is not necessary that the union’s breach be intentional. A union representative could be so indifferent to the rights of members or so grossly deficient in his conduct purporting to protect the rights of members that the conduct could be equated with arbitrary action. * * * In the final analysis the right of an individual employee to have his grievance processed depends on the provision of the applicable collective bargaining agreement and the facts of each case.” Wyatt, supra, p 891.
Nevertheless, the court also stated that "[liability for failure to represent, however, cannot be predicated upon simple negligence but must reach the degree of culpability discussed in Griffin, Harrison *671 [v United Transportation Union, 530 F2d 558 (CA 4, 1975), cert den 425 US 958; 96 S Ct 1739; 48 L Ed 2d 203 (1976)] and Vaca” Wyatt, supra, p 891.
The Sixth Circuit reiterated its view of Ruzicka I in Ruzicka v General Motors Corp, 649 F2d 1207, 1209 (CA 6, 1981) (Ruzicka II). Moreover, in Ruz-icka II, the court explained in greater detail the effect of its decision in Ruzicka I.
"In Ruzicka I we held that, absent justification or excuse, a union’s negligent failure to take a basic and required step, unrelated to the merits of the grievance, is a clear example of arbitrary and perfunctory conduct which amounts to unfair representation. 523 F2d 310. In our order denying the petition for rehearing, we observed that '[o]ur opinion in this action speaks to a narrow range of cases in which unexplained union inaction, amounting to arbitrary treatment, has barred an employee from access to an established union-management apparatus for resolving grievances.’ 528 F2d 913. The key to Ruzicka I, then, was our holding that 'unexplained union inaction’ which substantially prejudices a member’s grievance could amount to the type of arbitrary conduct which evidences unfair representation. The procedural posture of the appeal, coming to us as it did with an incomplete record, did not present an opportunity for us to make a final ruling as to the legal viability of any explanation the union might proffer. The district court was correct in ruling that since the dismissal was under [FR Civ P] 41(b), our holding was only that Ruzicka’s evidence was legally sufficient to constitute a prima facie case of unfair representation and the remand to the district court was for further proceedings in which the defendant could then present any evidence it might have.” Ruzicka II, supra, p 1211.
The court made it clear that, if the failure to comply with the collectively bargained grievance procedure time limits was due to reliance on past practice, i.e., the time limits were traditionally not enforced because extensions were freely granted, *672then the union did not breach its duty of fair representation by acting arbitrarily, perfunctorily, or ineptly. Id., pp 1211-1212. Also Ruzicka v General Motors Corp, 707 F2d 259 (CA 6, 1983), cert den — US —; 104 S Ct 424; 78 L Ed 2d 359 (1983) (Ruzicka III). The court emphasized that a mistaken reliance on past practice amounts to no more than ordinary negligence and that "we cannot hold a union liable for breach of the duty of fair representation based upon simple negligence”. Id., p 1212.
"[W]e see no reason to apply a stricter standard to a union’s untimely filing of a statement based on past practice than is applied to a union’s decision not to pursue a grievance that it believes to be without merit. In both cases, the union can articulate a sufficient legal rationale to justify the manner in which a grievance has been handled. Whatever the rationale, the standard against which it is judged should be uniform. A contrary conclusion would inject the court’s [sic] into the process of second-guessing a union representative’s decisions and would undermine a union’s ability to rely on prevailing practices. This view is supported by the decisions of the other circuits which are unanimous in holding that ordinary negligence, without more, cannot establish a breach of the duty of fair representation. * * * Of course, when a bargaining representative acts arbitrarily in failing to process a grievance submitted to it by an employee without a sound reason for its decision, i.e., without reliance on a prevailing practice, our holding in Ruzicka I will render the union liable for unfair representation.” Ruzicka II, supra, p 1212.
In essence, arbitrary conduct constituting a breach of the duty of fair representation is that "which reflects reckless disregard for the rights of the individual employee”. Id.
In Hoffman v Lonza, Inc, 658 F2d 519, 520 (CA 7, 1981), the Seventh Circuit held "that an action *673for breach of the duty to fairly represent requires more than a showing that the union failed to properly process the employee’s grievance”. In Hoffman, the union "forgot” to comply with collectively bargained grievance procedure time limits. The court, relying on dicta in Amalgamated Ass’n of Street, Electric Railway & Motorcoach Employees of America v Lockridge, 403 US 274, 299-300; 91 S Ct 1909; 29 L Ed 2d 473 (1971), reh den 404 US 874; 92 S Ct 24; 30 L Ed 2d 120 (1971), a case involving a pre-emption issue and, only marginally, alleged discriminatory conduct by the union, concluded that the United States Supreme Court requires a showing of intentional misconduct to make out a breach of the duty of fair representation due to arbitrary conduct. The court reached its conclusion on the basis of two policy factors: (1) to limit court interference with the subject of collective bargaining which is properly within the jurisdiction of the National Labor Relations Board,9 and (2) to reduce the possibility of collusion between unions and employees, "both of whom may share the same ultimate goal of reinstatement of the employee”. Hoffman, p 522. However, in reaching its conclusion, the court did not properly distinguish the three distinct standards of conduct which compose the duty of fair representation.
"The legal action based on the union’s duty to fairly represent might be more properly labeled as an action for the union intentionally causing harm to an employee involved in a grievance proceeding. The 'duty’ is not breached and the employee has no remedy without substantial evidence of fraud, deceitful action or dishon*674est conduct. * * * We must therefore part company with the Sixth Circuit, and hold that an action for failure to fairly represent cannot be based solely on an allegation that a union unintentionally failed to file a notice that would permit a grievance to proceed to arbitration.
"Mere negligence cannot rise to the level of misconduct necessary to support an action for breach of the Union’s duty of fair representation. Stating that the Union should have considered the merits of Hoffman’s grievance rather than permitting his claim to lapse by failing to file a timely notice of appeal does nothing more than describe the Union’s alleged negligence. It does not state a claim of arbitrary, discriminatory, or bad faith conduct.” Id., pp 522-523.
Concurring, Judge Cudahy criticized the majority’s reliance on Lockridge and argued that a breach of the duty of fair representation due to arbitrary conduct did not require an intentional act, but merely egregious behavior. To hold otherwise would render meaningless the "arbitrary” portion of Vaca’s tripartite standard of conduct. Id., pp 523-525 (Cudahy, J., concurring).
"Deference to union decisionmaking is essential to the purposes of the Vaca standard. But deference to a union’s failure to make a decision serves no valid union interest.” Id., p 525.
Finally, in Dutrisac, supra, p 724, the court concluded that
"an unintentional omission by a union representative amounts to a breach of the duty of fair representation when the omission reflects a reckless disregard for the rights of the employee, the omission severely prejudices the employee, and the policies underlying the duty of fair representation would not be served by shielding the union from liability in the circumstances of the particular case. Where these three elements are satisfied, the *675omission is classified as being so egregious, so far short of minimum standards of fairness to the employee and so unrelated to legitimate union interests as to be arbitrary.” Also Robesky v Qantas Empire Airways Ltd, 573 F2d 1082 (CA 9, 1978).
Further, after reviewing Ruzicka I, Ciirth, and Ruggirello, the court stated:
"[w]here there is no determination of the merits of an employee grievance and the union negligently misses a time limit resulting in depriving the employee of access to the mandatory grievance dispute process, the union has acted arbitrarily and so has breached its duty of fair representation. Where there has been a determination that a grievance is meritorious and the union negligently misses a time limit resulting in depriving the employee of access to the mandatory grievance dispute process, the union has acted arbitrarily and so has breached its duty of fair representation. Where there has been a determination that a grievance is meritorious and the union determines not to process the grievance based on rational, objective criteria, the union has not acted arbitrarily and so has not breached its duty of fair representation. And, of course, where the union determines that the grievance is not meritorious, and for whatever reason it is not processed, the union has not acted arbitrarily, and so has not breached its duty of fair representation.” Dutrisac, supra, pp 726-727.
Finally, the court concluded that the conduct of the union in the case before it did not amount to mere negligence which shielded the union from liability.
"[I]n the case of a terminated employee, the failure to comply with a time limit which is clear on its face, where a determination has been made that an employee grievance has some merit, and where the missing of the time limit has the effect of depriving an employee of the mandatory grievance procedures pro*676vided by the collective bargaining agreement between an employer and a union, is arbitrary conduct constituting a breach of the duty of fair representation, and no matter how innocently the time limit was missed, such conduct cannot constitute 'mere’ negligence.” Id., p 727.
B. Michigan Cases.
Since Lowe, supra, this Court has not definitively addressed the problem now before us.10 However, the Court of Appeals has had several opportunities to analyze the issue.
In Kennedy v UAW-AFL-CIO Local No 659, 3 Mich App 629, 632; 143 NW2d 133 (1966), the Court of Appeals implied in dicta that summary disposition would have been proper because the plaintiff alleged "no bad faith, arbitrary action or fraud on the part of the union in processing his grievance”. Also Field v Local 652 UAW AFL-CIO, 6 Mich App 140, 146-147; 148 NW2d 552 (1967).
The oft-stated maxim that "a union is not liable to a member for breach of its duty of fair representation for mere negligence” was repeated by the Court of Appeals in Sims v United Papermakers & Paperworkers AFL-CIO, 26 Mich App 129, 132; 182 NW2d 90 (1970). Although citing the three standards of conduct set down in Vaca, the Court of Appeals found them not to encompass the union’s failure to timely demand arbitration of the plaintiffs grievance. Accordingly, it was held that, since the complaint alleged only simple negligence, summary judgment should have been granted in favor of the union, i.e., the complaint did not state a claim for a breach of the duty of fair representation. Sims, supra, pp 132-135.
Conversely, in Handwerk v United Steelworkers *677 of America, 67 Mich App 747, 750-753; 242 NW2d 514 (1976), the Court of Appeals found that allegations regarding the union’s failure to timely demand arbitration pursuant to collectively bargained grievance procedure time limits did state a cause of action for a breach of the duty of fair representation due to arbitrary conduct so as to withstand a motion for summary judgment under GCR 1963, 117.2(1). The Court distinguished Sims as a pre-Lowe case. Thus, it relied not on Sims, but on Ruzicka I.
In Merdler v Detroit Bd of Ed, 77 Mich App 740, 746; 259 NW2d 211 (1977), the union did not process the plaintiffs grievance because it found the grievance to be without merit. The Court of Appeals, citing Handwerk, found that such conduct was not negligent. However, the Court of Appeals essentially held that the plaintiffs allegations of bad-faith conduct on the part of the union amounting to a breach of the duty of fair representation were conclusory and insufficient to state a claim. Thus, summary judgment under GCR 1963, 117.2(1) in favor of the union was proper. Merdler, supra, pp 745-747. Also Martin v Shiawassee County Bd of Comm’rs, 109 Mich App 32; 310 NW2d 896 (1981).
Similarly, in Pearl v Detroit, 126 Mich App 228, 235-238; 336 NW2d 899 (1983), the union did not demand arbitration of the plaintiffs grievance because it found the grievance to be without merit. The Court of Appeals held that the plaintiffs allegations of bad faith and discriminatory and arbitrary conduct on the part of the union amounting to a breach of the duty of fair representation were conclusory and, since the union had submitted affidavits and depositions showing that its conduct was proper which the plaintiff did not *678rebut, summary judgment under GCR 1963, 117.2(3) in favor of the union was appropriate.

We must decide, generally, what constitutes arbitrary union conduct amounting to a breach of the duty of fair representation, and, specifically, whether defendant union’s conduct in this case falls within that general definition. Initially, we think it clear that both the MERC and the Court of Appeals erred by requiring plaintiffs to show bad faith on the part of the union in order to establish a breach of the duty of fair representation due to arbitrary conduct. Indeed, the language of both Vaca and Lowe points out the error of the MERC and the Court of Appeals analyses.11
An examination of the words in question is in order. As Judge McCree noted in Ruzicka I, both "arbitrary” and "perfunctory” are adjectives indicating an intentional act or omission. A standard dictionary definition of "arbitrary” is "determined by whim or caprice”, while that of "perfunctory” is "done or acting routinely and with little interest or care”. Similarly, "whim” means "a sudden or capricious idea”, while "caprice” means "an impulsive change of mind”.
"The words 'arbitrary’ and 'capricious’ have generally accepted meanings. The United States Supreme Court has defined the terms as follows:
"Arbitrary is: ' "[WJithout adequate determining principle * * * Fixed or arrived at through an exercise of will or by caprice, without consideration or adjustment with reference to principles, circumstances, or significance, * * * decisive but unreasoned” ’.
"Capricious is: ' "[A]pt to change suddenly; freakish; whimsical; humorsome” ’.
*679 "United States v Carmack, 329 US 230, 243; 67 S Ct 252; 91 L Ed 209 (1946).” Bundo v City of Walled Lake, 395 Mich 679, 703, fn 17; 238 NW2d 154 (1976).
In contrast, "bad faith” indicates an intentional act or omission undertaken dishonestly or fraudulently. Arbitrary or perfunctory conduct does not require a dishonest or fraudulent intention for its accomplishment. Consequently, a union, through arbitrary conduct and absent any bad faith, can breach its duty of fair representation.
Further, for purposes of PERA, we do not interpret a union’s responsibility to avoid arbitrary conduct narrowly.12 In addition to prohibiting impulsive, irrational, or unreasoned conduct, the duty of fair representation also proscribes inept conduct undertaken with little care or with indifference to the interests of those affected. We think the latter proscription includes, but is not limited to, the following circumstances: (1) the failure to exercise discretion when that failure can reasonably be expected to have an adverse effect on any or all union members, and (2) extreme recklessness or gross negligence which can reasonably be expected to have an adverse effect on any or all union members. We hold that the conduct of defendant union in this case is encompassed by the foregoing prohibitions.
Testimony before the hearing referee indicated that the local union determined that plaintiffs’ grievances had merit and processed them through the first three steps of the collectively bargained grievance procedure. The local claimed to have then forwarded the grievances to the district council for further processing through the grievance mechanism. However, although it was the district’s practice to process all step-three grievances *680to step four, plaintiffs’ grievances were not timely processed to step four. The district could offer no reason for that failure, other than to claim that it never received the grievances from the local.
Although we agree with the maxim that a union’s mere negligence does not constitute a breach of its duty of fair representation, the conduct in this case amounted to much more. Indeed, the Sixth Circuit would find that the negligence was not ordinary because there was no reliance on a past practice. Ruzicka II; Ruzicka III. Rather, the failure to process the grievances to step four was directly contrary to the union’s past practice. Absent a reasoned, good-faith, nondiscriminatory decision not to process a grievance,13 if elected union officials fail to comply with collectively bargained grievance procedure time limits, the union has acted arbitrarily and breached its duty of fair representation. Union officials should certainly be aware of grievance procedure time limits which are included in an agreement which the union collectively bargained for on behalf of its members. Their inexplicable failure to comply with those limits indicates inept conduct undertaken with little care or with indifference to the interests of those affected, an extreme recklessness or gross negligence which could reasonably have been expected to have had an adverse effect on the griev-ants.
We adopt the following comments of the federal district court in Dutrisac, supra, p 728, as they are a fitting conclusion to this analysis:
"The Court wishes to point to two very compelling reasons that conduct such as that found in the present *681case should not constitute only 'mere* negligence. First, the collective bargaining agreement provides that only the union can file for arbitration on behalf of the employee with the- employer; the employee himself cannot file. This is a common provision in collective bargaining agreements. This provision, negotiated and entered into by the union and the employer, places an imposing duty upon the union to file notices of arbitration without mistake. With such a weighty duty, lesser conduct than is required in other circumstances can constitute arbitrary conduct violating the duty of fair representation owed to the employee-union member.
"Second, there is a severe loss to the employee where the union fails to observe a time limit such as the one in the present case. A terminated employee is prevented from pressing his grievance against the employer where the union has missed a time limit that must be complied with to invoke a stage of the mandatory grievance process. Thus, the employee is left with no recourse against the employer unless he can prove in court that the union violated its duty of fair representation. The severe loss to the employee of improper termination coupled with an inability to invoke a review of the employer’s decision imposes a weighty burden on the union not to make mistakes in the handling of the employee’s grievance. Again, lesser conduct can constitute arbitrary conduct and a breach of the duty of fair representation, because the duty of the union is great. If unions are allowed to escape breaches of the duty of fair representation by claiming that they only negligently missed time limits that precluded review of the employee’s termination, employees will never be able to pursue their claims of improper termination. This is a loss to the employee that this Court cannot tolerate.”
IV
In conclusion, we hold that: (1) PERA impliedly imposes on labor organizations representing public sector employees a duty of fair representation; (2) bad-faith conduct is not always required to make *682out a breach of that duty; (3) the conduct prohibited by the duty of fair representation includes (a) impulsive, irrational or unreasoned conduct, (b) inept conduct undertaken with little care or with indifference to the interests of those affected, (c) the failure to exercise discretion, and (d) extreme recklessness or gross negligence; (4) absent a reasoned, good-faith, nondiscriminatory decision not to process a grievance, the failure of a labor organization to comply with collectively bargained grievance procedure time limits constitutes a breach of the duty of fair representation; and (5) in this case, the union’s inexplicable failure to comply with the grievance procedure time limits indicates inept conduct undertaken with little care or with indifference to the interests of plaintiffs, which could have reasonably been expected to foreclose plaintiffs from pursuing their grievance further. As a result, the union breached its duty of fair representation to plaintiffs.
The judgments of the Court of Appeals and of the MERC are reversed, and this case is remanded to the MERC for a determination of the relief due plaintiffs.14
