This is an appeal from a Superior Court judgment affirming a Labor Relations Commission (commission) decision that held that Forbes Library violated the labor laws, G. L. c. 150A, §§ 3, 4 (1), 4 (3), when it dis
Richard Steward began work for the library in 1976. His supervisors were Glenda Henerey Donovan, head of the media department, and Stanley Greenberg, library direct- or. The final decision to fire Steward was made by the library’s three-member board of trustees, acting on the recommendations of the supervisors Donovan and Green-berg.
Problems between Steward and his supervisors began in the summer of 1977. Steward began to complain. about wages and work assignments, and met with other employees to discuss his complaints and solicit interest in unionization. He also retained an attorney to determine whether library workers were public employees. These activities were the subjects of a number of disputes between Steward and his supervisors.
In March, 1978, Steward arranged a meeting with one of the trustees, Katherine Finn, to present his complaints and proposals. This angered Greenberg, and relations deteriorated rapidly. Greenberg solicited letters of complaint about Steward from other employees, and he and Donovan met several times with the trustees to express their displeasure with Steward.
In May, the trustees held a meeting at which both sides aired their views. Donovan charged Steward with “subversive activities” and an inability to “accept authority.” Under these headings she listed several infractions of library rules,
In early June, the trustees voted two to one to discharge Steward. Steward subsequently filed a charge with the commission. The commission issued an unfair labor practice complaint, conducted a hearing, and concluded that the trustees had violated the labor laws. It ordered the trustees to reinstate Steward with back pay. A three-judge panel of the Superior Court affirmed, and the trustees have appealed. We transferred the case to this court on our own motion.
1. Standard of evaluation and burden of proof. The trustees first argue that the commission should have applied a “dual motive” standard in its evaluation of their decision. The commission dismissed the reasons offered by the trustees to explain their action as mere pretexts, and concluded that Steward had been discharged solely because he had engaged in activities protected by the labor laws. See G. L. c. 150A, §§ 3, 4 (1), 4 (3). The trustees point out that there was evidence of mixed motives — some lawful and some unlawful. They argue that the commission, in its single-motive analysis, gave inadequate consideration to the trustees’ asserted lawful motives.
We believe that the commission’s findings justify its decision under any of the standards argued by the parties; therefore, we need not choose among standards in order to resolve this case. We think it appropriate, however, to outline a standard and an accompanying burden of proof, so that the commission will have clear guidelines for its future decisions. We conclude that the commission should not reinstate an employee unless it finds that the employee would not have been discharged but for his protected activity. The burden of proof under this standard should follow
Courts in other jurisdictions have developed at least two standards for evaluating motivation when an employer accused of unlawful discharge claims to have had independent, lawful reasons to fire its employees. The first standard to appear was the “in part” test, which holds that the employer has violated the labor laws if it was motivated “even in part” by unlawful sentiments. See, e.g.,
NLRB
v.
Gogin,
A second standard used to resolve dual motive cases is the “dominant motive,” or “but for” test. If the employer would not have discharged the employee but for the employee’s protected activities, the discharge is unlawful and the employee must be reinstated. If, however, a lawful cause would have led the employer to the same conclusion even in the absence of protected conduct, the discharge must not be disturbed. E.g.,
NLRB
v.
Eastern Smelting & Ref. Corp.,
We prefer the “but for” standard. As the Supreme Court pointed out in an unlawful discharge case arising under the First Amendment, an “in part” test of motive is often overprotective.
Mt. Healthy City School Dist. Bd. of Educ.
v.
Doyle,
Having stated our preference for the “but for” standard, we now turn to the question of burden of proof. A “but for” standard calls for special attention to the burden of proof of unlawful motivation. Motivation is a subjective issue, seldom susceptible to direct proof. Moreover, a “but for” standard amplifies difficulties of proof, because the parties must address lawful as well as unlawful motives.
Courts that apply a “but for” test have varied in their allocations of the burden of proof. Some hold that the employee, or the labor commission as charging party, bears the entire burden of proof. The charging party must prove
The employee’s problems of proof could be alleviated by a rule placing the burden of persuasion on the employer; once the employee had established that the employer had an improper motive and that this motive contributed at least in part to the discharge, the burden would shift to the employer. To escape liability, the employer would then have to prove by a preponderance of evidence that other, lawful considerations would have led it to fire the employee in any event. See
NLRB
v.
Eastern Smelting & Ref. Corp.,
When an employer is charged with retaliation against union activity, however, such a complete shift may not be appropriate. The labor laws do not require an employer to have “just cause” to fire an employee. See
NLRB
v.
Eastern Smelting & Ref. Corp.,
Our cases in the area of sex discrimination suggest a third, intermediate method of allocating the burden of proof under a “but for” standard. See
School Comm. of Braintree
v.
Massachusetts Comm’n Against Discrimination,
This procedure lightens the employee’s burden; the employer’s evidence provides information and narrows the field of possible lawful reasons that the employee must address. It does not, however, go as far to relieve the employee’s burden as does the rule we have applied in bailee cases, which shifts the burden of persuasion to the party closest to the facts. The employer’s burden following a prima facie showing of sex discrimination is only a responsibility to produce evidence. Once the employer has proposed a reason and presented supporting facts, the presumption of discrimination is dispelled. See McCormick, Evidence §§ 336, 345 (2d ed. 1972). The employer need not persuade the trier that it was correct in its belief that the employee had broken rules, nor that the rules infractions would have caused it to discharge an employee of any sex. The burden of persuasion remains with the employee, who must prove by a preponderance of evidence that the asserted lawful reason was not the real reason for the discharge. School Comm. of Braintree, supra at 429. Smith College, supra at 230. Wheelock College, supra at 136-139. Thus, if the evidence is in balance, the employer must prevail. 5
2.
Review of the evidence.
We come now to the trustees’ second argument — that the commission’s decision was contrary to the evidence. Although this court is free to examine the legal standards employed by the commission, our power to review the commission’s findings of fact is circumscribed by the standards set out in the State Administrative Procedure Act. See G. L. c. 150A, § 6
(e), (f)
(incorporating G. L. c. 30A, § 14 [7]). Unless the commission’s findings are “[unsupported by substantial evidence,” we must affirm. G. L. c. 30A, § 14 (7)
(e),
as amended through St. 1973, c. 1114, § 3. “Substantial evidence” is evidence that “a reasonable mind might accept as adequate to support a conclusion.” G. L. c. 30A, § 1 (6), inserted by St. 1954, c. 681, § 1.
Labor Relations Comm’n
v.
University Hosp., Inc.,
There is ample evidence that Donovan and Greenberg were displeased with these activities, and that their displeasure motivated them to recommend that Steward be discharged. On several occasions, the supervisors directly expressed their hostility to Steward’s protected activities. Greenberg, in his letter recommending discharge, spoke of “actions more suitable to coal mines and factories.” Donovan, in her statement to the trustees, included Steward’s complaints about pay, his communications with other employees, and his investigation into public employee status under the heading “subversive activities.” The commission also points to various circumstantial evidence of unlawful motivation; for example, Donovan and Greenberg became abruptly more hostile after Steward met with trustee Finn to discuss pay, benefits, and improvements. Cf.
NLRB
v.
South Shore Hosp.,
This evidence, of course, concerns the sentiments of the supervisors rather than those of the trustees, who made the final decision. When persons responsible for discharging an employee have independent reasons for their decision, apart from the recommendations of lower level supervisors, the commission must give those reasons due consideration as motives for the discharge. If however, the decision makers relied on the recommendations of supervisors, the motives of the supervisors should be treated as the motives for the deci
The commission also addressed the crucial question under a “but for” standard — whether the lawful reasons asserted by the library actually served as independent motives in the decision. In a letter to Steward, the trustees stated three reasons for discharging him — failure to obey the supervisor, Donovan; failure to obey the department head, Greenberg; and failure to conform to library rules. They named no specific violations of rules, and the commission found that various violations cited by Donovan and Green-berg were trivial, false, or long-condoned. Donovan complained of attendance problems, but Greenberg had checked Steward’s time cards and found no irregular absences. Steward explained that equipment failure had caused him to close late several times after films. Steward also presented evidence that Greenberg had approved certain changes that he had made in the media department without Donovan’s permission. Further, although the infractions
The other reasons for the discharge, proposed by Donovan and Greenberg and adopted by the trustees, centered on the tension between Steward and his supervisors. Steward gave convincing evidence that these “authority” problems were triggered by his protected activities. The hostilities began when Steward began to speak to the supervisors and to fellow employees about pay, work conditions, and public employee status, and increased as Steward’s activities increased. Further, both Donovan’s and Greenberg’s written charges concerning Steward’s response to authority referred expressly to protected activities. Therefore, the commission could reasonably conclude that the “authority” reasons were indistinguishable from the supervisors’ retaliatory sentiments. An employee’s refusal to accept authority cannot be considered a lawful, independent reason for discharge when the authority in question was used to suppress protected activity. See
NLRB
v.
South Shore Hosp.,
In sum, we hold that employer motivation should be judged by a “but for” standard, and that the burden of proof should be allocated according to the procedure described in our sex discrimination cases. Further, we believe that the evidence supported the commission’s findings that unlawful considerations motivated the trustees’ decision to fire Steward, and that lawful considerations did not. It follows that the commission’s decision was justified under any of the “dual motive” standards it might have applied, including the standard that we have approved. Therefore, we affirm the judgment of the Superior Court.
So ordered.
Notes
General Laws c. 150A, § 3, outlines basic employee rights to self-organization, collective bargaining, and concerted activity for mutual aid and protection. Section 4 defines unfair labor practices by an employer. These include interference with the exercise of rights protected by § 3, and hiring and tenure practices that discriminate against or in favor of union membership. Section 6 empowers the Labor Relations Commission to conduct unfair practice hearings and to grant appropriate relief.
The cases cited were decided under the National Labor Relations Act, 29 U.S.C. §§ 151-169 (1976 & Supp. III 1979), which is analogous to our own labor laws in all material respects.
The United States Court of Appeals for the First Circuit has also expressed its standard as requiring the National Labor Relations Board to show “why the employer rejected the good cause and chose a bad one.”

v.
Labor Relations Comm’n,
To ensure that the commission against discrimination did not displace an employer’s legitimate business judgment, we stated in
Smith College, supra
at 230, 231-232, that an employee faced with an employer’s evidence of a lawful reason bears a burden of persuasion on two distinct points. We said that the employee must show that the reason was not supported by the facts, and that it was not an actual, independent force in the decision. In the
Smith College
case, the employer claimed that the
We do not endorse the commission’s conclusion that this was not a “dual motive” case. This case, like most cases in which an employee believes that his employer has discharged him for an unlawful reason, involves several possible motives. The employer has advanced legitimate reasons for the decision, and these reasons are entitled to consideration under a “dual motive” standard. However, the commission’s mistaken characterization of the case is not fatal to its decision, because its evaluation of the employer’s asserted reasons was equivalent to a dual motive analysis.
