but employers retain the right to discharge workers for any number of other reasons unrelated to the employee’s union activities.

Prior to his discharge, Sam Santillo was a busdriver for respondent Transportation Management Corp. On March 19, 1979, Santillo talked to officials of the Teamster’s Union about organizing the drivers who worked with him. Over
Later that evening Patterson talked to Ed West, who was also a busdriver for respondent. Patterson asked, “What’s with Sam and the Union?” Patterson said that he took Santillo’s actions personally, recounted several favors he had done for Santillo, and added that he would remember San-tillo’s activities when Santillo again asked for a favor. On Monday, March 26, Santillo was discharged. Patterson told Santillo that he was being fired for leaving his keys in the bus and taking unauthorized breaks.
Santillo filed a complaint with the Board alleging that he had been discharged because of his union activities, contrary to §§ 8(a)(1) and 8(a)(3) of the NLRA. The General Counsel issued a complaint. The Administrative Law Judge (ALJ) determined by a preponderance of the evidence that Patterson сlearly had an antiunion animus and that Santillo’s discharge was motivated by a desire to discourage union activities. The ALJ also found that the asserted reasons for the discharge could not withstand scrutiny. Patterson’s disapproval of Santillo’s practice of leaving his keys in the bus was clearly a pretext, for Patterson had not known about Santillo’s practice until after he had decided to discharge San-tillo; moreover, the practice of leaving keys in buses was commonplace among respondent’s employees. Respondent identified two types of unauthorized breaks, coffeebreaks and stops at home. With respect to both coffeebreaks and stopping at home, the ALJ found that Santillo was never cautioned or admonished about such behavior, and that the employer had not followed its customary practice of issuing three written warnings before discharging a driver. The

Wright Line,
Employees of an employer covered by the NLRA have the right to form, join, or assist labor organizations. NLRA § 7, 29 U. S. C. § 157. It is an unfair labor practice to interfere with, restrain, or coerce the exercise of those rights, NLRA
Under these provisions it is undisputed that if the employer fires an employeе for having engaged in union activities and has no other basis for the discharge, or if the reasons that he proffers are pretextual, the employer commits an unfair labor practice. He does not violate the NLRA, however, if any antiunion animus that he might have entertained did not contribute at all to an otherwise lawful discharge for good cause. Soon after the passage of the Act, the Board held that it was an unfаir labor practice for an employer to discharge a worker where antiunion animus actually contributed to the discharge decision.

At the same time, there were decisions indicating that the presence of an antiunion motivation in a discharge case was not the end of the matter. An employer could escape the consequences of a violation by proving that without regard to the impermissible motivation, the employer would have taken the same action for wholly permissible reasons.

As we understand the Board’s decisions, they have consistently held that the unfair labor practice consists of a discharge or other adverse action that is based in whole or in part on antiunion animus — or as the Board now puts it, that the employee’s protected conduct was a substantial or motivating factor in the adverse action. The General Counsel has the burden of proving these elements under § 10(c). But the Board’s construction of the statute permits an employer to avoid being adjudicated a violator by showing what his actions would have been regardless of his forbidden motivation. It extends to the employer what the Board considers to be an affirmative defense but does not change or add to the elements of the unfair labor practice that the General Counsel has the burden of proving under § 10(c).

The Board was justified in this case in concluding that Santillo would not have been discharged had the employer not considered his efforts to establish a union. At least two of the transgressions that purportedly would have in any event prompted Santillo’s discharge were commonplace, and yet no transgressor had ever before received any kind of discipline. Moreover, the employer departed from its usual practice in dealing with rules infractions; indeed, not only did the employer not warn Santillo that his actions would result in bеing subjected to discipline, it also never even expressed its disapproval of his conduct. In addition, Patterson, the person who made the initial decision to discharge Santillo, was obviously upset with Santillo for engaging in such protected
Accordingly, the judgment is
Reversed.
Notes
Section 8(a), as set forth in 29 U. S. C. § 158(a), provides, in relevant part:
“It shall be an unfair labor practice for an employer—
“(1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 157 of this title;
“(3) by discrimination in regard to hire or tenure of employment or any term or condition of employment to encourage or discourage membership in any labor organization . . . .”
Section 10(c) provides, in relevant part:
“If upon the preponderance of the testimony taken the Board shall be of the opinion that any person named in the complaint has engaged in or is engaging in any such unfair labor practice, then the Board shall state its findings of fact and shall issue and cause to be served on such person an order requiring such person to cease and desist from such unfair labor practice, and to take such affirmative action including reinstatement of employees with or withоut back pay, as will effectuate the policies of this subchapter .... If upon the preponderance of the testimony taken the Board shall not be of the opinion that the person named in the complaint has engaged in or is engaging in any such unfair labor practice, then the Board shall state its findings of fact and shall issue an order dismissing the said complaint. No order of the Board shall require the reinstatement of any individual as an employee who has been suspended or discharged, or the payment to him of any back pay, if such individual was suspended or discharged for cause.” 29 U. S. C. § 160(c).
The Board’s

v.
New York University Medical Center,
The Board argues that its approach to mixed-motive cases was known to Congress and ratified by thе passage of the Labor Management Relations Act (LMRA), 61 Stat. 136, which reenacted §§ 8(a)(1) and 8(a)(3) almost without material change. We need not pass on this submission, since we find nothing in the legislative history of the LMRA that calls into question the decisions of the Board relevant to the issue before us now. The issue after, as well as before, the passage of the LMRA is whether the Board’s construction of § 8(a) is sufficiently rational to be acceptable in the courts. We do note that nowhere in the legislative history is reference made to any of the mixed-motive cases decided by the Board or by the courts, see,
e. g., NLRB

Thе Board has not purported to shift the burden of persuasion on the question of whether the employer fired Santillo at least in part because he engaged in protected activities. The General Counsel satisfied his burden in this respect and no one disputes it. Thus,

v.
Burdine,
The language of the NLRA requiring that the Board act on a preponderance of the testimony taken was added by the LMRA, 61 Stat. 136, in 1947. A closely related provision dirеcted that no order of the Board reinstate or compensate any employee who was fired for cause. Section 10(c) places the burden on the General Counsel only to prove the unfair labor practice, not to disprove an affirmative defense. Furthermore, it is clear
The “for cause” proviso was not meаnt to apply to cases in which both legitimate and illegitimate causes contributed to the discharge, see infra. The amendment was sparked by a concern over the Board’s perceived practice of inferring from the fact that someone was active in a union that he was fired because of antiunion animus even though the worker had been guilty of gross misconduct. The House Report explained the change in the following terms:
“A third change forbids the Board to reinstate an individual unless the weight of the evidence shows that the individual was not suspended or discharged for cause. In the past, the Board, admitting that an employee was guilty of gross misconduct, nevertheless frequently reinstated him, ‘inferring’ that, because he was a member or an official of a union, this, not his misconduct, was the reason for his discharge.” H. R. Rep. No. 245, 80th Cong., 1st Sess., 42 (1947) (emphasis added).
The provisо was thus a reaction to the Board’s readiness to infer antiunion animus from the fact that the discharged person was active in the union, and thus has little to do with the situation in which the Board has soundly concluded that the employer had an antiunion animus and that such feelings played a role in a worker’s discharge.
Respondent also argues that placement of the burden of persuasion on the employer contravenes § 10(b) оf the Act and § 7(c) of the Administrative Procedure Act, 5 U. S. C. § 556(d). Section 10(b) provides that the Federal Rules of Evidence apply to Board proceedings insofar as practicable. Respondent contends that Federal Rule of Evidence 301 requires
“In all civil actions and proceedings not otherwise provided for by Act of Congress or by these rules, a рresumption imposes on the party against whom it is directed the burden of going forward with evidence to rebut or meet the presumption, but does not shift to such party the burden of proof in the sense of the risk of nonpersuasion, which remains throughout the trial upon the party on whom it was originally cast.”
The Rule merely defines the term “presumption.” It in no way restricts the authority of a court or an agency to change the customary burdеns of persuasion in a manner that otherwise would be permissible. Indeed, were respondent correct, we could not have assigned to the defendant the burden of persuasion on one issue in

Section 7(c) of the Administrative Procedure Act, 5 U. S. C. § 556(d), provides that the proponent of an order has the burden of proof. Since the General Counsel is the proponent of the order, asserts respondent, the General Counsel must bear the burden of proof. Section 7(c), however, determines only the burden of going forward, not the burden of persuasion.
