This National Labor Relations Board (NLRB) decision, Wright Line, a Division of Wright Line, Inc. and Bernard R. Lamoureux, addresses an alleged violation of Section 8(a)(3) and (1) of the National Labor Relations Act (the Act) stemming from the discharge of employee Bernard Lamoureux.

The Administrative Law Judge (ALJ) Lowell Goerlich had previously found that Wright Line violated the Act by discharging Lamoureux on December 30, 1977. The Respondent, Wright Line, filed exceptions to the ALJ's decision, challenging the credibility findings, factual conclusions, and the broad cease-and-desist order. The General Counsel filed a brief supporting the ALJ's decision.

The NLRB affirmed the ALJ's findings of fact and conclusions of law, agreeing that Lamoureux's discharge constituted an unfair labor practice. However, the Board modified the ALJ's recommended order by narrowing the scope of the cease-and-desist provision, as the violations in this case did not demonstrate a proclivity for unlawful conduct or egregious misconduct warranting a broad order.

The central legal issue before the Board was the appropriate test for determining causality in "dual motive" cases, where an employer's decision to discipline or discharge an employee is influenced by both legitimate business reasons and unlawful considerations, such as protected union activity. The Board acknowledged the confusion and inconsistency among various circuit courts and the Board itself regarding this issue.

To address this, the Board formally adopted the Mt. Healthy test of causation, drawing from the Supreme Court's decision in Mt. Healthy City School District Board of Education v. Doyle. The Board explained that this test would provide a uniform and clear framework for analyzing dual-motive cases, accommodating conflicting interests and promoting the Act's objectives.

The Mt. Healthy test is a two-part analysis: 1. Prima Facie Case: The General Counsel must first establish a prima facie showing that protected conduct was a "motivating factor" in the employer's decision. 2. Shifting Burden: Once the prima facie case is established, the burden shifts to the employer to demonstrate, by a preponderance of the evidence, that it would have taken the same action even in the absence of the protected conduct.

The Board clarified that this test is consistent with prior NLRB precedent, legislative history of Section 10(c) of the Act (which places the burden on the employer to prove an employee was discharged for cause), and Supreme Court decisions like NLRB v. Great Dane Trailers, Inc., which also support the employer bearing the burden of proof for legitimate business justifications. The Board explicitly rejected the prior "in part" test, which it found could place employees in a better position than if they had done nothing, and the "dominant motive" test, which improperly placed the burden of proof on the General Counsel to rebut the employer's defense.

Applying the Mt. Healthy test to the facts, the Board found that the General Counsel had presented a prima facie case that Lamoureux's union activity was a motivating factor in his discharge. This was supported by evidence of Respondent's union animus, including disparaging remarks directed at Lamoureux and the timing of his discharge shortly after a union election. Furthermore, the General Counsel showed that Respondent departed from its usual practice of not discharging employees for similar infractions, especially given Lamoureux's strong work record and the fact that his timesheet discrepancies caused no financial loss or detriment to the Respondent's production control system.

The Board then concluded that Wright Line failed to meet its burden under the Mt. Healthy test. The company's asserted justification—falsifying production time reports—was found to be pretextual and not the true reason for Lamoureux's discharge. The Board noted that the supposed inaccuracies were minor, common, and generally not grounds for discharge, and that more serious infractions by other employees had resulted in lesser discipline. The Board also highlighted that Lamoureux's final check was prepared before he was even confronted with the allegations, suggesting a predetermined decision to discharge him.

The Board therefore agreed with the ALJ's conclusion that Wright Line violated Section 8(a)(3) and (1) by discharging Bernard Lamoureux. The Order required Wright Line to offer Lamoureux immediate reinstatement, make him whole for lost earnings with interest, and post a notice to employees. The cease-and-desist order was modified to be "in any like or related manner" to prevent future violations, rather than a broad prohibition.

Member Jenkins concurred, expressing his willingness to apply the Mt. Healthy test but noting a reservation that in exceptionally complex mixed-motive cases, the "in part" standard might still be more appropriate to ensure that unlawful motives are not overlooked.
