Facts

The Board reversed an administrative law judge and found that supervisor Zamora threatened and coercively interrogated employees during a union organizing campaign, and that Penasquitos unlawfully discharged employees Rios and Martinez because of union activity. The administrative law judge had instead credited Zamora's testimony, found key employee testimony equivocal or fabricated, and concluded that the conversations were not coercive and the discharges were motivated by poor work performance. The discharge episode arose after Zamora observed Rios and Martinez working slowly and watching women sunbathe, and Martinez admitted he was working at a slow pace on the day he was fired. The Board relied in part on alleged anti-union statements, the abruptness and timing of the discharges, and evidence that union organizing was underway.

Issue

When the NLRB rejects an administrative law judge's credibility-based factual findings, may the Board's contrary findings be enforced where they rest largely on testimony the administrative law judge discredited or on weak inferences? Also, did the record as a whole contain substantial evidence that Penasquitos committed § 8(a)(1) and § 8(a)(3) violations?

Rule

Under NLRA § 10(e)-(f), courts treat Board factfinding as conclusive only if supported by substantial evidence on the record considered as a whole, and the administrative law judge's findings are part of that whole record. When the Board rejects an administrative law judge's credibility determinations based on witness demeanor, the supporting evidence must be stronger, because testimony discredited by the administrative law judge has severely reduced probative weight; by contrast, the Board is owed deference in drawing derivative inferences from not discredited evidence within its labor expertise. Employer interrogation is not per se unlawful; the test is whether, under all the circumstances, the questioning reasonably tends to restrain or interfere with employees' protected rights.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

At a hearing in Phoenix, an administrative law judge found that warehouse employee Leo Marin was not credible after observing his evasive testimony and inconsistent answers. The National Labor Relations Board nevertheless found that Leo's employer had threatened employees with discharge for supporting a union, relying only on Leo's account of a single conversation and no other credited evidence.

If the employer petitions for review, which result is most consistent with the governing doctrine?

Explanation. Courts defer to Board factfinding only if supported by substantial evidence on the record considered as a whole, and the ALJ's findings are part of that whole record. When the Board rejects demeanor-based credibility findings and relies solely on testimony the ALJ discredited, that testimony has severely reduced probative weight. Under the majority opinion, enforcement would likely be denied.
