ACLU: Protected Complaints and a Same-Decision Defense Led to a Divided Ruling

When management calls your workplace complaints “hostile,” it can be hard to know whether speaking up put your job at risk or whether the dispute turns on something else. In American Civil Liberties Union, Inc., 375 NLRB No. 67 (Oct. 30, 2026), the National Labor Relations Board dismissed a complaint challenging a discharge and a paused transfer. The majority accepted that one group discussion was protected, but found the employer would have discharged the employee even without it. Member Prouty dissented. The result reversed the attached judge’s contrary findings.

The history included shared complaints, employer responses and later conflict

Katherine Oh worked in the ACLU’s National Political Advocacy Department from 2017 until her May 2022 discharge. She and coworkers raised concerns about management, working conditions and treatment within the department. The employer responded through human resources, coaching and an outside investigation, and Oh received promotions. These facts mattered differently to the majority and dissent: The majority emphasized earlier employer responsiveness; the dissent treated the later events as part of a continuing history of collective concerns.

The majority concentrated on four events in 2022. A February organization-wide online discussion included Oh’s questions about trust in management. In March, she described being afraid of a supervisor and accused another manager of lying about the origins of a work assignment. In April, after counseling about her conduct and word choices, she posted two personal-account tweets criticizing bosses and a work initiative. The majority’s account appears in ACLU and continues through the third page.

The employer described a pattern of insubordination and hostility toward Black male colleagues. Those were its disciplinary explanations, not a reason to recast every workplace complaint as harassment. The outside investigator’s account in the attached judge’s decision found a damaging departmental culture while not finding that the earlier manager’s conduct was sexist or misogynistic. The parties’ allegations, the investigation and the Board’s labor-law findings require separate attribution.

Acting together and seeking a shared workplace benefit are distinct questions

The majority distinguished how employees act together from whether their activity seeks mutual aid or protection. It applied Meyers Industries, 268 NLRB 493, 497 (1984), and 281 NLRB 882, 886–887 (1986), on concerted activity, and Fresh & Easy Neighborhood Market, 361 NLRB 151, 152–153 (2014), on that distinction. The explanation appears in ACLU.

The March statements occurred in an individual meeting. The majority found no evidence that coworkers shared those particular concerns or that Oh was preparing or initiating group action through them. It also found the April tweets concerned her individual disagreement over a business initiative. Coworker followers and plural words such as “we” and “our” did not persuade it otherwise. Its footnote corrected the judge’s assumption about two likes: The record did not establish that those followers were coworkers.

The February discussion was different. It occurred in a group forum and followed employee concerns about management. The majority found that Oh’s comments were concerted and for mutual aid or protection. Because the employer partly relied on them, the General Counsel made the initial showing of unlawful motivation. That conclusion appears in ACLU. The dismissal therefore cannot be explained simply as an absence of protected activity.

The majority accepted a separate reason for the discharge

Under Wright Line, 251 NLRB 1083 (1980), once the required initial showing is made, the employer must prove it would have taken the same action without the protected activity. The majority applied that burden to the employer’s treatment of the March conduct, the April counseling and the tweets posted the next day. It found the later conduct supplied the same-decision defense. The framework begins in ACLU and the application appears on the fifth and sixth pages.

This was an evidence-based defense, rather than a conclusion that a “hostility” label defeats a claim. The majority treated the March statements and April tweets as unprotected in the circumstances it identified. It also expressly found it unnecessary to decide whether the February “beatings” comment lost protection because of its manner: The same-decision defense resolved the discharge allegation even assuming the comment remained protected. That actual boundary appears in the fourth footnote in ACLU.

The dissent read the full history and defense differently

Member Prouty would have affirmed the judge’s retaliation findings. He argued that the majority artificially separated the four events from years of shared complaints and overlooked evidence that coworkers had questioned the same initiative and workload. He viewed the later statements and tweets as a logical outgrowth of collective concerns, rather than isolated personal disagreements. The dissent develops that account in ACLU through the twelfth page.

The dissent also disputed whether the employer had proved the same-decision defense, criticizing the majority’s construction of an explanation from the record. The majority responded that the employer had maintained the relevant reasons throughout. Their disagreement concerned both classification of the employee’s conduct and the adequacy of the defense evidence. The dissent’s analysis begins in ACLU and continues on the next page. It is important reasoning to understand, while the majority’s dismissal remains the Board’s operative decision.

The transfer allegation and final order must be read separately

The majority rejected the transfer allegation because it found the relevant March statement was not concerted. It also addressed the alternative assumption that the statement was protected and partly motivated the pause. On that assumption, it accepted evidence of a new, orderly transfer process as a legitimate reason the transfer still would have been paused. Prouty read the timing and communications differently. The competing analyses appear in ACLU and in the dissent’s discussion beginning on the fourteenth page.

The Board dismissed the complaint. The reinstatement, backpay and notice language in the attached judge’s recommended order was not the operative relief after reversal. The attachment also contains the judge’s separate rejection of a pre-discharge bargaining allegation. Reading the majority’s order before the attachment prevents the older recommended remedy from being mistaken for the result.

The useful comparison is the actual complaint and the actual reason

For another worker, identify what was said, its connection to coworkers’ concerns, what management knew and which later conduct the employer actually relied on. Keep favorable and unfavorable communications together. Our guide to complaints labeled hostile or insubordinate develops that practical review. This decision applies federal labor law; discrimination, wage and other protections require their own coverage and legal analysis. A policy label or an isolated sentence does not replace that work.
