Can employers monitor employees for union activity?

Can employers monitor employees for union activity? The U.S. Court of Appeals for the Fifth Circuit answered that question with a narrower standard on Sept. 4, largely refusing to enforce a National Labor Relations Board order that had found Starbucks committed multiple unfair‑labor practices tied to union organizing in Kansas and Buffalo. The court reversed or remanded most of the board’s findings that the company created an impression of surveillance or unlawfully threatened employees, while upholding a single finding that a manager threatened to deny maternity‑leave benefits.

The decision, issued Sept. 4, 2026, concerns NLRB regional rulings tied to union campaigns at Starbucks stores in Kansas and Buffalo. In its opinion the Fifth Circuit concluded the board’s conclusions about surveillance and threats were not supported by the record in most instances and sent several issues back for further consideration or reversed them outright. The court left intact the board’s determination that a manager had unlawfully threatened to deny maternity benefits, preserving that narrower violation.

Starbucks has argued throughout the litigation that its ordinary store procedures and use of electronic systems — including badge logs and scheduling tools — were being mischaracterised as surveillance designed to chill union activity. The NLRB, in its original decision, found that certain managerial statements, badge‑scan practices and store monitoring created an objective impression of surveillance and, in some cases, unlawful coercion. The Fifth Circuit disagreed on most points, saying the board’s inferences exceeded what the evidentiary record supported and remanding where factual findings needed clarification.

Labor lawyers said the ruling changes the calculus for both employers and unions. For employers, the decision reduces the near‑automatic weight previously given to employee testimony about feeling watched when managers refer to performance metrics or when stores use electronic access and attendance systems. For unions, the opinion tightens the evidentiary burden required to show that routine electronic systems or benign managerial remarks amount to unlawful surveillance or threats.

The case sits against a wider backdrop of rapidly proliferating electronic monitoring in retail and service workplaces. Companies increasingly rely on badge systems, scheduling algorithms, point‑of‑sale data and productivity scoring to run operations; courts and labor regulators have been wrestling with how traditional labor‑law doctrines apply when the “surveillance” is algorithmic or embedded in routine technology. The Fifth Circuit’s opinion signals that, at least in its jurisdiction, courts will scrutinize the factual basis for inferring coercive intent from digital records and manager comments rather than defer to broad board conclusions.

What the opinion did not resolve is equally important. The Fifth Circuit did not announce a bright‑line rule about when automated or electronic monitoring becomes unlawful under the National Labor Relations Act, and it left several factual findings to be revisited by the board. The ruling also does not parse whether particular classes of algorithmic tools — for example, predictive scheduling software or algorithmic task assignment — automatically create an objective impression of surveillance. Nor did the court lay out a uniform approach to assessing employee perceptions of monitoring across different workplaces.

Practically, human‑resources leaders and legal teams should view the decision as a prompt to revisit how monitoring tools are documented and justified. Employers that use electronic tracking will want clearer contemporaneous records explaining legitimate business purposes, training materials for managers on what can be said about performance, and a tighter factual record to defend routine practices. Unions and employees, meanwhile, may focus future complaints on explicit threats and documentary evidence rather than subjective impressions of being watched.

The narrower enforcement posture from the Fifth Circuit is likely to shape how similar cases proceed — whether in further administrative proceedings, in other federal circuits, or if the NLRB seeks rehearing or Supreme Court review. For HR leaders wrestling with the legal risks of workplace monitoring, the decision underscores that technological surveillance raises questions that will be decided case‑by‑case, and that precise factual proof — not broad policy arguments — will often determine the outcome.
