Confidential Employees Under the NLRA: Labor Nexus Test and Exclusions

Under the National Labor Relations Act, a confidential employee is a worker who assists a manager involved in shaping the employer’s labor relations strategy and who, as part of that job, sees non-public labor relations information before it reaches the workforce or a union. The label doesn’t come from the statute itself. It comes from decades of National Labor Relations Board decisions applying what’s known as the labor nexus test, an approach the Supreme Court upheld in 1981. The practical consequence is significant: employees who meet the test are excluded from collective bargaining units and cannot vote in union representation elections.

The Labor Nexus Test

The NLRA, at 29 U.S.C. § 152, defines “employee” broadly and never uses the phrase “confidential employee.”¹ The Board filled the gap in its 1956 B.F. Goodrich decision, committing to exclude from bargaining units “persons who assist and act in a confidential capacity to persons who formulate, determine, and effectuate management policies in the field of labor relations.”²

In NLRB v. Hendricks County Rural Electric Membership Corp., the Supreme Court found a “reasonable basis in law” for that practice and rejected the broader argument that anyone with access to any confidential business information should fall outside the Act.³ That distinction is the whole point. The test is about labor relations information specifically, not business secrets generally.

Two connected requirements have to be met. The employee must work in a confidential capacity for someone who shapes the employer’s labor relations policies. And that work must give the employee advance access to non-public labor relations information. Both elements. An employee close to a labor relations executive who never handles sensitive bargaining material doesn’t qualify. Neither does a clerk who happens across a labor document but reports to someone with no role in labor strategy.

Who Counts as a Labor Relations Policy Formulator

The test hinges on what your supervisor actually does, not on their title. For the confidential label to stick, the supervisor has to formulate, determine, or carry out the organization’s labor relations policies. That means real decision-making authority over collective bargaining positions, grievance strategy, or company-wide labor standards.

A department manager who runs daily operations but has no say in how the company approaches union negotiations doesn’t count. The Board looks for evidence that the supervisor actively shapes the employer’s labor relations stance, whether by drafting bargaining proposals, deciding how to handle grievances, or setting the direction for dealings with labor organizations.⁴ If the manager doesn’t have that authority, people reporting to that manager won’t be classified as confidential no matter how sensitive their other work is.

The Board also considers whether someone “effectuates” labor policy, meaning they implement decisions made higher up. A human resources director carrying out bargaining strategy set by the CEO still qualifies as a policy formulator for these purposes. A mid-level supervisor simply following a handbook someone else wrote generally does not.

What Kind of Information Qualifies

The type of material the employee handles matters as much as who they report to. The Board’s Hearing Officer’s Guide identifies what counts: bargaining proposals, minutes from meetings where bargaining strategy is discussed, grievance investigation reports, and internal policy documents about grievance handling.⁵ The employee has to see this material before it reaches any union or the general workforce.

This is where a lot of employers overreach. Many assume that any worker touching sensitive business data (trade secrets, financial projections, customer lists, patent applications) qualifies. The Board has consistently rejected that view. An employee who handles proprietary business information but never sees labor relations material is not a confidential employee under the NLRA.² The Hendricks Court made this explicit, refusing to extend the exclusion to all employees with access to confidential information of any kind.³

Personnel and Payroll Records Are Not Enough

Access to personnel files, payroll records, or internal disciplinary actions does not by itself trigger the confidential designation. In Carling Brewing Co., the Board found that a clerk who routinely referenced personnel records and the terms of a collective bargaining agreement was not confidential because the clerk “takes no part in labor negotiations or grievance procedures.”⁶ An employee who overhears labor relations conversations doesn’t qualify either. The access has to be part of the employee’s regular duties, not incidental.

The 10 Percent Threshold

Even employees who do touch some labor relations material aren’t automatically excluded. The Board has historically declined to classify personal secretaries to management as confidential when they spend 10 percent or less of their time on industrial relations work.⁶ A secretary who occasionally types a bargaining memo but spends most of the day on general administrative work would likely remain eligible for bargaining unit inclusion.

Positions That Usually Qualify and Positions That Don’t

The roles most commonly classified as confidential are administrative assistants and secretaries directly supporting executives responsible for labor relations, labor relations or HR staff who prepare bargaining materials, and employees who regularly attend management strategy sessions about union negotiations. The common thread is direct, routine involvement in the employer’s labor relations decision-making.

Positions that typically fall outside the classification include payroll clerks, general HR assistants who process benefits paperwork but don’t touch bargaining strategy, IT employees with system-wide file access, and executive assistants whose bosses handle finance or operations rather than labor relations. The Board evaluates each case individually based on actual job duties, not job descriptions or organizational charts. An employer can’t simply label a position “confidential” and strip the worker of bargaining rights.

Employees who regularly substitute for a confidential employee may themselves be classified as confidential, depending on how often the substitution happens and how much labor relations material they see during those periods.

What the Classification Actually Costs You

The immediate consequence is exclusion from any collective bargaining unit. Confidential employees cannot vote in union representation elections and cannot be represented by a union for purposes of collective bargaining. The Board treats this as a policy matter, rooted in the concern that management “ought not to be placed in the untenable position of bargaining with employees who have advance knowledge of labor matters.”² The logic is simple. If the employee preparing the company’s bargaining proposals also sits in the union across the table, the employer’s position is compromised.

The Unresolved Question of Broader Section 7 Rights

Whether confidential employees lose all NLRA protections or only bargaining unit membership has never been fully settled. The Board’s own position, upheld in Hendricks, is that confidential employees remain “employees” under Section 2(3) of the Act. The Court noted that for more than 40 years the Board had declined to create “any implied exclusion from the definition of ’employee’ for confidential employees” and had applied the labor nexus test only for bargaining unit composition.³

Some federal appeals courts have gone further. The Fourth Circuit held that confidential secretaries were effectively unprotected by the Act, meaning their employer could lawfully discharge them for engaging in concerted activity like refusing to cross a picket line.⁶ The takeaway is worth remembering if you’re classified as confidential and thinking about any form of collective action with coworkers. You definitely can’t join a bargaining unit. Whether you retain other Section 7 rights, such as participating in concerted activity for mutual aid and protection, depends on which circuit you’re in.

Challenging a Confidential Classification

If a union or employer thinks a position has been misclassified, either side can file a unit clarification petition with the NLRB. Under 29 CFR § 102.60(b), these petitions are filed with the Regional Director for the region where the bargaining unit exists. The petition has to be in writing, signed, and sworn or declared under penalty of perjury, with a copy served on all parties named.⁷

At a hearing, the Board examines actual duties, not titles. According to the Hearing Officer’s Guide, the key lines of inquiry include the employee’s specific daily work, whether the supervisor handles labor relations like bargaining or grievance processing, and what type of confidential material the employee actually handles. The hearing officer also looks at whether the employee attends management meetings about labor strategy, how often they access labor relations documents, and whether they see that material before any union or rank-and-file employees do.⁵

When the Board finds that an employer wrongly excluded someone from a bargaining unit, the standard remedy is to make the employee whole. If the misclassification led to an unfair labor practice, such as firing an employee for union activity on the theory that they were confidential, the typical Board remedy includes reinstatement with back pay.²

What the Classification Does Not Change

Being classified as confidential under the NLRA affects collective bargaining rights only. It does not strip away protections under other federal employment statutes. Confidential employees remain covered by the Fair Labor Standards Act’s minimum wage and overtime rules, Title VII’s prohibition on discrimination, the Americans with Disabilities Act, and other workplace protections tied to the employment relationship rather than union status.

One source of confusion is the FLSA’s administrative exemption from overtime, which requires that an employee earn at least $684 per week on a salary basis, perform office work related to management or business operations, and exercise discretion on significant matters.⁸ That’s a separate analysis from the NLRA’s confidential employee test. An executive assistant classified as confidential for labor law purposes might still be entitled to overtime under the FLSA, and the reverse is equally possible. The two frameworks serve different purposes and use different criteria.
