Understanding the More Employer-friendly Standards for Privacy and Confidentiality Under the NLRB

The National Labor Relations Board's approach to employer workplace confidentiality policies has shifted significantly over time, with the pendulum swinging between employee-protective standards that restrict employer policy language and more employer-friendly approaches that give greater deference to legitimate business interests. Under the Boeing Company framework adopted during the Trump administration's NLRB, work rules and policies were evaluated under a categorical approach that classified them based on their potential impact on Section 7 rights—employees' rights to engage in protected concerted activity—and the employer's legitimate justification for the rule. This framework was generally more permissive of facially neutral policies that could theoretically chill Section 7 rights if the employer had a legitimate, non-pretextual reason for the policy. Policies covering workplace confidentiality, social media conduct, employee communications with media, and investigation confidentiality were evaluated under this more structured and predictable standard. The subsequent Stericycle decision under the Biden-era NLRB returned to a more employee-protective standard. HR professionals must monitor NLRB guidance closely as standards shift with administration changes. Aurora Training Advantage's HR webinars help professionals design confidentiality policies that navigate the evolving NLRB landscape while protecting legitimate business interests.

Under Section 7 of the National Labor Relations Act (NLRA), employees have the explicit right to discuss wages, hours, and working conditions with each other as protected concerted activity—and this right applies to virtually all private sector employees, whether unionized or not. Employer policies that broadly prohibit employees from discussing salaries, compensation, or benefits with coworkers are unlawful under the NLRA, and the NLRB has consistently struck down such policies as unlawful interference with Section 7 rights. This applies even if an employer's intent was simply to maintain internal confidentiality or prevent workplace conflict, not to suppress union organizing. However, employers can lawfully maintain policies that prohibit disclosure of confidential business information—such as customer data, trade secrets, or third-party financial information—provided those policies are narrowly tailored and clearly distinguished from prohibitions on employee discussions of their own employment terms. Policies that inadvertently sweep in wage discussions by using broad confidentiality language without carve-outs for Section 7 activity are vulnerable to NLRB challenge. HR professionals should review all employee handbook provisions related to confidentiality, social media, and internal communications to ensure they do not impermissibly restrict employees' right to discuss compensation. Aurora Training Advantage's HR compliance webinars provide guidance on navigating NLRA requirements in employment policy design.

The NLRB has addressed employer confidentiality requirements during workplace investigations in a series of rulings that create important limitations on how broadly employers can instruct employees to keep investigation details confidential. Historically, blanket instructions to employees interviewed in investigations—telling them not to discuss the matter with anyone—were found to be unlawful as categorical restrictions on Section 7 rights. The NLRB's approach has required employers to demonstrate a legitimate, particularized business justification for confidentiality in each specific investigation, such as protecting witnesses from retaliation, preventing evidence destruction, or preventing collusion among potential witnesses. Simply protecting the integrity of the investigation in general terms has been found insufficient in employee-protective eras of NLRB precedent, while more employer-friendly standards give greater weight to these general business justifications. Practically, HR professionals conducting workplace investigations should avoid issuing blanket confidentiality instructions without a specific, documented rationale, consider using time-limited confidentiality requirements tied to the active investigation period, and consult employment counsel on the current NLRB standard when designing investigation protocols. Post-investigation confidentiality regarding findings and disciplinary decisions is generally more defensible than restricting employee testimony during the investigation itself. Aurora Training Advantage's HR training programs help professionals design legally compliant investigation procedures.

Despite the protections that Section 7 of the NLRA affords employees, employers retain the right to maintain a wide range of legitimate workplace policies that serve genuine business interests, provided those policies do not unreasonably restrict employees' rights to engage in protected concerted activity. Policies that are generally permissible include those requiring respectful, professional conduct in the workplace—provided they do not prohibit criticism of working conditions or employer decisions. Policies protecting confidential customer data, trade secrets, proprietary business information, and third-party financial records are lawful when clearly distinguished from restrictions on employee discussion of their own employment terms. Social media policies may lawfully require employees to identify personal posts as their own opinion and not to disclose legally protected confidential information, but cannot broadly prohibit employees from discussing working conditions online. Policies against disparaging the company may be challenged if they could be read to prohibit organizing activity or protected criticism. No-solicitation and no-distribution policies are lawful if applied consistently and do not single out union-related activity. Anti-harassment policies that prohibit conduct that is genuinely harassing as opposed to merely critical are generally upheld. Aurora Training Advantage's HR compliance webinars help professionals audit their employee handbook policies against current NLRB standards and make targeted corrections to reduce legal exposure.

Designing NLRA-compliant confidentiality and privacy policies requires a careful drafting approach that protects legitimate employer interests while building in explicit carve-outs for employees' Section 7 rights. The most important principle is specificity: policies should identify exactly what information is considered confidential—trade secrets, customer data, financial projections, legal strategy—rather than using broad language that could be read to encompass employees' discussions of wages, working conditions, or employer conduct. Adding an explicit statement that the policy does not prohibit employees from discussing wages, hours, or other terms and conditions of employment with coworkers significantly reduces NLRB vulnerability. For investigation confidentiality, policies should frame confidentiality as situation-specific rather than blanket, with language that ties it to a particularized business justification and a defined time period. Social media policies should include positive statements about employees' rights to discuss workplace matters online while focusing restrictions on disclosure of genuinely confidential business information. Policies should be reviewed by employment counsel familiar with current NLRB precedent, particularly when standards shift with NLRB leadership changes under new administrations. All policies should be drafted in clear, plain language that employees can understand without legal interpretation. Regular handbook audits—at least annually and following major NLRB decisions—ensure ongoing compliance.
