New NLRB Rule on Employee Email Use: Implications for Employers

NLRB Rule Change

On May 10, 2026, the National Labor Relations Board (NLRB) issued a significant rule change affecting employer email policies. The new rule allows employees to use their work email systems for union organizing and other protected concerted activities during non-working time. This decision reverses the 2019 ruling in Caesars Entertainment Corp., which had restricted such use.

Impact on Employers

This rule applies to employers who have chosen to give employees access to their email systems. It does not mandate that employers provide email access if they do not already do so. However, for those who do, the rule requires that employees be allowed to use email for union activities, provided it does not interfere with workplace operations or productivity.

The ruling emphasizes the importance of email as a critical tool for communication in modern workplaces, recognizing it as a virtual equivalent of the breakroom discussions protected under Section 7 of the National Labor Relations Act (NLRA).

Action Items for Employers

Employers should review their current email use policies to ensure compliance with the new NLRB rule. This includes:

• Policy Updates: Revise email and electronic communication policies to explicitly permit the use of email for Section 7 activities during non-working time.
• Training: Conduct training sessions for management and HR professionals to understand the implications of the rule and how to enforce it without infringing on employees' rights.
• Monitoring Practices: Review and adjust monitoring practices to ensure they do not unlawfully restrict protected activities or discriminate against union-related communications.

Legal Considerations

Employers must carefully balance their rights to maintain productivity and prevent misuse of email systems with employees' rights to engage in protected activities. Violations of this rule can lead to unfair labor practice charges. Legal counsel should be consulted to navigate these changes and potential disputes.

This rule underscores the NLRB's ongoing efforts to enhance protections for employees engaging in union and concerted activities. Employers should remain vigilant in updating policies to comply with evolving labor standards.
