🗞️ Undercover and Overlooked: NLRB Rules That Tech Escort Drivers Are Security Guards, Blocking Teamsters Bid

A federal labor board official has ruled that a group of security workers who drive engineers through San Diego in unmarked vans, deliberately dressed to blend in with the public, are nonetheless statutory "guards" under federal labor law. The decision, issued May 5, 2026, by the National Labor Relations Board's Region 21 office, dismissed a petition filed by Teamsters Local 542 to represent the workers, known as Escort Protection Agents, employed by Universal Protection Service, LP, doing business as Allied Universal Security Services.

The ruling turns on a provision of the National Labor Relations Act that has long set security guards apart from the broader labor force. Under Section 9(b)(3) of the NLRA, guards may only be represented by a union whose membership is limited exclusively to other guards. Because the Teamsters also represent non-guard workers, including truck drivers and warehouse employees, the union is legally barred from serving as the collective bargaining representative of a guard unit, regardless of whether a majority of the workers in question might want Teamsters representation.

The decision places Allied Universal's Escort Protection Agents squarely within the guard classification, despite the fact that they carry no weapons, wear no uniforms, and are specifically instructed to avoid any visible sign of a security function. That deliberate inconspicuousness, Acting Regional Director David Selder wrote, was not evidence against guard status but rather central to the job itself.

The client at the center of the case, a large technology company whose identity was shielded by a protective order throughout the proceeding, relies on the agents to escort engineers during confidential field tests of current products and prototypes. The agents drive specially outfitted cargo vans, keep watch over sensitive prototype equipment left inside when engineers step out of the vehicle, deflect public curiosity, and report security-related incidents up the chain of command. While on duty, each agent wears a client badge that grants access to the client's facility; a guard license is attached to the same badge reel, and the client badge itself is stored in a case that blocks the client's logo, ensuring nothing visible in the field can identify the technology company.

Allied Universal argued from the outset that these responsibilities, which include monitoring surroundings, engaging with members of the public who approach the van, preventing unauthorized persons from entering the vehicle, and escalating potential security breaches, are the functions of a guard, not a driver. The Teamsters countered that the workers function essentially as chauffeurs, and that incidental security duties should not transform them into guards under the statute.

Selder sided with the employer. Applying the multi-factor test established in The Boeing Company, 328 NLRB 128 (1999), which requires that guard responsibilities constitute more than a minor or incidental part of an employee's overall duties, the regional director found that the Escort Protection Agents spend a substantial portion of their working time on security functions. Those functions, he found, include active threat prevention and de-escalation, not merely locking a door or filing a report.

The Teamsters argued that the agents more closely resemble the couriers the Board found were not guards in Pony Express Courier Corp., 310 NLRB 102 (1993), and Purolator Courier Corp., 300 NLRB 812 (1990). In both those cases, the Board concluded that delivery drivers whose security obligations amounted to little more than commonsense practices did not qualify as statutory guards. Selder distinguished those precedents on several grounds: Allied Universal holds itself out as a security company, not a delivery service; the tech client's prototypes carry substantial value that depends on secrecy; and the agents receive training in conflict de-escalation, reading body language, and confidentiality that goes well beyond what was offered to the Pony Express or Purolator couriers, whose minimal training involved passively reading written materials and whose required security practices covered little more than locking doors.

The ruling also addressed the agents' lack of traditional guard attributes. They carry no weapons and receive no weapons or self-defense training. They are not uniformed. The decision acknowledged these omissions but cited Board precedent holding that guard status cannot be determined by a mechanical checklist. What matters is the specific nature of the duties, and here the agents are directly charged with ensuring the secrecy and security that is intrinsic to the value of the client's property and field operations.

The Teamsters and Allied Universal both presented witness testimony and documentary evidence at a hearing on January 28, 2026. Any party wishing to challenge the ruling may file a request for review with the NLRB's Executive Secretary in Washington by May 19, 2026.

Key Points

• The NLRB's Region 21 dismissed a Teamsters petition to represent Escort Protection Agents employed by Allied Universal at a San Diego technology company's field testing program.
• Under Section 9(b)(3) of the NLRA, guards can only be represented by a union that exclusively admits other guards; because the Teamsters also represent non-guard employees, certification was legally impermissible.
• The agents transport engineers during confidential field tests of current products and prototypes, monitor for security threats, engage with the public to deflect attention from the van and engineers, and remain with the vehicle to secure prototype equipment when engineers are away.
• Acting Regional Director David Selder found the agents' security duties were substantial and primary, not incidental, applying the Boeing (1999) multi-factor standard.
• The agents wear no uniforms and carry no weapons by design, a feature the ruling found consistent with, not contrary to, their security function.
• The ruling distinguished the agents from couriers in the Pony Express and Purolator cases, where security obligations were minimal and the employer's core business was delivery, not protection.
• Any party may request review from the NLRB Board in Washington by May 19, 2026.
