Coalition of 40-Plus Groups Challenges Cal/OSHA Walkaround Rule That Could Put Third Parties on Your Jobsite
According to Safety+Health Magazine, a coalition of more than 40 organizations is pushing California to halt rulemaking on a proposed rule that would govern worker walkaround representation during Cal/OSHA inspections, escalating a fight that began at the federal level in 2024.
What’s Being Proposed and Who’s Pushing Back
The Cal/OSHA proposal follows a federal OSHA rule that took effect May 31, 2024, allowing workers to designate a non-employee representative, including a labor union member, to accompany inspectors during the walkaround portion of a worksite inspection. California is now pursuing its own version of that rule.
In an April 1, 2026 letter to Cal/OSHA’s staff counsel, the coalition, which includes Associated Builders and Contractors, laid out several objections. The group argues the rule exceeds Cal/OSHA’s statutory authority as a State Plan program under federal OSHA, conflicts with the National Labor Relations Act of 1935, violates employer property rights, and raises constitutional concerns. The coalition also contends the rule could endanger trade secrets, increase employer liability, and slow down inspections by discouraging cooperation.
A key argument centers on enforcement discretion. Under the proposed rule, the inspector alone would determine whether a third-party representative has legitimate credentials and authority. The coalition’s letter, as reported by Safety+Health Magazine, states: “Inspectors are not trained on the complexities of labor-management relations. That is why federal OSHA explicitly instructs inspectors to avoid involvement in labor-management disputes.”
What It Means for Subcontractors
- If this rule passes, a third-party representative, potentially a union organizer with no prior relationship to your company, could be present during a Cal/OSHA inspection of your jobsite without your invitation or approval.
- The coalition argues the rule’s “good cause” and “reasonably necessary” standards offer no real protection because the inspector holds sole discretion, meaning you’d have limited ability to challenge a third party’s presence on the spot.
- Subcontractors with proprietary methods, equipment configurations, or sensitive project details should take note of the trade secret concern raised in the letter.
- If you operate in California, now is the time to engage your trade association or legal counsel to monitor this rulemaking and submit comments if a public comment period opens.
- Federal precedent already allows third-party walkaround reps under OSHA 1903.8, so even if Cal/OSHA’s rule stalls, the federal version remains in effect for federal OSHA jurisdictions.
