How to Escalate a Complaint

1. Contact your specific branch directly. Robert Half operates with branch-level accountability — use the branch locator at roberthalf.com/us/en/locations to find the direct number for the branch handling your placement or account, and escalate to the branch manager or district manager by name.
2. Call 1-855-432-0924 and ask for a regional manager. Corporate escalation from the general line connects to Regional Operations for unresolved branch-level disputes — provide the specific branch office location and all prior contact details.
3. Send a certified letter to corporate HQ at Robert Half Inc., Attn: Client/Candidate Relations, 2884 Sand Hill Road, Suite 200, Menlo Park, CA 94025 — include branch office address, all prior case numbers, contact dates, and the specific resolution requested.
4. File with the BBB under the San Francisco Bay Area / Menlo Park chapter — Robert Half’s corporate BBB listing covers the Menlo Park and San Ramon addresses. BBB filings produce a formal corporate response.
5. File with your state’s Department of Labor or Labor Commissioner for wage disputes, misclassification issues, and staffing agency violations. In California, the Division of Labor Standards Enforcement (DLSE) has direct enforcement authority over staffing agency wage-and-hour violations.
6. File with the EEOC for discrimination, harassment, or hostile work environment complaints arising from a Robert Half placement — file at eeoc.gov or call 1-800-669-4000 within 180 days (300 days in states with their own anti-discrimination laws).
7. File with the FTC at reportfraud.ftc.gov for deceptive recruiting practices, misleading job postings, and unauthorized use of personal data.
