How to Search NLRB Cases: Complete Lookup Guide (2026)

How to Search NLRB Cases by Employer Name

The National Labor Relations Board maintains a public database of every unfair labor practice charge, representation petition, and election result filed since the late 1970s. Over 500,000 filings are in the system, covering nearly five decades of labor relations activity.

But finding what you need depends on which tools you use. NLRB.gov’s own search covers NLRB data only. Cross-agency platforms link NLRB filings to the same employer’s OSHA inspections, DOL wage violations, and SEC filings—revealing patterns that single-agency searches miss.

Option 1: NLRB.gov Case Search

The NLRB provides a free case search tool at nlrb.gov/case.

• Go to nlrb.gov and click “Search Cases”
• Enter the employer name, case number, city, or state
• Filter by case type: CA (unfair labor practice against employer), CB (against union), RC (representation petition), RD (decertification)
• Results show case number, parties, status, date filed, and region
• Click any case number to see the full case history and documents

Understanding NLRB case type prefixes is essential for effective searching.

Limitations of NLRB.gov Search

The NLRB’s search tool works for individual case lookups but has significant limitations for professional research.

• NLRB only: no connection to DOL wage theft cases, OSHA safety violations, or SEC filings
• No entity resolution: “Walmart” won’t find “Wal-Mart Stores Inc.” or “Walmart Supercenter #764”
• No risk scoring or pattern analysis across cases
• No corporate hierarchy: can’t see if a subsidiary’s parent company has a pattern of ULP charges
• No cross-agency timeline: can’t see if NLRB charges followed OSHA citations (a common escalation pattern)

Option 2: Cross-Agency Employer Lookup

Cross-agency enforcement platforms search NLRB alongside DOL WHD, OSHA, SEC EDGAR, and state attorneys general simultaneously. Entity resolution links records across agencies even when employers use different names.

LaborAudit’s database includes over 500,000 NLRB filings linked to 108,000 employer entities. When you search for an employer, you see their complete enforcement profile: NLRB charges alongside OSHA citations, WHD wage cases, and SEC corporate relationships.
