NLRB Cases

Every NLRB case back decades — 512,000+ unfair-labor-practice charges (C-cases) and union representation petitions (R-cases): employer name, city/state, region, filing date, status, closure reason, eligible voters, unit sought, and certified representative. The union-organizing and labor-dispute signal for any employer — same-day fresh for new filings.

What it returns

One record per case number (e.g. 03-CA-390171 — region 03, CA = ULP charge against an employer). case_type splits ULP vs representation; statuses refresh on a trailing 180-day window. On CB charges (against unions) the name field is the union. See the live example below for the full field set.

Filters

case_number	Direct lookup by NLRB case number (e.g., '03-CA-390171'). Fastest path.
employer_name	Case-insensitive substring against the named party (e.g., 'starbucks', 'amazon'). Usually the employer; on CB-type charges the union
state	Two-letter state/territory code of the case site (e.g., 'NY', 'CA', 'PR').
case_type	Case family: 'ULP' = unfair-labor-practice charges (C-cases), 'representation' = election/unit petitions (R-cases).
case_subtype	Exact case-number code (e.g., 'CA' charge against employer, 'CB' against union, 'RC' certification petition, 'RD' decertification). Client-side filter.
status	Case status. Client-side filter.
region	Two-digit NLRB region number from the case-number prefix (e.g., '03' Buffalo, '13' Chicago). Client-side filter.
since	date_filed lower bound (YYYY-MM-DD inclusive).
until	date_filed upper bound (YYYY-MM-DD inclusive).
sort_by	Sort key. Only date_filed is supported (the default).
sort_order	Default: desc (most recently filed first).
limit	Maximum cases to return. Default 50, max 500.
