US National Labor Relations Board case search — unfair labor practice charges and union representation/election petitions (~516,000 cases), read live from the NLRB’s public case search on nlrb.gov.

Tools

• nlrb_search(query, case_type?, status?, filed_since?, filed_before?, region?, sort?, limit?, page?) — finds cases by employer name, union name, or case number. Returns case number, case name, date filed, open/closed status, city and NLRB region, plus the total number of matching cases. Answers “is Starbucks facing an NLRB charge”, “union election petitions at Trader Joe’s”.
• nlrb_case(case_number) — the full docket for one case: allegations charged under the National Labor Relations Act, status, location, region, participants (charged party, charging party, employer, union, and their legal representatives), the docket activity log, and — for representation cases that reached a count — the election tally (eligible voters, ballots counted, votes for and against the union).
• nlrb_recent_filings(days?, case_type?, status?, region?, limit?) — newest filings nationally over a recent window, newest first, with the total filed in that window.

Data sources

• https://www.nlrb.gov/get-search-data/{term}/cases?sort=&rows=&page= — the case search. A Drupal AJAX endpoint: it returns a command array whose data fields carry the rendered result HTML and whose trailing invoke command carries the total match count in args[4].
• https://www.nlrb.gov/case/{case-number} — the server-rendered case docket.

Things worth knowing before you touch this pack

• The tab segment must be cases, plural. /get-search-data/{term}/case is refused by the site’s WAF with an HTTP 200 carrying a “Request Rejected” HTML page — a rejection that reads as a success unless you inspect the body. The pack checks for that page and returns { found: false, reason: 'blocked' }.
• The search term is a path segment, so a / in it silently changes which endpoint you hit. Slashes are stripped and the term is URL-encoded.
• Query parameters on /search/case are ignored. The visible search form POSTs; ?search_term=Starbucks returns the unfiltered 516k listing with the header still reading “for all”. Only /get-search-data/... honours a term.
• Filters ride as bracketed params: f[0]=case_type:C (or case_type:R, or (case_type:C OR case_type:R)), s[n]=Open|Closed|Open - Blocked, r[n]=<region>, state[n]=<XX>, and date_start/date_end in MM/DD/YYYY — ISO dates are ignored rather than rejected, so the pack converts.
• Sort accepts desc (newest), asc (oldest) and relevance; rows and a zero-based page both work, confirmed to rows=50.
• Case numbers are region-type-serial (10-CB-393760): 2-digit region, case type (CA/CB against an employer/union, RC/RD/RM for representation), serial. The pack uppercases and zero-pads a single-digit region.
• Election tallies exist only on R cases that reached a count, and render as a second label/value block on the case page, so a generic label scrape mixes them into the case header unless they are separated by label name.
• The docket activity table on a case page shows only the most recent entries and, per NLRB’s own footnote, does not reflect all actions in the case.
