Hoffman Plastic Compounds, Inc. v. National Labor Relations Board
The Supreme Court ruled that the National Labor Relations Board cannot award back pay to an undocumented worker who was illegally fired for supporting a union, because doing so would conflict with federal immigration law.
The 5-4 decision means undocumented workers who are illegally fired can still get other remedies, like a cease-and-desist order, but not the lost wages that are usually the labor board's most powerful tool for punishing employers.
How it got here: The labor board ordered back pay; the D.C. Circuit, sitting en banc, upheld that order; Hoffman asked the Supreme Court to review it.
The Case in Depth
What happened
Hoffman Plastic Compounds hired Jose Castro using documents that falsely appeared to authorize him to work in the U.S. When Castro helped organize a union, Hoffman fired him along with other organizers. The labor board found this an illegal retaliatory firing and ordered back pay, but later learned Castro had never been legally authorized to work in the country and had used a friend's birth certificate to get hired.
The question before the Court
Can a federal labor board award back pay to a worker who was illegally fired for union organizing, when that worker was never legally authorized to work in the United States?
The Court's answer
No — the Court ruled that the labor board could not award back pay to Jose Castro because he was never legally authorized to work in the United States. Awarding him wages for work he could never have lawfully performed, in a job he obtained by using fraudulent documents, would conflict with the strict system Congress built in IRCA to keep undocumented immigrants out of the workforce.
The Court held that although the board's remedial powers are usually broad, they aren't unlimited, and must give way when they clash with a separate federal law the board has no authority to enforce. Here, IRCA's criminal bans on document fraud and unauthorized employment outweighed the board's usual back pay remedy, even though Hoffman had illegally fired Castro for organizing a union.

Why it matters
Employers who fire undocumented workers for union activity now face a weaker financial penalty, since back pay is off the table for those workers. Immigrant workers organizing for better conditions have less legal leverage, while businesses lose less by retaliating against undocumented employees who unionize.
What changes now
The back pay award to Castro is eliminated, though Hoffman must still comply with the board's other orders, including posting notices about employees' union rights and refraining from further violations, enforceable through contempt proceedings. The ruling is final on the merits and directly governs how the labor board can remedy unlawful firings of undocumented workers going forward, absent new legislation from Congress.
What this does not decide
The Court did not decide whether back pay is barred for undocumented workers when the employer knowingly hired them, since that situation wasn't before it. It also left open whether such back pay awards might be an impermissible punitive remedy, since it resolved the case on other grounds.
Concurrences and dissents
Dissent — Justice Breyer
“Hence the backpay remedy is necessary; it helps make labor law enforcement credible; it makes clear that violating the labor laws will not pay.”Breyer's core objection that denying back pay undermines labor law enforcement.
Justice Breyer argued the back pay award did not conflict with immigration policy and that federal agencies, including the Justice Department, agreed it would not interfere with immigration enforcement. He contended back pay is essential to deterring labor law violations and that denying it actually rewards employers who exploit undocumented workers, undermining rather than protecting immigration goals. He would have deferred to the board's reasonable, carefully considered judgment.
How the Court got there
The legal reasoning, step by step
- The Court reviewed a line of its own cases holding that the labor board's remedial discretion, though broad, must yield when its chosen remedy conflicts with a federal statute or policy outside the board's expertise to administer, as in prior cases involving strikebreakers and mutineers.
- The Court found that the Immigration Reform and Control Act of 1986 (IRCA) created a comprehensive system making it illegal both for employers to knowingly hire unauthorized workers and for workers to use fraudulent documents to get hired, backed by civil and criminal penalties.
- Applying that framework, the Court reasoned that awarding back pay to Castro would require crediting him for wages from work he could never have lawfully performed, obtained in the first place through document fraud that IRCA criminalizes.
- The Court concluded that Congress's clear immigration enforcement scheme left no room for the labor board to treat back pay for undocumented workers as compatible with, rather than undermining, that scheme.
- The Court held that this back pay award fell outside the board's remedial authority, though it left in place the board's separate cease-and-desist and notice-posting orders against the employer.

Cases affected by this decision
Reaffirms Sure-Tan, Inc. v. NLRB (467 U.S. 883)
The Court relied on Sure-Tan's rule limiting back pay for workers not lawfully entitled to work in the U.S.
Distinguishes ABF Freight System, Inc. v. NLRB (510 U.S. 317)
The Court said this case differs because it involves misconduct that makes the underlying employment itself illegal.
