Tribal Labor Sovereignty Act 2025: the NLRB jurisdiction question, explained

The Tribal Labor Sovereignty Act of 2025 — companion bills H.R. 1723 in the House and S. 1301 in the Senate — has quietly become one of the most consequential federal proposals before the 119th Congress for tribal gaming. The legislation would amend the National Labor Relations Act to exclude enterprises owned and operated by federally recognized tribes from the statute's coverage, reversing a line of administrative and judicial decisions that have asserted NLRB jurisdiction over tribal gaming operations since 2004.

For tribal operators, the bill is framed as a sovereignty issue. For organized labor, it is framed as a worker-protection issue. The dispute has been litigated in some form for more than two decades, and the current proposal represents the latest attempt to resolve it through statute rather than through case-by-case adjudication.

How NLRB jurisdiction over tribal gaming evolved

Until 2004, the NLRB applied the Fort Apache Timber Co. precedent, under which the National Labor Relations Act did not apply to tribal governmental enterprises. That changed in San Manuel Indian Bingo and Casino, in which the Board concluded that commercial enterprises owned by tribes — including casinos — could be subject to NLRA coverage even when located on tribal lands. The D.C. Circuit upheld the Board's decision in 2007, and the Sixth Circuit reached a similar conclusion in NLRB v. Little River Band of Ottawa Indians in 2015.

Since those decisions, the Board has generally exercised jurisdiction over tribal commercial enterprises while declining to assert jurisdiction over enterprises performing traditional governmental functions. That distinction has produced ongoing case-by-case litigation about which activities sit on which side of the line — a problem that affects not only casinos but also tribal hotels, retail, fuel and tobacco operations and ancillary businesses.

California has been a notable carve-out. A subset of California tribes — including the Agua Caliente Band of Cahuilla Indians, the Pechanga Band of Luiseño Indians and the San Manuel Band of Mission Indians — adopted Tribal Labor Relations Ordinances as part of their compact framework. Those ordinances provide for organizing rights, mediation and arbitration through tribal forums, and they were intended to substitute for NLRA coverage. Whether and how those ordinances interact with the NLRA in disputed cases remains contested.

What the 2025 bill does

H.R. 1723 and S. 1301 would amend Section 2(2) of the NLRA to explicitly exclude any enterprise or institution owned and operated by a federally recognized Indian tribe and located on tribal lands. The Congressional Budget Office has estimated the bills would reduce the number of employers subject to NLRB oversight, though the precise count depends on how the statute is read against the existing jurisdictional standards the Board applies.

Supporters — including the National Indian Gaming Association, the National Congress of American Indians and several large tribal operators — argue that the bills restore parity with the way the NLRA already treats state and federal government employers, both of which are excluded from coverage. The argument is that tribal governments, as a third sovereign in the U.S. constitutional system, should be treated consistently with the other two.

Opponents — including major service-sector unions — argue that tribal commercial enterprises operate in interstate commerce, compete directly with non-tribal commercial gaming, and should be subject to the same federal labor-law floor as their commercial competitors. They have also argued that some tribal labor ordinances do not provide protections equivalent to the NLRA.

"This is a sovereignty question first and a labor-policy question second," a tribal legal advocate testified before a House subcommittee earlier this year. "Tribes can and do regulate labor relations on their own lands. The federal question is whether Congress will recognize that authority or override it."

What's actually at stake for operators

For the largest tribal gaming operators, the practical stakes vary. Many have either negotiated labor agreements with relevant unions, adopted their own tribal labor ordinances or operated in workforce environments where union density is relatively low. For those operators, the bills would primarily settle a long-running jurisdictional uncertainty rather than transform day-to-day operations.

For mid-sized operators and for tribes whose gaming enterprises are deeply integrated with governmental services — health, social services, education funded by gaming revenue — the bills would have a more direct effect. They would foreclose unfair-labor-practice charges before the NLRB and require any organizing or grievance activity to proceed through tribal forums or through whatever forum a tribal labor ordinance provides.

The bills do not change anything about how IGRA's compact and revenue-sharing structure works. They also do not affect classification of gaming activity under Class II versus Class III rules, nor the National Indian Gaming Commission's regulatory role.

What to watch next

Both bills have moved through committee in their respective chambers, with markups during the spring. Floor timing in the current congressional calendar remains uncertain, and similar bills have stalled in past Congresses. Even so, the legislative posture in 2026 differs from past attempts in two ways. First, the bills have a broader coalition of tribal supporters and bipartisan co-sponsorship. Second, the Department of the Interior has been increasingly active in tribal-state compact review under Part 293, which has elevated tribal-government regulatory authority generally.

The outcome — whether by statute, by a future Supreme Court case or by continued case-by-case Board adjudication — will set the labor-relations operating environment for an industry whose gross revenues now exceed 43 billion dollars annually and whose workforce comprises hundreds of thousands of employees across more than 240 tribes.
