What Is a Tribal Labor Relations Ordinance (TLRO)? California Explainer

A tribal labor relations ordinance, usually abbreviated TLRO, is a tribal law that governs union organizing and collective bargaining at a tribal casino. In California, such ordinances have been a feature of tribal-state gaming compacts since the original 1999 agreements, and they remain one of the most distinctive labor provisions in Indian gaming. This explainer describes what a TLRO is, how it differs from federal labor law, and why it sits at the intersection of tribal sovereignty and workers' rights.

Why labor rules appear in a gaming compact

Under the Indian Gaming Regulatory Act, a compact may address subjects directly related to the operation of gaming activities, and states and tribes negotiate which provisions to include. Our overview of the scope of a tribal-state compact explains that negotiating framework. In California, the compacts negotiated in 1999 required each tribe to adopt a labor relations ordinance, or to adopt a model ordinance attached to the compact, covering certain casino employees. The compact therefore turned a labor-policy commitment into a contractual obligation between the tribe and the state.

The reason a tribe would adopt its own ordinance rather than rely on federal law traces to a long-running legal question about whether the National Labor Relations Act applies to tribal enterprises. Tribes are sovereign governments, and the federal courts have not always treated the statute the same way across circuits. The D.C. Circuit has held that the NLRA applies to a tribal casino on reservation land in the San Manuel case, and the Sixth Circuit reached a similar conclusion regarding a Michigan tribe's casino. Other disputes over tribal labor authority have continued in Congress and the courts. We discuss the legislative side in our analysis of the Tribal Labor Sovereignty Act.

What a TLRO typically provides

The specific terms vary by compact and by ordinance, and a reader needs the tribe's own text for authoritative detail. In general terms, a TLRO establishes a framework for how employees may seek union representation and how the tribe and the union interact. Typical elements include the following, described here at a general level.

Coverage rules define which employees are eligible. These ordinances commonly exclude certain categories, such as supervisors and managers, and employees in security or other sensitive regulatory roles, though the exact lists differ. Procedural rules govern how a union may access employees and request recognition, and how an election is conducted. Many models provide for an election overseen by a neutral tribal body rather than a federal agency. Unfair-practice provisions prohibit specified conduct by employers and unions, and dispute-resolution provisions set out how disagreements are heard, often by an independent arbitrator or tribal panel. Many ordinances also address the rights of a union to communicate with employees, subject to the casino's security and operational requirements.

Because each ordinance is a creature of tribal law, enforcement occurs through tribal processes. A tribe's sovereign immunity generally shields it from suit in state or federal court unless it has waived immunity, which is why the ordinances typically supply their own forums. Readers interested in how immunity and consent to suit work in compacts can consult our pieces on compact dispute resolution and sovereign immunity in patron disputes.

Who is covered and who is not

A frequent source of confusion is the scope of workforce coverage. A casino employs a wide range of people, including dealers, food service workers, housekeeping staff, maintenance workers, security officers, and administrative and management personnel. A TLRO applies only to those categories the ordinance defines as eligible, and some ordinances apply only above a minimum employment threshold at a facility. Employees of a tribe's separate governmental programs, such as a tribal health clinic or tribal administration, are generally outside a casino TLRO.

Federal and state wage-and-hour or anti-discrimination laws raise a related but distinct question. Which federal statutes apply to tribal enterprises depends on the statute and on how courts have read it, as laid out in our explainer on federal laws that apply to tribal casinos. A labor relations ordinance addresses organizing and bargaining; it does not by itself determine the application of other workplace laws.

The policy debate

Supporters of compact-based labor provisions argue that they give casino workers a defined process for union representation while respecting tribal self-government, since the tribe, not a federal agency, administers its own ordinance. Union representatives have, at times, contended that the processes under particular ordinances are harder to use than the federal process; tribal governments, for their part, have maintained that their ordinances provide meaningful rights and that tribal sovereignty includes the authority to regulate employment on tribal lands. Outcomes differ by tribe, and generalizations are risky. Anyone evaluating a specific casino should read that tribe's ordinance and any related compact language.

The debate is likely to remain active as compacts are renegotiated, because labor terms are a recurring topic in negotiations. Newer California compacts have continued to address labor provisions alongside device counts and revenue terms, as is described in our reporting on the 2026 compact package. State legislators, tribal governments and unions each bring different priorities to those talks.

How to find the rules for a specific casino

Compacts approved by the Interior Department are published on federal and state sites, and a tribe's labor ordinance is typically attached to or referenced in its compact. Starting with the state's compact repository and the California state hub can help identify which tribe operates a given property. For the wider legal setting, including how compacts are negotiated and approved, see the Legal Guide. Because ordinances can be amended and compacts can change, readers who need to rely on specific provisions should confirm the current text with the tribe or the state.
