The Tribal Labor Sovereignty Act of 2025 seeks to clarify the application of the National Labor Relations Act (NLRA) to Indian Tribes and their enterprises. It proposes to amend Section 2 of the NLRA by explicitly excluding Indian Tribes and any enterprise or institution owned and operated by an Indian Tribe and located on its Indian lands from the definition of "employer." This exclusion would mean that the NLRA's provisions regarding labor relations, such as collective bargaining and unfair labor practices, would not apply to these tribal entities. The bill further provides specific definitions for key terms to ensure clarity in its application. It defines "Indian Tribe" as any federally recognized group, "Indian" as a member of such a tribe, and "Indian lands" to include reservations, trust lands, and certain lands in Oklahoma. These definitions are crucial for delineating the scope of the proposed exemption from federal labor law.
