The state has relatively little say in the regulation of labor unions. This is because most of the protections given to labor organizations are contained in the National Labor Relations Act (NLRA), a federal law. This law is “preemptive;” that is, it overrides state law in the areas that it covers, which include almost all types of private employment. However, in the areas it does not cover, such as the rights of farmworkers and employees of businesses that do not engage in interstate commerce, states are free to make their own provisions. Mississippi has adopted no provisions that provide for the unionization of employees not covered by federal law.
