There are many labor relations consultancies in the United States and worldwide. They specialize in industries such as entertainment (radio, television and motion picture), hospitality (culinary and food service), communications, manufacturing, aerospace, utilities, and healthcare. Although many operate only in the United States, trade union organizing takes place multi-nationally. According to the AFL-CIO, "one of the largest U.S. firms, Labor Relations Institute (LRI), offers a “Guaranteed Winner Package”: if the corporation doesn't "win", it doesn't pay. In both the U.S. and Europe, organizing campaigns increasingly involve immigrant non-English speaking workers. Internationally, compliance with labor laws within developed countries can be vastly different from emerging countries. Both trade union organizers and management must know the law and avoid unfair labor practice (ULP) charges.
