Governments have relied on arbitration to resolve particularly large labor disputes, such as the Coal Strike of 1902. This type of arbitration, wherein a neutral arbitrator decides the terms of the collective bargaining agreement, is commonly known as interest arbitration. The United Steelworkers of America adopted an elaborate form of interest arbitration, known as the Experimental Negotiating Agreement, in the 1970s as a means of avoiding the long and costly strikes that had made the industry vulnerable to foreign competition. Major League Baseball uses a variant of interest arbitration, in which an arbitrator chooses between the two sides' final offers, to set the terms for contracts for players who are not eligible for free agency. Interest arbitration is now most frequently used by public employees who have no right to strike (for example, law enforcement and firefighters).
