Which agency oversees the longshore and harbor workers’ compensation program?

The correct choice is the U.S. Department of Labor, as it is responsible for overseeing various worker safety and compensation programs, including the Longshore and Harbor Workers’ Compensation Act (LHWCA). This program provides benefits to maritime workers who are injured or become ill due to their work related to loading and unloading ships, as well as those working on the docks.

The Department of Labor is tasked with ensuring that the provisions of the LHWCA are implemented properly. This includes maintaining regulations and guidelines that govern the compensation process, ensuring that workers receive the benefits they are entitled to, and promoting safe working conditions in the maritime industry.

Other agencies mentioned, like the U.S. Department of Justice, the Occupational Safety and Health Administration (OSHA), and the National Labor Relations Board (NLRB), have distinct roles. The Department of Justice primarily deals with legal enforcement and federal prosecutions, OSHA focuses on workplace safety regulations across various industries, and the NLRB centers on labor relations and workers' rights concerning union activities and collective bargaining. Thus, they do not have direct oversight of the longshore and harbor workers’ compensation program.
