The Centers for Disease Control and Prevention Business Responds to AIDS and Labor Responds to AIDS Programs (BRTA/LRTA) help large and small businesses and labor unions meet the challenges of HIV/AIDS in the workplace and the community. The site includes information on the program, including the Business and Labor Resource Service, which is a centralized information and referral service that links callers from business and labor with resources designed to help them prepare to manage issues related to HIV/AIDS in the workplace.
