Union Pacific Corporation and the International Brotherhood of Boilermakers $(IBB)$ have reached an agreement to guarantee job security for union employees in connection with Union Pacific's planned merger with Norfolk Southern. This deal ensures that employees of both railroads who are union members at the time of the merger will have job security for life, subject to standard employment requirements. The IBB is the fourth national union to secure such an agreement with Union Pacific, following similar deals with SMART-TD, NCFO, and the Brotherhood of Railway Carmen. The agreements aim to protect union jobs as the companies move forward with creating the first coast-to-coast railroad in the United States.
