A union that represents 50 service workers at the Federal Law Enforcement Training Center in Artesia could be under investigation from federal authorities, the latest in a dispute between a contractor and the union. The Carlsbad Current-Argus reported that the contractor said in a press release that a National Labor Relations Board investigator has been at the facility. “The Union’s attempts to coerce the government into termination of Omni’s contract at FLETC is unlawful,” the release said. It also alleges that the striking employees have performed unlawful actions, such as interfering with FLETC traffic by jumping in front of vehicles. The weeks-long dispute has caught the eye of U.S. Senators Tom Udall and Martin Heinrich, who sent a letter to Department of Homeland Security head Jeh Johnson.
