The National Labor Relations Board (NLRB) ruled against Wackenhut [part of Group 4 Securicor] in a case involving security workers who sought to organize a union at the headquarters of the International Monetary Fund (IMF) in Washington, DC... The NLRB upheld an administrative law judge's finding that Wackenhut illegally intimidated and interrogated security officers Anderson Carter and Terry Purnell, who were leading an effort to encourage their co-workers to become members of Service Employees International Union (SEIU).
