Associated Press, May 8, 2008 A close vote by nurses at three Southern Nevada hospitals has union officials disputing the outcome of a labor representation ballot. Administrators with the current bargaining unit, the Service Employees International Union, called the results of the Tuesday and Wednesday voting inconclusive. Officials with the upstart California Nurses Association say more nurses voted against the SEIU than for it. Neither side won the 50 percent plus one vote needed to claim representation of some 1,100 nurses at three Saint Rose Dominican Hospital campuses in Henderson and Las Vegas. The tally was 400 votes for the CNA, 377 for the SEIU and 26 votes for no union. Officials say the National Labor Relations Board will be asked to review six challenged ballots and probably set a date for a runoff election. Copyright 2008 by The Associated Press.
