Delta wins union dispute

The National Mediation Board has sided with Atlanta-based Delta Air Lines in a legal dispute. A national flight attendants union claimed the carrier interfered with a failed effort by some of its flight attendants to unionize. Delta says the NMB found that the union's claims either are "unsubstantiated," "do not rise to the level of interference." Delta's flight attendants failed to get the necessary votes to form a union. Not enough of the eligible flight attendants voted, and therefore the results did not meet the certification requirements of the NMB.
