A federal labor board is upholding an election at Delta Air Lines Inc. where baggage handlers voted against joining a union.
The National Mediation Board had been looking into claims by the International Association of Machinists and Aerospace Workers that Delta interfered in the election last year. About 54 percent of those workers voted against joining the union.
The National Mediation Board says the incidents that the union complained about were minor and did not show that Delta was trying to interfere in the vote.
Last month the same board found that Delta also did not interfere when flight attendants narrowly rejected a union. The votes have left pilots as the only large unionized group at the Atlanta carrier.
