The Machinists union wants to represent about 3,200 airport workers and reservations agents at Orlando-based AirTran, which has its largest hub in Atlanta. The union’s last bid for a representation election among those workers failed a year ago because the union did not submit enough signed cards from interested workers to warrant a vote.
There is a one-year waiting period before a union can file again for an election. The union must submit cards requesting an election from at least 35 percent of eligible employees. The National Mediation Board determines whether an election will be held.
