And this news from Atlanta: Delta Air Lines’s 20,000 flight attendants have filed enough authorization cards to call an election for union representation with the Association of Flight Attendants. The unionization effort is one of the largest US organizing drives in decades. The union says it’s the largest-ever union election in the airline industry. Last week, the union filed a complaint against Delta with the NMB, the National Mediation Board, accusing the airline of intimidating and harassing workers trying to organize the flight attendants.
