Democratic senators urge Delta to remain neutral in union organizing effort

"Delta flight attendants have been exercising their right to organize for years, leading coordinated union campaigns since the 1990s," Warren and Markey wrote, citing reports that Delta has said joining a union would jeopardize its employees’ benefits and publishing an official Delta anti-union website.

The senators cited emails reportedly sent to staff by Delta last year telling flight attendants that signing union authorization cards would cause "inner turmoil" at the company and said under the law workers can organize without intimidation or interference.

Airline unions can file for a representation election with the National Mediation Board once a majority of workers have done so. Delta's pilots are already represented by the Air Line Pilots Association.

WASHINGTON, Sept. 9 (Reuters) - Two Democratic senators on Wednesday urged Delta Air Lines CEO Ed Bastian to remain neutral in ongoing efforts by some airline flight attendants to unionize.
