BERLIN — A union representing cabin crew for Lufthansa says its members will go on strike for one week in a contract dispute with the airline, Germany’s largest.

German news agency dpa quoted the head of the cabin crew union Ufo, Nicoley Baublies, saying Monday that the strike would run from this Friday to Nov. 13. He says an announcement about which flights would be affected will be made closer to the date.

Among other things, the union wants to secure transition payments for its 19,000 members if they retire early and says Lufthansa’s most recent offer was “completely unacceptable.”

Lufthansa says it’s prepared to continue negotiating.
