Behind the scenes, Lufthansa and the flight attendants' union UFO have been negotiating higher salaries for cabin crew. The employee representatives are demanding at least a 15 percent pay increase and have declared the talks a failure. A possible strike is now no longer being ruled out. Just a few days ago, both the pilots and the flight attendants at the Kranich subsidiary Discover Airlines went on a one-day strike. Now the UFO union could also call for a work stoppage at the parent company and at some operating subsidiaries that are also subject to the group's collective agreement. The consequences would be fatal, because a few years ago, in a similar industrial dispute, the UFO unionists managed to paralyze Lufthansa's flight operations for several days. The employee representatives made it clear just a few days ago in a press release that affected Lufthansa Cityline that the fronts have hardened. Management was accused of breaking its word, because the promised growth was not happening at Cityline, but rather this had been shifted to the new sister company City Airlines, which does not yet have a collective agreement. The demands are for significantly higher wages for the Cityline employees. Lufthansa calls for a return to the negotiating table So far, there have been a total of 14 rounds of negotiations between UFO and the Lufthansa management. Now the union representatives have unilaterally left the negotiating table - for the time being. A circular to members shows that the latest offer was considered "inadequate". According to the union, it represents around 18.000 cabin crew members of the Lufthansa Group. For these employees, the union is demanding a 15 percent increase in salary each month and a one-off payment of 3.000 euros. The union representatives cannot prevent any strike action.
