Striking Berlin airport workers may cease giving notice of walkouts after Ryanair Holdings Plc began using its own ground staff to help maintain services from the German capital.
The tactic of bringing in foreign “strikebreakers” poses a security threat because the Ryanair employees are being granted so-called air-side access without sufficient checks, the Ver.di union said Tuesday.
The labor group, which represents about 2,000 striking staff at six ground-handling providers, may now deviate from its practice of announcing each walkout a day in advance to give people time to change their travel plans.
