German labor union ver.di says its members will stage a strike Tuesday at Frankfurt airport, Germany's biggest.
The strike is part of a broader dispute over pay in German public-sector jobs that also includes utility companies, kindergartens and municipal administrations.
Ver.di said Monday that strikes are also planned at Munich airport.
The union is demanding a 6 percent, or at least 200 euros ($245), pay rise for some 2.3 million public sector employees.
