German pilots working for Ryanair have overwhelmingly voted to strike as they push for collective labor agreements at Europe's largest low-cost carrier, their union said on Monday, adding to Ryanair's recent strike woes.

Ryanair management had met with the Vereinigung Cockpit (VC) pilot union in Frankfurt last week. VC said the talks ended without the progress they had hoped for.

The union is giving Ryanair until Aug. 6 to make another offer, VC said in a statement, announcing it would hold a press conference on Aug. 8 to discuss its next steps.
