BERLIN, Jan 23 (Reuters) - Germany's Ver.di union has called on Berlin airport staff in ground services, aviation security and at the airport company to strike on Wednesday in a wage dispute.
"The reason for the strike are parallel pay negotiations for which no solution has yet been found in all three areas," the union said on Monday.
The union said it expects many workers to participate and all air traffic to and from Berlin to be affected by the all day strike.
Berlin airport did not immediately reply to a request for comment. (Reporting by Kirsti Knolle; editing by Matthias Williams)
