Verdi union calls for strike

German union Verdi has called on security staff at Frankfurt airport to go on strike on Tuesday to put pressure on firms in charge of screening passengers and luggage in wage talks. Verdi said on Friday that it was negotiating on behalf of 23,000 security workers in Germany. Wage talks are to resume on Jan 23, it said. Fraport, the operator of Germany’s busiest hub, said it expected severe disruption and asked passengers who were planning to start their journey in Frankfurt not to come to the airport during the strike, which is scheduled to last from 0100 to 1900 GMT.
