German union calls one-day strike at Lufthansa on Monday

The German services sector union Verdi on Friday called for a one-day walkout by all Lufthansa staff at German airports on Monday in an escalating pay dispute.

"Verdi has called on Lufthansa employees to stage full-day warning strikes at German airports on April 22 after management failed to come up with a negotiable pay offer in the third round of pay talks on April 17," the union said in a statement.
