A union representing pilots at Deutsche Lufthansa AG says it is calling a four-day strike for mid-April after failing to resolve a dispute over pay and job security.

The Cockpit union said on Monday the strike is set to run from April 13 through 16.

Cockpit said talks with Germany’s biggest airline have “remained without a result.”

It said it was delaying the start of the planned strike until mid-April to avoid disruption during the Easter vacation and give Lufthansa’s management “time to realign its course.”

The pilots already staged one strike last month. A planned four-day-walkout was cut short then with an agreement to resume negotiations.
