Berlin Airport cancelled all its flights Wednesday after ground staff went on strike to press their demands for higher pay. The walk-out affected about 300 flights to and from the German capital.

Labor union Verdi said its members are seeking a raise of €500 ($731) per month.

German news agency dpa reported that employers have offered staff a one-off payment of €2,000.

Germany experienced its highest annual inflation in more than 70 years last year.

Sharp increases in the cost of food and energy saw full-year inflation reach 7.9% in 2022.
