Thousands of passengers at four German airports, including the biggest hub Frankfurt, were stranded on April 10th as ground staff and other public sector workers staged walkouts across the country to increase the pressure in a pay dispute.
Lufthansa said on Monday it was cancelling more than 800 of its planned 1,600 flights on Tuesday and Frankfurt airport operator Fraport has warned of disruption. As well as Frankfurt, airports in Munich, Cologne and Bremen were hit.
The industrial action also affected nurseries, rubbish collection services and swimming pools in several German states. Workers who stand to gain include airport ground crews, bus drivers, hospital staff, daycare employees and other municipal employees. Further strikes are planned in the coming days.
