Verdi calls for a warning strike at the Hamburg Hochbahn. Buses and subways should also come to a standstill in Hamburg.

Verdi demands shorter working hours without financial losses, longer rest periods between individual shifts, more vacation days or more vacation pay. The S-Bahn, which belongs to the Deutsche Bahn group, is not affected by the strike. The union's goals and demands differ depending on what type of collective agreement is being fought for.
