Ver.di is calling for warning strikes in public transport in almost all federal states. According to the union, over 130 municipal companies and a total of around 90,000 employees in cities and districts are affected.

Ver.di wants to put pressure on collective bargaining in local public transport; the union is primarily demanding better working conditions. More on SPIEGEL.de soon. The strikes are scheduled for Friday in all states except Bavaria. The action is expected to last for an hour and a half.
