FRANKFURT: Public transport workers across Germany will stage a 48-hour strike from Friday as talks over pay and conditions stall, a union said, potentially sparking travel chaos for millions. The Verdi union, negotiating on behalf of about 100,000 workers, said Tuesday it had decided to ramp up pressure on local authorities after making little progress in annual negotiations. The industrial action is likely to impact local buses, trams and trains in towns and cities across most of Germany on Friday, with the strike extending into Saturday in many places. But nationwide railway, road or air services are expected to run as usual. It is the second such strike in a matter of weeks, after a walkout at the start of February paralysed public transport. “Our colleagues urgently need relief – and employers need a clear signal that we are determined to fight for our demands,” said Verdi deputy chair Christine Behle.

The union is demanding higher bonuses for night and weekend work, a reduction in weekly working hours and longer rest periods. In some states, the union is also calling for salary increases of around 10%. In January there were walkouts in other parts of the public sector, including universities and schools, in protest at issues ranging from staff shortages to stagnating wages.
