Transport staff across Germany are set to stage a major strike on Monday to push for wage hikes in the face of brisk inflation, as passengers brace for serious disruptions.

Workers at airports, ports, railways, buses and metro lines throughout much of Europe's top economy are expected to heed a call by the Verdi and EVG unions to the 24-hour walkout.

"A labour struggle that has no impact is toothless," Verdi chief Frank Werneke told public broadcaster Phoenix.

He acknowledged that it would inflict pain on many commuters and holidaymakers, "but better one day of strain with the prospect of reaching a wage agreement than weeks of industrial action".

To prevent supply gaps, Transport Minister Volker Wissing has ordered states to lift restrictions on truck deliveries Sunday, while asking airports to allow late-night takeoffs and landings "so stranded passengers can reach their destinations".

Verdi represents around 2.5 million public sector employees, while EVG represents 230,000 workers on the railways and at bus companies.

The rare joint call for a strike in Germany marks an escalation of an increasingly ill-tempered dispute over a pay packet to blunt the impact of surging inflation.

Employers, mostly the state and public sector companies, have so far refused the demands, instead offering a rise of five percent with two one-off payments of 1,000 ($1,100) and 1,500 euros, this year and next.

Verdi is demanding a rise of 10.5 percent in monthly salaries, while EVG is seeking a 12-percent rise for those it represents.

'Massive impact'

State-owned rail company Deutsche Bahn (DB) has completely suspended all long-distance trains for the day and many regional and local connections will be at a standstill.

DB's Martin Seiler, responsible for human resources on the company's management board, described the nationwide strike as "groundless and unnecessary" and urged the unions to return to the negotiating table "immediately".

The company expects the walkout to have a "massive impact" on its entire rail network and has pledged to inform its customers "as quickly and comprehensively as possible" about cancellations and delays.

The German airport association, which estimated about 380,000 air travellers would be affected, said the walkout "went beyond any imaginable and justifiable measure".

Employers have accused labour representatives of contributing to a wage-price spiral that will only feed inflation, while unions say their members have been asked to bear the burden of the soaring cost of living.

"Petrol and food prices have risen, I'm feeling it in my wallet," Timo Stau, 21, told AFP at a protest on Thursday in Berlin.
