European travelers have contended for weeks with the possibility that Greece’s dwindling finances might lead to empty ATMs. They should have concerned themselves instead with Germany.

While cash machines in Athens are still operating without any trouble, striking couriers in Berlin this week stopped filling ATMs, leading to a crunch for those trying to make withdrawals. And the open-ended labor dispute with a local security company means there’s no end in sight.

Berlin’s strike is the latest in a series of walkouts that have riled a nation more accustomed to mocking the labor strife which has so often beset neighboring France. A strike by train drivers that began Tuesday is paralyzing travel and clogging highways throughout Germany. That action follows a March walkout by pilots at Deutsche Lufthansa AG that led to flight cancellations for 220,000 people.
