Germans are smart and efficient, even when they go on strike!

Intelligent Strike Paralyzes Frankfurt Airport.
F.G.Helmke
After a small group of workers on the airport apron resumed a strike over pay on Friday, almost 300 flights were cancelled at Frankfurt, Europe’s third largest airport. They said the action could continue next week.
German unions don't like using big numbers of workers to strike,  because of the high cost of such actions. Instead, few people in strategic positions are  being used to bring complex operations to a halt. The effect of the strike is the same, but  risks and investments remain much smaller
