You don’t need a vote for „Warnstreik” (warning strike), which frequently is enough to make a point, which makes the „real”/open-ended strikes much more rare than otherwise.
AFAICT all strikes I’ve ever seen happen here (the plethora of different train and airport unions) were technically warning strikes and not „real” ones; but they were enough to get the unions their wins.
