Don’t think it is very different in Germany, Austria and Switzerland:

In a survey of more than 2,200 workers in the US, UK and Australia conducted online by Harris Poll last month, Clarizen found US workers waste as much as 30 percent of the work week (assuming a 40-hour week) preparing for and attending status meetings.
That’s 11.8 hours per week, or nearly a day and a half of meetings and meeting preparation.
What’s left: 3.5 days of actual work.
