Great headline, terrible article. It mostly talks about German words and almost nothing of German work ethics. The only interesting bit is around the end where it quickly skirts over the fact that you need to make employees realize they are unproductive before you can work on their behavior.
All the other stuff is just meh. I mean, the language analysis isn’t even very good, or in depth, with terrible half-assed English translations.
Basically, don’t waste you time reading this.
