Due to an unusually high number of sick days at the German Tesla factory, Managing Director André Thierig and Head of Human Resources Erik Demmler visited employees unannounced at home. They were not amused.
That shit is extremely rare over here in Germany, and it will not improve employee satisfaction or their commitment. And you are not bound to open the door anyways or to stay home when you are sick (you can get better at your partners place, no problem) so simply don't open the door when you are sick.
If they tried this in Australia Fairwork would go so far up their arses they'd never come back out. I'm presuming Germany has even more robust worker rights
