Tesla has about 100,000 employees yet people seem to operate under the absurd assumption that Elon is in every meeting, in every scrum, and sits in a cubicle managing the HR department. This is most definitely the decision of legal and HR and there’s an excellent chance Elon Musk knows nothing about it.
I can be fired at my 10k employee company after 20 years of service and the CEO will never know of my existence.
