I guess most people here are going to say that he's pushing his workers too hard, and that they're losing faith. I think it's just much more difficult than people appreciate to build a successful car company, and some people will have their lives spent building it. I think that even if 1 in 100 employees flat out died because of Tesla, the company and Elon should carry on without slowing down anything. It's just too important that we transition out of a carbon economy.
Besides, I don't think conditions are really that bad. This is obviously a smear piece indicated by mentioning the Model X delays in TFA - What does that have to do with workplace injuries? Nothing, but they're trying to bring down Elon and his companies.
Workplace injuries are bad, but Elon is a poppy that's 100 times taller than the rest. I think they're trying to cut him down more than anything. May the old-school unions be perpetually denied any access to his factories.
