Highly odd for a company that's just starting production of its highest-volume product ever.
Is there something about Tesla beyond the hype we should know? If I were an investor, this news would have me quite concerned.
You would think they can't hire fast enough.
The plan as I understand it was to use the technology at this company to speed up production but it hasn't been going as planned, in large part due to misunderstanding of cultural differences i.e. No one is going to be happy here in Germany if you start changing the terms of contracts that were supposed to last for the next few years and people in general don't respect abusive bosses. Unemployment rate is 3%, no need to (and lower for highly skilled workers). And you can't just tell people to not take vacation because production is behind, you'll get laughed at.
And yes, this has happened a few times now - American corp buys some German corp and replaces managers with American ones (or American-styled ones) and a few years later no one in the industry wants to work for them any more.
It sounds a bit rough but sometimes you need to let people go, for a variety of reasons. Long term, I'd only be concerned that it gave them a poor reputation because they didn't adequately warn people and that may turn away good applicants. But, that seems unlikely, so I'm not terribly concerned.
My investment in Tesla is worth about 10x what I invested, last time I checked. I don't check often as it is a long-term investment. I feel comfortable keeping my trust in Musk.
