Take a look for yourself: https://www.qwant.com/?q=tesla%20workers&t=news
I looked, it's an exaggeration to say every week.
Also, the subtext of your comment - that this person OF COURSE would have contacted a news organization if their claim was legitimate is frankly very weird.
What I (not the original poster of the comment you are questioning) is that they were injured in the workplace at Tesla as en employee and unable to get anything from Tesla to deal with that, since workers compensation is a bright-line legal requirement for all employers and covers all employees.
Now, bureaucratic difficulties dealing with Tesla’s WC insurer resulting in annoying runarounds, poor doctors in inconvenient locations, and disappointing care quality would be credible. Crickets, though, stretches belief.
This comment says a lot more about you than it does about the OP and from now on I will consider everything you write on HN to a lie.
It's foolish to believe anything you read on the internet: it's a tissue of lies and propaganda. Something like 83.2% of everyone you talk to online is actually someone else.
Why, I myself am a marmoset, but would you ever know it if I hadn't told you?
Extended legal action may very well be why there aren't big stories about this.
Has your friend spoken to news agencies about this? Why not, if he/she hasn't? Surely any of the major news agencies would be watering at the mouth for a story like this.
