The article makes it quite clear that this is not about people dying like you mentioned, but about delayed medical attention in large Amazon facilities that result in potentially preventable fatalities.
In a massive warehouse, I can completely imagine there are lots of places you could collapse and nobody find you for a while. Right now, in my home office, if I were to collapse, it would probably be a few hours till my wife or children found me.
Presumably, the times when medical attention was given immediately aren't reported.
So basically it's about people dying like the guy described above, except that the Amazon employees didn't even technically die on the job because they were found relatively promptly and received medical care?
