I haven't stopped thinking about it. If I die while I'm still working for my shitty company, I would never want to see my death so casually dismissed like this. What the fuck. This was a person. They don't deserve to have their death announced to some random employee in a different company along with their new hiree.
This was extremely upsetting to me and I don't know what to do about it. They could have just said they had hired someone else and I wouldn't have been haunted by their display of sheer corporate dehumanization.
