At one place, a guy who had left the company a few months prior died in a car crash. The guy had a wife and newborn baby. The CEO shared the news and the company made a contribution to a GoFundMe for the wife and baby. I think the company offered grief counseling.
At another, larger company, someone died shortly after I joined, so I never knew them. We were all notified, once again I think a grief counselor came, and the guy’s desk was left as a memorial until we moved offices a few months later.
