Had 2 cart pushers die; one was an old guy, he fell out on the lot. Other was a middle aged dude, alcoholic, kept coming in from the lot to cool off, management kept sending him back out. He came back in one last time and died of a heart attack right in the foyer.
Over the years since I've been gone I've lost 3 people I used to work with. Cancer and heart attacks. One guy almost died on the job, in produce, but one of the mgrs cpr'd him back. He went on early retirement after that.
You stick on any job long enough and you'll see people check out, sometimes while on the clock. It happens.
