Total US COVID deaths: 28000/328000000 = 0.00008536585. So seemingly there's nothing particularly risky about being a grocery store worker. In fact, you're about half as likely to die!
Keep in mind the 328mm number includes children, non-working adults, etc and of course total deaths are skewed towards older non-working adults. Still it's extremely frustrating, but not surprising, that the media refuses to do any sort of cursory analysis like this.
