Essential employees

People are expressing surprise at who are the essential workers like truck drivers, nurses, and food stockers. Early in my career, I worked in a food processing plant and there was a central dust collector system. This picked up dust from throughout the plant and packed in 50 pound bags and sold for hog feed. One morning there was an emergency and the supervisor failed to notice that the man who collected the dust did not show up. About four hours into the shift the entire plant shut down. The plant manager could go on two weeks vacation and no one would notice he was gone. I learned early on that the most important employees were not the ones you would suspect.
