The workingman often faces tough conditions on the job site.
Workingman → It is formed from "working" (from the Old English "weorc", meaning labor or effort) and "man" (from Old English "mann", meaning human being or person). The term "workingman" refers to a person who engages in labor or work, typically in a manual or industrial capacity.
Think of someone who is engaged in 'labor' ('weorc') and is a 'person' ('mann') — that's why a workingman is someone who works.
