'''Blue-collar workers''' are [[labor]]ers who work in [[factory|factories]] or other [[union]]-type jobs.  Blue-collar workers often use their hands, get their [[clothing|clothes]] dirty during the job, and do not sit behind a desk.  They are called "blue-collar" workers because of the sterotypical image of them wearing blue colored [[overalls]] or other work [[shirt]]s, rather than a white shirt and [[tie]].
