I heard that expression used most often in industrial jobs and it was used around “working people” (those who were Blue Collar folks) and “non-working people” (those being the White Collar crowd…)… Where the Blue Collar folks work for a living and get their hands dirty doing it… And the White Collars who actually do not do much more than shuffle papers and sip coffee… I served in the Air Force for over 30-years as an enlisted member and when newly appointed lieutenants would start to flash their rank around the young enlisted, I would tell them that there is a difference in the officer training school and the enlisted military basic training. Specifically, the officers are taught more gentlemanly things like: “to wash their hands after they use the restroom; while in basic training, the enlisted are taught not to ■■■ on their hands…” ---

I’m old now (69) and I use working gloves in the garage. However, sometimes you’re working on something tiny or in a hard to get to place and the gloves come off!
