"CNC machinists operate computer numerical control machines. For the uninitiated, this is a machine that operates a lathe or a mill. On the upside, it renders obsolete processes that used to be performed by hand, at a slow pace and with high risk to the operator’s life and limb.
Now that the CNC operator has had most of the physical hazards of manufacturing replaced by a machine, there’s not a lot to do but push buttons and perform equipment inspections to make sure the coolant is at a safe level. Since it’s a specialized skill, the job offers no room for advancement, which caused respondents to report a high degree of dissatisfaction."
