The difference between a Craft union member and a truck driver are not even in close. A craft member like an Electrician, plumber, or carpenter knew there trade. Were as truck driver doesn't, well at least now a days. I have ran into drivers some new and some senior that didn't know what a Johnson bar is, brake can, slack adjuster, the difference between a check engine light and an emission light, what are the max axle weights, if the truck has disk brakes or not ( yes the new one do), if the trailer/truck has a current annual inspection, and so many other general knowledge every truck driver should know.
So this is why we are not considered a craft so many are dumb or just play dumb so we get paid like we are all dumb
