Can remember my bosses in the 80s bringing in the New Hires and putting them on MY Shift, expecting ME to get them up to speed. I was having enough issues with guys that would drag ass thinking could slip Straight Time into a Chargeable hours job. One guy was taxed with wiring up side markers on a framed 32' dump trailer, supposed to be a electrical whiz but proved just a whiz. Got the wiring done so showed me lights worked, told him would not last where had to raise the bed for proof to him as he wired DROOPED UNDER THE RAILS that pulled away as soon as got it lifting. He looked at me and said 'The Frame does not raise too?' Another two hours of rerouting nothing worked so fired him, finished the job myself, took less than a half hour. Fired SEVERAL of this caliber of Uselessness, many could not even gain employ at the local dump. One guy was hired as a 'Detroit Tech', where had a low power complaint that had several filters changed by owner made no difference, first thing he asked for was filters, first thing I told him was check transfer pressure and lines for rubs, got deer in headlights double blink and he asked, How do you check pressure? He lasted another hour staring at the truck with a pressure gauge sitting on the frame rail. Could not find the transfer pump on a 6L71 in a CO4070A IH.
