Thirty five years ago was second shift Working foreman, had two mechanics and most days overwhelmed with jobs. Shop had but six drive thru bays so was difficult with long duration work taking holes to get daily stuff thru without working outside. Boss/owner decided I needed MORE help to clear the building for the next day shifts load and hired a guy was recommended by a 'Friend'. First day shows up all his tools fit in a tote box, not a road box, not a work box but a tote box, asks where the company tools were kept and was disappointed when told we all had our own. Explained was a better electrician than mechanic so first job a regular customer's 900 flap fendered Dodge tandem with a 38' frame style dump behind it, trailer side marker lights out. Check on him in a hour and has cab wiring all opened up, ask if checked the seven way for power, Nope, so had him reassemble the first mess, show him how to use a test light and check the cord, all is good, even had Tail and rear markers just not side markers, tell him to check for broken wires. Back still in half hour this time, has all the trailer wiring from back end to front cut out laying on ground, said thought he found it, one half twist single wrap of electrical tape junction, and from what I could see at the spot he started removal. Had him stop, load his tool tote and go home, FIRED. took a little over an hour for me to reconnect everything and get lights working, double checked cab re-install had to redo that mess.
Long story longer and more boring come in next day truck is back, DOT snagged for a Broken light that afternoon(High lift tagged it) low and behold newbie is BACK, charmed his way BACK into the bosses eye, and was working day shift. Finished job, customer was waiting and left with it to return a short time later marker lights quit again, boss sent Newbie out to check, broken wire, just happened to be on the light he just installed, so he repaired and boss had me go look, reason it broke was HE wired UNDER the trailer frame as was easier than fishing it back thru the tube it had been run thru Then I raised the dump tore the wire in half with him standing there. He looked perplexed, said did not know that was how that bed worked. Boss was right behind him and fired him on the spot. I got to fix it AGAIN, the guy was only charged parts, when I rang up ticket night before only charged a flat hour, could not justify more.
Short ending, In today's market with all the high tech stuff I would HATE to try to open or even buy out a existing shop and keep it running efficiently.
