I was an electronics technician for a casino(no don’t ask which, to much identifying info doing that!) and we had 3 levels of slot tech.
Floor monkey… smart enough to pour pee out of a boot with instruction on the heel, would probably pour it on themselves…
Junior tech… smart enough to do minor repairs/swap entire monitors or cpu boards
Senior tech(what I was)… college degree, prior electronics repair experience, willing to tackle unusual projects and find a solution that was cost effective then get it done on time using the junior techs as grunt labor while the floor monkeys did the bulk of the stupid customer repair calls that were customer error 90% of the time.
Floor Monkeys were hired in bulk, many didn’t last a day, some made it a week… 1 of 20 would last a year and maybe work up to a junior tech
Junior Techs we would maybe keep 1 out of 10 after 6 months
Senior techs it was 1 out of 3 lasted. Hours sucked, job was extremely high stress, pay was okay, not great, made a decent living… I did it for 6 years before retiring.
Boss hired a new senior tech… introduces him to me. I was working on a large format picture tube style monitor with 50,000 volts on the anode. I had the anode insulator folded back and was monitoring voltage with a scope to try and catch the glitch that was rebooting the slot machine.
New brainiac walked up and asked what I was working on(clue #1)… um a monitor?
He asks what is this? As he sticks his finger into 50,000 volts.
He lasted 15 minutes. When he woke up after being tossed 10 feet into the wall my boss fired him for being an idiot…
