Our son had done an apprenticeship at a GM dealer while he was in HS auto shop. All the techs were telling him to NOT get into this line of work for all the reasons mentioned in the video. He's now a HydroVac operator. Our youngest works on heavy equipment. He started at a couple of "dealer" shops and had to buy like $30k in tools. After getting his red seal certification, he now works for Cat at a mine that he is flown into, housed, fed, and he uses THEIR tools. He is making money hand over fist, however it's at the expense (sort of) of family time where he's gone for two weeks and back home for two weeks.
One thing that wasn't talked a lot in the video is the thousands in tools and equipment that techs have to buy and pay themselves so right from the get go, they're saddled with huge debt. How many professions do you know of where the employer doesn't supply the tools required for the work? Imagine a soldier, cop or firefighter having to buy all their equipment? Or office workers that would have to buy their computers and printers? etc. I don't get that.
The year I worked at a dealership, I never saw such a bunch of unhappy people not caring for the work they did. Sad really.
All workers should be paid a fair hourly wage (including restaurant staff and get rid of this tipping BS!).
