We've all seen this sort of stuff before
You can't trust some people to do up their own shoelaces!
I think it's genetic some people just can't do it, they know this but don't give a @#!$
not just Electrical Trainee's as I have met a few very conscientious ones,
It happens across the board we've all met apprentice trained people your afraid to stand next to when they're working
My mate says it's Nature as in the stupid ones take risks that can kill them
He says H&S goes against Darwin's theory and allows these idiots to thrive by protecting them from themselves and the intelligent ones are becoming endangered as they're outnumbered by numptys creating lethal situations
ie in the past Stupid John the village idiot often met a nasty end due to bad judgement and his stupid genes die out
Unfortunately these idiots leave a trail of danger behind them before they get a wake up call
I've met lots of people all chancing their hand at something they think will earn them mega bucks, all talk and No substance
Tbh I think that asides from stricter skills tests, practical and theory being the best long term solution,
The only way of stopping it would be having compulsory licensing and third party inspection for certain grades of workers in the electrical trades but I guess this would get watered down when not enough people passed
To the OP
I've also heard that in Germany you are licensed to a certain grade and have to complete a business course before you can go self employed, therefore only the proven can tout their trade independently
If this is true it would be a good system to adopt.
