Various threads on this forum bemoan the lack of training, the skinflint levels of pay (agencies offering £7 an hour etc), and the difficulties new starters face getting into the business. The world's changed, maybe not for the better, but nowadays this, here, is where people turn for advice and the benefit of others' experience. If the OP had some wise old man, a village elder of electrics, to turn to he wouldn't have asked the question here. The internet and forums such as this are the new "wise old men".
I've learned things on here, and I'm happy when I can pass them on to others. If you can't respond without resorting to trashing a complete stranger it might be better not to respond at all.
