Now here is a flip flop. Most of everything built today is built on the backs of tradesmen. Most very talented and knowledgeable.
I must mention I work with some real dingalings. Managementhired this one fella because he had a unverisity degree in Engineering and was susposedly knowledge of tools.
Sadly when I asked him for a Phillips screw driver. He did not know the difference. Instead he handed me all of them.
I left him to do a simple job of screwing door stops in the floor. I came back and found he broke several screws (robertson screws The ones with the square hole in the screw head) Most of the ones he put in the holes were round, not square. I looked at the screw driver bit in the cordless drill. It too was rounded and the metal of the bit and some of the screws were blue in color from over heating. He only did 5 doorstops.
Needless to say. The rest of us trades people went after management to get rid of this guy for his safety and ours. Which they did.
I too work with some tradesmen that I would not trust to build a house.
I have one that got his level 3 boiler papers. . But in the actual enviroment he was lost. Even when asked questions his explainations were off the wall. I knew about him before he got hired and his previous employer and why they got rid of him.
When I heard they were hiring him. I voiced about I knew of his work and not to hire him. They did anyways. I refuse to work with him. and when I have. he cannot even follow the simplest directions. He is the one that hangs picture crocked.
So not all tradesmen are that great either. Some manage to slip through.

 

Very good video. I wish there was more like that when I was going thru school.
