The first electrician I worked for was very cheap and always was in a rush to get work done. He couldn't make money if we weren't hustling. He would cut corners where ever he could to wind up being penny wise and pound foolish. The best part about working for him was that he didn't want to look in the code book anymore. If we got to a job that was difficult, he made me look up the answer. Then he would ask me what to do. That made me learn how to read the code book. I learned where thing were in the code book and why they were there. When I had men, I needed to be quick also, but I told my men that I would be more than happy to go over any questions that they had about the code. Then the shoe was on the other foot. The would love to hear me preach and teach the code on my time, but the never could/would stay a few minutes late to learn new codes. Of the many employees I had, 3 of them got their contractors license. I was proud of those guys.
