When we were at tech, at the end of each semester, we'd go an work in various sections of the company - it was called field training.
I recall I had to do some testing on an international submarine communications cable. I was a 17-yo first year trainee and wasn't sure of the procedure so I asked one of the qualified techs. He was not happy - "If I have to show you how to do it, I might as well do it myself!"
Many years later, I was his supervisor. [biggrin]
