Is working/shadowing contractors a good/bad idea?

[Nick Taylor]

I wanted to jump in and see if I can just start learning. Not sure if its possible for me to shadow or work a little with contractors part time? I am guessing that there may be training involved, and I am already working Mon-Thur. So my guess is this won't work, but just curious if anyone out there has tried anything like this to learn a little about repair costs, materials, what goes on behind the scenes with contractors, how to fix things etc...  TIA
