Stockman more than Material Handler?

I was approached today by a fellow electrician who was concerned about a Stockman doing more than material handling. Specifically assisting a core driller with his work. Here is what the Stockman’s Agreement has to say in section 2.10:

…The Stockman may do labor tasks, but shall not install or fabricate material, and they shall not assist either a Journeyman Electrician or Apprentice in the performance of their work under the Wireman’s Agreement.
