Apprentices are usually kept busy for several reasons. For starters, you're cheap labor for the contractor and the local wants to keep you busy so that you will gain the experience needed to fulfill the requirements to become a journeyman.
Book 1 is the out of work book for journeyman members of the local (apprentices do not sign this book). Book 2 is usually for those that are not members of the local (usually traveling brothers) . Work is dispatched Book 1 first and if the call is not filled, then people from Book 2 are dispatched.
Good luck
