The trick with apprentices is to find one who actually wants to make a career of his (her) trade. The difficulty is (colleges) getting everyone training a "job" and that means a lot of dead wood (left school with no clear idea what to do - taking an apprenticeship cos "best mate" did) ending up working for a trade they have no enthusiasm for. And the pay for apprentices is always going to be low - how much can you afford to pay someone (who until they learn their trade) who can load/unload the van, carry a few materials about the site, and just about load a skip?
