i have just finished my 4 year apprenticeship having started it at just turned 16 and left school. wasnt 100% sure it was what i wanted to do, but manged to get a position with a good company and havent looked back since! definitely the best thing ive ever done! i find it really interesting but then do see other apprentices that cant be asked and like you say are just always on phones ect. I can see alot of these people doing just for something to do, but there are still a few like myself who are keen and passionate about the trade, cheers!
