I look at it a little differnt.
apprenticeship = some one taking a trade (building work and so forth)
interns are for people with a degree and dont have the rights as a full time worker.
volunteer are people who dont have a degree and try and get on the job ladder but have better rights then someone doing a intern.
charity work is for anyone who helps out a charity
