The position of apprentice.
Form of training where young workers, “apprentices”, are taken on by an employer and trained over a number of years to a given level of competence in a particular trade or profession. Training can be a mixture of on-the-job and off-the-job training.
Apprenticeships began with medieval craft guilds, where for seven years an apprentice lived with a master before becoming a journeyman and employed for a wage.
