6-8 hours a week for first semester freshmen and up to 12for more experienced students gives them a lot of skills. Just looking for the job teaches them something, doing it day after day is a lesson in itself too. I had a friend who thought every uppermiddle/ middle class kid should have a menial on campus job for one semester, as an empathy experience and also as a concrete example of what their next 50years will be if they don’t do well in college. I must say that the technique, applied to a few “comfortable” kids, some with ao-so work habits and some with a certain sense of entitlement to boot, Surprisingly worked wonders.
