I worked in the local sweet shop for three evenings while I was in the sixth form and was paid 3/6 a session. It put me off sweets for life, but not chocolate! I also worked at M&S one Christmas for two weeks and was mortified when I was put on Men's underwear!
Once I had got my degree, I was able to do some supply teaching in local primary and infants schools, prior to doing my teaching diploma, which was fun, more lucrative and I was able to make contributions towards my future teacher's pension.
Our daughter worked every summer holiday from the age of 13or14. She always worked at the Oxford College where my husband worked
until he retired, at first, just going in to make hot chocolate for the students on the summer foreign students course, then gradually progressing to being a monitor and taking them on trips, meeting them at the airport etc. She finished up, after she got her degree, by teaching history of art to American students on the Summer English course, which was very lucrative.
