I had a Saturday job at 15 in a rather grubby grocery shop. The cheese was processed stuff, I know my mother wouldn't have shopped there, but it was 15/- for the day which was ok in 1961. I'd picked rasps in the school holidays before that.
My first full time job was as a clerk in the corporation rates office. I remember being quite shocked when a colleague had to leave because she was getting married! I also remember what it was like as a young, miniskirted, long legged, fairly innocent girl walking through an office full of blokes to get to the room where the women worked! Once I got over the initial embarrassment we had a laugh.
