Another personal anecdote.I oftenly hear stories that you could even get an office job with just a high school diploma, unlike today where you see the minimum job requirement is a four year college degree plus a minumum of a year or two experience (EVEN FOR AN ENTRY LEVEL POSITION!!).
My parents married in the fall of 1960, the day before my mother's 17th birthday. So she was still 16 when she married (no, it was not a shotgun wedding as some of her gossiping "aunties" whispered around the family); I wasn't born for another 3 years and I have no siblings).
My mother never finished high school. She had a Grade 10 education and quit school as soon as she was legally able to (age 16).
There are reasons, of course, some of which I started to figure out but were confirmed by my aunt after my mother died. My mother was trying to escape an abusive situation at home, so an early marriage ASAP made sense to her. My dad was 25 at the time, and they moved onto the acreage where my grandparents were already living.
My grandmother expected my mother to be a "proper housewife" but my mother wanted to have a job. Good luck with anything decent, being 2 years underage and no high school diploma.
So she took a bookkeeping course through a local secretarial school. That got her in the door to bookkeeping jobs at a car dealership, a motel (started out doing laundry and cleaning there but they promoted her when they found out she could do bookkeeping), and a hotel doing front desk work and bookkeeping. Then she got fired for "not being bubbly enough" and her job was given to a 20-year-younger woman with a fraction of the experience. My mother took them to court and won.
She didn't go back there, though. The last job she had before the cancer took over was as a clerk at a convenience store that also had gas pumps.
My mother and grandparents clashed on a number of things. My grandmother expected that after the divorce that my mother would return to live with her parents and use her maiden name. My mother refused on both counts.
So while my mother did have a variety of low-paid jobs for awhile (clerking in a clothing store was in there somewhere and she tried selling AmWay), that one secretarial course was enough to let her have jobs where she could learn as she went along, and either get promoted or get a higher level of responsibility when she changed jobs.
