When our DD1 finished her Degree and could not find a job straightaway- I suggested she did a PGCE (1 year post grad teaching qualification)- she looked at me and laughed, and laughed and laughed some more.
I asked her why and her answer was clear 'mum, she said, I watched you prepare, mark and do school reports, night after night for all those years- and I watched you come home totally exhausted and sometimes in tears' and there is NO way I worked so hard to get a good Degree to do the same- NO WAY'.
She now works very hard, long hours, 5 weeks holiday- but she never has to deal with a Set5 class of 15 year olds on a Friday afternoon after PE...
and she earns about 10 times the salary of a teacher. Same for the other daughter, although she gave up Uni after one year and found another route to a great career.
What sort of people do we want to teach our grand-kids- those who can't access anything else, or those who are the brightest, and who'd choose teaching because they love it- despite a much lower salary? I know compared to many, a teacher salary looks quite good- but don't forget it takes 2 years in 6th Form + 4 years of study to become one- and the good ones would have openings on much higher paid careers.
