The people who 'get ' it will never persuade the people who don't.
I taught for many years, but there is no way that I would choose to do it now.
I divided my monthly salary by the number of hours worked each week and my hourly rate was roughly £10 per hour. That's for an experienced teacher, with senior leadership responsibilities, managing a large team, with postgraduate qualifications.
There will be a time and not too far away, when there will be few or no qualified teachers in our schools. There will be people without teaching qualifications or experience, whilst the academy bigwigs make up their own rules and take their vast salaries.
It's been said and said and said, ever since I was a newly qualified teacher and before. If it's such a great job, go and do it. On the other hand, you could look at teacher websites and consider the numbers leaving the profession, being driven out because they're too expensive, or simply having health breakdowns. They will all, almost without exception, say that they enjoy teaching the children- after all, that's what they thought they would be doing when they signed up- but they loathe absolutely everything else that comes with the job these days.
