My own experience of teaching is very limited. I spent most of my working life as a legal secretary but, about ten years ago, re-trained as a literacy teacher in adult education.
I enjoyed the teaching very much - this was probably partly due to the fact that my students were willing and eager participants. However, as I am sure other teachers will testify, there were huge amounts of paperwork - detailed Schedules of Work to be prepared each term, detailed lesson plans each lesson, lesson material to be prepared and photocopied, individual learning plans, homework to be marked, etc., etc. I was employed on a sessional basis and on the face of it the hourly rate was good. But once I'd taken into account travel to and from each teaching centre, speaking to students after the class, doing all the aforesaid paperwork, I worked out that I was being paid about £4 or less an hour.
I too had previously thought that teachers were quite fortunate, with a short working day and long holidays, but the reality is that a good proportion of work that is done by conscientious teachers (and I think most of them are) is outside the classroom and can amount to many hours.
I was lucky to have taught adult students, who were courteous, keen and appreciative. I did have one experience of being allocated a small group of young people who, for whatever reason, had dropped out of formal education. This was a very different experience - extremely challenging. I'm sure that teaching a large class of younger students must be very demanding and I can understand how teachers can finally "burn out".
In the end, I decided to return to secretarial work because I felt like I was working quite long hours and yet - with all the additional travelling, preparation, etc. - only being paid around £400 a month. As we still had a substantial mortgage at that time, it really wasn't sustainable.
Nowadays it seems that teachers are criticised for everything and, although some parents are appreciative of their efforts, the media seems to take every opportunity to belittle what they do and blame them for things that are often outside their control.
