Primary teacher here...I'm 59 and will be retiring soon. I've been teaching for 30 years and, as someone has already pointed out, teachers are leaving in droves. There's a VERY good reason for this!
When I started teaching, I absolutely loved my job...truly! I couldn't ever imagine doing anything else. Every day was a blessing...the children were delightful, my colleagues were happy and fulfilled in their roles and our job was to teach. Of course we did other things too...and did so willingly as there was time to do so. I would get into school at 8.15 and would have finished all my jobs by 5 at the latest. I didn't have any work to do after school...everything was done in school. Very occasionally I might have paperwork to do, but this was at certain times of the year (report writing in the summer for example).
Fast forward to now...education is a mess! Teaching is just a small part of what we do...probably the smallest part if I'm honest! Once the 'teaching' part of our day is done, we start the rest of our job...which takes just as long...so, you teach for around 6 hours, then you have a similar amount of 'other shit' to do as an absolute expectation! It's exhausting and soul destroying. Nothing you do is good enough. As a minimum I'm now working 65 hours a week...but often much more than this. It is not a job that fits well with family life.
It has been declining over the past 15 years I'd say...but has accelerated exponentially in the past 3 years, to the point where it is no longer fit for purpose.
I will be retiring in April 2024 and honestly will not look back. I would NEVER recommend teaching as a career...which makes me very sad. I can't believe that the job I loved so passionately for so long, is now one that is destroying so many wonderful, caring individuals. But here we are!
