"Putting up backing paper, laminating, stapling things to walls?" - yes, but those are 5 minute jobs, which come at the end of the much more worthwhile and useful task of planning the display which is my job. By the time I have communicated to another member of staff what I want put where, the thing could be up. Waste of both of our times to spend time communicating which would have got the job done.
"Staff and other meetings that may go on late into the evening..." the late ones are rare, but they are driven by critical events around children or staff, or because of a need to address a particular weakness or issue through training or discussion - all part of my job.
"Analysing pupil results is my job Absolutely. Producing analyses on the other hand can be done by anyone with a decent knowledge of Excel." What's the point of a static analysis done by someone else? The whole point is asking the 'what ifs' and seing what effect different screens and filters have, and creating graphs to communicate it clearly. Getting someone else to produce a print-out is about as much use as a chocolate teapot, you need the live Excel stuff to do proper analysis.
"Providing after school clubs is my job" My job is to educate children. because of our catchment, one of the ways of educating children that is needed is to bring them a wider set of experiences that they will not have unless we provide them as a school. We don't have mums who take children to ballet or swimming or drama or football - and that lack of life experience has a huge impact on children's in-school performance, which it is my job to address. Not in all schools, I agree, but in ours, it is part of the teaching job.
"Getting feedback on my teaching, through observations that are as regular as necessary, is my job" I teach the full NC. I am better at some subjects than others. I am entirely happy to e.g. be observed in several subjects each term, in order that I get better. If there is only 1 observation, of a single subject, each term, I do not believe that my teaching would improve across the board as much as it could.
"Chasing up absence is my job" If Little Johnny is regularly absent from school and it is causing educational issues, then you might wish to liaise with parents or Little Johnny on the matter ... exactly, that is what i was thinking of when I said it was my job
