I'm in a job share. Colleague was made subject leader of the area we work in, last year. It has been an utter disaster, with dire results. Appraisal targets were data led and the class utterly bombed.
I don't know what I could have done to avert it. I advised HT of situation, and even tried to resign as I was so fed up working around dire planning and teaching. Nothing was done. Long standing issues with support staff have not been tackled, either.
The appraisal comments on recent improvements. This coincides with my taking on full responsibility for planning, despite being part time. All my obs have been good with os features. HT admits she now realises situation and has no idea what I could have done.
New targets are also data led and I believe I can just about make them, as job share due on mat leave shortly. Will be tight, though.
So .. I am doing whole school stuff, I am doing all the assessment and most of the planning for my class for part time pay, I have been consistently good for LEA, HMI and all the other crew under intolerable pressure - and I am taking an effective cut because management refused to deal with my under performing colleagues.
I am incredibly frustrated.
