Am I right that I can't be expected to attend a full INSET day on a day that I don't work?
It's OK to miss Monday, but there was no real response to which INSETS I should attend so I think I'll leave that for another week or two and then check again. How does that sound?
Of course. For the first 7 years in my current post I was holding down 3 (very different) part time jobs. It was understood at school the while I valued training it had to be within the confines of my other responsibilities. I was promoted twice in this time. I also delivered a lot of Inset. My commitment was never intertwined with my availability; they paid me a fraction of the full time salary, I delivered a (slightly bigger) fraction of my time.
I'm now in a senior leadership role, but I'm still not quite full time. My PT status hasn't held up my promotion prospects, nor my commitment. It's a dance, a balancing act, and you will both need to be in time. But don't feel that they have full demands on you.
Is there an assistant head i/c staff development you can talk to? Rather than the Head? I fully appreciate the need to please, I will always have it, but there may be a person with a remit to work through this with you with a less pressing diary.
