WWYD? Meeting dilemma

[EvilTwins]

I have a staff meeting tomorrow. We have meetings every Monday. This meeting was due to be led by the (lovely) deputy head but now he's not going to be in school do is going to be led by the HT instead. She's usually ok BUT has a bee in her bonnet about people missing stuff because of their own DC. I have to get my own kids to a concert ( they are performing) for 4pm which would mean leaving the meeting pretty much as soon as it's started. Would you
A) tell her up front (last time I had to leave something early because of DC her response was "no it's not ok, but there's not much I can do is there?"
B) invent an emergency and HAVE to leave without giving up-front notice
C) something else I haven't managed to think of yet.

One of the reasons I am strongly considering giving up secondary teaching. It's a constant battle as DS is disabled so childcare is v v limited, after school meetings are a nightmare (and parents eves, open eves, concerts, trips....)

I would arrange for someone else to drop your children off at the concert and attend the meeting for the duration.

There wasn't anyone else who could do it - I made that pretty clear up thread. It was fine. I spoke to her. She said it was ok - that the content part of the meeting wouldn't go on for the full hour anyway. So I got the kids to the theatre for about 4.15. Everyone was happy. I already do a hell of a lot more than is expected of me at work. My line manager and the SLT recognise this. Thank goodness they are a little better qualified to assess my professionalism than a bunch of judgey strangers on MN!

"judgey strangers" - you did ask!

True

I thought some of the responses were a bit rude!! Just my opinion!

I was a bit abrupt in my post. I was being a right mardy arse. Sorry.

We are lucky that our HT often tells us to put our families first. He knows that it means we are more committed to school in the long term as we feel supported.
