technically lol, it isn't any of your business - unless you do ring the lea and volunteer to be a community governor, in which case you will be helping to make the appropriate decisions and defending them to random punters who ring up... your friend who does have kids at the school, is of course, perfectly within her rights to make contact through the appropriate channels... but tbh i'm really surprised the chair of govs hasn't already issued at least one letter to all school parents in view of the fact it seems to be in the papers lol, even if it is a 'we are aware and are taking guidance from the lea and will fill you in when a decision has been made' type letter... but you wouldn't know if that had been done?... i suspect the lea will have had their fill of press well meaning citizens ringing up and trying to squeeze salacious detail from them, or expressing their righteous indignation at the undoubted horror of events.
it's great you are so concerned, honestly, but without anything to get concerned about (ie no direct reason to get involved - not sure how old your dcs are or what your local situation is in respect to school applications/ catchments - whether they are likely in the near future to fetch up there, or whether the school will have changed beyond all recognition by that dim and distant point), you'll just look like a daily mirror reader when you ring up (even worse than the mail lol), which wouldn't be great.
you can make a difference to a local school, but not by getting involved in a campaign to get rid of a headteacher you know nothing about, because of something you read in the paper. that way madness lies.
and i should know
leave it to the people who are already involved - there's obviously plenty of twittering going on already. the best thing you can do is tell your friend to stop whittering about it and ring the chair of governors to register the concerns of the parents. that would be your appropriate course of action with regard to this incident.
now what am i doing? this isn't an advice thread, it's an aibu...
ah well.
